Congratulations!!!

A sad day for Brunonians

Overlooked and extensive ghost forest formation across the US Atlantic coast - Nature Sustainability Large swathes of standing dead trees or ‘ghost forests’ can form owing to rising sea levels in coastal areas, but the extent to which this occurs is unclear. This study maps ghost forests at the indiv...

"Overlooked and extensive ghost forest formation across the US Atlantic coast" -- wow what a comprehensive analysis by Yeung, @xiyang.bsky.social et al. 🎉 www.nature.com/articles/s41...

Thank you, Ben! Stay tuned for Henry’s second paper :)

Next absurdity: Past or future collaboration with Chinese students and scientists would disqualify American researchers from access to funding. 🧪

What a pleasure to have a great science reporter willing to explore the swamps with us!! Great pre-read for a soon-to-be-out paper from #HenryYeung of the @xiyang.bsky.social lab

BREAKING: UVA rejects the Trump Administration's Compact.

In #drylands, plants don’t grow randomly — they self-organize into disordered hyperuniform patterns that help them use water wisely & endure extreme aridity. A beautiful hidden logic of nature, revealed in a new @pnas.org study doi.org/10.1073/pnas... including #Maestrelab alumni

One of Earth’s most vital carbon sinks is faltering. Can we save it? For decades, forest, grasslands and other land ecosystems have collectively absorbed up to a third of the carbon dioxide we emit each year - but this climate buffer may be collapsing far sooner than a...

Over the past two years, the land carbon sink appears to have weakened dramatically, driving the largest one year jump in atmospheric CO2 on record in 2024. Is this the end of the land carbon sink? I asked around for @newscientist.com.

AI reveals vast 'ghost forests' along U.S. coast, work by Environmental Sciences PhD student, Henry Yeung.

Good reporting on widespread Douglas-fir mortality in SW Oregon.

I lived on the edge of the Ashland watershed mentioned in the article ca. 2012-2014.

Even then I was seeing patchy mortality from crowding/drought that I knew would get much worse as temps warmed.

AI reveals vast ‘ghost forests’ along U.S. coast Machine learning method counts nearly 12 million dead trees, many likely killed by rising seas

I joined a team of ecologists wading through the muck of the Carolina coast in search of "ghost forests" killed by rising seas for @science.org. We were guided by a a new map that reveals millions of dead trees standing along the East Coast, marking an overlooked consequence of climate change...

AI Data Centers Are Sending Power Bills Soaring Wholesale electricity costs as much as 267% more than it did five years ago in areas near data centers. That’s being passed on to customers.

Electricity now costs 267% more (!!) for 1 month vs. what it cost 5 years ago near data center hotspots. Awesome reporting from Josh Saul @dinabass.bsky.social Leonardo Nicoletti @naurtorious.bsky.social Demetrios Pogkas (gift link) www.bloomberg.com/graphics/202...

We mourn the passing of our Editor-in-Chief Steve Long.

His vision to establish one of the first journals dedicated to Global Change over 30 years ago was truly ahead of its time. Through GCB, researchers have demonstrated that biology and ecosystems are not simply victims of global change..

I'm happy to share a paper in Science Advances that makes the case for a weak land carbon sink, drawing upon JPL and Chloris biomass time series. To close the budget with a net land sink of 0.8 Pg C/y from 2000-2019, we propose increases in the ocean sink and decreases in fossil fuel emissions.

Amazing dataset!!! I can imagine a lot of new findings in the coming years as a result of this effort. Kudos to the team!

Trump Deals A New Immigration Blow To International Students Trump officials have proposed a new rule limiting international students to fixed periods of entry, making a U.S. education more precarious.

Trump admin planning to change student visas from lasting for duration of academic program to fixed 4-yr term, and then much harder to renew
Could destroy US ability to attract global talent, particularly those seeking advanced degrees in STEM. The median time to complete a PhD is 5.7 yrs per NSF.
