1,600+ fossil fuel lobbyists at COP30, outnumbering every delegation except Brazil
This isn’t ‘dialogue’; it’s the industry responsible for the crisis hijacking the negotiations meant to stop it
If this doesn’t make you furious, you’re not paying attention

Climate modeling suggests that if the Earth warms by 3 °C by the late 21st century, hurricane-induced power outages will increase significantly in northern Florida, Georgia, the mid-Atlantic, and the North Atlantic coast. In PNAS: https://ow.ly/Lu7I50Xgj05

Episodic carbonate cementation in a Miocene Eger Rift paleolake was driven by a combination of climatic, hydrological, and biogeochemical factors, including increased humidity, weathering, and variable solute fluxes.

The buildings of the future might also be giant batteries. Improved electron-conducting carbon concrete can bear weight and store energy. A key to performance is the nanoscale connectivity of the electrode’s conductive carbon network. In PNAS: https://ow.ly/7rZa50XaBiC

News that shocks no one: Carbon offsets do nothing for climate.
Carbon offsets fail to cut global heating due to ‘intractable’ systemic problems, study says
Analysis of 25 years of evidence shows most schemes are poor quality and fail to lower emissions

Congratulations, you've just lived through the three hottest summers on record 🫠
But with greenhouse gas emissions still piling up in the atmosphere, those records probably won't stand for terribly long. 🧪
