The core of the war in Iran is that we remain addicted to oil. If we had acted on science, away from climate crisis, we would no longer depend on fossil-fuels. Just like many actors are doing. War accelerates global warming. A vicious spiral. We all lose. mailchi.mp/75017dfaa31e/c…

Agriculture already produces enough calories to feed the world. Yet, hunger persists, writes PIK scientist Christoph Müller in Science Editorial: Food insecurity is primarily a problem of poverty and unequal access not agricultural production.👇 science.org/eprint/WG6TNM6…

Looking forward to joining the #VillarsOceanForum to present on how our oceans, poles and glaciers are ground zero for tipping points, and key indicators of planetary resilience. Thank you to the @VillarsIdeas team for your invitation.

Forest damage in Europe from wildfires, storms & bark beetles could rise by ~20% by 2100 even if warming is limited to 2°C: new study with PIK scientist Christopher Reyer. In high-emissions scenarios, the damaged forest area could even double. pik-potsdam.de/en/news/latest…

Significant acceleration of global warming since 2015, finds news PIK study with @rahmstorf Recent warming: around ~0.35°C per decade. 1970–2015 average: just under 0.2°C per decade. ➡️Current rate is higher than in any decade since records began in 1880. pik-potsdam.de/en/news/latest…

Scaling Conservation Agriculture can help shift food production back within Planetary Boundaries. It now spans ~200M ha globally and could reach 50% of cropland by 2050. Healthy soils are key to food security & Earth system stability. New article out now👇 cambridge.org/core/journals/…

13 climate scientists. The test case: AMOC stability, a domain with genuinely conflicting lines of evidence, where synthesis requires more than literature aggregation. Our work serves as starting point, not as a conclusion. Perspectives from colleagues welcome.

Where might #AI meaningfully assist without undermining what makes assessment trustworthy? We explored this question in collaboration with @GoogleDeepMind ETH Zürich @UZH_en @univmiami @imperialcollege @stripe. Preprint: arxiv.org/pdf/2602.09723 @LeippoldMarkus @anna_koivuniemi

3 Ocean & Earth System Science positions available: New PIK project “The Role of the Ocean in Earth System Stability” explores how ocean heat & carbon uptake, marine biodiversity and biosphere feedbacks shape Earth system resilience. 👉pik-potsdam.de/de/aktuelles/s…

NEW: Antarctic ice sheet not one tipping element, but interacting basins with distinct thresholds. ~40% of West Antarctic ice may be committed to long-term loss; parts of East Antarctica face risks at 2–3°C. @Ricarda_Climate @juliusgarbe @JonathanDonges pik-potsdam.de/en/news/latest…

Devastating floods have hit Portugal & Spain in past days, causing loss of life & billions of Euros in damages. How does climate change impact the flood risks from rain, rivers & rising seas? Watch my lecture Flooded Futures: What are We Planning For? 🌊 youtube.com/watch?v=wtd8ZF…

Flawed economics puts world welfare and economics at risk. The climate crisis is real, it is here now, and it could fundamentally threaten the global economy .theguardian.com/environment/20…

Once a distant climate risk, the destabilisation of the Atlantic Ocean circulation (#AMOC) is becoming a real security concern. @jrockstrom and Iceland’s Climate Minister Jóhann Páll Jóhannsson outline what can be done about it.👇linkedin.com/pulse/climate-…

Eating healthy food, prolongs your life, and gives major contributions to a healthy planet. This makes the food system transformation as important as the global energy transition to have a chance of prosperity and an equitable future for humanity on Earth rdcu.be/e0VYJ

Holding on to 1.5°C aligned mitigation pathways and science based targets is absolutely essential. In order to minimize overshoot, costs to investments & impacts on the global economy. And, it is doable, zero solutions are there and are winners ft.com/content/dedb20… via @ft

In the coming decades, global population & GDP growth are projected to increase & ultimately accelerate common drivers underpinning the triple challenge posed by climate change, biodiversity loss & pollution. Report shows the full scale of these impacts: brnw.ch/21wZjm1

Yearly wind power production. China leads the world; the US started its exponential growth some years after Europe but then caught up with the EU. Cheap wind power is now threatening fossil fuel profits, a powerful lobby with obvious undue hold over the Trump administration.

Sannolikheten för en kollaps av AMOC [systemet av havströmmar i Atlanten som reglerar havets värmeutbyte och klimatet i Sverige, Norden och världen] är nu så hög, trots osäkerhet, att det måste anses vara en oacceptabel risk. Som troligen kan undvikas. Norden måste visa ledarskap

"An economy driven by fossil fuels & extraction cannot continue without putting the planet at risk". 🚨 @jrockstrom, @PIK_climate in #Davos. The pathway to prosperity is clear: align with science, live within planetary boundaries, phase out #fossilfuels: now. ⏱️ #WEF2026
