Atmospheric Rivers Shaped Greenland’s Ancient Ice - Eos

New simulations reveal how atmospheric rivers influenced Greenland’s ice sheet during the Last Interglacial—offering clues to future melt in a warming world.

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. Here’s the story of how we got here after 15 years. many authors but shout out @jfarmersalmanac.bsky.social

🚨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/...

Time series of standardized streamflow anomaly for the Ganga River from year 700 to 2020 (derived from a hydrological model and from the Monsoon Asia Drought Atlas built from tree rings). The plot shows mostly balanced wet (blue/green bars) and dry (brown bars) years until the 20th century, when the black moving-average line dips sharply after 1990. The 1991–2020 mean (blue horizontal line) is well below the range of previous 1,300 years. Orange dots mark major documented historical droughts, but the recent drying is clearly the most severe.

Observed changes in precipitation and temperature between 1951 and 2020. Spatial distribution of change in (A) annual precipitation (%) and (B) annual mean temperature (°C) between 1951 and 2020 based on the Sen’s slope calculation. Grids with statistically significant trends (P <= 0.05), based on the Mann–Kendall test, are highlighted with stippling. The Inset panels in (A) and (B) represent the interannual variability in precipitation anomaly (%) and temperature (°C) averaged
for the Ganga River Basin (blue boundary). The total change in average precipitation and temperature over the GRB during 1951−2020, estimated using the Sen’s slope, is statistically significant (P-value <= 0.05) based on the Mann–Kendall test.

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.

Extra carbon during the Last Glacial Maximum, for example, so I’d love to know how the two scenarios can be reconciled. Thanks in advance!

Such a cool study! I have a question: does the AMOC slowdown lead to an expansion of the carbon-rich Antarctic Bottom Water, therefore partially compensating the loss of North Atlantic absorption of anthropogenic CO2? Circulation reorganization has been proposed as a way for ocean to store (1/2)
