Ahead of #COP30, a team of climate policy experts incl. PIK director @jrockstrom warn in a commentary in Nature that low-quality carbon offsets are undermining global decarbonisation efforts, calling for stronger standards, real removals, fewer excuses: https://t.co/i7gnRHbqoC

If the likelihood of a catastrophic event is > 10% then the Risks are unacceptable high. This is the point we have reached on scientific evidence for AMOC shutdown. This is the "Don't look up moment" for risks of liveability on Earth

“The new EAT Lancet report gives clear guidance on how to feed a growing population without breaching Earth’s safe limits,” says PIK director @jrockstrom. “What we eat can save lives, cut emissions, halt biodiversity loss, and build a fairer food system.” https://t.co/jZX7B4qN6v

Launching the EAT-Lancet report today on Healthy, Safe and Just diets. A global science assessment giving key guidelines for transforming our world back within the safe operating space on Earth. Highlights? Save 15 million lives/yr, cut emissions with 50 %

"No more climate change worship", Hegseth tells US military leaders 🙄. They know better. I know that, having been invited to speak at a NATO workshop on Climate Change Security. Climate science is not woke or religion or whatever, it’s physics. It got two physics Nobel prizes.

The world has lost a global leader for all life on Earth, Planetary Guardian and wonderful human being https://t.co/M2kRjOlIU6

Pope Leo blesses 20000 year old melting ice from Greenland Icesheet. His holy father stands by science and calls for humanity to protect God's creation, which is rapidly approaching irreversible tipping points. https://t.co/XC8gJFSaL2

🆕 Four key parts of the Earth’s climate system are destabilising. Researchers analysed the interconnections of the #Greenland ice sheet, the #AMOC, the #Amazon rainforest and the South American monsoon system. All four show signs of diminished resilience: https://t.co/ssAYP2YmkR

Another expert review of the science behind the endangerment finding, this time from health professionals. they conclude that CO2 emissions "pose a clear and indisputable danger to human health and well-being." https://t.co/dzlq5niYx8

This week at the @UN Climate Summit, I addressed world leaders: science is clear, we face a planetary crisis. Solutions exist. The window to a manageable climate future is still open, but just. Failure is not inevitable. It is a choice. Read more:

More than 3/4 of Earth’s support systems are outside the safe zone. Ocean acidification is the latest boundary breached. The warning is stark, but failure is not inevitable. It is a choice. Read the 2025 Planetary Health Check here: https://t.co/ySl8Cag5ye

"Seven of nine planetary boundaries now breached – ocean acidification joins the danger zone," says PIK director @jrockstrom presenting the key findings of the Planetary Health Check 2025. #PlanetaryBoundaries https://t.co/sePpqOHlIA

New Report by @Ember_energy shows that > 90 % wind and solar projects commissioned worldwide in 2024 produced power more cheaply than the cheapest available fossil-fuel alternative. Bad for planet and Bad for economy to bet on oil, coal & gas

Top hurricane expert Kerry Emanuel on the DOE scam climate report: “The DOE is presenting a distorted view of the science of climate effects on extreme weather that is bound to mislead the public.” https://t.co/6vWCekmnNs

Wow. Check this out. Politicians actually trying to solve problems can achieve a lot! https://t.co/Q4WFj5Vykh

The new edition of the @FrontiersIn Planet Prize is open now for nominations until October 2025. We need breakthrough science that advances Earth system understanding and delivers solutions to keep humanity within planetary boundaries. https://t.co/RcmYfTptO3

Weekend watch tip: Have you ever wondered what astronauts & the #climatechange planetary boundary have in common? The new explainer video from the Planetary Boundaries Science Lab explains more, with PIK Scientist Levke Caesar. #PlanetaryBoundariesScience https://t.co/4ozdNbex2V

I joined @wef's Radio Davos. Science is clear: 1.5°C is a physical limit, not a goal. We already hit 1.55°C in 2024, costing >$200bn. Overshoot is inevitable. Every 0.1°C matters. Good news: planetary boundary aligned business is profitable & resilient. https://t.co/igBzpA3MAj

Possible #AMOC shutdown after 2100 in high-emission future: new study with PIK scientist @rahmstorf finds that this would cut the ocean’s northward heat supply, causing summer drying & winter extremes in NW Europe + shifts in tropical rainfall belts. https://t.co/antBxFBsRQ
