Our first Lead Author Meeting of the #IPCC Seventh Assessment Report was an incredible experience last week! Merci @ipcc.bsky.social!
Now, we are writing our way towards zero-order-draft (ZOD).

Yes, this week Lead Authors for the @ipcc.bsky.social Seventh Assessment Report (AR7) are meeting in Paris — almost 700 of us across all three working groups!
As IPCC Chair Jim Skea shares, there's even some highest-level climate diplomacy happening beyond the plenary sessions. 👇

Hey Cryoverse! 👋
If you need any motivation to call for action on the #AmbitionForMeltingIce at #COP30, check out the Glacier Casualty List. It's a global summary of 'critically endangered' & 'disappeared' glaciers and their stories.
It's really happening. 🧊💧
