Two years plus in the making... our paper building fair effort sharing directly into how integrated assessment model (IAM) scenarios are generated is out in Environmental Research Letters🧵 @iopp-environment.bsky.social @iiasa.ac.at doi.org/10.1088/1748-9326/aea34d

⚖️ New IIASA-led research shows that integrating fairness into climate models can change how the global mitigation effort is shared across regions while still achieving the same climate goal. The findings offer new insights for translating global ambition into action. 👉 iiasa.ac.at/news/sep-202...

Fairness informs how the world cuts emissions

Who cuts emissions fastest, and who supports others do so, are central questions in global climate action. New IIASA-led research shows that building fairness into climate models from the start can in...

"One of the workshop’s shared diagnoses was that the climate movement must broaden its struggle beyond carbon. This means organising around people’s material realities while confronting the elites and corporations driving destruction." theecologist.org/2025/nov/12/...

A brainwave in the heatwave?

Engaged academics and high-level strategists from the climate movement met to discuss movement strategy during a European heatwave last June. They released their summary report today.

Mid-high latitude lakes exhibit amplified heat release to the atmosphere due to an ice-loss feedback, revealing distinct responses to global warming between lakes in colder and warmer regions.
