Is The United Nations The Greatest Enemy Of The Climate?

October 9, 2018

In its latest report on climate change, October 2018, UN now claims that climate warming caused by human activities is reversible. That absurd claim is much more damaging than Trump clownish positions on climate change and coal. And yet, contrarily to what UN scientists claim, overshooting the target, and then cooling off will probably not work, because of nonlinear effects. Once ice is gone, ice doesn’t come back easily.

Climate change, so far, has been linear: every year a bit warmer, a bit more CO2. That’s not the main problem. The main problem is that the planet could switch to a Jurassic regime.

The UN scientific report on climate change claims that, in the likelihood that governments fail to avert 1.5 degree Centigrade (2.7 degrees F for US primitives) of warming, another scenario is possible: The world could overshoot that target, heat up by more than 2 C (3.6 F) degrees, and then through a combination of lowering emissions and deploying carbon capture technology, bring the temperature back down below the 1.5C (2.7F) degree threshold.

In that utopical UN climate round trip scenario, some damage would be irreversible, the report claims. (yes, sure, *some*). All coral reefs would die. However, the sea ice that would disappear in the hotter scenario would return once temperatures had cooled off, bleats the UN… The ice will return? This is unproven and most certainly FALSE: once the albedo of the Arctic is changed, it won’t come back, and the Arctic ocean will heat up. The Arctic ocean already contains enough heat 50 meters below its surface, to melt said frozen surface completely.


The global temperature graph up to 2018. One seems to see an overall acceleration, a nonlinearity, an exponential drawing itself… Exponentiation is the typical nonlinearity.

For governments, the idea of overshooting the target but then coming back to it is attractive because then they don’t have to make such rapid changes,” Dr. Shindell, a climate scientist at Duke University and an author of the report, said. “But it has a lot of disadvantages.” Yeah: like it won’t happen. Cheap enough CO2 capture, for example, doesn’t exist.  

Says NYT:

A landmark report from the United Nations’ scientific panel on climate change paints a far more dire picture of the immediate consequences of climate change than previously thought and says that avoiding the damage requires transforming the world economy at a speed and scale that has “no documented historic precedent.”

The report, issued on Monday by the Intergovernmental Panel on Climate Change, a group of scientists convened by the United Nations to guide world leaders, describes a world of worsening food shortages and wildfires, and a mass die-off of coral reefs as soon as 2040 — a period well within the lifetime of much of the global population.

The report “is quite a shock, and quite concerning,” said Bill Hare, an author of previous I.P.C.C. reports and a physicist with Climate Analytics, a nonprofit organization. “We were not aware of this just a few years ago.” The report was the first to be commissioned by world leaders under the Paris agreement, the 2015 pact by nations to fight global warming.

The report was written and edited by 91 scientists from 40 countries who analyzed more than 6,000 scientific studies. The Paris agreement set out to make a big wishful thinking about preventing warming of more than two degrees centigrade (3.6 degrees Fahrenheit as US primitives have it) above preindustrial levels — long considered a threshold for the most severe social and economic damage from climate change. Heads of small island nations, hounded by rising sea levels, also asked scientists to examine the effects of 1.5 C (2.7 F) degrees of warming.

Absent aggressive action, many effects once expected only several decades in the future will arrive by 2040, and at the lower temperature, the report shows. “It’s telling us we need to reverse emissions trends and turn the world economy on a dime,” said Myles Allen, an Oxford University climate scientist and an author of the report.

To prevent 1.5 C (2.7 F) degrees of warming, the report said, greenhouse pollution must be reduced by 45 percent from 2010 levels by 2030, and 100 percent by 2050. It also found that, by 2050, use of coal as an electricity source would have to drop from nearly 40 percent today to between 1 and 7 percent. Renewable energy such as wind and solar, which make up about 20 percent of the electricity mix today, would have to increase to as much as 67 percent.

These requirements are not planned by most of the industrialized world. The report concluded that the greenhouse gas reduction pledges put forth under the Paris agreement will not be enough to avoid 2C (3.6 F) degrees of warming.

Despite the policy implications, which go against Trump’s climate skepticism stance, the United States delegation joined more than 180 countries on Saturday in accepting the report’s summary for policymakers. A State Department statement said that “acceptance of this report by the panel does not imply endorsement by the United States of the specific findings or underlying contents of the report… We reiterate that the United States intends to withdraw from the Paris agreement at the earliest opportunity absent the identification of terms that are better for the American people,” the statement said. The Trump position has been that a number of provisions of the Paris Accord, such as a 100 billion fund to help the Third World, are unacceptable.  However the fact remains that, after Obama’s giant fracking effort, major US states have the most ambitious sustainable energy programs (especially mighty California).

The UN scientific report emphasizes the necessity of a tax on carbon dioxide emissions. “A price on carbon is central to prompt mitigation,” the report concludes. It estimates that to be effective, such a price would have to range from $135 to $5,500 per ton of carbon dioxide pollution in 2030, and from $690 to $27,000 per ton by 2100. 

The cost of fossil-fuel emissions rose to its highest level in more than a decade in Europe, in August 2018, surpassing 20 euros a ton ($23) and adding to the cost of electricity across the continent.

Carbon emission permits have more than quadrupled from less than 5 euros since the middle of 2017 after European Union governments agreed to cut away a surplus that had depressed prices of the CO2 permit market since the financial crisis that started in 2008. Utilities and industrial polluters need the certificates to cover greenhouse gas emissions they produce.

By comparison, in fossil fuel happy USA, under the Obama administration, government economists estimated that an appropriate price on carbon would be in the range of $50 per ton (but they did nothing, as usual in Obama’s administration). Under the Trump administration, that figure was lowered to a ridiculous $7 per ton. Those with Trump Derangement Syndrome will say: we told you so. However, in the area of climate change, Trump is mostly wind: he used to be a climate alarmist (not as bad as yours truly). Now Trump has skeptic, because it brings him votes (but in truth he does nothing, same as Obama).

Whereas what the UN is doing by claiming climate change can be reversed, (with sci-fi technology) is diabolical… and will hogtie leaders such as… Trump: how can one justify thorough changes in all of society, while being told, by the UN it’s all for nothing, it’s not necessary? 

What is going on? A form of ubiquitous corruption: scientists who authored the UN report are all, directly or indirectly, government employees. They want to please their employers, so that they can be paid, be influential, and honored. Those employers themselves are trying to please their plutocratic masters (and future employers). So they engineered a completely unrealistic wishful loophole, resting on non-existing technology (efficient, cheap, mass, planetary sized CO2 capture).

9 years ago, I pointed out the UN ignored the potential for a nonlinear climate change catastrophe:

Now the UN has done even worse: it claims that climate disasters are coming, but won’t cost that much (1% GDP for 1C of warming), & they are reversible. BS!
