New paper led by recent Auburn graduate Sarah Barney and w/ @richardsvachula.bsky.social , where we used charcoal to assess the type of vegetation burnt 🔥 in South China during the late Miocene when C4 grasses expanded (funded by @us-sciod.bsky.social; formerly USSSP) doi.org/10.1029/2025...

Assessing Fuel Type Changes in the Late Miocene C4 Grass Expansion Through Sedimentary Charcoal Analysis of the South China Sea Ocean Drilling Program Site 1146

The Fire Hypothesis posits fire catalyzed the late Miocene C4 grassland expansion but few proxy studies resolved both fuel type and fire South China Sea (Ocean Drilling Program Site 1146) sedimen...

Excited to share my paper is out in Geophysical Research Letters! 🚨 Neural networks --> Equation discovery! 🚨 Find our paper here: doi.org/10.1029/2026... This work is an example of hybrid modeling, where machine learning enhances a component of a larger model. ... 1/4

Just in: UCAR has filed a lawsuit against NSF, the Commerce Dept, NOAA, and OMB to prevent the dismantling of NCAR, alleging "violations of the Constitution and the Administrative Procedure Act."

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

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! 🌊 link.springer.com/epdf/10.1007...

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! Website: pastglobalchanges.org/science/wg/2...

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!! www.sciencedirect.com/science/arti...

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 …

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 dx.doi.org/10.1029/2024...

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...

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.
