I'd wager anyone in that room is more qualified to be Secretary of Defence, and better understands the threat multiplier implications of climate change. Security think tanks have been thinking about it since the 1970s, & the Pentagon formally since the 1990s.

Some of the most interesting trends in electric car sales are in developing countries, here Indonesia.

When price parity is reached & energy security is a concern, EVs will take off in the developing world.

Check some charts here (mainly developed countries) robbieandrew.github.io/carsales/
Indonesia is up to 20% new car sales are EVs, in the space of a few years...

Xi Jinping announced China's new climate targets personally, a positive gesture, but the targets brought little clarity on China’s future emission pathway. Targeting a 7-10% emission reduction by 2035 from an undefined "peak level" undersells China's current clean energy boom.

I keep telling y’all that your voice and wallet are more powerful than you think, so maybe we should stop listening to the doomers and accelerationists who think things are hopeless — because things are only hopeless if we all give up.

NEW – Analysis: Clean energy just put China’s CO2 emissions into reverse for first time | @laurimyllyvirta.bsky.social

Read here: buff.ly/6eAcjRU
Line chart – China's CO2 emissions are now 1% below their March 2024 peak: China’s emissions from fossil fuels and cement, million tonnes of CO2, rolling 12-month totals. Source: Emissions are estimated from National Bureau of Statistics data on production of different fuels and cement, China Customs data on imports and exports and WIND Information data on changes in inventories, applying emissions factors from China’s latest national greenhouse gas emissions inventory and annual emissions factors per tonne of cement production until 2024. Sector breakdown of coal consumption is estimated using coal consumption data from WIND Information and electricity data from the National Energy Administration.

Just your regular reminder of where global CO2 emissions are tracking compared to scenarios that keep warming to below 1.5C in 2100, with "no or low overshoot" (maximum temperature around 1.6C).

A screenshot of a Bluesky profile for Kees van der Leun. The profile banner features a scenic landscape with a flooded field, trees, and a wooden fence leading into the water. The profile picture is a headshot of Kees van der Leun, a middle-aged man wearing glasses and a suit. His bio states that he has 38 years of experience in energy transition and is building a consultancy called Common Futures. He posts about energy, climate, and Ukraine. The bio also mentions that he is on Mastodon and clarifies that reposts are not endorsements. His handle is @sustainable2050.bsky.social, and he has 7K followers, follows 660 accounts, and has made 1.3K posts. The profile includes the hashtag #EnergySky
