Whenever I post about climate, skeptical folks inevitable respond with this graph. So I decided to do something radical: actually read the underling scientific paper and ask the authors.
As it turns out, it actually says the opposite of what skeptics claim: https://www.theclimatebrink.com/p/climate-skeptics-have-new-favorite

Both Sam Altman (OpenAI) and Dario Amodei (Anthropic) have made some version of the argument that AI will give us the power to "fix the climate". I find this a deeply problematic position, as the challenges of mitigation are as much political as technological.

The carbon cycle has been close to equilibrium through the Holocene; we know this because we measure atmospheric CO2 concentrations in ice cores. But in the past few centuries CO2 has increased by 50%, and is now at the highest level in millions of years due to human emissions.
