Climate tipping points are being crossed, scientists warn ahead of COP30
Global warming is crossing dangerous thresholds sooner than expected with the world’s coral reefs now in an almost irreversible die-off, marking what scientists on Monday described as the first “tipping point” in climate-driven ecosystem collapse.

📄 A new report out of the @elpcenter.bsky.social highlights how climate change is affecting the Great Lakes — warmer waters, less ice cover, and shifting ecosystems. See what the data show:

Getting excited for #CSEE2025!

On Wed morning I’m organizing (& talking in) a symposium - along with Zach Miller and Maxime Clenet - that will bridge theoretical and empirical approaches to understanding spatial and temporal dynamics.

Then @sweeet-ecoevo.bsky.social symposium in the afternoon! 🙌
