🌧️ Correlation distances of precipitation gauges vary in both space and time! New work out in @agu.org's GRL, led by @alexayeo.bsky.social (with @lakeographer.bsky.social and me) examines precip correlation distances over the US. Check it out: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Maps of the US, showing trends in precipitation correlation distances over a 70-year observational record in each season. Summer correlation distances are decreasing.

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.

Super 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! 🎉

Impact of current and warmer climate conditions on snow cover loss in burned forests

Wildfires are causing earlier snowmelt across the western US, and this effect would be exacerbated with projected warmer winters.

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.

The U.S. Geological Survey (USGS) Vizlab has just released a new, interactive data visualization website about the USGS National Water Availability Assessment Report and Data Companion. Explore the data and the key findings of the assessment at water.usgs.gov/vizlab/water... #DataViz #rstats #USGS

Stylized illustration of the water cycle of the lower 48 United States, showing the fate of water that enters through precipitation. Most of the water returns to the atmosphere through evapotranspiration, but much of the water ends up in the Atlantic and Pacific Oceans, in Canada, or in the Gulf of Mexico through streamflow.

Map of water limitation in the lower 48 United States by watershed. Areas with relatively high water limitation are in the high plains, Texas, California, and the Mississippi Embayment hydrologic regions.

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.

Would you, or someone you know, like to channel something into thinking rigorously about how safe and electrified housing for everyone might also save the grid?

I'm hiring a postdoc! 1-2 years, remote ok, $75k/year. Focus: model scenarios on deep building efficiency & grid impacts

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... +...

Hydrology Paper of the Day @hydro-adrienne.bsky.social on how hydrological processes are affected by variability with respect to temperature changes that can exceed a future global warming target before declining to a threshold: infrastructure, glaciers, biogeography, and further research.

New commentary paper out this week with @gruberte.bsky.social and Sara Warix in WRR - we argue that temperature overshoot has consequences for regional hydrology and water resources that bear consideration. agupubs.onlinelibrary.wiley.com/doi/full/10....

Drawing of the water cycle in a landscape with and without temperature overshoot. Impacts include forest cover, glacial contributions, infrastructure, geomorphology, water use for carbon dioxide removal, groundwater depletion.

Excited about this one -- we've got a ton of great modeling work that tells us broadly what climate / energy transition might look like, but it's time to start looking closely at complexity. Here we talk about issues with the water system that are different if we see warming that's later reversed.

Not that this is a new or original thought but because these fires, like others, have harmed people I love and taken more of my history away: this (actually worse than this) is what net zero gets us. We need to go so much harder.

Under a very high emissions scenario, days with deep snow may disappear across the US except high mountains by the end of the century.

“We see places like New Hampshire turning into places like New Jersey, which is a bit hard to swallow," said @lizloveswinter.bsky.social at #AGU2024

Snow days set to disappear across much of the US

By the end of the century, the eastern and southern US may never see deep snow cover the ground, with consequences for water storage as well as for the life on and beneath the snow
