Quote: #Burgerberaden zijn daarnaast nooit zonder risico. “Zonder goede begeleiding kunnen ze polarisatie juist vergroten.” Maar in Nederland was het wél een succes, met name door de intensieve rol van #moderatoren.

175 Nederlanders die totaal verschillend over klimaat dachten - en denken, komen toch met ‘impactvolle adviezen’ aan de politiek.
Sceptici bleven sceptisch, bezorgden bezorgd - wel is er meer respect voor elkaar.
In gesprek blijven is niet onbelangrijk ...

Het is heel simpel: Israël pleegt genocide.
Luxemburg, Spanje, Ierland en Slovenië stuurden een brief aan Kaja Kallas. Daarin stelden ze dat Israël de voorwaarden voor het handelsverdrag met de Europese Unie heeft geschonden. En dat is natuurlijk ook zo.

"What Europe needs is not yet another scramble for new sources of fossil fuel imports, but a fundamental shift away from the demand that makes these shocks so damaging in the first place."
NEW RESEARCH: Up to 90% of industrial energy demand could be electrified with existing & emerging tech.
Under high-ambition policy, 51% by 2050 is achievable. 84% under the most enabling assumptions.
The technologies exist. The constraint is policy.

Use all this money spent on #fossil spending reduction (#subsidy) to aleviate real #energyPoverty, especially for #publicTransportation and #isolating old houses.

NEW ANALYSIS: My new article in @natenergy.nature.com argues Europe keeps responding to energy crises by changing supplier.
95% of EU oil and 88% of gas was imported in 2024.
The structural fix: reduce fossil fuel demand through electrification and efficiency.

Graphic produced by Climate Central showing daily global sea surface temperatures in °C for all years since 1982 with the long-term mean and 2026 annotated.
Global ocean sea surface temperatures have surged to the highest on record for this time of year!
Join me in our monthly webinar next week to discuss these recent global climate extremes, as well as reviewing the historic March heatwave.

Great citation and interview! NB: The link should be to @drkatemarvel.bsky.social
"Hope has two beautiful daughters; their names are Anger and Courage. Anger at the way things are, and Courage to see that they do not remain as they are."
One of my favourite quotes, attributed to St Augustine and embodied by @drkatemarine.bsky.social today.

Aal for female questions. That’s enough to make people think.
Coordinated disinformation efforts, harassment campaigns, strategic lawsuits, and personal assaults now accompany research in politically contentious fields.
Worth reading if you care about science!

Begin april werd in De Bilt de eerste dag van het jaar met een temperatuur van 20˚C of meer gemeten. Door klimaatverandering zien we steeds vaker hoge temperaturen in het voorjaar.
Die Wissenschaftssendung NANO gestern zu den neuen Studien zur Abschwächung und Gefahr eines Versiegens der atlantischen Umwälzzirkulation #AMOC. Das Risiko ist danach viel höher als bislang gedacht. 🌊

Line graph time series of March monthly mean carbon dioxide abundance from 1958 through March 2026. There is a long-term increasing trend and seasonal cycle. Current Earth Day 2026 levels are around 431 ppm for this week in April. And the first Earth Day in 1970 was around 328 ppm.
Happy #EarthDay! 🌍🌎🌏
Here's an updated graph of how much carbon dioxide (CO₂) has changed since the first Earth Day, which is driving recent climate change.
NEW: “Arrest as many people that touch you as you want to," Gregory Bovino told Border Patrol officers in 2025.
But a review of hundreds of such arrests shows that charges brought against protesters and bystanders repeatedly fell apart under scrutiny.

Consider (outside) sunscreens and asiabatic cooling instead of #airConditioning!
Graph showing Arizona cooling degree days in March from 1895 to 2026. 2026 is much higher than any other year. Graphic is produced by NOAA/NCEI.
As unseasonable heatwaves arrive earlier and earlier in the year, the length of the air conditioning season for energy demand will also grow. Check out March 2026 cooling degree days compared to the historical record for Arizona.

De snel stijgende temperatuur in het Noordpoolgebied zal de piek in voedselkwaliteit voor planteneters vervroegen, met name in Europa. Dat blijkt uit nieuw KNMI onderzoek in de Journal of Biogeography in samenwerking met de Universiteit Groningen en anderen.
After a review of coverage by nine legacy UK newspapers, J. Painter, S. Cocks, and S. Hayes find that media framing is playing a significant role in shaping political debate around Net Zero, often without balanced evidence. See their new paper below. www.tandfonline.com/doi/pdf/10.1...
I don’t want my EV to be high speed! 😁
Breaking: New study using observational constraints projects that the Atlantic Ocean circulation #AMOC will weaken ~50% by 2100, even for medium emissions and without Greenland melting. 🌊
More realistic models means stronger weakening - not entirely unexpected.

Bad news - we'll soon blow through the carbon budget for stabilizing global temperature at 1.5C
Good news - progress on clean energy suggests it is possible to stabilize by 2C www.nature.com/articles/s41...
What does the science say? Neither is a magic threshold. Every bit of warming matters.
@toengel.net the #philipsHue app added a looking glass for help. It covers one of my on-off switches. Can this button be turned off or placed somewhere else on the screen?
@enexisnetbeheer.bsky.social het is vandaag zonnig 😀 hoe laat verwacht u de top van de zonnepiek op het net (in Drenthe)?

Working on climate change often comes with frustration over the lack of progress.
But progress is happening, and it’s worth celebrating when it does.
One piece of good news from my corner of the world: #Copenhagen has now fully electrified its bus fleet 🙌 🚌 ⚡
