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.
