The case study of the Mendenhall Glacier in Alaska, led by PIK’s Donovan Dennis as part of the recent Global Tipping Points Report ( https://t.co/IIhPQFluOn) has now prompted the local newspaper @JnuIndependent to publish a really nice explanatory piece: 👇 https://t.co/oRFbsESsM0

What does it mean for Juneau now that Áakʼw Tʼáak Sítʼ, the glacier behind the little lake, has receded from the icy water?

Following the publication of two critiques & in conversation with the journal Nature, the authors of the study “The economic commitment of climate change” at PIK have retracted the paper. They will resubmit a new version of the paper for peer review. https://t.co/OSPAa59rQ9

Experts have mixed reactions to the recent U.N. climate talks in the Amazon. The talks, known as COP30, ended without a clear plan to phase out fossil fuels. U.N.

“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

The world bet on collective but voluntary action to keep global warming at a safe level.

"Too little was done too late”: New commentary with PIKs @jrockstrom & @JonathanDonges warns of rising planetary risks after a missed decade of action. Climate & biosphere pressures keep increasing, but stabilising the Earth system is still within reach. https://t.co/U78tkMKQA0

#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 are at a planetary crossroad. We are already facing danger. Suffering for billions of people and rapidly approaching tipping points in the Amazon and the Tropical Coral Reef systems and many...

“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

As president Lula tries to find common ground between negotiating countries, planetary scientists say emissions must be urgently cut

"The rate of warming is showing signs of accelerating" PIKs @jrockstrom gives an analysis of the current situation on climate & planetary boundaries at #COP30. The data suggests the world is heading for global temperatures not seen in millions of years. https://t.co/glUAvh700q

A shutdown of the AMOC, a crucial system of ocean currents, “cannot be considered a low likelihood risk anymore in view of the evolving science over the past years,” explains PIK scientist @rahmstorf via CNN. https://t.co/5XarYH3Mau

Without warm currents from the South Atlantic, Iceland would be much icier and stormier. Now, those currents are at risk of collapse and the country is preparing for this “existential threat.”

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
