Yesterday afternoon 14:09 in Lacanau Océan in France. A pale red sun through the smoke tinged everything in Mars style orange. Welcome in the climate emergency! Despite all denial of the fossil fuel lobby, it’s scientific fact: CO2 emissions heat up Earth & make fires worse. 🔥🔥🔥

When the story of why humanity didn't stop climate change is written, it will feature front pages like this. Even as the skies blacken with climate change-induced wildfires, right wing media continue their relentless crusade against measures to tackle it.

More than 60 years ago, the fossil fuel industry sponsored climate research. Industry leaders were amongst the first to realize the effects their products have on our planet's climate. And they decided to act. To act and save their business model, unfortunately.

When did States know enough to act on climate change? That question is no longer just historical. It's increasingly a legal one. Our 🆕 report provides evidence that many governments knew about fossil fuel-driven climate change far before they admitted: www.ciel.org/reports/what... 🧵

Professor @joerirogelj.bsky.social and Dr @robinlamboll.bsky.social have contributed to the latest Indicators of Global Climate Change (IGCC) assessment, showing human-induced warming reached 1.37°C in 2025. At current emissions trends, 1.5°C could be exceeded within around four years.

With all the July model runs now in, it is very likely that 2026 will see the largest El Niño event since records began in the late 1800s – and potentially by a truly mind-blowing margin. The median estimate is now 3.6C, roughly 0.8C hotter than the prior record (2.75C). www.theclimatebrink....

🌍 Cutting carbon emissions isn’t enough – we also need carbon removal. But planting trees or energy crops at scale can clash with biodiversity. Careful planning is key, says Professor @joerirogelj.bsky.social and colleagues. 🌱 #ClimateAction #Biodiversity #CarbonRemoval #Sustainability

Planting trees to remove carbon can harm the environment – or protect it: study highlights trade-offs

Carbon removal strategies may conflict with biodiversity conservation, but careful choices could bring benefits.

Den dritten Tag in Folge wurde in Deutschland ein neuer Höchstwerte seit Aufzeichnungsbegin registriert. In Coschen an der Neißemündung wurde ein vorläufiger Wert von 41.7°C Grad gemessen. Die vorherigen Spitzenwerte waren gestern Möckern-Drewitz (41.5 °C) u vorgestern Saarbrücken-Burbach (41.3°C).

Can land-intensive climate mitigation help protect biodiversity - or create new trade-offs? A new study by our researchers @rubenpruetz.bsky.social & S. Fuss shows 1.5°C pathways could halve the the combined loss of climate refugia compared with current policies iopscience.iop.org/article/10.1...

In a new study, published in Environmental Research Letters, we assess how much of today’s climate refugia (areas sheltering #biodiversity from climate change) may be lost in the future. 🌍🌡️ (Brief overview below) doi.org/10.1088/1748...

Both climate change and biodiversity loss are intertwined crises with severe consequences for people and nature. seedling On this #EnvironmentDay and every day, we remember the essential role of biodiversity in effective climate action.

Yesterday, Edition 3 of the State of Carbon Dioxide Removal Report was released. 🚨✅ Chapter 10, led by Sabine Fuss and Abby Lunstrum, provides update of estimated mitigation potentials and costs for various #CDR methods. 🔍🔦 (Brief overview below)

The State of Carbon Dioxide Removal Edition 3 is now live 🌍 Since the last edition, #CDR landscape has continued to evolve. Novel CDR deployment has grown, new policies have emerged, & fresh evidence has improved our understanding of future needs. Download here: www.stateofcdr.org/report/3rd-e...

In @theconversation.com @rubenpruetz.bsky.social, @joerirogelj.bsky.social, Sabine Fuss and Gaurav Ganti write that carbon removal strategies may conflict with biodiversity conservation in many instances: for example, planting trees and energy crops in pristine ecosystems such as savannas.

March in Western North America is deadly hot, completely above temperatures that would have been possible without climate change from burning oil, coal and gas. New record shatteringly rapid @wwattribution.bsky.social study www.worldweatherattribution.org/record-shatt...

My latest for @mongabay.com: Planting trees helps fight climate change & restore biodiversity. But a new study finds that land-intensive carbon removal projects like reforestation or bioenergy crops often overlap with global biodiversity hotspots.

My first paper had to be mailed to Stockholm, Sweden, and then mailed to reviewers around the world. Everything by mail! It was submitted, reviewed, revised, typeset, and published in 3 months. I feel bad for early-career scientists who can't find a single reviewer after 5 months. It's gotta change.
