Making a bad system (offsetting) more efficient makes things worse… and here the unintended effect of validating fungibility between carbon and albedo is disastrous (as it risks legimating substitution of solar geoengineering for emissions cuts)!

Letting Silicon Valley Geoengineer the Atmosphere Will End Badly We already have plenty of evidence of what happens when things better left to governments β€” which in this case might decide to never flip the switch at all β€” are ceded to private industry.

I can't emphasize this too much. Scientists who may be well intentioned and favor solar geoengineering research because "it's just research" and do not approve of deployment will not be the ones who decide whether to deploy whatever ... www.gravityisgone.com/letting-sili...

Can AI Slash Pollution? Fossil Fuel Industry Is Investing in Boosting Oil Production, Profits Instead DeSmog reveals that Big Oil says they’re using AI to produce more fossil fuels, while utilities are exploring how β€œAI agents” could take over key power grid functions.

This is a really good @desmog.com post on this topic btw, featuring a bunch of friendly norwegian fossil fuel people

Thanks for highlighting the source. Nature should be ashamed to publish this hype-ridden excuse for analysis. The first test of any evaluation of AI is if it defines what it includes in that term. This fails…

Democrats and climate groups β€˜too polite’ in fight against β€˜malevolent’ fossil fuel giants, says key senator Sheldon Whitehouse of Rhode Island gives 300th climate speech on the US Senate floor

Strong analysis, but still hoping that impacts will stimulate action. Unfortunately everything so far suggests that growing impacts exacerbate denial to the point that systems are too broken to take action… we need a narrative of social and ecological repair www.theguardian.com/us-news/2025...

Study looking at AI chatbots in 7,000 workplaces finds 'no significant impact on earnings or recorded hours in any occupation' Despite AI’s promise to revolutionize white-collar work, most workers are using it sparinglyβ€”or hiding it from their boss.

AI doesn’t help you work less or get paid more, but does destroy the environment and climate.

Having said that, funding CDR development through offsets is a fool’s errand, resulting directly in mitigation deterrence, and sustaining counterproductive market ideologies in climate policy.

Not quite. Removal offsets could exist only for genuinely impossible to abate emissions. At the same time, taking net-zero seriously, with all possible-to-abate emissions eliminated, there could be no avoidance offsets (as no one would have further cuts they could make to generate credits).

β€œThere is extreme danger in launching such field trials into an environment with neither national nor international governance in place.” But well governed research into geoengineering risks would be wise. The key question is why so many SRM advocates resist effective governance for research?

It was always a mistake to try to sell CDR by promising it could decarbonize oil. People who want oil don't really care whether it's decarbonized or not.

Only a real climate politics β€” the one that actually phases out fossil fuels β€” will deliver carbon removal, expensive and challenging as it is.

When I wrote in a novel, some years ago, β€˜We live in the light that comes to us’ that carried within it, for me, the idea that sometimes there is very little, sometimes there is mostly darkness.

It is still our time, we do what we can.
