Trump Administration Readies Plans to Dismantle Renowned Science Lab

This should be the biggest weather and climate news on your radar today.

You can send an email today to say why dismantling NCAR is a bad idea for everyone: NSF_NCAR@nsf.gov

#ClimateModels can't match #LongTerm observed changes in the #TropicalPacific zonal #SSTGradient, implying model responses to growing radiative forcing from #GHG is diverging. #ClimateChange #CMIP6 @hannah-byrne.bsky.social @lamont.columbia.edu @climate.columbia.edu

This work also wouldn't be possible without the resources and simulations provided by @ncar-cgd.bsky.social !!

Backstory: This work started back when @aakashsane.bsky.social and I were grad students in @baylorfk.bsky.social 's lab. Most of the discussions during lab meetings were way over my head, but this paper shows that I did get something out of all these meetings in the end!

A more detailed description of our approach can be found in another paper Aakash wrote

This work was inspired by @aakashsane.bsky.social's PhD work on the Narragansett Bay. Here's a 2min video on one of his works made by @baylorfk.bsky.social

Excited to share our new paper (w/ @aakashsane.bsky.social @baylorfk.bsky.social) where we used the CESM-LME and information theory to understand Pacific decadal variability! 🌊

Have you been following @profmattjones.bsky.social and @raindrop-herder.bsky.social who are sharing insights into the work of the PAGES 2k Network working group?
Drop them a follow to see what else they have in store during the #21daysof2k!

Orbital forcing of the eastern equatorial Pacific thermocline in the late Pleistocene Eastern equatorial Pacific thermocline depth is an important component of the tropical Pacific's coupled ocean-atmosphere system and varies across El …

Check out @cpallone.bsky.social et al. (2025) in QSR, which reconstructs eastern equatorial Pacific thermocline response to orbital forcing. Exciting to see research I contributed to for my undergrad thesis now published!!

The Influence of Carbon Dioxide and Precession on Western North American Hydroclimate and Pacific Sea Surface Temperature During the Holocene A network of proxy records shows western North American hydroclimate and Pacific sea surface temperature co-evolved during the Holocene The western North America became wetter while the eastern e...

Excited to (finally) share my new paper on Pacific SST and western North America hydroclimate during the Holocene! TL;DR They are connected, CO2 and precession both affect hydroclimate. Thanks @xiaojingdu.bsky.social @meredithparish.bsky.social @baylorfk.bsky.social+others

Recipients of a U.S. Climate Science Fellowship Are Put on Unpaid Leave

Big up to @rdzombak.bsky.social for bringing eyes to this story. 🧪

So many people beyond my little cohort of fellows are impacted by slowdowns at NOAA. America is rapidly losing footing as a leader in climate science and we all are paying the cost.

Fundamentally unchanged northwestern African rainfall regimes across the Plio-Pleistocene transition The northern African summer monsoon was unaffected by global cooling at the end of the Pliocene 3 million years ago.

New Science Advances paper on Plio-Pleistocene northern African hydroclimate! Tl;dr the wet summer monsoon = summer insolation & the dry winter monsoon = global ice volume

Details of Tehreem Qureshi's poster, titled Characterizing the Unprecedented Co-Occurrence of 2023 Boreal Summer Heat Extremes in Central America, Western Europe, and Central Asia. It will be on Monday, December 9, 2024 from 1:40PM -5:30 PM at Hall B-C (Poster Hall).

Perhaps more excitingly, Tehreem Qureshi, a @lamontearth.bsky.social summer intern who worked with me, Yelin Jiang and Jason Smerdon, will present a poster at #AGU24! Come and learn about what she did this summer and will do for her senior thesis! P.S.: She's currently applying to grad school!

Details of my presentation, titled Decadally synchronous Pan-Pacific hydroclimate extremes over the last millennium. It will be on Thursday December 12, 2024 from 11:30-11:40 AM at 102 A-B (Convention Center).

Excited to present my work at #AGU24 on decadal-scale sychronous pan-Pacific hydroclimate extremes over the last millennium! Stop by and learn about what I've been up to lately at Lamont!
