Point of no return: a hellish ‘hothouse Earth’ getting closer, scientists say Continued global heating could set irreversible course by triggering climate tipping points, but most people unaware

The Guardian just published a story on our paper "The Risk of a Hothouse Earth Trajectory" regarding a potential point of no return. You can read it for free here: www.theguardian.com/environment/...

Concerned about the Point of No Return? Today we published a paper on the risk of a hothouse Earth trajectory. You can read it here: authors.elsevier.com/c/1mbW49C~Iu...

The 2025 state of the climate report: a planet on the brink We are hurtling toward climate chaos. The planet's vital signs are flashing red. The consequences of human-driven alterations of the climate are no longer

In our Climate Report my coauthors and I say: We are hurtling toward climate chaos. The planet's vital signs are flashing red. Consequences of human-driven alterations of the climate are no longer future threats but are here now. Read report here doi.org/10.1093/bios...

SETTING: SOMETIME IN THE FUTURE: We were hurtling towards climate chaos which ended up really hurting the economy. More info here: doi.org/10.1093/bios...

Scientists Denounce Trump Administration’s Climate Report

Thanks to @andrewdessler.com for leading our group of 85 scientists to denounce the Trump administration's climate report which is packed full of misinformation. @michaelemann.bsky.social www.nytimes.com/2025/09/02/c...

I am pleased to be on the science team that wrote a very long response to to the Administration's DOE climate report which is full of errors. Thanks to @andrewdessler.com for leadership on our effort. See NPR story about our work: www.npr.org/2025/09/02/n...
