Climategate : The greatest quote is from Kevin Trenberth

As Paul Matthews at IPCC Report and Anthony Watts at Wattsupwiththat are pointing out, 17th November marked the 5th Anniversary of Climategate1. Paul Matthews has his pick of the most significant quotes. But I believe he misses the most important. Kevin Trenberth to Micheal Mann on Mon, 12 Oct 2009 and copied to most of the leading academics2

The fact is that we can’t account for the lack of warming at the moment and it is a travesty that we can’t. The CERES data published in the August BAMS 09 supplement on 2008 shows there should be even more warming: but the data are surely wrong. Our observing system is inadequate. (emphasis mine)

The first sentence is the mostly widely quoted. It is an admission that we, the experts, cannot explain what is happening. The end of the quote is even more important. There is a clear divergence between the predictions from the climate models – the theoretical understanding of the world – and the real world data. Trenberth’s reaction is that the data is wrong, not the theory. His later excuse for continuing belief in the climate models was coined a few months later. The truth is lurking in the murky depths. As with the mythical Loch Ness Monster, the believers in climate catastrophism hold that the evidence will be found, but we are not able to access it yet. This has created a new branch of climatology – the excuses for the pause. At the time of writing there are 65 excuses and new cases are appearing at more than two a week.

Have 250.000 Spanish jobs been sacrificed for the folly of saving the planet?

Spain is one of the leading countries in Europe for Renewables. In 2013 output broke new records, with renewables accounting for 21.1% of Spanish electricity demand, with wind and hydroelectric power production increasing by 12% and 16%, respectively on 2012.

This is to the detriment of the Spanish economy for three financial reasons.

First is the huge amount now likely being spent on wind power subsidies. In 2013 output from wind farms was about 54GWh, or 12% higher than the 48.5GWh produced in 2012. Assuming an average subsidy of €54MWh (the rate for onshore wind turbines in the UK) that would be €2.9billion in subsidies.

Second, there is the huge amount now likely being spent on solar power. Spain is home to the massive Anadasol Solar Power Station. The three sections are expected to produce 495GWh per year, which at 38% of capacity seems a tad high. This will have a guaranteed price of €270 per megawatt. In the UK, the wholesale price is about £45 or €60 a megawatt. The excess cost (or subsidy) is therefore €210MWh, or €100million a year. At this rate, the total 8.2GWh produced by photovoltaics would have attracted a subsidy of €1.7bn in subsidies.

The combined estimated subsidy is worth €4.6bn is equivalent to 0.3% of GDP. Total subsidies are likely to be much more.

Third is the disastrous foray in solar panels lead to huge amounts of investments in solar schemes. In 2008 there were an estimated 30,000 jobs supported in the boom years. These jobs disappeared with the bust. With this sudden boom, caused by extremely generous subsidies, the quality of the panels was poor and overpriced. Many investors would not have got their money back even if the subsidies had remained. Now they will be saddled in debt, with no income. These borrowing were often state-backed. According to Bloomberg this fund was €24bn at the end of 2011. If some of this has to be written off, then there could be a material impact on deficit reduction plans, and thus the levels of unemployment. Government backing loss-making projects costs jobs.

This claim can be cross-checked. In the same Bloomberg article the Renewable Energy Producers Association (Asociación de productores de energías renovables or APPA) was quoted as saying that the renewables industry sustains about 110,000 Spanish jobs. In 2011 Verso Economics, a Kirkcaldy-based outfit, wrote a report about the effect of renewables jobs in Scotland and the impact on the wider UK. Whilst the report found that the jobs in renewables were largely neutral with Scotland – one job lost in the wider economy for each gained in renewables – in the wider UK economy for each job gained in Scottish renewables 3.7 jobs were lost in the wider UK economy. (report here, and reported at Caledonian Mercury, BBC and Scottish Sceptic) If this were replicated in Spain, the net impact of 110,000 jobs in renewables would be 400,000 jobs less jobs in the wider Spanish economy. Without renewables more than 250,000 people could be in work, or over 1% of the labor force.

Why I call Spain’s attempt to save the planet a folly, are the same reasons for calling Britain’s attempts a folly. Any emissions reductions in Europe will be more than offset by many times over from the emerging economies elsewhere. In reducing emissions, Spain will increase unemployment and reduce growth. But future generations will still bear over 80% of any consequences of warming than if no rich country did anything. In the current situation, I believe that a lot of Spanish people might object to their country being called “rich” anyway.

Spending Money on Foreign Aid instead of Renewables

On the Discussion at BishopHill, commentator Raff asked people whether the $1.7 trillion spent so far on renewables should have been spent on foreign aid instead. This is an extended version of my reply.

The money spent on renewables has been net harmful by any measure. It has not only failed to even dent global emissions growth, it will also fail even if the elusive global agreement is reached as the country targets do not stack up. So the people of the emissions-reducing countries will bear both the cost of those policies and practically all the costs of the unabated warming as well. The costs of those policies have been well above anything justified in the likes of the Stern Review. There are plenty of British examples at Bishop Hill of costs being higher than expected and (often) solutions being much less effective than planned from Wind, solar, CCS, power transmission, domestic energy saving etc. Consequences have been to create a new category of poverty and make our energy supplies less secure. In Spain the squandering of money has been proportionately greater and likely made a significant impact of the severity of the economic depression.1

The initial justification for foreign aid came out of the Harrod and Domar growth models. Lack of economic growth was due to lack of investment, and poor countries cannot get finance for that necessary investment. Foreign Aid, by bridging the “financing gap“, would create the desired rate of economic growth. William Easterly looked at 40 years of data in his 2002 book “The Elusive Quest for Growth“. Out of over 80 countries, he could find just one – Tunisia – where foreign aid conformed to the theory. That is where increased aid was followed by increased investment which was followed by increased growth. There were plenty examples of where countries received huge amounts of aid relative to GDP over decades and their economies shrank. Easterly graphically confirmed what the late Peter Bauer said over thirty years ago – “Official aid is more likely to retard development than to promote it.

In both constraining CO2 emissions and Foreign Aid the evidence shows that the pursuit of these policies is not just useless, but possibly net harmful. An analogy could be made with a doctor who continues to pursue courses of treatment when the evidence shows that the treatment not only does not work, but has known and harmful side effects. In medicine it is accepted that new treatments should be rigorously tested, and results challenged, before being applied. But a challenge to that doctor’s opinion would be a challenge to his expert authority and moral integrity. In constraining CO2 emissions and promoting foreign aid it is even more so.

The Climate Policy Issue Crystallized

There is a huge amount of nonsense made about how the rich industrialized countries need to cut carbon emissions to save the world from catastrophic global warming. Just about every climate activist group is gearing up to Paris 2015 where at last they feel that world agreement will be reach on restraining the growth of greenhouse gas emissions. Barak Obama will be pushing for a monumental deal in the dying days of his Presidency. There is a graphic that points out, whatever agreement is signed attempts to cut global emissions will be a monumental failure. It comes from the blandly named “Trends in global CO2 emissions: 2013 report” from the PBL Netherlands Environmental Assessment Agency. In the interactive presentation, there is a comparison between the industrialised countries in 1990 and 2012.


In over two decades the emissions of the industrialised countries have fallen slightly, almost entirely due to the large falls in emission in the ex-Warsaw Pact countries consequent on the collapse in the energy-inefficient communist system. In the countries formerly known as the “First World” the emissions have stayed roughly the same. It is the developing countries that account for more than 100% of the emissions increase since 1990. Two-thirds of the entire increase is accounted for by China where in less than a generation emissions quadrupled. Yet still China has half the emissions per capita of United States, Australia or Canada. It emissions growth will slow and stop in the next couple of decades, not because population will peak, or because of any agreement to stop emissions growth. China’s emissions will peak, like with other developed countries, as heavy industry shifts abroad and the country becomes more energy efficient. In the next 30-40 years India is likely to contribute more towards global emissions growth than China. But the “remaining developing countries” is the real elephant in the room. It includes 1050 million people in Africa (excluding South Africa); 185m in South America (excluding Brazil); 182m in Pakistan; 167m in Bangladesh, 98m in Philippines and 90m in Vietnam. The is over 2000 million people, or 30% of the global population that do not currently register on the global emissions scale, but by mid-century could have emissions equivalent to half of the 1990 global emissions. To the end of the century most of the global population increase will be in these countries. As half the countries of the world are in this group any attempt to undermine their potential economic growth through capping emissions would derail any chance of a global agreement.

Ivanpah 392MW Solar Plant a green energy failure even at the planning stage

The Hockey Schtick blog specializes in summarizing scientific papers that have a sceptical leaning. A couple of days ago it posted about the World’s largest solar energy plant applying for a $539million federal grant to help pay off a $1.5 billion federal loan. The Ivanpah solar electric generating plant is owned by Google and renewable energy giant NRG. Google can certainly afford to bear these loses. At the end of 2013 its accounts state that it had Cash, Cash Equivalents & Marketable Securities of $58,717million, $10,000million than the year before.

Technologically the Ivanpah plant sounds impressive. Problem is that in it’s first year of operation it produced one quarter of the projected electricity. As a minor consequence, it was projected to scorch 1,000 birds a year. Instead it is 28,000 in the first year. A three minute summary is at Fox News.

But even at the planning stage there was either no proper business plan presented, or at least no proper scrutiny like a bank would do when making a loan. 1065,000 MWh annually from a 392 MW nameplate is a planned output of 31% of capacity. Even accepting that figure, a $2bn investment with a 20 year payback (zero discount rate) is still nearly $100 MWh. A 10 year payback is much more reasonable. Add maintenance and operating costs easily gets to $200 MWh. A small utility company in Wisconsin buys in extra electricity for $30 MWh. So the planned cost was 6-7 times the wholesale price of electricity.

Maybe this was justified in saving the planet?

The AR4 synthesis report of 2007* said that peer-reviewed estimates of the social costs of carbon from averaged on 2005 $12 per tonne of CO2, but the range from 100 estimates is large (-$3 to $95/tCO2). If we take the bold assumption that the theoretic output of this plant would entirely replace the electricity from a typical coal-fired power station producing 900kg of CO2 per MWh, then the saving is $190t/CO2, or double the very top-end 2005 estimate, or 15 times the average estimate. For some reason, the Social Cost of Carbon is missing from the

Suppose the US was “really serious” about doing its bit to save the planet and tried to cut its CO2 emissions by 80%. In round figures, in 2013 that was 5 billion tonnes of CO2 equivalent (source CDIAC). Using similar schemes, it would cost $760bn a year or 5% of 2013 GDP of $16.8trn. Remember, that is if similar schemes are successful. The Ivanpah solar plant does not look like a success.

 

* For some reason, the Social Cost of Carbon is missing from the AR5 Synthesis Report published on November 1st. I would guess the reason that it has fallen out of favour is that the marginal abatement costs are much larger than the highest estimates, and the cost of doing nothing per tonne of CO2 are about zero.

BBC understates Cost of Climate Policy by 45 to 50 times

The UNIPCC has just finished a major meeting in Copenhagen to put finalize the wording of their AR5 Synthesis Report. BBC News Environment correspondent Matt McGrath said

The IPCC says that the cost of taking action to keep the rise in temperature under 2 degrees C over the next 76 years will cost about 0.06% of GDP every year.

Over the same period, world GDP is expected to grow at least 300%

The figure of 0.06% of GDP (strictly Gross World Product) seemed a bit low. So I looked up the source of this quote.

The Synthesis Report states on pages 116-117

Estimates of the aggregate economic costs of mitigation vary widely depending on methodologies and assumptions, but increase with the stringency of mitigation (high confidence). Scenarios in which all countries of the world begin mitigation immediately, in which there is a single global carbon price, and in which all key technologies are available, have been used as a cost-effective benchmark for estimating macroeconomic mitigation costs. (Figure 3.4). Under these assumptions, mitigation scenarios that are likely to limit warming to below 2 °C through the 21st century relative to pre-industrial levels entail losses in global consumption —not including benefits of reduced climate change (3.2) as well as co-benefits and adverse side-effects of mitigation (3.5, 4.3) — of 1% to 4% (median: 1.7%) in 2030, 2% to 6% (median: 3.4%) in 2050, and 3% to 11% (median: 4.8%) in 2100, relative to consumption in baseline scenarios that grows anywhere from 300% to more than 900% over the century. These numbers correspond to an annualized reduction of consumption growth by 0.04 to 0.14 (median: 0.06) percentage points over the century relative to annualized consumption growth in the baseline that is between 1.6% and 3% per year.

Matt McGarth (or a press officer) has wrongly assumed that 0.06% of GDP is the reduction in output, whereas the Synthesis Report talks about a reduction in growth rate. At any rate of growth, the impact of .06% reduction in growth rates will mean output in 2100 will be 4.8% lower. We can put a monetary impact on this through to 2090. The World Bank estimates global output was $74,910 billion in 2013. To keep the figures simple I will assume that 2014 will be $75,000 bn. The figures are below for 2090.

With 1.94% growth global output in 2090 will be $323,038bn, about $14,774bn less than if there was 2% growth. Cumulatively a 0.06% reduction in growth would be $369,901bn. But a cost of 0.06% each year of global output, with 2% growth is a mere $8,087bn. Misstatement of the UNIPCC’s position understates the cumulative cost by 45.7 times.

Similarly, with 2.94% growth global output in 2090 will be $678,356bn, about $30,716bn less than if there was 3% growth. Cumulatively a 0.06% reduction in growth would be $644,144bn. But a cost of 0.06% each year of global output, with 3% growth is a mere $13,107bn. Misstatement of the UNIPCC’s position understates the cumulative cost by 49.1 times.

The BBC or the UNIPCC needs to issue a correction. The UNIPCC have at last recognized that policy will effect economic growth. It is way too low, particularly for the high-policy countries who are put at an economic disadvantage relative to those countries without policies. Now they need to also look at the additional estimated costs of low carbon energy, along with the hidden costs of regulation and failed policies.

Britain’s Folly in Attempting to Save the World from Global Warming

Last week in the House of Lords1 Viscount Ridley asked Baroness Verma, a minister at the Department of Energy and Climate Change, about the hiatus in global warming. Lord Ridley asked Lady Verma

Would you give us the opinion of your scientific advisers as to when this hiatus is likely to end.

Lady Verma replied

It may have slowed down, but that is a good thing. It could well be that some of the measures we are taking today is helping that to occur.

I already commented at Bishop Hill – repeated by James Delingpole

From 1990 to 2013 global emissions increased by 61%. Of that increase, 67% was from China & India. This is not surprising as they were both growing fast from a low base, and combined contain nearly 40% of global population. The UK, with less than 1% of global population managed to decrease its emissions by 19%. In doing so, they managed to offset nearly 1.2% of the combined increase in China & India.

However this is not the full story, particularly with respect to understanding future emissions growth. Here I extend the analysis of the CDIAC data set2 to give a more comprehensive picture. CDIAC (Carbon Dioxide Information Analysis Centre) have estimates of CO2 emissions in tonnes of carbon equivalent for all countries from 1960 to 2013. These I have split out the countries of India, China and UK. The rest I have lumped into three groups – The major developed ACEJU countries3, the Ex-Warsaw Pact countries4 and ROW5 (Rest of the World). For emissions I have taken the baseline year of 1990, the latest year of 2013 and then forecast emissions for 20206.

The major developed economies have virtually unchanged, although, along with the UK the proportion of global emissions has fallen from 45% to 28% between 1990 and 2013 and are forecasted to fall further to 23% of global emissions even without aggressive emission reduction policies.

The collapse of communism meant the collective emissions of the Ex-Warsaw Pact countries fell by 44% between 1988 and 1999. That in 2020 emissions levels will still be around 20% lower, even though the economies will be far richer, is due to the inefficiencies of the Communist system.

China and India had most of the emissions growth between 1990 and 2013, there emissions growing by 300% and 250% respectively. That growth was equivalent to 16 times the UK emissions in 1990. By 2020 China and India’s emissions growth over 30 years is likely to have cancelled out the UK’s 30% reduction 78 times over. That forecast emissions increase from 1990 to 2020 is also a third larger than the combined 1990 emissions of the major rich countries.

Finally there is the ROW countries, nearly half the World’s population now live and where emissions increased by 130% between 1990 and 2013.

To put these figures in context, we need to look at population figures, which are available from the World Bank7.

The big CO2 emitters in 1990 were the First and Second World countries. Over two-thirds of global emissions were produced by a quarter of the population. Those same countries now produce 40% of global emissions and have 20% of the global population. The population has grown, but only by 10%. In some of the countries it is already falling. China’s population grew by 20%, India’s by 44% and the Rest of the World by 55%, giving a global population growth of 35%. Looking at CO2 emissions in tonnes per capita puts the CO2 emissions problem into perspective.

China started from an extremely low base in terms of emissions per capita. It is unlikely to exceed the rich world’s 1990 emissions per capita in the next 10 years. However, due to slower population growth and its current stage of development, it is unlikely to be the major source of emissions growth through to 2050. It is likely to be overtaken by India, who in turn will be overtaken by the rest of the world before the end of the century. Unless very cheap non-CO2 emitting sources of energy are developed, global emissions will continue to grow. That emissions growth will be the result of genuine economic growth that will see grinding poverty disappear from every country that embraces the modern world.

The UK with less than 1% of the world’s population will continue to have no impact at all despite all the hype of having the World’s “greenest” energy policies. Even if the scariest scenarios of Lord Stern’s nightmares are true, there is absolutely no reason to continue with policies that are pushing ever greater numbers into fuel poverty and jeopardizing security of energy supply. The future impacts will be just the same, but with current policy, Britons will meet that future poorer than without. The British Government is like a doctor that prescribes useless medicine in the knowledge that it has nasty side effects. Most would agree that a GP who did that to a patient should be struck off, even if it were one patient in hundreds.

For the people who still genuinely believe that increasing CO2 emissions will cause catastrophic climate change there are two causes of action. First is to find a plentiful source of non-polluting energy where the full costs are less than coal, but just as reliable. There is genuine pollution from coal in the form of smog, so everyone should be in support of this. Shale gas, then thorium nuclear reactors might be a ways forward in the next few decades. Second is to far more accurately predict the catastrophic consequences of global warming, so adaptation can be made at minimal cost and waste of resources. Every prediction of short term catastrophe (e.g. worsening hurricanes) or a worsening situation (e.g. accelerating sea level rise) has proved to be false, hence the reliance on noisy publicists and political activists that discourage learning from past mistakes.

Notes

  1. As reported by James Delingpole at Brietbart. Also reported at The Daily Mail, Bishop Hill, and Not a Lot of People Know That here and here.
  2. CDIAC is the Carbon Dioxide Information Analysis Centre. The 2014 Budget 1.0 contains estimates of CO2 emissions in tonnes of carbon equivalent for all countries from 1960 to 2013. I have converted the figures to tonnes of CO2.
  3. Australia, Canada, EU (the Western European 15, less UK), Japan and USA. This is most of what used to be called “First World”.
  4. This includes the former USSR countries, plus Eastern Europe. I have added in North Korea, Yugoslavia and Cuba.
  5. By definition this includes Central and South America, Africa, Middle East and South East Asia.
  6. Britain has committed to reduce its emissions by 30% of 1990 levels by 2020. China has pledged to “Reduce CO2 emissions per unit of GDP by 40–45% by 2020 compared to the 2005 level”. I assume 8% GDP growth and achieving a full 45% reduction, which is achievable. Similarly India has pledged to Reduce CO2 emissions per unit of GDP by 20–25% by 2020 compared to the 2005 level. Although it is unlikely to be achieved, based on emissions growth from 2005-2013, I have a assumed 7% GDP growth and achieving a minimum 20% reduction. For the other countries I have assumed half the emissions change from 1999-2013. This is likely to be an underestimate, as many other economies are growing emissions are a fast annual rate. For them this assumes a much reduced growth rate. Also many developed economies, particularly in Southern European showed sharp drops in emissions along with GDP in the credit crunch. They are now emerging, so should be expected to have higher emission growth rates.
  7. The 2020 population figures are assuming that each country’s population will change in the next seven years by the same number that it did in the previous seven. As world population growth in slowing, this might be a reasonable estimate. The result is a population increase of 550 million to 7,675 million.

São Paulo Drought – Climate Change is NOT the cause

Seca de São Paulo – Mudança Climática NÃO é a causa

The drought situation in São Paulo is critical. As of late October, the two principle reservoirs that serve the city were below 5% of capacity. Water pressures have been reduced to such an extent that people in the higher parts of the city are without water for most of the time. What is causing this?

The “Climate News Network” (website run by former Guardian & BBC journalists) they attribute this to deforestation and climate change1. They say

The unprecedented drought now affecting São Paulo, South America’s giant metropolis, is believed to be caused by the absence of the “flying rivers” − the vapour clouds from the Amazon that normally bring rain to the centre and south of Brazil.

Some Brazilian scientists say the absence of rain that has dried up rivers and reservoirs in central and southeast Brazil is not just a quirk of nature, but a change brought about by a combination of the continuing deforestation of the Amazon and global warming.

This combination, they say, is reducing the role of the Amazon rainforest as a giant “water pump”, releasing billions of litres of humidity from the trees into the air in the form of vapour.

Meteorologist Jose Marengo, a member of the Intergovernmental Panel on Climate Change, first coined the phrase “flying rivers” to describe these massive volumes of vapour that rise from the rainforest, travel west, and then − blocked by the Andes − turn south.

Satellite images from the Centre for Weather Forecasts and Climate Research of Brazil’s National Space Research Institute (INPE) clearly show that, during January and February this year, the flying rivers failed to arrive, unlike the previous five years.

This explanation of deforestation causing the drought does not hold water. The following is an account of why this drought explanation is flawed.

The “flying rivers” or “rios voadores” is being studied as a Petronas-sponsored long-term project at http://riosvoadores.com.br/english/. Project leader Gérard Moss explains the nature of “flying river” at 2:13.

The question is, where does the rain come from?

Most of the evaporation comes from the sea… The wind pushes this air over the Amazon Forest, a region where it rains quite a lot. The humid air eventually reaches the Andes, which force it south and that is what we are calling a “flying river

So the most important part of the evaporation is from the sea. A minor part comes from evaporation the Amazon Forest. Yet the Climate News Network is under the impression that all of the evaporation comes from the Amazon. The same is true of the Ecologist, which seems to have used the same material. What is even worse, both sources claim that 22% of the Amazon has been lost. That would mean that the total evaporation from the Amazon region will have reduced by less than this figure and the total moisture content of the “flying rivers” by less than 10%. Even so, there is nowhere provided any data that shows the rainfall in the area is reduced. If the hypothesis were true, then the rainfall near the mouth of the Amazon would be largely unchanged, but as the “flying river” goes south into NE Bolivia and Paraguay, and the Brazilian states of Rondönia, Mato Grosso do Sul, São Paulo, Parana and Santa Catarina, there should be evidence of diminishing rainfall. But despite a quite expensive project employing a number of people and two light aircraft (one a sea plane) there seems to be no effort to gather the data that might falsify the data. Further, project leader Gérard Moss (who is a pilot and engineer) does not seem open to falsification of the hypothesis.
Starting at 7:10 he says:-

My dream is that the Flying Rivers project, through studying (the flying rivers) behaviour, will scientifically prove the amount of rainfall in the south and the Amazon forest. My dream is that we will finally stop exchanging the forest for grazing land and plantations. ….. (T)he project’s greatest challenge is to prove to all us Brazilians, that it’s no longer worth felling one single tree.

Gérard Moss is a pilot and engineer. He is the one who has the use of two aircraft. Further, since mid-2012, the project has been restricted to educational projects2. One such project gives a useful tool that monitors the prevailing wind trajectories. The latest one I downloaded and superimposed the wind direction of the “flying rivers” in think blue arrows.


It would seem that the prevailing easterly winds have shifted south coming ashore in arid Bahia and doing a short loop round to São Paulo, completely missing the Amazon.

Unfortunately, the only map prior to October is for 23/07/14. This gives a similar picture of prevailing winds completely missing the Amazon.


I have a simple hypothesis that can easily be contradicted by archived data held by the website. The cause of the current water shortage lies in January and February, with the failure of the normal summer rains. My hypothesis that this failure was due to similar wind patterns occurring in January and February as found on 27th October. This, naturally occurring, phenomena would have occurred at a similar time to the Gulf Stream shifting course – in the UK shifting north causing extreme storms in Southern England, with flooding in Somerset and the Thames Valley, and in the USA shifting south causing the extreme cold of the Polar Vortex.

There is, however, a further video by the BBC (in English) where Gérard Moss explains that half or more of the rainfall in São Paulo is from the Amazon, as opposed to the sea.


There are three potential sources of water vapour that could condense as rain in the city of São Paulo, but are not mentioned. First is sea evaporation that has not passed over the Amazon. Second is land evaporation from air currents that have not passed over the Amazon, like in the cases above. Third is evaporation from the “flying rivers” airflows after passing over the Amazon. There is up to 2,000 km between the end of the Amazon forest and São Paulo.

Summary

The current extreme drought in the city of São Paulo is not the result of Amazon deforestation for two reasons. First, the deforestation is insufficiently large to account for the drought levels. Second is that evidence points to a natural southerly shift in the current year in the easterly winds coming ashore in Brazil from near the Amazon delta to the much drier coast of Bahia.

But if the deforestation is not the cause of the drought, what are the likely causes? This will be the subject of a further post.

Notes

  1. Over at the BishopHill blog, commentator Entropic Man has started a discussion thread on the current drought in São Paulo, which he claims is due to deforestation and climate change. As the BishopHill blog is almost entirely given over to climate issues, the inference by Entropic Man is that human-caused climate change is responsible.
  2. The website explains (in Portuguese)

    From the mid-2012, the project is restricted to educational, awareness actions and counts with the collaboration of the CPTEC in providing the data provided on the links of the weather mapsan important tool that allows the general public to see and track the trajectories of the flying rivers.

The Global Warming Consensus Conundrum

It might be the case that power and money are trumping the truth in global warming. But that power and money is fortified by a belief in the catastrophic anthropogenic global warming hypothesis. This in turn is based on “everybody” who is “anybody” agreeing with everyone else who is “anybody” and claiming that those who question what “everybody” who is “anybody” accepts is a nobody. But the source of the knowledge that “everybody” who is “anybody” agrees with is nobody.

This is in response to the comment by Craig King:-

It is going to take a lot more than facts and evidence to stop this behemoth. Too many people have got too much invested in the CAGW construct for it to be stopped by the truth. Aye, theres the rub, money and power trumps the truth any day of the week.

Within the documentation (page 9 of the full report) is Figure SPM.3 | Climate-change adaptation as an iterative risk management process with multiple feedbacks. People and knowledge shape the process and its outcomes. [Figure 2-1]

This graphic implies that the UN has the ability to tell governments what to do. You all voted for that didn’t you?

Yes the UN minions have set themselves up as identifiers of risk, assessors of risk, establishers of decision-making criteria, and implementers decision and then they’ll monitor you compliance.

I am not sure that I entirely agree. The UNIPCC might have set themselves up as telling governments what to do, but they only partially heed what they claim in the chart, and governments even less so. For instance on “scoping“, the identification of risks and vulnerabilities is only partially followed through. In AR4 the UNIPCC scrapped around for every possible risk they could find, and then embellished them. They later admitted the Himalayan glaciers were fabricated, but there was nothing on similar fabrications for crop failures in Africa or for the collapse of the Amazon Rainforest. Nor was there an admission that claims of increasing hurricane activity were unsupported; or that the vanishing snows of Kilimanjaro were not from rising temperatures . The process of scoping should include categorizing risks according to magnitude, likelihood and the quality of the evidence. But no such critical evaluation takes place.

Implementation is a loop of

Implement Decision Monitor Review and Learn

In practice (with the UK as an example) implementation is accompanied by an enforcing agency whose monitoring consists of justifying the policy, with no independent audits of the success of the policy, nor identifying any adverse consequences. As a result the reviews to not learn from mistakes, nor how to improve the quality of policy, nor how to take into account new evidence, nor to consider the increasing evidence that the optimal policy is to do nothing.
