Morning thoughts on bedrocks steps and steep edges in glacial valleys.
Luke Zoet@lzoet.bsky.social · yesterdayCheck out this new paper we have in @pnas.org ! It’s got some big findings about glacial erosion. Namely that quarrying is ~5x more efficient at eroding bedrock than abrasion and that power based erosion laws are the most appropriate for modeling erosion www.pnas.org/doi/10.1073/...
The Lower Basin could be hit hard: California, Arizona, and Nevada could be called on to cut their water use from the Colorado by 3 million acre-feet. This terrific @coloradosun.com article breaks it all down: coloradosun.com/2026/07/31/c...
Everything you need to know about the new federal report on the Colorado River's future
Federal agencies released the first of several highly anticipated reports that will outline how the river will be managed for years to come.

Climate.us@climate.us · 4w agoWhat is Climate.us? It’s a new independent, nonprofit climate information website with a simple goal: keep trusted climate science easy to find, easy to understand, and available to the public. Climate information is a public good. Climate.us is here to help protect it. Explore Climate.us 🌍️ 🧪
Luckily I have to do all kind of bureaucratic paperwork today, so no chance to go outside anyway.
University of Colorado Boulder (CU Boulder)@colorado.edu · last mo.Coloradans awoke to hazy skies this week, as smoke from multiple large fires burning across the West deemed air quality “poor” and “unhealthy for sensitive groups.” Assistant Professor Colleen Reid shares the health impacts and how we can minimize them ↓ https://bit.ly/4ffBcAM
CU Boulder has been named one of the world's leading institutions for climate science, ranking eighth globally in the latest analysis of the most highly cited climate research institutions by Carbon Brief. @cires.colorado.edu was also recognized, ranking No. 43 globally. https://bit.ly/4wkkgis

New dr.! Kevin Rozmiarek just presented his thesis research on methane emissions from Arctic thaw lakes. Boig congrats!! Big trail lake near Fairbanks is where it happens.
Presentations of the @csdms.bsky.social annual meeting are up for viewing! Very cool stuff on hydraulics, AI, topodata data and stakeholder modeling, all in compact 20 mins lectures. Landing page is here: csdms.colorado.edu/wiki/CSDMS_m...
Our office for 2 weeks… found floating glaciers and extremely cold water. Lots of data collected and instruments in place. Thanks to a great team!
Why are the Rockies rocky? New work from Matt Rossi and friends -
CIRES@cires.colorado.edu · 2mo agoWhat makes the Rockies rocky? ICYMI — scientists from CIRES, INSTAAR, and CU Boulder revealed that the distribution of bedrock and thin, patchy soils in the Rampart Range in Colorado is controlled by topography, erosion, and forest structure. Read the story: cires.colorado.edu/news/topogra...
Happy to say that Dr. Josie Arcuri successfully defended her PhD Thesis yesterday. Thesis is not called "River Ice Matters" - but that is what her research revolved around. Josie picked up some field skills on the way, but hydraulic and morphodynamic river modeling is her jam. Huge congrats!
