With a mixed-results at COP30 - i.e. good intentions but no concrete plans for the “transition away from fossil fuels” - don’t give up.
Let’s remember the progress made since the Paris Agreement and the options ahead of us. That’s the message of the image below

This protocol is the result of a big community effort to coordinate how reduced-complexity / simple climate models are benchmarked, constrained, and evaluated for the IPCC AR7 cycle.
It introduces expanded idealised + scenario experiments, strong carbon-cycle focus, and alignment with CMIP7.

1/2. “The COP of Truth cannot ignore science. 75% of carbon emissions come from fossil fuels. Today we are not even allowed to discuss pathways for a just and equitable transition away from fossil fuels.” Colombia at the close of #COP30.

We've had Battery Tenders around 1910 already, but nonetheless a very cool concept for long distances without overhead lines.

Temperature Update for October 2025
Third warmest October in the instrumental record.
Similar conditions to September.
A weak La Niña returns in the Pacific.
2025 is very likely to be the 3rd warmest year.

Something for the causal folks ...
We estimated the share of scientists who believe that "advances in technology will largely solve the problems caused by climate change" and used causally informed Bayesian regression models to estimate the impact of techno-optimism on scientists' civic actions and high-impact lifestyle changes.
