Demis Hassabis on our AI future: ‘It’ll be 10 times bigger than the Industrial Revolution – and maybe 10 times faster’ The head of Google’s DeepMind says artificial intelligence could usher in an era of ‘incredible productivity’ and ‘radical abundance’. But who will it benefit? And why does he wish the tech giants had...

Dude has some magic beans for you.

“the energy required is going to be a lot for AI systems, but the amount we’re going to get back, even just narrowly for climate [solutions] from these models, it’s going to far outweigh the energy costs.”

Our new manuscript on global #wildfires look beyond burned areas and ask:
What drives the #economic damages of wildfires — now & in the future?
We find that socioeconomic vulnerability, not just #climate, is key.

Column | As Gaza starves, Israel’s far right sees a dream coming true Members of Israel’s government embrace the Trump-inspired vision of a Gaza of gleaming towers, ritzy tourism and pristine neighborhoods, but without Palestinians.

I normally post on climate science, which is my expertise.
But this is too important to look away, so I want to share this from the Washington Post. Please read.

Heat kills, more than we think and we can see. Heat intensified by climate change kills even more. For the 1st time, we conducted a rapid impact attribution study looking at the additional deaths that occurred due to climate change across 12 cities in Europe, in close to real-time: shorturl.at/mv6ms

bar chart showing deaths associate with extreme heat with and without climate change in 12 European cities

About 1500 of the approx. 2300 people that will have lost their lives across 12 European cities last week would still live, if it wasn't for our burning of oil, coal and gas. If we care about the right to life, we need to stop burning fossil fuels. www.imperial.ac.uk/grantham/pub...

Die Klimakrise kann nur gemeinsam bewältigt werden. Ländern, die ungleich viele Emissionen ausgestoßen haben und es immer noch tun, so wie Deutschland, kommt dabei eine besondere Verantwortung zu. Mit irreführenden Aussagen im deutschen Bundestag werden wir dieser sicher nicht gerecht. /end

Cumulative CO₂ emissions Running sum of CO₂ emissions produced from fossil fuels and industry since the first year of recording, measured in tonnes. Land-use change is not included.

Es gibt dazu natürlich noch deutlich mehr zu sagen. Wir betrachten zB. nur Emissionen von 2020 bis zur Treibhausgasneutralität, nicht die über 90 Mrd. Tonnen historischen Emissionen seit 1850. Unsere Verantwortung als historischer Emittent wiegt schwer. 7/

Mit unserer Ende-zu-Ende Attributionsmethode berechnen wir den Einfluss auf die Frequenz von extremen Hitzemonaten (vorindustrielle 1-in-100 Jahresereignisse). Die Zunahme ist relativ zur vorindustriellen Wahrscheinlichkeit angegeben. 7/

Daraus schätzen wir den globalen Erwärmungsbeitrag mittels TCRE ab (das ist niedrig gegriffen, da diese Methode die kurzfristige Erwärmungswirkung von Methan unterschätzt). 6/

Details zur Methode: Basierend auf Ariadne Szenarien haben wir ein Budget von 8,2 Mrd. Tonnen CO2äq für 2020-2045 angenommen.
ariadneprojekt.de/media/2025/0...
Wir gehen von Deutschlands Klimaneutralitätsziel aus. 5/

Ergebnis: Deutschlands Emissionen von 2020 bis 2045 werden die Wahrscheinlichkeit für extreme Hitzemonate (vorindustrielle 1-in-100 Jahresereignisse) in vulnerablen Regionen um 15-30% erhöhen. Die Aussage, dass “keine einzige Naturkatastrophe weniger geschehen würde”, ist nicht korrekt.

Jede Tonne CO2 Emissionen trägt zur Erwärmung bei. Deutschland stößt jährlich noch über eine halbe Milliarde Tonnen aus. Um es mit dem @ipcc.bsky.social zu sagen: “Every bit of warming matters, every year matters, every choice matters” www.ipcc.ch/sr15/about/f...

In der Generaldebatte im Bundestag sprach Bundeskanzler Friedrich #Merz auch zum Klimaschutz. Er sagte:
"Selbst wenn wir alle morgen klimaneutral wären, würde keine einzige Naturkatastrophe weniger geschehen". Ein Faktencheck.

Heatwaves may cut GDP by 0.5 pct points in Europe, Allianz says Allianz Research compared a day with temperatures above 32 degrees Celsius to half a day of strikes.

Report from Allianz Research shows a day with temperatures above 32 degrees Celsius in 2025 has a comparable effect on GDP as half a day of strikes.

Recent heatwaves across Europe could slow economic growth in Europe by half a percentage point.

Overshoot Conference from 30 September to 2 October 2025 As the world faces the growing risk of exceeding the 1.5°C warming threshold, understanding the risks and responses to climate overshoot across different disciplines has never been more urgent.

🚨Submission deadline ahead🚨

Join us for the world's first global conference at @iiasa.ac.at from Sep 30 to Oct 02.

(Extended) abstract deadline is around the corner (July 4). Don't miss it!

Scientific advice for the determination of an EU-wide 2040 climate target and a greenhouse gas budget for 2030–2050

Dem EUSABCC folgend müsste die EU Emissionsreduktionen im Ausland *zusätzlich* zu den territorialen Reduktionen unterstützen. Eine Aufweichung des 90% Ziels steht im Widerspruch zur wissenschaftlichen Analyse. climate-advisory-board.europa.eu/reports-and-...

Sehr lesenswerte Kurzanalyse zur @ec.europa.eu für das 2040 Reduktionsziel der Europäischen Union. Die AutorInnen sehen Auslagerung von Emissionsreduktion zur Erreichung des 90% Reduktionsziels als unvereinbar mit dem EU-Klimagesetz an.

The pursuit of 1.5°C endures as a legal and ethical imperative in a changing world As the world nears 1.5°C of global warming, near-term emissions reductions and adequate adaptation become ever more important to ensure a safe and livable planet for present and future generations

What becomes of the 1.5°C goal now that global warming is approaching that level?🌍🔥🌡️

In a new @science.org Policy Forum we explain how the 1.5°C goal remains a critical legal & ethical benchmark, even as the world nears and may soon exceed 1.5°C of global warming🧵1/

⚠️Global warming caused by humans is advancing at 0.27°C per decade – the highest rate since records began.

The Day the Mountains Won How a Peruvian farmer sued a German coal giant and helped create a legal blueprint to hold fossil producers accountable for climate harms.

A couple weeks ago much of the international press got a really significant climate ruling utterly, completely wrong. @roycerk2.bsky.social got the story right for @drilledmedia.bsky.social drilled.media/news/Peru-RWE

Causal pathway from AMOC to Southern Amazon rainforest indicates stabilising interaction between two climate tipping elements - IOPscience Causal pathway from AMOC to Southern Amazon rainforest indicates stabilising interaction between two climate tipping elements, Högner, Annika, Di Capua, Giorgia, Donges, Jonathan F, Donner, Reik V, Feulner, Georg, Wunderling, Nico

New study out, in which we detect a causal link in reanalysis+observational data from an AMOC SST index to the Southern Amazon rainforest: dry season precipitation increases when the AMOC weakens.

Interesting reaction from the NZ prime minister to our letter:

‘He said it was lovely there were "worthies" who wanted to send him letters, but academics "might want to direct their focus and their letters to other countries"’

www.rnz.co.nz/news/nationa...

The EU is discussing its 2040 target that needs to sketch a credible path towards achieving its mid-century "climate neutrality" target (net zero greenhouse gas emissions).

Lots of interests pull in all directions, but our scientific advice from the independent @esabcc.bsky.social is clear

Call for abstracts – now open! As the world edges closer to surpassing the 1.5°C global warming threshold, it's time to confront the risks of climate overshoot.

Countries cleaning up more climate pollution than they are producing?

That is the idea behind achieving net-negative emissions.

Though an ambition for the far future, its pursuit starts with deep emissions cuts over the next decade.
