Ah missed the story about Turkmenistan's giant gas leak in 2021 that we covered. Satellites are amazing, when used well! www.bloomberg.com/news/article...
New Climate Satellite Spotted Giant Methane Leak as It Happened
Equipment and software operated by GHGSat picked up eight simultaneous plumes from a field in Turkmenistan.

It's not often you can pinpoint real, positive change a journalist has caused. But as Turkmeni sources state, @dpcarrington.bsky.social's persistent and probing coverage of this issue has been critical to a change of policy, with massive implications. Big congrats www.theguardian.com/environment/...

An incredibly well-timed Landsat 9 pass captured the effects of yesterday’s catastrophic glacier collapse near the Nepal–Tibet border. The event was so massive that it was detected by seismometers around the world.
I am recruiting a PhD student to join my group at UC Irvine in Fall 2027 to work on the Coupled Tipping Dynamics of Ocean Circulation and Ice Sheets – details in the attachment below. Please share the position with your networks!
NSF just announced its GRFP solicitation due in October - deadline varies by field: www.nsf.gov/funding/oppo... Now for the bad news... * NSF estimates they will issue 1,500 awards, down from 2,500+ last year. * NSF removed STEM Education and Learning Research as a Major Field.
