And a 4th reminder that a transition to 100% WindWaterSolar reduces the annual total tonnes of mining in the world by >84% despite the need for precious metals, which are a trivial component of total mining tonnage.

🧪🍎📃 Important new study: Animal products, especially beef, pose much higher extinction risks for wildlife than grains, legumes, or vegetables. This means shifting land use toward more plant-based diets can give greater opportunities to restore biodiversity and help save species from extinction.

The Caspian Sea is shrinking at record speed – water levels falling up to 30cm a year. Simon Goodman (Univ. of Leeds) warns this is a glimpse of climate risks we all face. These changes are here, now. We need forward-looking plans to adapt, and to act without delay.

Thanks for the clarification! I appreciate the character limits, but I think it's good to include the assumption of current policies when giving the 97% certainty. It's important to also communicate that 2 °C is still (likely) avoidable if we implement proper mitigation policies.

Crossing 2°C is 97% certain (UNEP, 2024) IPCC SR1.5 (2018): “Coral reefs … projected to decline by 70–90% at 1.5°C (high confidence), with larger losses (>99%) at 2°C.” Perry et al. 2025: “If warming exceeds 2°C, nearly all reefs (≥99%) will be eroding by 2100. www.nature.com/artic...

Montie thinks this a beautiful sight. It was recorded from very close to St Thomas' Hospital, where a doctor has given us a much less beautiful insight into that day. Montie is such an idiot. bsky.app/profile/ceeb...

100% Greenwashing. Any ruminant industry claiming this is BS

After working on it for 20 years, my conclusion is: bsky.app/profile/city... At the heart, it's a social contract problem, the hardest kind of problem when the benefits of the status quo are concentrated in the same group that needs to act.

I've been working on #climate issues for years, but every now and then I step back & think how unbelievable (and sad) it is that scientists have shown for decades we're literally changing — in a bad way — the climate of the entire planet and yet society refuses to deal with that existential threat.

Dr. Rob Young: "This is unsustainable over the long run. I mean, we cannot hold every beach in the U.S. in place forever by doing these projects. We're going to run out of sand, it's going to get too expensive, so it really is a crisis, I think, that we haven't completely come to terms with."

Let’s check on who’s most responsible for climate change.

This is awesome...Scientists breathe new life into climate website after shutdown under Trump

here’s a version where the POV is blacked out whenever the driver takes their eyes off the road

Not just an attack on “experts” or science. It’s an attack on facts, knowledge, education or anything that could support someone questioning their iron rule. The bedrock of totalitarian, authoritarian regimes and dictatorships. That’s what RFK Jr is calling for. Only the dictator knows “the truth.”

We’re filling the atmosphere with CO2 like a bathtub with water. Most of it stays for millennia. That is why the cumulative emissions (the total amount, as pictured here) and not yearly emissions determine the amount of #globalwarming.

EXTRAORDINARY HEAT IN THE RUSSIAN ARCTICS Mind blowing anomalies persist in the same area. Still 21C at 73 latitude at Dikson Island ,24.3C at Karaul at 70 latitude, 3C above any temperature ever recorded that late. September will start by pulverzing every record in the area.

🧊 Arctic wetlands leaking more methane A new study estimates boreal–Arctic wetlands and lakes emit 34 Tg CH₄ per year today, rising ~31% by 2100 under moderate warming, mostly from warming-driven increases. 🔗 www.nature.com/articles/s41... #SciComm #ClimateCrisis #Methane 🧪

Even more worrying: the tipping point where the shutdown becomes inevitable appears to be when deep convection in the northern Atlantic stops. This tends to happen in the next few decades in these models, see two examples. Despite the models not even including Greenland ice loss!

I was shocked when I first saw these results from standard climate models used in IPCC reports: for high emissions, the Atlantic overturning circulation #AMOC shuts down in all 9 models that ran past 2100, and is well on the way to shutdown by 2100. Our paper on that is out today.🧵

New study: AMOC, the Atlantic Meridional Overturning Circulation, could already start to collapse now (before or around 2025, 25% probability), even under current 'moderate' emission trajectories. For NW-Europe, this would mean much colder winters, stronger storms and less precipitation.

Revealing #Norway's climate contradictions

By 2022, it had increased almost 18-fold to 70 kilograms. It’s not only the amount of meat consumed that’s changed: people in China also eat a more diverse mix. In the 1960s and 1980s, almost all meat came from pork. Today, pork still dominates, but it is joined by more poultry and beef.

Meat consumption is strongly correlated with income: as countries get richer, they tend to have more diverse, meat-heavy diets. However, as the chart shows, meat supply per person has increased significantly over the last sixty years. In 1962, annual consumption was just 4 kilograms per person.

Over the last six decades, China has rapidly increased and diversified its meat consumption
