We just published a paper on climate sensitivity in #CMIP6 models: agupubs.onlinelibrary.wiley.… Figured it was time for my first twitter thread!

Causes of Higher Climate Sensitivity in CMIP6 Models

Climate sensitivity is larger on average in CMIP6 than in CMIP5 due mostly to a stronger positive low cloud feedback This is due to greater reductions in low cloud cover and weaker increases in low...

Livermore broke the daily maximum temperature record of 109° set in 1905. The new record for today, July 6th is now 111°.

Shout out to my co-authors Tim Myers, @D_McCoy_Atmos, @pochedley, Peter Caldwell, @PauloCeppi, Steve Klein, and Karl Taylor, without whom this would not have been possible. And of course to the RGMA program at @doescience for funding this work thru PCMDI at @LLNL

Not sure what this "pattern effect" thing that you've heard about means? Here's a quick read we put together (led by Maria Rugenstein/not on X, @mzelinka @PauloCeppi @Tim_AndrewsUK).
AGU's Eos@AGU_Eos31 Oct 2023
Improving our understanding of the “pattern effect” is a promising avenue to reduce uncertainty in estimates of climate sensitivity, a grand challenge in climate science, scientists write. eos.org/features/patterns-of…

❌ No, the word “phat” did not originate as an acronym for the phrase “Pretty Hot And Tempting.” snopes.com/fact-check/chewin…

It's our birthday! 🎉 In 1952, #LLNL was founded as a “new ideas” lab, pursuing audacious ideas and pushing the extremes. Today, our site has evolved but our commitment to our mission continues. Cheers to 70 years of making the impossible possible! #LLNL70th @ENERGY @NNSANews
