The Economist just published a deeply-researched story about car bloat, and it's very, very damning:

"For every life that the heaviest 1% of SUVs and trucks save, there are more than a dozen lives lost in other vehicles."

Well worth your time: https://t.co/eHalcNkiBX

Green hydrogen is not a viable clean fuel. Engineers have known this for a long time, capital is waking up to this, why does the government still insist on pretending it could be?

[Daniela Gabor @DanielaGabor]

green hydrogen is a McKinsey/Germany fever dream that capital isnt buying into

[Sam Stephenson @SamStephenson_]

The lack of an attempt to replicate anything close to this in the UK remains one of our biggest failures on climate policy recently and one of the biggest opportunities for the Labour gov and their National Wealth Fund

[Thea Riofrancos @triofrancos]

This is a Green New Deal you can touch and feel, this is ecosocialism, this is green democratic industrial policy, this is feminism, this is Latin American left populism, this is a city made by and for its residents. Incredible, inspiring urbanism in Mexico City 🌿❤️‍🔥

[Cambridge for Palestine @cam4palestine]

Join us at the encampment on King's Parade to express your solidarity with Palestinians subject to a murderous campaign of ethnic cleansing, and your opposition to the University's use of your tuition fees to support the settler colonial state carrying it out.

@RicOConnell8 @ERCOT_ISO Hi, would you be able to provide a link to where this figure is from? Thanks

[Sam Stephenson @SamStephenson_]

@harry_b_smith @AukeHoekstra Maybe the end application has changed in this hype cycle but the underlying interests of prolonging fossil fuel use remains the same I would argue!

Please listen to this incredibly thoughtful answer from @AOC about voting for Biden at this moment.

Excited to be presenting my work on societal risk cascades from climate impacts under low degrees of warming at #EGU2024 today.
I’ll be in Hall X4 this afternoon, please come say hi if you’re in town

@robinsonmeyer I really enjoyed this episode but I think Koomey’s focus AI as % of electricity use is misleading.
The concern is not about AI’s final elec consumption but given constrained growth rates, how much future supply will be given over to AI when instead of using it to decarbonise

[Dr. Genevieve Guenther (she/they) 🪬 @DoctorVive]

Today @WilliamJRipple et al released the 2023 report on the terrifying state of our #climate.

It should be read by every policymaker, decisionmaker, and journalist on the planet.

Here is a thread of some key takeaways.

1/n

[Jesse D. Jenkins @JesseJenkins]

The shale gas boom is, objectively, world-changingly massive.

[Sam Stephenson @SamStephenson_]

Final (very minor) point, but if electrification is the goal then we might hope that any new electricity is used to support the shift to EVs/heat pumps, rather than displacing gas power generation

[Sam Stephenson @SamStephenson_]

Excellent piece on the implications of further delays to Hinkley Point C

[James Murray @James_BG]

Blog on 10 questions presented by the latest delays to Hinkley Point C, which is sadly a very big deal. https://t.co/0FxsCjWBK6

[Sam Stephenson @SamStephenson_]

Most of our new renewable energy this decade is already baked in. All major modelling and targets require dramatically more electricity than we are likely to have
