Bjorn Lomborg: Trump gutting EPA climate regs show UN Paris treaty is ‘a paper tiger’

USA Today – By Bjorn Lomborg

According to the International Energy Agency, the U.S. promised to cut more energy-related CO2 emissions than any country in the world from 2013 to 2025, under the Paris climate treaty.

The problem is that this promise never had much ground in reality.

The primary measure America offered to achieve the promised cuts was the Clean Power Plan, which required the U.S. power sector to reduce CO2 emissions.

Yet this plan, even if fully enacted, would have achieved just a third of the U.S. promises under the Paris Agreement. If it had remained in effect for the entire century, my peer-reviewed research using United Nations climate change models found that it would have reduced temperature rises by an absolutely trivial 0.023 Fahrenheit at the end of this century.

Without the Clean Power Plan, U.S. emissions will likely increase slightly.

The treaty is nothing but a paper tiger: Its only legal underpinning is that all nations submitted promises — but those promises do not need to be kept.

In truth, Trump’s action just exposes what we have known for a while: The Paris Agreement is not the way to solve global warming.

Even if every nation fulfilled everything promised — including Obama’s undertakings — it would get us nowhere near achieving the treaty’s much-hyped, unrealistic promise to keep temperature rises under 1.5 degrees Celsius.

The U.N. itself has estimated that even if every country lived up to every single promised carbon cut between 2016 and 2030, emissions would be cut by just one-hundredth of what is needed to keep temperature rises below 2 C.

My analysis, similar to findings by scientists at MIT, shows that even if these promises were extended for 70 more years, then they’d only reduce temperature rises about 0.3 degrees F by 2100.

Moreover, many poor nations signed up to the treaty largely because of a promise of $100 billion a year of “climate aid” from rich nations, starting from 2020. Over the past five years, rich countries have managed to come up with only a 10th of one year’s promise.

It is only a matter of time before taxpayers from wealthy nations balk at the bill waiting for them. That will make many developing countries back out of the whole process.

This climate approach rehashes a failed policy that wasted decades: From …
