A startup falsely blamed for triggering floods pitches cloud seeding to lawmakers Rainmaker Technology is spending hundreds of thousands of dollars on lobbying and gold-framed Metro ads in a play for national attention.

Rainmaker is running a $100,000 Metro ad campaign as part of a larger influence effort by the cloud-seeding startup.

It’s a case study of how in the Trump era, it’s better for a startup to be talked about in Washington — even inaccurately — than not known at all. www.politico.com/news/2026/02...

Ecologists! Plz share! **ESA abstracts due Feb 19th this year - meeting is last week in July in Salt Lake City** This is a change from our normal first week in August bc this is rescheduled from COVID cancelled 2020 meeting. We're hard at work to prepare a great meeting for you.

Very excited to read this!

Trees use predominantly summer water in the Ressi #experimental #catchment.
Thank you to Giulia Zuecco for leading this work!

During the growing season, soil and plant water had a dominant summer origin but seasonality had a major role on their temporal origin.

Application — paleoCAMP

Exciting news! Student applications for paleoCAMP 2026 are open! Are you a graduate student working on any aspect of past climates or environments? Apply to be part of our 2-week summer school in the eastern Sierra Nevada! More details here: paleoclimate.camp/apply

We are hiring!! Asst Prof of Environmental Biology and Public Health! "...interaction between biological systems and the environment as it relates to epidemiology and/or public health."

My colleague Sarah Batterman and others from @caryinstitute.bsky.social are organizing what looks like a great crash course on ecosystem ecology for graduate students at an exceptionally affordable cost:

New Precipitation Is Scarce in Deep Soils: Findings From 47 Forest Plots Spanning Switzerland We determined the new and young water fractions of soil lysimeter waters in 47 forest plots in Switzerland Soil characteristics such as lysimeter depth, soil field capacity and soil stoniness exp...

A new study w/ Emily Burt, @scottallenunr.bsky.social, et al. via @aguecohydro.bsky.social made possible by @bafu.admin.ch. We use >3500 lysimeter isotope observations from 47 sites over 3 years to measure how rainfall percolates into soils, with estimates of young water at different soil depths.

Big news! Huge congratulations to you and very best wishes for many successes!
