High temperatures and low precipitation in the American West last winter led to record-low snowpack. A study finds that such a snow drought is 4.4 times more likely in the current climate than it would have been in the pre-industrial climate. In PNAS: https://ow.ly/LKKh50ZtquX
New paper out in @pnas.org: this year’s western U.S. snow conditions were pretty dismal, but to what extent was this snow drought due to climate change? Paper: www.pnas.org/doi/10.1073/... (with Marianne Cowherd, Stefan Rahimi, Yuhong Ye) Thread:👇

Beyond Denial: How Oil Execs Shaped a Landmark Climate Study
BP sponsored an elite Princeton research center to address the climate problem without getting off fossil fuels. Its key work, a paper known as “Wedges,” guided climate discourse for a generation.

Hydrology Paper of the Day @hydro-adrienne.bsky.social on how water flow in a river is related to the amount of water shared between water right holders: relating hydrograph standard deviation of timing to a spatial geography of processes; correlations with Q; and a case study of the Rio Grande.
Adrienne Marshall@hydro-adrienne.bsky.social · 3mo agoNew paper out today in Nature Water! We examine how changes in the *width* of the streamflow hydrograph affect water allocation among junior and senior water users. Paper: www.nature.com/articles/s44...

Hydrology Paper of the Day @akoshkin.bsky.social @hydro-adrienne.bsky.social on how wildfires affected by climate change remove trees and also affect snowpack hydroclimatology: changes in annual snow disappearance date related to location, radiation, temperature, elevation, and time since burn.
Adrienne Marshall@hydro-adrienne.bsky.social · 11mo agoSuper excited to have this work out showing how snowmelt timing changes in burned forests across the west. Big congrats to @akoshkin.bsky.social on leading this! 🎉

Yesterday was the darkest day of my professional life so far. Many of NSF’s best and brightest people fired indiscriminately. The terms of their firing cruel. My colleagues matter, they are valued and they make a difference. I have no words. www.npr.org/2025/02/18/n...
National Science Foundation fires roughly 10% of its workforce
NSF fired 168 employees, leaving the agency less equipped to fund a wide range of scientific research.

Appreciate the opportunity to chat w/ @nytimes.com about how we can build smarter (and to code!!) after these wildfires. Suspending wildfire building codes only kicks the can down the road and invites another disaster. Hardened homes and defensible space for the win. www.nytimes.com/interactive/...
How L.A.'s Housing Development Plays a Role in Wildfire Risk
Fierce winds and months of drought set the conditions for the catastrophic wildfires in Los Angeles, but the growth of housing in fire-prone areas also played a major role.

How far back in time can you go to find the earliest climate science related warning re what we now call GHG emissions & their effect on climate change? It turns out, it's a very long time. The earliest I know of relates to the work of Eunice Newton Foote. 🧪🔌💡 www.climate.gov/news-feature... +...
