Landmark ruling in the Advisory Opinion by the ICJ on Climate Change. 1.5 degree C is legally the Planetary limit. All countries are legally obliged to comply. Even fossil-fuel subsidies can be illegal. States have duty to solve the planet crisis and can be held accountable.

📢PIK & @MPI_GEA are hiring: Earth Resilience Analyst ⁉️postdoc to explore planetary resilience, tipping points & planetary boundaries 🧪 Earth system/climate science 💻 HPC & modeling 📍 Potsdam | Start: 01.09 | Deadline: 20.07 🔗 potsdam.pi-asp.de/bewerber-web/?…

Tipping points: Window to avoid irreversible climate impacts is ‘rapidly closing’ carbonbrief.org/tipping-points…

Following the UN International Court of Justice Cimate ruling today on all countries liability to hold the 1.5°C limit - this would be probably be illegal under international law: E.P.A. Is Said to Draft a Plan to End Its Ability to Fight Climate Change nytimes.com/2025/07/22/cli…

In most of the world day-to-day weather variations are still much larger than long-term global warming. As a result, both daily record highs and daily record lows remain common. However as the world warms, new daily record highs consistently far outnumber new daily record lows.

China is building a single mega dam project that will output power equivalent to 38 nuclear reactors. Truly mind-boggling scale as China cements its place as the world’s first electrostate.

Incredible temperature anomalies in the Arctic Circle — especially around Scandinavia — with temps up to 8°C above normal. Ecosystems in this region aren't accustomed to temperatures above 30 °C At this rate, "Santa" will need sunscreen more than thermals. #ClimateCrisis #Arctic

📺 Friday watch tip: How do we know Carbon dioxide is a greenhouse gas? The new explainer video from the Planetary Boundaries Science Lab @planetarygdns shows you how with a simple experiment. #ClimateChange #PlanetaryBoundariesScience #SciComms 👉 youtube.com/watch?v=cYQ9dB…

New PIK study: Ambitious action on land use and food systems can limit warming to 1.5°C and ease pressure on multiple planetary boundaries, especially with food system reform. Yet: all five assessed planetary boundaries still exceeded by 2100. sciencedirect.com/science/articl…

New comment in @TheLancet: Planetary boundaries & health are inseparable. Breaching planetary boundaries already costs lives, through climate extremes, water stress, pollution & rising health threats. Science must drive the transformation to protect both. thelancet.com/journals/lance…

Pasterze (Hohe Tauern, AT) 1938 | 2025 Staggering loss of volume o the largest Austrian glacier... still for few days!🔥 When the (now tiny) icefall breaks up, it will no longer be the largest ice imass in Austria! @LanderVanTricht

The Mediterranean Sea is now measuring off-the-scale warmer than anything we've ever seen before for this time of year. If this trend continues, the consequences for marine life and ecosystems in the region will be devastating.

Coming up this Wednesday, 6:30PM CEST: Announcement of the 2025 edition of the Gulbenkian Prize for Humanity, @FCGulbenkian. The prize recognizes climate action that is not only science-based and transformative, but also has humanity in focus.

I support EU commission target of 90% emission reductions by 2040. But, it must be fully delivered domestically. The proposal of allowing ”flexible” offsets (compensate failed reductions at home with investments abroad) is not aligned with scientific necessity, and thus a mistake

🥵The weather station at PIK in Potsdam has recorded the driest first six months of a year since measurements began in 1893 – with only 146.8mm of rainfall. The long-term average for this location in the first half of the year is around 300mm. pik-potsdam.de/en/news/latest…

This important paper passed under the media radar. It analyses a key indicator of the stability of the Atlantic ocean circulation #AMOC, in measured ocean data. It finds that most climate models get this wrong, and thus have an #AMOC that is too stable. agupubs.onlinelibrary.wiley.com/doi/full/10.10…

Believe it or not, the usual suspects are trying to sell the little blip at the end of the Antarctic ice loss curve (due to a few strong snowfall events in East Antarctica) as proof that "global warming is a hoax". It just shows once again that "climate skeptics" just fool you.

The 6th Villars Distinguished Lecture🙌! Experts unite with Villars Fellows for a stable earth system.🌍 @jrockstrom calls for global sustainability transformation! #VillarsInstitute #VillarsSymposium #VillarsFellows #PlanetaryBoundaries #JohanRockstrom

In the 6th Villars Institute Lecture, @jrockstrom of @PIK_Climate stressed the urgent need for transformative climate action. Together, we can achieve a sustainable future! 🤝 #VillarsInstitute #VillarsSymposium #PlanetaryHealth
