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 ...

EU-landen worstelen met relatie met Israël, handelsverdrag nog niet opgeschort EU-lidstaten zijn het dinsdag niet eens geworden over het opschorten van het handelsverdrag tussen de Europese Unie en Israël. De kritiek op de economische bondgenoot van Brussel groeit, maar een aant...

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.

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.

Why this NASA climate scientist wants you to stay angry “I don’t think we rebuild science without getting mad.”

"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.

But a review of hundreds of such arrests shows that charges brought against protesters and bystanders repeatedly fell apart under scrutiny.

Exceptional twentieth-century slowdown in Atlantic Ocean overturning circulation - Nature Climate Change Cooling has been observed over the past century in the northern Atlantic, and this study presents multiple lines of evidence that suggest it may be a result of a reduction in the Atlantic meridional overturning circulation. The decrease in this circulation, particularly after 1970, seems to be unprecedented in the past millennium and melt from the Greenland Ice Sheet may be a contributing factor.

Our original 2015 paper is this: www.nature.com/articles/ncl...
And an accessible introduction to the Atlantic overturning circulation known as #AMOC for non-experts can be read here:

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.

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.
