The thought police...NSF now canceling (aka archiving) its premier climate change research program 'cause Trump and the DOGE bros think it'll make climate change go away?

Good luck with that.

👏🏽 Congrats to INSTAAR alum Peter Clark for being elected to the National Academy of Sciences! He's a professor @osuceoas.bsky.social & specializes in glaciers, ice sheets, sea level, & paleoclimatology. His INSTAAR advisor was John Andrews. Nice 2016 video on Peter: www.youtube.com/watch?v=Tjve...

Long time coming but finally getting our Sierra Nevada work out into the world - discussion still open. More to come. egusphere.copernicus.org/preprints/20...
Deglaciation of the Sierra Nevada (USA) during Heinrich Event 1
Abstract. A polar jet stream (PJS) split by the Laurentide Ice Sheet (LIS) is a well-established feature of Ice-Age atmospheric circulation. California’s central Sierra Nevada Mountains (37–38° N) lie...

Applications close on Wednesday (the 19th)!

One field season in the (partially) buried mountains of SE Greenland is definitely on the cards. Just have to decide if it's a 300 meter core at red, blue or purple...

New paper by Francisca Núñez Ferreira that among other findings develops a method to use the sediments in esker deposits to inform on the subglacial effective pressure gradient and how it changed in space/time. We find that eskers largely form at the margin. onlinelibrary.wiley.com/doi/10.1002/...
Subglacial hydrology insights from eskers developed atop soft beds of the Laurentide ice sheet
A new method was developed for estimating aspects of the subglacial hydraulic system based on sediments deposited within Eskers. It shows negative basal effective pressure gradients and temporal vari....

Me: Sees paper, goes to update favourite figure
Software: "You're gonna need a bigger x axis."
Global and regional temperature change over the past 4.5 million years
The global temperature record of the past 4.5 million years is consistent with changes in the carbon cycle.

A new paper by PhD student Andy Jones. One of those pandemic papers that finally made its way to print. Included zoom calls to teach wet chemistry and multiple hours of FaceTiming during HF and perchloric dissolutions and coordinated lab interchanges.
