A not well-known fact that should be much better known: every liter gasoline burned melts 1500 kg ice long term (and >2000 kg ice when including well-to-tank, and much more when including permafrost thaw)! https://t.co/h94Qszibbg https://t.co/PdTmfTphp3 #WeDontHaveTime

[Ken Caldeira @KenCaldeira]

@DrBeatBrunner @sampenrose @ericsteig @carnegiescience @Wolsenburg Automotive facts: (650 gC / liter gasoline) x (2400 g ice / gC ) =1560 kg ice / liter gasoline

I would round that off to 1.5 m³ of ice melted per liter of gasoline burned, or about 6 tons of ice melted per gallon of gasoline burned.

@mzjacobson And probably, like with electric cars, no permanent vibrations! 😀

You may find Just Stop Oil annoying. You may dislike their tactics. But they are truth tellers, blowing the whistle on our society and government, and they do not belong in prison.

This NASA visualization shows the CO2 emitted into the earth's atmosphere + clarifies who is responsible for the climate crisis: we, the Global North.

Global surface temperatures from @BerkeleyEarth are now out for June. It was the warmest June on record for land, oceans, and the globe as a whole by a sizable margin (~0.14C), and came in at 1.6C above preindustrial levels.https://t.co/z7qNwZIuqS

Just saying.

Anyone (scientists, business people, pundits & policymakers) pushing new nuclear of any kind is misleading the public about its usefulness as a solution to climate change, air pollution, and energy security.

[Beat Brunner @DrBeatBrunner]

This 50% price drop is huge: It means electric car prices will drop below gas powered. And batteries will become standard with solar. Proof: BEV prices in China are now lower than gas-cars.

[Colin Mckerracher @colinmckerrache]

What’s going on with lithium-ion battery prices?

In short, they’re plummeting, and the implications are just starting to ripple out across the automotive and power sectors.

Great news for UK and the world! This made my day!

📣 Climate and energy expert @StarkClimate has been appointed head of our new clean power Mission Control

Tasked with turbocharging the shift from volatile fossil fuel markets to home-grown clean power by 2030

How the Nordics became world leaders in heat pumps and saw carbon emissions from heating drop dramatically.

My article for @CarbonBrief has the details 👇

Importance of this can't be overstated

First time in history a government agreed in a legal settlement to zero-out emissions

In this case, it means effectively all-electric ground, sea & inter-island air transport

Largest distributed V2G/V2X test concluded with big success in Switzerland: 50 shared cars at 40 locations, with 3 different electricity uses, many grid operators, and a yearly additional revenues possibility of $2000 per year per car. Key findings: https://t.co/F54dVyKBxE

Inondations/Flood à Morges, Switzerland: never-seen-here intensity of rainfalls: https://t.co/cwlhyg6fiz Remember: hotter air stores more humidity -> Much drier for longer, but then Much more heavy water precipitation when it rains. And it's exponential... #ClimateChange

-45% Gas for electricity within just 1 Year in California! That's the kind of speed we need and CAN achieve for #climateAction! : "In the 100 days to June 14, California saw a 45% reduction in gas-fired power output, relative to the same period a year before". #Amazing #Hope

[Mark Z. Jacobson @mzjacobson]

Gas power output nearly halves in California in one year as batteries steal the show.

@janrosenow @FMarech This is the future, available now! The grid services and days-long heat storage it provides are very interesting. The economy of scale might even compensate for the heat losses in the distribution network. Also it would make sense to distribute at lower temperatures.

[Beat Brunner @DrBeatBrunner]

This small #heatpump provides heating for 100'000 persons. Yes, it is relatively small for that job! 60 MW of heat. Previous world largest was heating 64'000 at 90°C: https://t.co/aBXEWf76Bb It also provides grid services and stores heat for days nearby! https://t.co/fU8CLAVXVf

[Jan Rosenow @janrosenow]

This is the largest heat pump in the world (60MW).

It is located in Esbjerg, DK and provides heating for 100,000 people.

The heat pump replaced coal-fired thermal generation using Denmark's electricity which is 2/3 from wind and solar.

two ipcc authors wrote a paper for kids that was peer-reviewed by some teenagers and the level of frankness is something a lot of climate scientists could learn from

[Mohamed Adow @mohadow]

The Bonn climate talks are over. My take:🧵👇🏿

Multiple factors are setting us up for a terrible shock at COP29 in Baku later this year.

This ticking disaster threatens to undermine the national climate plans (NDCs) countries will be publishing next year = 1.5C is at risk

[Mark Z. Jacobson @mzjacobson]

It should be obvious by now that new nuclear (including SMRs) is a useless (thus damaging) climate solution.

Here's a new report reinforcing this.

SMRs: Still too expensive, too slow and too risky

@JKSteinberger …it's only about their own selfish immediate interests. The only way to change those is to show that their best short-term interest is to change, or …that not changing will make them look badly in society. Eg. Putting ☀️PV on your roof will ⬆️ your 💰 and your social stand! 2/2

[Beat Brunner @DrBeatBrunner]

@JKSteinberger Thank you for what you do and for writing about the root cause of evil. My non-scientific experiences-based thought: Most people are behaving nicely and with empathy in society. But half of them only to abide to the social codes, and then, when they have to make a decision, …1/2
