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:

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:

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

Earth Was a Fungal World Before Plants Existed
Fungi arose long before plants, shaping Earth with early soils and nutrient cycles. Their hidden legacy shows they may have prepared the world for life to flourish on land.

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. 🧪 (graphic by

This is not a new approach; it dates back to psychiatric research conducted in the 1960s, when LSD was investigated for its potential in treating anxiety and end-of-life distress.
