Over last 2 months, the national ave. temp. anomaly 🇫🇷 has reached +3 °C/1991–2020... crazy for a 60-day period! 🔥

Warmest ever recorded late winter at +9.4 °C, far ahead of +8.7 °C in 1990 (at the time, Feb. 1990 was considered an exceptional winter heatwave!) 😱

Random thought - maybe re-prioritising the allocation of public space isn’t increasing “division” of society, but it’s just making pre-existing division between privileged vs. non-privileged groups more obvious - and the previously privileged don’t like it?

‘This was forged’: Residents deny sending emails pushing Bay Area air policy change At least 10 people listed as sending letters in favor of an air quality policy change said they have no recollection of doing so and weren’t even aware of the proposal in the Bay Area.

🚨 A new frontier of coordinated disinformation.

Fossil fuel industry front groups are using AI platforms to flood clean air regulators with fake public comments—submitted under real residents' names, without their consent.

From climate action to climate Agency: Mapping social drivers and the opportunity structure for global decarbonization

🌱 When does isolated #climate action “densify” into durable forms of climate agency?
@stefanaykut.bsky.social @antjewiener.bsky.social propose a framework to study when climate action stabilizes, expands, and institutionalizes into lasting capacities.

Hegseth: "We will keep pushing, keep advancing. No quarter, no mercy for our enemies."

No quarter is the refusal to take prisoners and instead just execute everyone. It's been considered a war crime for over a century.

The Framing Game: Why We Call Affordable Mobility “Too Costly” While Subsidizing Cars. Or: How a society convinced itself that saving money is actually spending it

“We’ve all trained ourselves to see car infrastructure as ‘normal’— and therefore its costs as invisible. Roads aren’t expensive, they’re just there. Parking spaces aren’t subsidies, they’re just ‘necessary’.”

"By 2050, the average public debt of EU member states could be 58 percentage points (pps) higher than official forecasts unless #climate risks are addressed. "

#ClimateEmergency

If we invest in climate action now, the EU can reduce debt increases in future decades.

But that requires a political choice: reforming fiscal rules to enable investment, European borrowing for common projects and fair taxation including taxing the ultra-wealthy.

🚨NEW: The impact of climate change on our economic stability is being hugely underestimated.

Our latest analysis shows climate damage could drive the EU’s debt-to-GDP ratio 58 percentage points higher than official projections by 2050.

All signs continue to point to an exceptional, long-duration, and record-breaking to (in some cases) record-shattering March heatwave initially centered across U.S. Southwest but expanding to much broader region next week. This is effectively a full-on summer heatwave in March.

UK energy prices are soaring – and propagandists want to sell you a false reason why | George Monbiot The war on Iran has put fossil-fuel prices centre stage, but don’t believe those who tout ‘maximising the North Sea’ as our salvation, says Guardian columnist George Monbiot

If it's sometimes hard to tell the difference between fossil-fuel lobbyists and the billionaire press, that's because there isn’t one.

How Paris beat the car Though chaotic, the city’s transition has become a global role model

The city’s transition away from the car, tho fantastically chaotic, has become a global role model. Under mayor @annehidalgo.bsky.social, Paris was “the most influential city in the world”, says Canadian urbanist Brent Toderian. Hidalgo, stepping down after 12 yrs, exulted: “The bike beat the car.”

Across England, we are shut out of the majority of our woodland: so much of that which is off limits is used for pheasant shooting or private commercial forestry.

Nice thread on how to tell climate stories that inspire action.

Especially Tip 2: Stories don't just inform people what happened - they tell people what change feels like.

Also @albomp.bsky.social govt:

⚠️ #FutureGasStrategy to 2050 & beyond
⚠️>46,000km2 opened 4 offshore Oil+Gas exploration
⚠️ Sea Dumping Bill that'll enable high-risk CCS
⚠️ Fossil fuel subsidies of $15 billion in 2024-25, $16.3 billion in 2025-26

"We must always take sides. Neutrality helps the oppressor, never the victim. Silence encourages the tormentor, never the tormented. Sometimes we must interfere."
