IPCC moves goalposts from 2 to 1.5C — just a part of the PR plan to get more headlines

Pick a number, any number — the message is always the same. In 2018 the IPCC dropped the arbitrary 2C target to an arbitrary 1.5C target. The world hadn’t warmed fast enough, and worse, the new round of CMIP6 models were pushing their estimates of climate sensitivity up. But regardless, there are PR points to be made in every change. It’s an excuse for another round of “worse than we thought” press releases.

Commenter Joe teased:

Have the IPCC now become deniers? looks like we can only expect only .5 degrees C warming over the coming decades….

You’ve lost sight of the pea.

All the wild predictions are based on “Post Industrial” there has been about 0.95 deg since then, plus 0.5C brings us to the magic 1.5.

What you have to see is that all the $billions is about “preventing” an imperceptible and completely harmless 0.5 deg C change in temperature that might just come naturally anyway.

You are being duped. The aim frankly is to create an income stream via treaty that requires sovereign countries to levy […]
