🎉🎉NEW PAPER🎉🎉 "Out of the Forest and Into the Concrete Jungle" This is some of the work I'm most proud of to date: a new commentary co-authored with 15 amazing urban hydrology (or adjacent) folks after the 2024 WaterSciCon! Details and highlights below... 1/5 doi.org/10.1029/2025...

Out of the Forest and Into the Concrete Jungle: Challenges, Opportunities, and Innovations in Urban Hydrology

Urban hydrology lacks an integrative framework across biophysical processes, social mechanisms, and governance processes We provide a path towards unified conceptualizations, efficient implementa...

Science may be under attack, but inclusive science always prevails. This tee is more than just a statement—it’s a stand. 100% of profits go to AGU, which has supported scientists for over 100 years and continues to lead the charge to defend them today. Support science: buff.ly/khcOLvk

Vital research data is disappearing in front of our eyes! ⚠️ Right now, NOAA is being blocked from using satellite data to monitor sea ice loss. 😖 Not knowing how the Arctic is changing will not diminish its impact on our climate, it just makes us more vulnerable to the consequences.

The poor "Sea Ice Index" nsidc.org/data/seaice_... 😢 See thread for more on this tragic data loss: bsky.app/profile/zack...

Screenshot for the NSIDC Sea Ice Index, which says "This data set was recently downgraded to a “Basic” Level of Service. Learn more about what this means for users here" and "The Department of Defense (DoD) will stop processing and delivering the Special Sensor Microwave Imager/Sounder (SSMIS) data no later than 30 June 2025. The SSMIS data are used as input for this NSIDC-produced data set, which will therefore stop processing no later than 30 June 2025. Please contact NSIDC User Services if you have questions."

I was today years old when I discovered that the @wmo-global.bsky.social maintains a list of nearly all Earth observation missions 🛰️ ever launched, making it possible to query a variable and find every mission that produced it, past, present, and future and across all agencies in the world! 🤯

All hands on deck for the final biomass collection of Becca’s senior thesis looking at the physiological impact of increased salinity on native and invasive species from the Sacramento-San Joaquin delta! A beautiful day to count and cut shoots! 🌱

⚠️New preprint alert!⚠️ My student Paul Seibert's very first paper is in review, but you can already read up on his work establishing the impact of drought on foliar uptake ability for the grasses of our foggy study site in Point Reyes (with @eesaberkeleylab.bsky.social). 🌿🌁

Drought limits foliar water uptake in C3 perennial grasses

Rain, fog, and dew can all provide the conditions necessary to induce direct uptake of water into the foliage of plants. Although grasslands are known to have frequent leaf-wetting events, the capacit...
