We just released a new free dataset with highlights from our World Energy Balances. Designed for policy makers & energy experts, it offers insights into how energy flows have evolved over the decades, with insights covering 60+ countries & regions 👉 iea.li/3VWHFJX

Unlike the 1970s oil crises, countries now have a cheaper alternative to imported fossil fuels 🔌⚡ Putting electrification at the centre of #COP31 means reducing vulnerability to fossil price shocks. Learn how clean power delivers energy independence: ember-energy.org/lat...

RCP8.5 was never a prophecy; it was the “burn baby burn” pathway. Renewables got cheap, so RCP8.5 is now implausible. Current policy still points near ~3°C, just a smaller disaster. Hopefully 3°C soon looks as implausible as RCP8.5. Maybe even thx to an orange in charge who drives up fossil prices.

"Before mass leaders seize the power to fit reality to their lies, their propaganda is marked by its extreme contempt for facts as such, for in their opinion fact depends entirely on the power of man who can fabricate it" - Hannah Arendt, the origin of totalitarism

This bluesky space becomes enjoyable. Just posted my probably last ever 'X'... An entry into the competition for best Tesla bumper stickers, now that he is full throttle for fossil fuels and everything else Trump stands for. LET HIM GO TO MARS.

After net zero CO2 emissions do you want to halt or continue global warming? If you want to halt global warming, the point of getting to net zero emissions, then we better define it correctly! The key is how “removals” are defined & the role humans play. doi.org/10.1038/s415... 1/

A new paper led by Sebastian Sippel just appeared in Nature arguing that ocean temperature measurements in the early 20th century have a cold bias. It's a fun story illustrating the process of scientific discovery, so let me talk about it a bit. 🧵 www.nature.com/articles/s41...

Early-twentieth-century cold bias in ocean surface temperature observations - Nature

Independent statistical reconstructions of the global mean surface temperature from either ocean or land data show that existing estimates of early-twentieth-century ocean surface temperatures are too...

Understanding the consequences of potential overshoot above the 1.5°C warming level has been the focus of the PROVIDE project and the work by a great group of interdisciplinary authors has just been published in @natureportfolio.bsky.social www.nature.com/articles/s41... Here’s what we found: 1/

Overconfidence in climate overshoot - Nature

Aiming for declining global temperatures can limit long-term climate risks compared with a mere stabilization of global warming, including sea-level rise and cryosphere changes.

'Great success' of small modular reactors: Magnox produces weapons grade plutonium in North Korea. Other plans burn through cash. Relaxing that one doesn't have to argue any more on grounds of risks, waste, nuclear proliferation, etc. Economis sort it out. reneweconomy.com.au/small-modula...

Small modular nuclear reactors: a history of failure

Dozens of ‘small modular reactor’ designs are being promoted, but precious few will reach construction stage and likelihood of SMRs being built in large numbers is negligible.
