NSF NCAR CGD scientists joined a Texas A&M workshop on high & ultra-high resolution Earth system modeling. As models sharpen from ~100 km to ~3 km, they can better capture regional detail & extremes but bring big scientific and computational challenges. Proud of our CGD scientists!

Little coverage of the two big new Nature papers using the Allan Hills blue ice, showing that CO2 may not have been the primary driver of the Mid-Pleistocene Transition. This is a super interesting debate about a fundamental process of the past climate, if you haven't covered it before.

Today, we published a study long in the making on how upper and subsurface tropical Pacific waters responded (and maybe will adjust) to warmer global climate.

🚨New work🚨 led by Ph.D. student Dipesh Chuphal (IIT Gandhinagar), shows that the recent drying of the Ganga River basin is unprecedented in 1,300 years—more severe than historical famines. This ~multidecadal drying appears forced, but many models do not capture it. ☔️ 🌧️ www.pnas.org/doi/10.1073/...

Unbelievable experience with the journal Palaeo3. Our manuscript was rejected because… they couldn’t find a second reviewer, and it had been in their system “too long” (7 weeks), according to the editor. In other words, just to preserve their review-speed metrics, they rejected our submission.

Earth scientists know a lot more about getting out of an ice age than going into one. We report an episode of AMOC slowdown at 115 thousand years ago that's likely astronomically forced (via sea-ice) and coincides with a delayed drawdown of atmospheric CO2 @natcomms.nature.com rdcu.be/eALD1
