Ring Index brings culture/mesocosm GDGTs into agreement with coretops. Not linear, not exponential — the T–GDGT relationship follows a logistic S-curve.

Reposted by Ronnie RattanasriampaipongKatherine Siegel @katherinesiegel.bsky.social · 07/07/2025The Dept of Commerce has forced the NOAA C&GC program (which supported my postdoc) to furlough their postdocs. Postdocs are at a precarious career stage - folks move across the country/world, often w/o much of a local support network 041
Reposted by Ronnie RattanasriampaipongMichael Griffiths @cavemangriff.bsky.social · 08/07/2025I was also a Fellow. This program brought me from my home country of Australia, providing me resources+networks that paved my career path to becoming a full professor in a US institution. Having now worked with many undergrad/grad/postdocs, I have witnessed CGC benefits to society at large. 0207
Reposted by Ronnie RattanasriampaipongJessica Tierney @leafwax.bsky.social · 07/07/2025One of the things that makes this Fellowship special is that unlike NSF fellowships it is open to non-citizens, with the aim of retaining climate science talent in the US. The furlough creates significant problems for non-US postdocs in how it complicates visa status 😳 1373

If we stop collecting climate data, it will not alter reality. It will make us less prepared to address the damage & pain human-induced, climate change generates.
