I'm so tired of this sales pitch: "AI is using a lot of energy but it's also helping the climate". The AI that helps the climate is generally very different from the AI that uses a lot of energy (e.g. LLMs like ChatGPT). We can have the former without the latter.

The blackout in Spain and Portugal wasn’t just a grid failure. It was a test of resilience, trust, and truth. Resilience isn’t about avoiding disruption. It’s about building the physical and societal systems, grids and information alike, that help us thrive through it. New on Illuminem 👇

More than 160 financial institutions joined the Glasgow Financial Alliance for Net Zero (GFANZ) in 2021, signaling commitment to climate action. But just two years later, the Net-Zero Banking Alliance (NZBA) an offshoot of GFANZ, has lost every major U.S. bank in a single month.

LA is burning and our political baseline remains unchanged, climate policies are acceptable only if they demand zero sacrifice or lifestyle change This is a profoundly irrational economic decision. The longer we wait, the greater the loss of opportunity and the higher the costs we’ll face

Mary Robinson, the former UN envoy summed up the result well: “cop29 came very close to failure and it has ended with a disappointing deal. But it is a deal the world can build on in 2025.” Trust is at a low ebb. COP30 🇧🇷 was always going to be key but its workload has now doubled

The latest climate finance text is out at COP29 $500bn, maybe $600bn, felt like where things would end up. Somewhere between actual needs and the current state of play. Not ideal but something all parties could sell back home $300bn is an insult, no other word for it #ClimateAction
