Most of the scientists at the nonprofit that I cofounded, including my two cofounders, came from NCAR. It’s hard to overstate the importance of this place for climate science.

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

After 2 years of war, 98% of tree cropland and 75% of greenhouses in Gaza have been destroyed. Remote sensing maps tracking the progression of damage can help identify the best ways to remediate the land & rebuild Gaza’s agricultural sector. #AGU25 My latest for @eos.org: eos.org/articles/98-...
98% of Gaza’s Tree Cropland Destroyed by Israel - Eos
Maps based on remote sensing analysis could inform remediation efforts by identifying whether agricultural lands were damaged by bombs, debris, or forced displacement of its caretakers.

I love how being a librarian means I'm learning new things *all* the time. I've got a PhD in oceanography, but this morning I was answering a reference question & learned about ocean spiciness & how seawater can be "spicy" or "minty." 😍 TY to the person who asked about velocities of deep currents. 🌊

In Science, a new reconstruction of global sea levels spanning the past 4.5 million years reveals that oceans once stood up to 20 meters higher than today and links the waxing and waning of ancient ice sheets to shifts in Earth’s temperature and carbon dioxide cycles. https://scim.ag/42STXUm
