PIK authors have retracted their study on the economic commitment of climate change. Scientific self-correction is essential; the team took the concerns seriously. Economic risks from global warming remain significant, especially in vulnerable countries. https://t.co/y3HvSe3u16

It's decided. Europe is closing the tap on Russian fossil fuels once and for all. Energy independence starts now ↓

“COP30 was meant to be the COP of ‘Truth and Implementation’ - this failed", says PIK Director @jrockstrom. "We don’t need more negotiations; we need implementation. Within 5–10 years we will breach 1.5°C, entering dangerous terrain for billions.” https://t.co/mNpBDe1JjH

No #COP30 agreement yet, but the science is clear: warming will overshoot 1.5°C, with escalating risks for people and key Earth systems. Science shows a way back: fossil-fuel phase-out, nature protection, carbon removal. New commentary. https://t.co/kzTDClDdCV

#COP30 update: I'm deeply concerned; national delegations have not set in motion a credible workplan for a global fossil-fuel phase-out / ending deforestation. With fellow scientists, we shared our scientific assessment with President Lula yesterday👇 https://t.co/LtKc6dax5R

“We need to start now to reduce CO2 emissions from fossil-fuels, by at least 5% per year. This must happen to have a chance to avoid unmanageable & extremely costly climate impacts affecting all people in the world.” PIKs @jrockstrom via @guardian. https://t.co/TdLluU5zB3

Scientists at Planetary Science Pavilion on #COP30: Most of the 1.5°C CO₂ budget is gone. 2025 emissions still rising. ~4 years of budget left. We need 5% cuts yearly & roadmap to phase out fossil fuels. Science must stay in the text, not be scrubbed. https://t.co/WXj3WOC5XR

We must hold on to 1.5°C, but that means governments need to do far more. With emissions still rising, the only path left is to return below 1.5°C after a temporary overshoot. A brief reflection with my PIK colleagues on where we stand and the road ahead:

The road back to Paris: The world will likely exceed 1.5°C within the next decade. Science shows it’s still possible to return below this limit by century’s end. PIKs #Edenhofer, @jrockstrom, @GunnarLuderer , E. Kriegler on pathways back to safer levels 👇 https://t.co/38XGJjcn50

What science tells negotiators at #COP30: The 1.5°C limit will very likely be breached within the next decade. People are already suffering from extreme events. Science shows a path back is still possible. New blog article on what needs to happen next. https://t.co/z72jkqqGJ8

Continuing to pollute our minds & the planet. The world needs to stop this manipulation & denial, & invest in a global counter movement for truth. The truth of existential risks on our watch. Truth of sustainability as the only route to prosperity & equity https://t.co/c9SUBIDd49
