🌍 You don’t need to be a climate scientist to shape the future of our planet! You need curiosity, perspective, and willingness to collaborate. 🧩Climate risk isn’t just numbers, it’s societies, ecosystems, decisions, narratives, uncertainty, and the futures we imagine. benasque.org/2026climate/

Is the Atlantic Ocean circulation close to tipping? Hear the latest science as I presented it last month at the ATLAS25 event in Helsinki. Let me know if anything is unclear, or if you see good reasons why your government shouldn't immediately act on this. 🌊 youtu.be/ULJXqOZuY-8

Assessments of government action on climate change—and public desire for climate action—should always explicitly consider how much cajoling and lobbying and pressure from oil and gas there is to do nothing. This is a fight; not (just) a technological transition. www.theguardian.com/environment/...

New study in Nature by Lin et al shows how the sea-level rise from the melting Ice Age ice (a total of 120 meters rise) ended thousands of years ago. Until our fossil fuel use started a new phase of rising seas. Graph shows the global mean rate of sea level rise. 🌊 www.nature.com/articles/s41...

New study explores how marine heatwaves contribute to coral bleaching. While deeper coral reefs are often viewed as potential refuges from climate change, we suggest they often experience higher thermal stress and bleaching levels compared to shallow reefs iopscience.iop.org/article/10.1...

People need to plan for climate risks. The research is there, but the usability for stakeholders can be limited. We introduce the reversal of the impact chain approach for actionable climate information that allows linking local risk levels directly to GHG emission. www.nature.com/articles/s41...

Reversal of the impact chain for actionable climate information - Nature Geoscience
Providing actionable climate information requires an end-user focused approach that links specific local climate risk thresholds with global emissions pathways.

Systematic attribution of heatwaves to the emissions of carbon majors - Nature
Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

What if companies disclosed climate risk the same way insurers analyze it: with event-based probabilistic models that show what could happen, when, and with what likelihood? Check out our new paper in Environmental Research: Climate to learn more! iopscience.iop.org/article/10.1...
