Scientists Conclude Dire Climate Change Models Were Wrong, Now What?

February 7, 2022

Scientists Conclude Dire Climate Change Models Were Wrong, Now What?

Scientists admit they did not model clouds accurately and that they need a supercomputer 1000 times more powerful to accurately do that.

Climate Change Modeling Meets Limits of Science 

The Wall Street Journal reports Climate Scientists Encounter Limits of Computer Models, Bedeviling Policy.

That is a non-paywalled, free-to-read link courtesy of the WSJ.

It’s lengthy but an excellent read. I encourage everyone to take a look.

The dire predictions went out the window, seemingly unanimously. But there is plenty in the article for the fearmongers and the sceptics to both say “I told you so”.

Italic emphasis in the snips below is mine.

Introduction

For almost five years, an international consortium of scientists was chasing clouds, determined to solve a problem that bedeviled climate-change forecasts for a generation: How do these wisps of water vapor affect global warming?

They reworked 2.1 million lines of supercomputer code used to explore the future of climate change, adding more-intricate equations for clouds and hundreds of other improvements. They tested the equations, debugged them and tested again.

The scientists would find that even the best tools at hand can’t model climates with the sureness the world needs as rising temperatures impact almost every region.

Dire Forecasts Wrong

When they ran the updated simulation in 2018, the conclusion jolted them: Earth’s atmosphere was much more sensitive to greenhouse gases than decades of previous models had predicted, and future temperatures could be much higher than feared—perhaps even beyond hope of practical remedy.
