- Reposted by Annika HögnerHow should climate science and policy respond to a potential exceedance of 1.5°C? We provide our perspective on this in a new @Nature comment 🔗 nature.com/articles/d41586-026-00247-y led by Gaurav Ganti with Sabine Fuss, @joerirogelj.bsky.social, @setupelz.bsky.social & Keywan Riahi 1/

- Reposted by Annika HögnerSpiralling global temperatures (1850-2025) The last 3 years really jump out, rather like 2015-6 did when we first produced this graphic back then. Now, 2015-6 looks rather cool... More on the spiral: doi.org/10.1175/BAMS...

- Reposted by Annika HögnerI've finally got around to curating a selection of films about the #climate crisis 🎥 There's lot of mediocre climate films out there, but for me these stand out head & shoulders above the rest 🎞️ They make excellent resources for classrooms, lecture halls, or community cinema's 🎬 Thread:🧵Plz RT
- Reposted by Annika HögnerThis is how climate injustice unfolds. There is both an economic logic to cutting emissions now & a moral imperative to rapidly scale up international finance for loss and damage and adaptation in the most vulnerable countries.

- Reposted by Annika HögnerThis is a good corrective to the BS narrative flowing through the Pielke/AEI/NYP/EID/DOE nexus. Their argument is designed so that we can never ever attribute extreme events to emissions - even singular events that would have *never* [for some suitable finite approximation] have happened before.

- Reposted by Annika Högner🚨NEW PAPER🚨 We all know the 2022 energy price shock fueled the cost of living crisis. It also caused a profit bonanza for the very rich. We show the US reaped the largest profits ($377bn) of any country. 50% went to the richest 1%, only 1% to the bottom 50%. A🧵 www.sciencedirect.com/science/arti...
