Vindication of Hansen et al.: "The rate of global warming appears to have accelerated, rising from ∼0.05°C/decade between 1880 and 1970 to ∼0.19°C/decade between 1970 and 2010, and finally to ∼0.36°C/decade between 2010 and 2024"

The acceleration may be partly related to reductions in aerosol pollutants that previously masked a portion of greenhouse gas warming (@drjamesehansen.bsky.social et al. 2025)." Rectifications by media and certain vociferous scientific voices are in order.

Mr Mann among the authors? Has he finally admitted he was wrong all along? :o

That depends on how you define "admitted".. bsky.app/profile/leon...

There seems to be a discrepancy between the science he co-authors and what he tells journalist or his social media followers.

Just make him understand the curvy part of the hockey stick.

The increase in forcing stays post-sulphur removal and forcing is still growing? And we still need to remove sulphur (and lots of ammonia).

Hmm. We have grown 850m humans who eat more meat per person and 950m new cars (<6% EV) since Paris. CO2 growth is GROWING. Radiative forcing growth is bad because it acts like a stuck accelerator pedal on heating. If it grows, °C increases will inevitably(!) accelerate. gml.noaa.gov/aggi/aggi.html
