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

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...

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

We (@chrisroadmap, Yi Qin, Karl Taylor, and I) computed updated aerosol effective radiative forcings and their many sub-components in CMIP5/6.

Life update: last month I started a postdoc at LLNL focused on using climate model projections to inform infrastructure planning. My heart will always be with forams but I’m excited for this new opportunity!

Scientific success often depends on having the creativity to find simple approximation that permit progress on important outstanding problems. What are the research questions where a creative person can make substantial headway by adopting simple approaches? (1/2)
