Daniel Hannan on the selfishness of running a deficit and post-truth realities

In the latest Ici Londres production Dan Hannan looks at the morality of deficits.

Daniel Hannan starts by quoting Matthew 7:9-10

If the son shall ask bread of any of you that is a father, will you give him a stone? Or if he asks for a fish will you give him a serpent?

The passage goes onto to say the if you are evil, understand how to give good gifts to your children. By implication, to act for good, we must also understand how to act for the good, not just have the moral injunction.

Hannan goes onto say we do not run up large debts to bequeath to our children. Yet many impose a very different standard as voters, convincing themselves that they are being unselfish. By asking for more money from the State, whether to pay for care in old age or for a pay rise in the public sector, or remission of tuition fees, it might be a very good claim, but it is not an intrinsically unselfish claim, as they are asking for everybody else to chip in and pay for their cause. Conversely those who try to impose some fiscal discipline are deemed selfish. They are standing up for future generations. Austerity is not a random preference but a simple reality.

This is all pretty obvious stuff to anyone who understands basic morality and the slightest notion of finance. It is certainly within the understanding of anybody who has been brought up in a traditional British public school education. But I would suggest it is totally alien to the vast majority of the British public. This reason is described by a new word that entered the Oxford English Dictionary last month.

post-truth

Relating to or denoting circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.

The General Election campaign is a clear illustration of the domination of post-truthers in public life. There is no understanding of public finances, just mass beliefs that are not based on any moral tradition. The spread of the beliefs is on social media, driven by those who most forcefully and repeatedly express their ideas. People are wrong because they disagree with the mass beliefs and shouted down (or trolled in the electronic version) because of it.

In a post last month – General Election 2017 is a victory for the Alpha Trolls over Serving One’s Country – I concluded

It is on the issue of policy to combat climate change that there is greatest cross-party consensus, and the greatest concentration of alpha trolls. It is also where there is the clearest illustration of policy that is objectively useless and harmful to the people of this country.

Like with public finances, climate change is an where post-truthers dominate. Two examples to illustrate.

Consensus messaging

There is no clear evidence of an emerging large human-caused problem with climate and there is no prospect of action to reduce greenhouse has emissions to near zero. Instead we have a dodgy survey that claimed 97% of academic papers on an internet search matching the topics ‘global climate change’ or ‘global warming’ expressed support (belief / assumptions) in the broadest, most banal, form of the global warming hypothesis. This was converted by Senator Bernie Sanders, in questioning Scott Pruitt, into the following:-

As you may know, some 97% of scientists who have written articles for peer-reviewed journals have concluded that climate change is real, it is caused by human activity, and it is already causing devastating problems in the US and around the world.

And

While you are not certain, the vast majority of scientists are telling us that if we do not get our act together and transform out energy system away from fossil fuel there is a real question as to the quality of the planet that we are going to be leaving our children and our grandchildren. 

The conversion from banal belief to these sweeping statements is not the fault of the Senator, though he (or his speech-writers) should have checked. Rather it is of lead author John Cook and his then PhD supervisor Cognitive Psychology Professor Stephan Lewandowsky. Post-truthers will not recognize the glaring difference between the dodgy survey and the Senator’s statements, as it is appeals to emotion and belief that are primary in evaluating political realities.

Mitigating Climate Change

Dangerous climate change is allegedly caused by human greenhouse emissions. The proposed solution is to reduce those emissions (mostly CO2 emissions from the burning of fossil fuels) to near zero. The key for policy is that emissions are global, yet most countries, covering over 80% of the global population have no primary obligation under the 1992 Rio Declaration to reduce their emissions. These developing “non-Annex” countries have accounted for all the in emissions since 1990, as shown in this graph.

The problem can be expressed in my First Law of Climate Mitigation

To reduce global greenhouse gas emissions, the aggregate reduction in countries that reduce their emissions must be greater than aggregate increase in emissions in all other countries.

All the ranting about supporting the Paris Agreement ignores this truism. As a result, countries like the UK who pursue climate mitigation will increase their energy costs and make life harder for the people, whilst not achieving the policy aims. It is the poorest in those policy countries who will bear the biggest burden and create comparative disadvantages compared to the non-policy countries. For the developing countries (shown in purple in the graph) to reduce their emissions would destroy their economic growth, thus preventing the slow climb out of extreme poverty still endured by the majority of people on this planet. In so doing we ignore the moral tradition from our Christian heritage that the primary moral concern of public policy should be the help the poor, the disadvantaged and the marginalized. Ignoring the truism and pursuing bequeaths a worse future for our children and our grandchildren. This is the same for climate change as for public finances. But in both cases it is the post-truth “reality” that prevent this recognition of basic logic and wider morality.

Time will run out to prevent 2°C warming barrier being breached

I have a number of times referred to a graphic “Figure 2 Summary of Results” produced by the UNFCCC for the Paris COP21 Climate Conference in December 2015. It was a centerpiece of the UNFCCC Synthesis report on the aggregate effect of INDCs.

The updated graphic (listed as Figure 2, below the Main Document pdf) is below

This shows in yellow the impact of the INDC submissions covering the period 2015 to 2030) if fully implemented against limiting warming to 2°C  and 1.5°C . This showed the gulf between the vague policy reality and the targets. Simply put, the net result of the INDCs submissions would insufficient for global emissions to peal Yet in reaching an “agreement” the representatives of the entire world collectively put off recognizing that gulf.

For the launch of the UNIPCC AR5 synthesis report in 2014, there were produced a set of slides to briefly illustrate the policy problem. This is slide 20 of 35, showing the  reduction pathways.

 

The 2°C  of warming central estimate is based upon total GHG emissions in the 21st Century being around 2500 GtCO2e.

At the launch of 2006 Stern Review Sir Nicholas Stern did a short Powerpoint presentation. Slide 4 of the PDF file is below.

 

The 450ppm CO2e emissions pathway is commensurate with 2°C  of warming. This is based upon total GHG emissions in the 21st Century being around 2000 GtCO2e, with the other 500 GtCO2e presumably coming in the 22nd Century.

The UNFCCC Paris graphic is also based on 2500 GtCO2e it is also possible to calculate the emissions reduction pathway if we assume (a) All INDC commitments are met (b) Forecasts are correct (c) no additional mitigation policies are enacted.

I have produced a basic graph showing the three different scenarios.

The Stern Review assumed global mitigation policy would be enacted around 2010. Cumulative 21st Century emissions would then have been around 450 GtCO2e. With 500 GtCO2e allowed for post 2100, this gave average emissions of around 17 GtCO2e per annum for the rest of the century. 17 GtCO2e, is just under 40% of the emissions in the year the policy would be enacted.

IPCC AR5  assumed global mitigation policy would be enacted around 2020. Cumulative 21st Century emissions would then have been around 950 GtCO2e. A presentation to launch the Synthesis Report rounded this to 1000 GtCO2e as shown in slide 33 of 35.

Assuming that global emissions were brought to zero by the end of the century, this gave average emissions of 20 GtCO2e per annum for the rest of the century. 20 GtCO2e, is just under 40% of the emissions in the year the theoretical global policy would be enacted. The stronger assumption of global emissions being reduced to zero before the end of the century, along with a bit of rounding, offsets the delay.

If the Paris Agreement had been fully implemented, then by 2030 cumulative 21st Century emissions would have around 1500 GtCO2e, leaving average emissions of around 14 GtCO2e per annum for the rest of the century. 17 GtCO2e, is just over 25% of the emissions in the year the policy would be enacted. The failure of the Paris Agreement makes it necessary for true global mitigation policies, if in place by 2030, to be far more drastic that those of just a few years before to achieve the same target.

But the Paris Agreement will not be fully implemented. As Manhatten Contrarian (hattip The GWPF) states, the US was the only major country proposing to reduce its emissions. It looks like China, India, Indonesia, Russia and Germany will all increase their emissions. Further, there is no indication that most countries have any intention of drastically reduce their emissions. To pretend otherwise is to ignore a truism, what I will term the First Law of Climate Mitigation

To reduce global greenhouse gas emissions, the aggregate reduction in countries that reduce their emissions must be greater than aggregate increase in emissions in all other countries.

Modeled projections and targets are rendered meaningless if this truism is ignored. Yet this is what the proposers of climate mitigation policy have been effectively doing for many years. Emissions will therefore breach the mythical 2°C warming barrier, but based on recent data I believe warming will be nowhere near that level.

The Closest yet to my perspective on Climate Change

 Michael S. Bernstam of the Hoover Institution has produced a short post Inconvenient Math. (hattip The GWPF). The opening paragraphs are:-

Climate change faces a neglected actuarial problem. Too many conditions must be met to warrant a policy action on climate change. The following four stipulations must each be highly probable:

1. Global warming will accumulate at 0.12 degrees Celsius or higher per decade.

2. It is anthropogenic, due largely to carbon dioxide emissions.

3. The net effect is harmful to human well-being in the long run.

4. Preventive measures are efficient, that is, feasible at the costs not exceed-ing the benefits.

But even if the probability of each of these stipulations is as high as 85 percent, their compound probability is as low as 50 percent. This makes a decision to act or not to act on climate change equivalent to flipping a coin.

Bernstam later states

In the case of climate change, the conditions are four. They are not random, nor are they arbitrary. To see this, one can run a thought experiment and drop or ignore any of the above foursome. At once, the entire call for action on climate change becomes pointless. If global warming is not ongoing, there is no need to stop it. If it is not anthropogenic, there is no need to curb carbon dioxide emissions. If it is not harmful, there is no need to worry. If preventive measures are inefficient, they would not help and there is no use applying them. It follows that all four conditions are necessary. If just one of them does not hold, action is unnecessary or useless.

That is, for action on climate change to be justified (in terms of having a reasonable expectation that by acting to combat climate change a better future will be created than by not acting) there must be human-caused warming of sufficient magnitude to produce harmful consequences, AND measures that cost less than the expected future costs that they offset.

These sentiments are a simplified version of a series of posts I made in October 2013, where I very crudely deriving two cost curves (costs of climate change and climate mitigation). This aimed to replicate a takeaway quote from the Stern Review.

Using the results from formal economic models, the Review estimates that if we don’t act, the overall costs and risks of climate change will be equivalent to losing at least 5% of global GDP each year, now and forever. If a wider range of risks and impacts is taken into account, the estimates of damage could rise to 20% of GDP or more. In contrast, the costs of action – reducing greenhouse gas emissions to avoid the worst impacts of climate change – can be limited to around 1% of global GDP each year.

I looked at the idea of multiplying the various probabilities together, at least for the costs of climate change.  But instead of the boundary it is a continuous function of an infinite number of possible scenarios. In general I believe the more extreme the costs of warming, the less likely it is to happen. The reason is that we derive the non-visible part of the cost curve can only be objectively derived from the revealed warming from the recent past. Separation of the costs of warming-induced climate change are extremely difficult from the costs of random extreme weather events. Even worse, the costs of extreme natural weather events (especially in terms of death toll) has been falling over time, as Indur Goklany has documented. The fall-back for global-warming theory is to use the late Milton Friedman’s Methodology of Positive Economics. That is to evaluate theory credibility on its predictive ability. If in the short-run climate scientists (or anyone who believes in climate alarmism like Al Gore) are able to make predictions about the signals of impending climate apocalypse, then this should give some credibility for claims of substantially worse to come. The problem is there are a huge number of failed predictions of climate worsening, but not a single one that has come true. This would signify that the true risk (as opposed to the perceived risk from the climate community) of climate change is approximately zero. The divergence of belief from the evidence is likely from the collective navel-gazing of post normal science.

The policy aspect that Bernstam fails to explore is the re-distributional aspects of policy. The theory is that global warming is caused by global greenhouse gas emissions. Therefore climate mitigation must comprise of reducing those global emissions. However, as the COP21 Paris showed most of the worlds population live in countries where there are no GHG emissions reduction policies even proposed. But actually reducing emissions means increasing energy costs, and hampering businesses with onerous regulations. Policy countries are given a comparative disadvantage to non-policy countries, as I tried to show here. The implication is that if developed countries strongly pursue high cost mitigation policies, the marginal cost of non-policy emerging economies switching to emissions reduction policies increases. Thus, whilst Donald Trump’s famous tweet that Global Warming is a Chinese hoax to make US manufacturing non-competitive is false, the impact of climate mitigation policies as currently pursued are the same as if it were true.

There is also a paradox with the costs of climate change. The costs of climate change are largely related to the unexpected nature of the costly events. For instance, ceteris paribus. a category 1 hurricane could be more costly in a non-hurricane area than a stronger hurricane in say Florida. The reason is that in the non-hurricane area buildings will not be as resistant to storms, nor will there be early warning procedures in place as in Florida. The paradox is that more successful climate scientists are in forecasting the risks of climate change, the more people can adapt to climate change, reducing the costs. The current focus on climate consensus, rather than focusing on increasing competency and developing real expertise in the field is actually harmful to future generations if climate change is a actually a serious emerging problem. But the challenge for the climate alarmists is that in developing the real expertise may result in their beliefs about the world are false.

Finally, Bernstam fails to acknowledge an immutable law of public policy. Large complex public policy projects with vague aims; poorly defined plans and lack of measurable costs tend to overshoot on costs and under-perform of benefits. Climate mitigation is an extreme example of complexity, lack of clear objects and lack object measurement of costs per unit of emissions saved.

Joe Romm inadvertently exposes why Paris Climate Agreement aims are unachievable

Summary

Joe Romm promotes a myth that the Paris Climate Agreement will make a huge difference to future greenhouse gas emissions. Below I show how the modelled impact of think tank Climate Interactive conclusion of a large difference is based on emissions forecasts of implausible large emissions growth in policy countries, and low emissions growth in the non-policy developing countries.

 

In the previous post I looked at how blogger Joe Romm falsely rebutted a claim that President Donald Trump had made that the Paris climate deal would only reduce only reduce future warming in 2100 by a mere 0.2°C. Romm was wrong on two fronts. He first did not check the data behind his assertions and second,  in comparing two papers by the same organisation he did not actually read the explanation in the later paper on how it differed from the first. In this post I look at how he has swallowed whole the fiction of bogus forecasts, that means the mere act of world leaders signing a bit of paper leads to huge changes in forecast emissions.

In his post  Trump falsely claims Paris deal has a minimal impact on warming, Romm states

In a speech from the White House Rose Garden filled with thorny lies and misleading statements, one pricks the most: Trump claimed that the Paris climate deal would only reduce future warming in 2100 by a mere 0.2°C. White House talking points further assert that “according to researchers at MIT, if all member nations met their obligations, the impact on the climate would be negligible… less than .2 degrees Celsius in 2100.”

The Director of MIT’s System Dynamics Group, John Sterman, and his partner at Climate Interactive, Andrew Jones, quickly emailed ThinkProgress to explain, “We are not these researchers and this is not our finding.”

They point out that “our business as usual, reference scenario leads to expected warming by 2100 of 4.2°C. Full implementation of current Paris pledges plus all announced mid-century strategies would reduce expected warming by 2100 to 3.3°C, a difference of 0.9°C [1.6°F].”

The reference scenario is RCP8.5, used in the IPCC AR5 report published in 2013 and 2014. This is essentially a baseline non-policy forecast against which the impact of climate mitigation policies can be judged. The actual RCP website produces emissions estimates by type of greenhouse gas, of which breaks around three-quarters is CO2. The IPCC and Climate Interactive add these different gases together with an estimate of global emissions in 2100. Climate Interactive current estimate as of April 2017 is 137.58 GtCO2e for the the reference scenario and the National Plans will produce 85.66 GTCO2e. These National would allegedly make global emissions 37.7% than they would have been without them, assuming they are extended beyond 2030. Climate Interactive have summarized this in a graph.

To anyone who actually reads the things, this does not make sense. The submissions made prior to the December 2015 COP21 in Paris were mostly political exercises, with very little of real substance from all but a very few countries, such as the United Kingdom. Why it does not make sense becomes clear from the earlier data that I extracted from Climate Interactives’ C-ROADS Climate Simulator version v4.026v.071 around November 2015.  This put the RCP8.5 global GHG emissions estimate in 2100 at the equivalent of 139.3 GtCO2e. But policy is decided and implemented at country level. To determine the impact of policy proposal there must be some sort of breakdown of emissions. C-ROADS does not provide a breakdown by all countries, but does to divide the world into up to 15 countries and regions. One derived break-down is into 7 countries or regions. That is the countries of USA, Russia, China and India, along with the country groups of EU27, Other Developed Countries and Other Developing Countries. Also available are population and GDP historical data and forecasts. Using this RCP8.5 and built-in population forecasts I derived the following GHG emissions per capita for the historical period 1970 to 2012 and the forecast period 2013 to 2100.

Like when I looked at Climate Interactives’ per capita CO2 emissions from fossil fuels estimates at the end of 2015, these forecasts did not make much sense. Given that these emissions are the vast majority of total GHG emissions it is not surprising that the same picture emerges.

In the USA and the EU I can think of no apparent reason for the forecast of per capita emissions to rise when they have been falling since 1973 and 1980 respectively. It would require for energy prices to keep falling, and for all sectors to be needlessly wasteful. The same goes for other developed countries, which along with Canada and Australia, includes the lesser developed countries of Turkey and Mexico. Indeed why would these countries go from per capita emissions similar to the EU27 now to those of the USA in 2100?

In Russia, emissions have risen since the economy bottomed out in the late 1990s following the collapse of communism. It might end up with higher emissions than the USA in 1973 due to the much harsher and extreme climate. But technology has vastly improved in the last half century and it should be the default assumption that it will continue to improve through the century. It looks like someone, or a number of people, have failed to reconcile the country estimate with the forecast decline in population from 143 million in 2010 to 117 million. But more than this, there is something seriously wrong with emission estimates that would imply that the Russian people become evermore inefficient and wasteful in their energy use.

In China there are similar issues. Emissions have increased massively in the last few decades on the back of even more phenomenal growth, that surpasses the growth of any large economy in history. But emissions per capita will likely peak due to economic reasons in the next couple of decades, and probably at a much lower level than the USA in 1973. But like Russia, population is also forecast to be much lower than currently. From a population of 1340 million in 2010, Climate Interactive forecasts population to peak at  1420 million in 2030 (from 2020 to 2030 growth slows to 2 million a year) to 1000 million in 2100. From 2080 (forecast population 1120) to 2100 population is forecast to decline by 6 million a year.

The emissions per capita for India I would suggest are far too low. When made, the high levels of economic growth were predicted to collapse post 2012. When I wrote the previous post on 30th December 2015, to meet the growth forecast for 2010-2015, India’s GDP would have needed to drop by 20% in the next 24 hours. It did not happen, and in the 18 months since actual growth has further widened the gap with forecast. Similarly forecast growth in GHG emissions are far too low. The impact of 1.25 billion people today (and 1.66 billion in 2100) is made largely irrelevant, nicely side-lining a country who has declared economic growth is a priority.

As with the emissions forecast for India, the emissions forecast for other developing countries is far too pessimistic, based again on too pessimistic growth forecasts. This mixed group of countries include the 50+ African nations, plus nearly all of South America. Other countries in the group include Pakistan, Bangladesh, Myanmar, Thailand, Indonesia, Vietnam, Haiti, Trinidad, Iraq, Iran and Kiribati. There are at least a score more I have omitted, in total making up around 42% of the current global population and 62% of the forecast population in 2100. That is 3 billion people today against 7 billion in 2100. A graph summarizing of Climate Interactive’s population figures is below.

This can be compared with total GHG emissions.

For the USA, the EU27, the other Developed countries and China, I have made more reasonable emissions per capita estimates for 2100.

These more reasonable estimates (assuming there is no technological breakthrough that makes zero carbon energy much cheaper than any carbon technology) produce a reduction in projected emissions of the same order of magnitude as the supposed reduction resulting from implementation of the National Plans. However, global emissions will not be this level, as non-policy developing nations are likely to have much higher emissions. Adjusting for this gives my rough estimate for global emissions in 2100.

The overall emissions forecast is not very dissimilar to that of RCP8.5. Only this time the emissions growth has shift dramatically from the policy countries to the non-policy countries. This is consistent with the data from 1990 to 2012, where I found that the net emissions growth was accounted for by the increase in emissions from developing countries who were not signatories to reducing emissions under the 1992 Rio Declaration. As a final chart I have put the revised emission estimates for India and Other Developing Countries to scale alongside Climate Interactives’ Scoreboard graphic at the top of the page.

This clearly shows that the emissions pathway consistent the constraining warming to  2°C will only be attained if the developing world collectively start reducing their emissions in a very few years from now. In reality, the priority of many is continued economic growth, which will see emissions rise for decades.

Concluding Comments

This is a long post, covering a lot of ground. In summary though it shows environmental activist has Joe Romm has failed to check the claims he is promoting. An examination of Climate Interactive (CI) data underlying the claims that current policies will reduce global temperature by 0.9°C through reducing GHG global emissions does not stand up to scrutiny. That 0.9°C claim is based on global emissions being around 35-40% lower than they would have been without policy. Breaking the CI data down into 7 countries and regions reveals that

  • the emissions per capita forecasts for China and Russia show implausibly high levels of emissions growth, when they show peak in a few years.
  • the emissions per capita forecasts for USA and EU27 show emissions increasing after being static or falling for a number of decades.
  • the emissions per capita forecasts for India and Other Developing Countries show emissions increasing as at implausibly lower rates than in recent decades.

The consequence is that by the mere act of signing an agreement makes apparent huge differences to projected future emissions. In reality it is folks playing around with numbers and not achieving anything at all, except higher energy prices and job-destroying regulations. However, it does save the believers in the climate cult from having to recognize the real world. Given the massed hordes of academics and political activists, that is a very big deal indeed.

Joe Romm falsely accuses President Trump understating Impact of Paris Deal on Global Warming

Joe Romm of Climate Progress had a post two weeks ago Trump falsely claims Paris deal has a minimal impact on warming

Romm states

In a speech from the White House Rose Garden filled with thorny lies and misleading statements, one pricks the most: Trump claimed that the Paris climate deal would only reduce future warming in 2100 by a mere 0.2°C. White House talking points further assert that “according to researchers at MIT, if all member nations met their obligations, the impact on the climate would be negligible… less than .2 degrees Celsius in 2100.”

The deeply prejudiced wording, written for an extremely partisan readership, encourages readers to accept the next part without question.

The 0.2°C estimate used by Trump may be from another MIT group; the Joint Program on the Science and Policy of Global Change did have such an estimate in early 2015, before all of the Paris pledges were in. But, their post-Paris 2016 analysis also concluded the impact of the full pledges was closer to 1°C.

The source for the 0.2°C claim is the MIT JOINT PROGRAM ON THE SCIENCE AND POLICY OF GLOBAL CHANGE. ENERGY & CLIMATE OUTLOOK PERSPECTIVES FROM 2015

This states

New in this edition of the Outlook are estimates of the impacts of post-2020 proposals from major countries that were submitted by mid-August 2015 for the UN Conference of Parties (COP21) meeting in Paris in December 2015.

So what INDC submissions were in by Mid-August? From the submissions page (and with the size of total 2010 GHG Emissions from the Country Briefs) we get the following major countries.

In box 4 of the outlook, it is only Korea that is not included in the 0.2°C impact estimate. That is just over half the global emissions are covered in the MIT analysis. But there were more countries who submitted after mid-August.

The major countries include

 
My table is not fully representative, as the UNFCCC did not include country briefs for Nigeria, Egypt, Saudi Arabia, Iran, Iraq, Kuwait and UAE. All these countries made INDC submissions along with a lot of more minor GHG emitters. I would suggest that by mid-August all the major countries that wanted to proclaim how virtuous they are in combating climate change were the early producers of the INDC submissions. Countries like the Gulf States, India and Indonesia tended to slip their documents in somewhat later with a lot of measly words to make it appear that they were proposing far more than token gestures and pleas for subsidies. Therefore, the 0.2°C estimate likely included two-thirds to three-quarters of all the real emission constraint proposals. So how does an analysis a few months later produce almost five times the impact on emissions?

The second paragraph of the page the later article Joe Romm links to clearly states difference in methodology between the two estimates.

 

A useful way to assess that impact is to simulate the effects of policies that extend the Agreement’s 188 pledges (known as Nationally Determined Contributions, or NDCs) to the end of the century. In a new study that takes this approach, a team of climate scientists and economists from the MIT Joint Program on the Science and Policy of Global Change led by research scientist Andrei Sokolov finds that by 2100, the Paris Agreement reduces the SAT considerably, but still exceeds the 2 C goal by about 1 C.

The primary difference is that the earlier study tries to measure the actual, real world, impacts of existing policy, and policy pledges, if those policies are fully enacted. In the USA, those pledges would need Congressional approval to be enacted. The later study takes these submissions, (which were only through to 2030) and tries to estimate the impact if they were extended until 2100.  That is renewables subsidies that push up domestic and business energy costs would be applied for 85 years rather than 15. It is not surprising that if you assume policy proposals are extended for over five times their original period, that they will produce almost five times the original impact. To understand this all that is required is to actually read and comprehend what is written. But Joe Romm is so full of bile for his President and so mad-crazy to save the planet from the evils of Climate Change and (mostly US) big business that he is blinded to that simple reality-check.

The fuller story is that even if all policies were fully enacted and extended to 2100, the impact on emissions would be far smaller than Joe Romm claims. That will be the subject of the next post.

Ladybird Book on Climate Change

A couple of weeks ago there was a big splash about the forthcoming Ladybird Book for adults on Climate Change. (Daily Mail, Guardian, Sun, Telegraph etc.) Given that it was inspired by HRH The Prince of Wales, who wrote the forward, it should sell well. Even better, having just received a copy in a format that harks back to the Ladybird Books I grew up with. That is on each double page words on the left and a high quality coloured picture filling the right hand page. Unlike, the previous adult Ladybird series, which was humorous, this is the first in a series that seeks to educate.

The final paragraph of the forward states:-

I hope this modest attempt to alert a global public to the “wolf at the door” will make some small contribution towards requisite action; action that must be urgently scaled up, and scaled up now.

The question is whether there is enough here to convince the undecided. Is this is founded on real science, then there should be a sufficient level of evidence to show

(a) there is a huge emerging problem with climate.

(b) that the problem is human caused.

(b) that there are a set of potential steps that can be taken to stop constrain this problem.

(c) that the cure is not worse than the disease.

(d) that sufficient numbers will take up the policy to meet the targets.

My approach is is to look at whether there is sufficient evidence to persuade a jury. Is there evidence that would convict humanity of the collective sin of destroying the planet for future generations? And is there evidence that to show that, through humanity collectively working for the common good, catastrophe can be averted and a better future can be bequeathed to those future generations? That presumes that there is sufficient quality of evidence that an impartial Judge would not throw the evidence out as hearsay.

Evidence for an Emerging Problem with Climate.

Page 8 on melting ice and rising sea levels starts with the reduced Arctic sea ice. The only quantifiable estimate of the climate change other than the temperature graph on page 6, in claiming at the end of the 2016 melt season the sea ice levels were two-thirds that of at the end of the end of the twentieth century.

Any jury would hear that there has only been satellite data of sea ice extent since 1979; that this was the end of a period known as the “sea ice years“; that the maximum winter ice extent in April was likely less in the eighteenth century than today; that ships log books suggest that general sea ice extent was the roughly the same one hundred and fifty years ago as today; and that in the Antarctic average sea ice extent increase has largely offset the Arctic decrease.

The rest about sea levels correctly state both that they have risen; that the reasons for the rise are a combination of warming seas and melting ice caps. It is also correct that flooding occurs in storm surges. But there is no quantification of the rise in sea levels (about 8-12 inches a century), nor of the lack of evidence of the predicted acceleration.

Page 10 on heatwaves, droughts, floods and storms states that they can cause disruption, economic damage and loss of life. there are also recent examples, and speculation about future trends. But no evidence of emerging trends, particularly increasing loss of life. This lack of evidence is because the evidence of the harms of extreme weather appear on the decrease. Indur Goklany has been a rich source of the counter-evidence over many years.

Page 12 begins

Threats to food and water supply, human health and national security, and the risk of humanitarian crises are all potentially increases by climate change.

The rest is just padding out this speculation.

Page 14 is on disappearing wildlife. One quote

The polar bear has come to symbolize the threats posed to wildlife by climate change….

You can probably find many images of starved dead polar bears to back this up. But the truth is that this creatures live by hunting, and as they get older slow down, so are no longer fast enough to catch seals, their main food source. Zoologist Susan Crockford has a blog detailing how polar bear numbers have increased in recent years, and far from being threatened the species is thriving.

The climate change problem is mostly human caused

The book details that emissions of greenhouse gas levels have gone up, and so have the levels of greenhouse gases. The only quantities is for CO2, the major greenhouse gas. (Page 20) There is simple diagram explaining how CO2 emissions impacts on atmospheric CO2 levels, before explaining the major sources of the net increase – fossil fuel emissions and clearing forests. There is no actual testing of the theory against the data. But Page 20 begins

The scientific evidence shows that dominant cause of the rapid warming of the Earth’s climate over the last half century has been the activities of people…

The relevant quote from UNIPCC AR5 WG1 SPM section D3 says something slightly differently.

It is extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas concentrations and other anthropogenic forcings together.

The extremely likely phrase is a Bayesian estimate. It is a belief that should be updated on the best available evidence. Lack of evidence, after much searching, suggests the original guess was wrong. Therefore true Bayesians would downgrade their certainties if they cannot refine the estimates over time. But this was written in 2013. Since the Carney Report of 1979 and the previous four IPCC reports of 1990 to 2007, there has been no refinement in the estimate of how much warming will eventually result from a doubling of CO2.

But how does the evidence stack up? On page 6 there is a chart of global surface temperature anomalies. That increase in temperatures can be tested against the doubling effect of CO2. Since around the turn of century the rate of rise in CO2 emissions and atmospheric CO2 levels has accelerated. But global warming stopped  for over a decade until 2014, only to restart due to a natural phenomena. Comparing the actual data to the theory, fails to support the strong beliefs that GHG emissions are the dominant cause of recent warming. 

Policy to contain the problem

Page 34 go into the benefits of containing warming to 1.5C. Given that the central estimate from the climate community since 1979 has been that a doubling of CO2 will lead to and eventual rise in average temperature of 3C, a rise in CO2 levels from the pre-industrial levels of 280ppm to 400ppm reached in 2015 would give 1.544C of warming. With other greenhouse gases it should be nearer to 2C of warming. Either it is way too late (and the warming is lurking like the Loch Ness monster is the dark and murky depths) or the central estimate is exaggerated. So the picture of three young people holding a banner with 1.5 to stay alive is of the doomed who we can do nothing about, or false alarmism.

Page 36 has a nice graphic adopted from the IPCC Synthesis Report of 2014, showing the liquid dripping through an egg-timer. It shows the estimate that 2000 billion tonnes of CO2 have been emitted so far, 1000 billion tonnes can be emitted before the 2 C of warming is breached. This was from a presentation to summarize the IPCC AR5 Synthesis Report of 2014. Slide 33 of 35.

Problem is that this was the data up to 2011, not five years later to 2016; it was for GHG emissions in billions of tonnes of CO2 equivalents; and the 40 billions tonnes of CO2 emissions should be around 52-55 billion tonnes CO2e GHG emissions. See for instance the EU Commission’s EDGAR figures, estimating 54GtCO2e in 2012 and 51GtCO2e in 2010 (against the IPCCs 49 GtCO2e). So the revised figure is about 750GtCO2e of emissions before this catestrophic figure is breached. The Ladybird book does not have references, to keep things simple, but should at least properly reflect the updated numbers. The IPCC stretched the numbers in 2014 in order to keep the show on the road to such extent that they fall apart on even a cursory examination. The worst part is at the very top of the egg-timer, coloured scarlett is “Coal, oil and gas reserves that cannot be used“. These are spread across the globe. Most notably the biggest reserves are in China, USA, Russia, Canada, Australia, Middle East and Venezuela, with the rest of the World have a substantial share of the rest.

The cure is worse than the disease

For the rest of the book to suggest European solutions like recycling, eating less red meat, turning down the heating to 17C and more organic farming, the authors write about making very marginal differences to emissions in a few countries with a small minority of global emissions. Most of those reserves will not be left in the ground no matter how much the first in line to the Throne gets hot under the collar. The global emissions will keep on increasing from non-policy countries with over 80% of the global population, two-thirds of global emissions and nearly 100% of the world’s poorest people. Below is a breakdown of those countries.

These countries collectively produced 35000 MtCOe in 2012, or 35 GtCO2e. That will increase well into the future short of inventing a safe nuclear reactor the size weight and cost of a washing machine. Now compare to the global emissions pathways to stop the 1.5C  or 2C of warming prepared by the UNFCCC for the 2015 Paris talks.

 

The combined impact of all the vague policy proposals do not stop global emissions from rising. It is the non-policy developing countries that make the real difference between policy proposals and the modelled warming pathways. If those countries do not keep using fossil fuels at increasing rates, then they deprive billions of people of increasing living standards for themselves and their children. Yet this must happen very quickly for the mythical 2C of warming not to be breached. So in the UK we just keep on telling people not to waste so much food, buy organic, ride a bike and put on a jumper.

There is no strong evidence would convict humanity of the collective sin of destroying the planet for future generations. Nor is there evidence that to show that a better future can be bequeathed to those future generations when the policies would destroy the economic future of the vast majority. The book neatly encapsulates how blinkered are the climate alarmists to both the real-world evidence and the wider moral policy perspectives.

Carbon Capture and Storage Loses another £100m but saves up to £10bn

Last week the National Audit Office published a report Carbon Capture and Storage: the second competition for government support. The main headline was

“The Department has now tried twice to kick start CCS in the UK, but there are still no examples of the technology working. There are undoubtedly challenges in getting CCS established, but the Department faced an uphill battle as a result of the way it ran the latest competition. Not being clear with HM Treasury about what the budget is from the start would hamper any project, and caused particular problems in this case where the upfront costs are likely to be high. The Department must learn lessons from this experience if it is to stand any chance of ensuring the first CCS plants are built in the near future.”

Amyas Morse, head of the National Audit Office, 20 January 2017

Key elements

  • Two Projects in the Competition.
  • When project cancelled £100m had already been spent.
  • The first competition running from 2007 to 2011.
  • Full subsidy from the Treasury (i.e. Taxpayers) would have been £1 Billion
  • Over 15 years, subsidy from consumers would have been £3.9 Billion to £8.9 Billion
  • Would have captured 1Mt to 2 Mt of CO2 a year.
  • Consumer subsidy between £105 and £172 Mwh, on top of the current wholesale price of around £45 Mwh.

The BBC carried the story, correctly citing many of the costs, as did the Express, which stated

At the time it was cancelled, the competition had two preferred bidders: the White Rose consortium in North Yorkshire which planned to build a new coal plant with the technology, and Shell’s scheme in Peterhead, Aberdeenshire, to fit CCS to an existing gas plant operated by SSE.

The NAO report said the department initially estimated it would cost consumers – who would subsidise electricity from the schemes – between £2 billion and £6 billion over 15 years, but by 2015, this estimate had risen to as much as £8.9 billion.

The report found the Treasury was concerned over the costs to consumers, and that the competition was aiming to deliver CCS before it was cost-efficient to do so.

Joanne Nova points to a July 2015 post on the subject of CCS by Anton Lang. He stated

CCS artificially raises the costs of coal fired power in two ways

First, it raises the initial construction cost for any new large scale coal fired plant by around 60%.

Second, the CCS process is hugely energy intensive — consuming up to 40% of the electricity generated by the plant. So  the plant can only sell 60% of the actual power it produces.

As a (slightly manic) beancounter, I like to put the costs in context.

  1. How much would the cost have been if the Treasury had not pulled the plug per tonne of CO2 saved?
  2. What is the value of the subsidy be if China and India adopted the plan?

In the full NAO report (a 389kb pdf) Figure 6 gives details of the two schemes shortlisted in the competition.

It is the Peterhead scheme that would incur the lower subsidy of £105 Mwh. The £3.9 billion works out at an average 290 Mw production, or 76% of capacity over 15 years. It is cheaper due to adapting old plant. The disadvantage is that there is only 30 Mt of CO2 storage capacity in the area, so the area does not have the facility to develop much more unless further infrastructure development is made to pump the CO2 offshore into old oil wells.

The White Rose scheme has higher subsidy of £172 Mwh. The £8.9 billion works out at an average 394 Mw production, or 88% of capacity over 15 years. It is new plant, but has the advantage of 520 Mt of CO2 storage capacity in the area.

If we add in the £1bn subsidy without interest, over 15 years the cost per tonne of CO2 saved is about £264 (US$330, A$435) for the Peterhead project and £300 (US$374, A$490) for the White Rose project.

The NAO report in figure 12 that the subsidy could come down to £94 Mwh with scale.

Let us see what would be the cost if India and China adopted CCS for the current coal-fired power stations, but increasing capacity by 25% to cover the efficiency losses. Assume subsidy is just $100 Mwh.

According to Greenpeace (could be unreliable), China has about 900,000 MW of capacity. Add in 25% and assume 70% capacity, gives around $700bn a year subsidy. This is about 6% of current GDP.

From Wikipedia, India had 310 000 MW of capacity in 2015.  Add in 25% and assume 70% capacity, gives around $240bn a year subsidy. This is about 12% of current GDP.

I am sure that China and India will want to follow the UK’s lead. The only slight issue is finding a hole big enough. Maybe instead they could build some big greenhouses and grow tomatoes very rapidly.

Bernie Saunders demonstrates why he was not fit to be President

Senator Bernie Saunders of Vermont was for a while running a close second to Hillary Clinton in the Democrat Primaries. Had his extreme left views, advanced years and the fact that he is the junior Senator from the 49th most populous State, he might have stood a chance against a former First Lady and Secretary of State. But Senator Sanders’ recent questioning of Scott Pruitt shows why he is unfit for high office. Ron Clutz has transcribed more of the dialog, by I think two statements encapsulate this.

At 0.45

As you may know, some 97% of scientists who have written articles for peer-reviewed journals have concluded that climate change is real, it is caused by human activity, and it is already causing devastating problems in the US and around the world. Do you believe that climate change is caused by carbon emissions from human activity?

There is no 97% survey of scientists which conclude these things. As Ron Clutz observes the nearest to definite questions was Examining the Scientific Consensus on Climate Change – Doran and Zimmerman 2009, where the second question was

2. Do you think human activity is a significant contributing factor in changing mean global temperatures?

One could answer “yes” if you thought that 10% of the rise in the was due to land use changes, and the rest due to natural factors. It does not ask about fossil fuel emissions, and the question allows for belief in other factors other than human activity whether known or unknown. Neither does it ask if temperature rise is net harmful, with huge devastating impacts already evident.

There is also the Cook et. al survey of peer-reviewed academic papers that I looked after listening to a lecture Cook gave at Bristol University in late 2014. The survey just looked to the assumption that humans cause some warming, whether explicit or implied. Like the Doran and Zimmerman survey it is just hearsay. This Sen. Sanders presents as good evidence that there is already a clear catastrophic problem caused by changes in the climate. If there is real and overwhelming evidence, why does Sen. Sanders not refer to that instead of misrepresenting bogus opinion polls?

Senator Sanders then goes even further.  At 1.50

While you are not certain, the vast majority of scientists are telling us that if we do not get our act together and transform out energy system away from fossil fuel there is a real question as to the quality of the planet that we are going to be leaving our children and our grandchildren. So you are applying for a job as Administrator at the EPH to protect our environment. Overwhelming majority of scientists say we have to act boldly and your’re telling me that there needs to be more debate on this issue and that we should not be acting boldly.

Sanders now says a majority of scientists are telling us we must change our energy systems. Aside from the fact that only a very small minority of scientists have any sort of competency in the field of climate, (and there is evidence a lot of demonstrated incompetency within the small group e.g. here), they have no expertise in the economic or moral cases for policy. For policy the interpretation of the moral imperatives and the practical possibilities should be the realm of politicians. For those who sit on specialist committees, they should at least have their own developed views on the field.

Senator Bernie Saunders has taken some very dodgy opinion polls, grossly exaggerated the findings, and then ascribed statements to the climatologists that are far removed, and way beyond, any competencies they might have. As I see it, the role of President of the United States, as a leader, is to critically interpret what they are given in order to make decisions for the nation. That is the exact opposite of what Sanders did last week.

Trump is wrong on China Global Warming Hoax but right on the policy consequences

Summary

  • Donald Trump’s famous tweet that Global Warming is a Chinese Hoax is false, but the policy implications are correct.

  • Total proposed climate policies under the Paris Agreement will not stop global emissions rising, but the policy aim is to have global emissions falling rapidly after 2020.

  • The Rio Declaration 1992 exempted developing countries from a primary obligation to constrain, let alone reduce, emissions. 

  • By 2012 the exempted countries accounted for 64% of global emissions and over 100% of the global emissions growth since 1990.

  • The exempted, countries will collectively have emissions rising for decades to come.

  • The most efficient policy is a carbon tax, applied globally. But even this is highly inefficient, only working by making fossil fuel use unaffordable to all but the very rich. That is morally unacceptable in developed countries, whilst would stop developing countries developing, likely leading to civil wars.

  • Actual climate mitigation policies are less efficient and more costly than a carbon tax.

  • Pursuing mitigation policies in just the developed countries harms the poor disproportionately and harms manufacturing. Such policies may not even reduce global emissions.

  • Even if catastrophic global warming is true, the policy reality is the same as if it were a hoax. In either case they are net harmful to the policy countries.

  • Like with utterly ineffective drugs that harm the patient, the rational response to climate mitigation policies is to ban them.

 

 

President-elect Donald Trump infamously claimed on Twitter

The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive.

I believe that statement to be totally false. The Chinese had nothing (or essentially nothing) to do with the climate alarmism that the Western intelligentsia (especially in the Anglosphere) seem to religiously accept as a series of a priori truths. But the policy implications of believing such a false position are pretty much the same for a policy-maker that (a) accepts as truth catastrophic global warming hypothesis, (b) puts their country first (but still values highly people in other countries, with an emphasis on the poor and the oppressed) (c) but understands the realities of global policy-making, along with the full economic impact of mitigation policy.

The Realities of Actual Mitigation Policy

The hypothesis is the basic form is that global human greenhouse gas emissions (mostly CO2) are resulting in rising greenhouse gas levels. This is forecast to cause large increases in global average temperatures, which in turn, many believe, will be catastrophic to the climate system. The major policy is to reduce the global greenhouse gas emissions to near zero.
The UNIPCC AR5 Synthesis Report, Summary for Policymakers 2014 tried to the maths very simple. They only looked at CO2 for the ballpark figures. Using the central assumption of a doubling of CO2 gives 3 degrees of warming, then 2 degrees comes when CO2 levels hit 450ppm. At end of 2016 it levels were about 404ppm, and rising at over 2ppm per year. Only is some warming from other greenhouse gases, so we are well beyond the 420ppm. That gives maybe 15 years tops. Somehow though figures seem to have been stretched a bit to give more time, something I will look at in a later post.
The UNFCCC – the body that brings all the countries together to cut emissions to save the planet – had an all-out bash at COP21 Paris in December 2015. In the lead-up all countries (excluding the EU countries, who let the masters in Brussels take the lead) made submissions on how they would contribute towards saving the world, or at least make a start up to 2030. Many were so vague, it was difficult to decipher the “ambition”. This was done to appear like the countries were doing something substantial, when in fact the proposals were often so insubstantial, that targets could be achieved by doing nothing at all. The UNFCCC put all the INDC submissions together on a global emissions graph.

The graph is very simple. Before the INDCs, emissions were forecast to follow the thin dark orange arrow. With the INDCs, the thick light orange forecast is still tracking upwards in 2030. The least-cost 2C scenarios is the blue arrow. This is going down by 2020, and by 2030 is substantially lower than today. The graph gives a very clear message – the whole exercise is pretty much an expensive waste of time. 40,000 people attended the meeting at Le Bourget airport North of Paris, including the vast majority of World Leaders. Rather than be honest, they went through the usual format with a breakthrough at five past midnight. Then they sent the “experts” away to think up yet more scary scenarios to get better proposals in the future.

 

Little More Policy will be Forthcoming

If they actually read the 1992 Rio Declaration, like Robin Guenier did in October 2015, they would have found out why. In particular Guenier draws attention to this statement in the declaration.

“The extent to which developing country Parties will effectively implement their commitments under the Convention … will take fully into account that economic and social development and poverty eradication are the first and overriding priorities of the developing country Parties.” [My emphasis]

These non-Annex 1 developing countries have had phenomenal economic growth, with driven by rapid development of cheap energy from fossil fuels. Guenier quotes some CO2 emissions figures. Instead, I have used the broader estimates of greenhouse gas emissions from the European Commissions’ EDGAR database, grouping the figures into the Annex I countries (the rich OECD countries, like the USA, Japan, European Union, Canada, Australia etc.); the Annex I Transitional economies (basically the ex-Soviet bloc in Europe); International air and shipping; and the Non-Annex, rest of the world.


The figures are quite clear. The growth in emissions in 22 years was greater in the Non-Annex developing countries than the world as a whole. But this is just the developing countries starting to catch up. The breakdown of the Non-Annex developing county emissions is below.

This “developing” part of the world now has 84% of the global population, but in 2012 was just 64% of the greenhouse gas emissions. India and China each have more than 4 times the population of the USA, Africa 3.5 times and S&E Asia 3 times. Whilst in China emissions growth will peak soon, in India emissions growth is only recently taken off.  In S&E Asia and Africa emissions growth has yet to really take off. No matter what the USA and a few other developed countries do, it will not make a big difference to the long-term outlook for GHG emissions. Now compare the global emissions to the UNFCCC graph of INDCs of the target emissions reductions for 2030. The UNFCCC scale is in billions of tonnes, whilst the scale I use is in millions. The least cost 2C scenario is lower in 2040 that the total non-Annex countries in 2012. Even without emissions growth in the non-Annex countries, the Annex countries could cut emissions by 100% and still the 2C limit will be breached by the 84% who live in countries with no obligation to cut their emissions.
But maybe the USA should cut emissions anyway? After all it will not cost much, so these developing nations will be brought into line. I only recently realized how wrong this view was. Economics Prof Richard Tol it one of the World’s leading climate economists, who (unlike me) happens to believe in the moral case for cutting greenhouse gas emissions. In a recent paper, “The Structure of the Climate Debate”, Tol explained how a global carbon tax was theoretically the most efficient means to reduce global greenhouse gas emissions. Use regulation, or rationing, or subsidies of renewables, and it will be more expensive – less bang for your bucks. However, I objected. He seemed to be saying that the carbon tax necessary to cut global emissions worked out at less than the taxation on gasoline in Britain. At over $3 (a level that is similar in much of Europe) there are still quite high levels of fuel usage. I can still remember my high school economics teacher, in teaching about elasticity of demand, said that a good example of inelastic demand were the “sin” taxes on booze, alcohol, tobacco and petrol (gasoline). You could have quite high taxes without impacting on demand. Well, after a few exchanges at cliscep blog turns out Tol (in the more technical Tol 2013 paper) was recommending a $210 tCO2 tax to be imposed in 2020 globally, plus an escalator of 5.5% a year forever. It would eventually make fossil-fuelled energy use unaffordable to all but the Hollywood A-listers. I showed British readers in GBP would that would mean, but for the US readers $210tCO2 is about $1.83 per gallon of gasoline. There would be uproar if it was introduced, and people might get more fuel efficient cars. With the escalator that would rise to over $3 a gallon in 2030, $9 2050, $35 in 2075 and$132 a gallon in 2100. There would also be similar hikes in electricity from coal and gas. This might not be fast enough to achieve the reductions required by the UNFCCC, but would not be sustainable in a country with democratic elections every few years.

But actual climate mitigation policies, are far less effective that the carbon tax. This includes subsidies or loan guarantees to speculative and unsustainable businesses, or flash renewable technologies that fail to deliver,

The carbon tax might be harmful to the poor and middle classes in America, but think of what it would do to the living standards of the poorest half of the world. Countries where parents are hoping that their children might enjoy cheap energy for cooking, lighting or heating, would see those hopes dashed. For billions of people their children or grandchildren would never have a family car, or be able to travel by plane. If the Governments of India, China or Indonesia tried to impose such high and escalating taxes there could be economic collapse similar to that of Greece, and likely civil wars.

Should the Rich countries still do something?

So maybe the United States, and other rich countries, should still adopt policies regardless. After all, they should pay for the (alleged) harms that are leading to disaster. But if the proposers had any understanding of the real world, they would know that just as economic growth has been propelled by abundant supplies of cheap, available and reliable energy. In international trade what is “cheap” is a relative concept. In the nineteenth century steam power was very expensive compared to electricity today. But at this point in time, when developing countries are make power more available and driving their unit energy costs down. Steam power was much cheaper, and more available than water power, which in turn was cheaper than human or animal power. Yet implementing emissions reduction policies, the rich countries are driving those unit energy costs up just as developing countries have been driving unit energy costs down and making power more available. The USA and EU countries are generating a comparative disadvantage. But, as the developed nations tend to be more energy efficient, the net effect on global emissions may be to increase them, despite the policy countries decreasing theirs. That net effect is unlikely to be as large as any actual savings in the policy countries. What is more, the costs of policy will fall on the poor, and those areas of employment with high energy usage and that compete internationally.

An argument for climate mitigation is that it is to make small sacrifices now to save future generations from the much larger costs of future catastrophic climate change. That is only true if global emissions are cut significantly, at a cost lower than the actual harmful impacts that would have occurred without policy. As policy to cut emissions will makes very little difference to global emissions, then the sacrifices could be of a small benefit in non-policy countries, but be to the net disadvantage of future generations in the policy countries. The biggest burden of the costs of policy will fall on the poorer sections of society and manufacturing in the policy countries.

The Moral Case Against Climate Mitigatiom

If the medical profession insisted on patients taking drugs that did not work and had harmful side effects, then in litigious America they would be sued for all they had, and likely jailed. But when the climate alarmists, back by the liberal establishment, insist on policy that cannot work and causes substantial harms they are not held to account. Indeed, so pervasive are the beliefs in climate alarmism, it is an act of heresy to even question this false policy. Now the tables are turned.

The first thing that should be done with harmful drugs that cannot work is to ban them from sale. For an incoming President, the first thing to do with harmful and useless policies is to rescind them.

Friends of the Earth distorting the evidence for Fracking in the UK

Summary

Friends of the Earth have a webpage claiming to be “fracking facts”. The key points I make are.

  • The claims of dangers of fracking raise questions, that need to be answered before they can be considered credible.
  • The claim that fracking could affect house prices is totally unsupported.
  • The claim that shale gas will not significantly affect energy prices is based on out of date data. The British Geological Survey has shown that the potential of shale gas is huge. Friends of the Earth has played a major role in preventing that potential being realized.
  • FoE has consequently helped prevent shale gas from relieving the energy crisis brought upon by the Climate Change Act 2008.
  • Claims that pursuing shale gas in Britain will affect global emissions are pure fantasy. Also is a fantasy the belief that Britain is leading the way on emissions reductions. We ain’t leading if collectively the world is not following. The evidence shows clearly shows this.  

In the previous post I looked at how FoE blatantly mislead about an agreement they reached with the Advertising Standards Authority, which caused the unusual step of ASA Chief Executive Guy Parker issuing a strongly worded statement to defend the ASA’s integrity.

In this post I will look at FoE’s position on fracking, from Fracking definition? What does fracking mean? Read our fracking facts

I will look at various statements made (with FoE quotes in purple), showing how well they are supported by the evidence and/or providing alternative perspectives.

From the section What are the dangers of fracking?

Industry statistics from North America show that around 6% of fracking wells leak immediately.

Leaking wells lead to a risk of water contamination. Lord Smith, former chair of the Environment Agency, has said this is the biggest risk posed by fracking.

So it’s particularly concerning that the Government has now said it will allow fracking companies to drill through aquifers which provide household drinking water.

This raises some questions.

  • If leaks are a problem, with respect to fracking in the UK has this been risk assessed, with appropriate measures taken to prevent leaks?
  • Does that statistic of 6% allow for when there is natural leakage in the area of fracking leaking in the water supplies are venting into the atmosphere in the area where fracking is occurring? This was the case in the images of the flaming water faucet in the movie Gasland.
  • Have there been steps taken in the USA to reduce genuine leaks?
  • Has the proportion of wells leaking gas in the USA been increasing or decreasing?
  • Has the average amount of gas leaked been increasing or decreasing?
  • How when extracting gas from well below water aquifers, through a lined tube, that is both water-tight and gas-tight, is that gas (and fracking fluids) meant to leech into the water supply?

Then there is the statement without evidence.

Fracking could also affect house prices.

This was one of the issues FoE in its agreement with the ASA have the assurance not to repeat claims that fracking affects property prices, unless the evidence changes. Legally there might be cop-out where that assurance does not apply to claims made on its website. Literally, the statement is not untrue, just as the claim that a butterfly flapping its wings on the North Downs could lead to a typhoon in the South China Sea.

Would fracking bring down energy bills?

It’s very unlikely. Fracking company Cuadrilla has admitted that any impact on bills would be “basically insignificant”.

Claims that fracking would create a lot of jobs have also been overstated. According to Cuadrilla, each of its proposed 6-year projects in Lancashire that were recently rejected by the council would only have created 11 jobs.

The claim about Cuadrilla is sourced from an Independent article in June 2013.

“We’ve done an analysis and it’s a very small…at the most it’s a very small percentage…basically insignificant,” said Mark Linder, a public relations executive at Bell Pottinger who is also responsible for Cuadrilla’s corporate development.

The article later says

“According to Poyry, Lancashire shale gas production could also reduce the country’s wholesale gas and electricity prices by as much as 4 per cent between 2014 and 2035, which corresponds to an average saving of £810m/year,”

It is not surprising that shale gas developments in Lancashire alone will not have a significant impact on UK energy prices, especially if that is restricted to a few sites by one company. But over three years later the landscape has changed. The British Geological Survey has been publishing estimates of the quantities of shale gas (and oil) that exists beneath the ground.

The figures are at first hard to comprehend. Large number in units of measure that ordinary people (even people with some knowledge of the field) are unfamiliar are hard to comprehend, let alone put into some perspective. In my view, the figures need to be related to annual British consumption. Page 8 of the DECC UK Energy Statistics, 2015 & Q4 2015 estimates gas demand at 794 TWh in 2015.

The BGS uses tcf (tera cubic feet) for its’ estimates, which (like a domestic gas bill) can be converted from TWh. The 794 TWh is about 2.7 tcf. Not all shale gas is recoverable. In fact possibly only 10% of reserves is recoverable on existing technology, and depending on the quality of the deposits.

There are also shale oil deposits, measured by the BGS in both barrels and millions of tonnes. Refinery production (a rough estimate of consumption) was 63 millions of tonnes in 2015. I will again assume 10% recovery.

The biggest shock was published just a few weeks after the Independent article on 27th July 2013. The size of the Bowland shale was truly staggering. The central estimate is 1329 tcf, meaning enough to satisfy 49 years of current UK gas demand. Potentially it is more, due to the depth of deposits in many areas. No significant deposits of oil are thought to be present

On 23rd May 2014 BGS published the results for the Weald Basin, a large area in the South East of England. Whilst there were no significant deposits of gas, the central estimate of 591 million tonnes is enough to supply the UK for one year.

On 25 June 2014 the Welsh Government published the estimates for Wales. The main gas deposits are thought to be in Wrexham/Cheshire and in South Wales and estimated about 65 tcf, or just over two years of UK demand. (Strictly the Welsh estimate is somewhat below this, as Wrexham is on the Welsh border and Cheshire is an English county. )

On 23rd May 2014 BGS published the results for the Midland Valley of Scotland. The central estimate for shale gas was 80.3 tcf (3 years of UK demand) and for shale oil 800 million tonnes (15 months of refinery production).

Most recently on 13th October 2016, BGS published the results for the Jurassic shale of the Wessex area. Central estimate for shale oil was 149 million tonnes, equivalent to three months of UK refinery production.

In all, conservatively there is estimated to be sufficient gas to supply the UK for over 54 years and oil for two and half years. The impact on supply, and therefore the impact on jobs and (in the case of gas) on energy prices, demands on the ability of businesses to profitability develop these resources. As has happened in the USA, the impact on jobs is mostly dependent on the impact on prices, as low prices affect other industries. In the USA, industries that are sensitive to energy prices (or use gas as a raw material) have returned from overseas, boosting jobs. FoE has played no small part in delaying planning applications with spurious arguments, along with generating false fears that could have made regulations more onerous than if an objective assessment of the risks had been made.

Fracking can’t help any short term or medium term energy crisis.

Even if the industry was able to move ahead as fast as it wants, we wouldn’t see significant production until about 2025.

This is actually true and up to date. If it were not for the Climate Change Act along with eco-activists blocking every move to meet the real energy demands in the most affordable and efficient way possible, there would be no prospective energy crisis. In terms of shale gas meeting energy demands (and gas-fired power stations being built) FoE should claim some of the credit for preventing the rapid develop of cheap and reliable energy sources, and thus exacerbating fuel poverty.

Will fracking help us to tackle climate change?

Shale gas and shale oil are fossil fuels. They emit greenhouse gases. Avoiding the worst impacts of climate change means getting off fossil fuels as soon as possible.

Scientists agree that to stop dangerous climate change, 80% of fossil fuels that we know about need to stay in the ground.

Setting up a whole new fossil fuel industry is going in completely the wrong direction, if the UK is to do its fair share to stop climate change.

The hypothesis is that global emissions lead to higher levels of greenhouse gases. In respect of CO2 this is clear. But the evidence that accelerating rate of rise in CO2 levels has led to accelerating average global temperatures is strongly contradicted by real world data. There is no scientific consensus that contracts this conclusion. Further there is no proper scientific evidence to suggest that climate is changing for the worse, if you look at the actual data, like leading climate scientist Dr John Christy does in this lecture. But even if the catastrophic global warming hypothesis were true (despite the weight of real world data against it) global warming is global. Britain is currently emitting about 1.1% of global emissions. Even with all the recently discovered shale gas and oil deposits, under the UK is probably less than 1% of all estimated fossil fuel deposits. Keeping the fossil fuels under British soil in the ground will do nothing to change the global emissions situation.  Britain tried to lead the way with the Climate Change Act of 2008, in committing to reduce its emissions by 80% by 2050. The INDC submissions leading up to COP21 Paris in December 2015 clearly showed that the rest of the countries were collectively not following that lead. The UNFCCC produced a graph showing the difference of the vague policy proposals might make.  I have stuck on the approximate emissions pathway to which the UK is committed.

The FoE is basically objecting to fracking to keep up the appearance that the UK is “doing its bit” to save the world from catastrophic global warming. But in the real world, global warming ain’t happening, neither are the predicted catastrophes. Even if it were, whatever Britain does will make no difference. FoE attempting to deny future jobs growth and stop the alleviation of fuel poverty to maintain the fantasy that Britain is leading the way on climate change.

 

Isn’t it better to have our own gas rather than importing it?

…….

If we went all out for shale, our gas imports would stay at current levels as the North Sea supply declines – and imports could increase by 11%.

This claim, without any reference, is based likely based on the same out of date sources as below. If FoE and fellow-travellers kept out of the way with their erroneous then shale gas has a huge potential to cause imports to decline.
