As we alarmingly wrote "We are hurtling toward climate chaos" in our new State of the Climate Report which just came out. We may be on the path of a hothouse Earth trajectory as shown in this figure. Read the full report: doi.org/10.1093/bios...

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...
