Glad to be speaking at ChangeNOW 2026.
My message: cities reliant on fossil fuels stay exposed — but cities that reduce energy use, electrify, and shift to clean local energy become secure and resilient.

Klímabajnokok | Beszélgetés dr. Ürge-Vorsatz Diána klímakutatóval

A Green Policy Center Klímabajnokok podcastjában beszélek arról, hogy hogyan alakult ki a klímatudatosságom, miért kulcsfontosságú a tudományos kommunikáció, és miért a rendszerszintű döntések hozzák a valódi klímaeredményeket.

Storage and reneqablw mixes solve intermittency by and large. Production could be diversified while oil less

Can people help on guidance whether #claude is a good alternative to #chatGPT, if I am used to the latter but want to switch?

Could the war in Iran trigger a global economic crisis? | The Economist Insider When will the Iran war end? Donald Trump has offered contradictory answers: he says America’s mission in Iran is “very complete”, may “go further” and also “depends”. Yet if America’s president declar...

Stunning how little (or no) connection is drawn from the present war-induced energy and economic shock to the urgency of the clean #energyTransition.

New paper out in Nature Clean Technology: renewables are growing fast, but rising energy demand—especially from data centers & cooling—risks slowing fossil fuel phase-out. AI can help climate solutions, but only with strong demand-side policies. 🌍⚡️

The whole developed world is doing this with many of our innovations, such as now also with #Passivhaus and #zetzeroenergy buildings. But "selber Schuld-kein Mitleid" as the Germans say. Well deserved on both sides - just disappointing to sit on the loser side. Well done, China, though!

"China is making more money from exporting green technology than America does from exporting fossil fuels." @economist.com

Sounds like an attractive blueprint for a 21st century #EU economy: green tech and innovation in the driving seat rather than heavy industry

And smaller cars. Trends towards larger and karger cars cause more and more traffic causualties

Why ‘green’ finance isn’t always as sustainable as it seems At its most basic level, sciencewashing entails using the vocabulary of science, and borrowing its authority, to claim sustainability outcomes.

"our study warns against different forms of #sciencewashing of #greenFinance (GF)

Evidence suggests a gap btwn the suggested possibilities and the actual outcomes of GF. Many products serve financial markets&wealthiest investors more than nature or communities."

Dreamt about engaging with the @IPCC 's Special Report on Climate Change and Cities #SRCities?

The expert review is ongoing, closing on December 12th:

It is the thousands of review comments that make the IPCC's reports so widely "owned", thus so impactful!

Sloponomics: who wins and loses in the AI-content flood? Against all odds, the deluge might be good for creators

The planet is heating up from increasing energy use. #datacenters are among the largest power demand growth drivers.

In this crisis, can humanity afford a #slop flood to drive energy related emissions even higher?

Swiss firm that captures carbon from air to cut workforce by more than 10% Downsizing at Climeworks comes amid economic uncertainty and ‘reduced momentum’ for climate tech

"Climatework’s flagship Mammoth #DACCS plant in Iceland, which has a nameplate capacity of 36k t of CO2/yr, captured 750 t in its first 10 months since opening, w net removals after accounting for emissions in the supply chain coming to just 105 tons."

In a new @nature.com study, we cross-check established academic and industry estimates with various risk factors.

We find a prudent geological CO2 storage limit that is about 10x smaller. /1
