Sea level will rise fast even if we limit global warming to 1.5°C

Satellite data shows the ice sheets are melting faster than expected and slowing sea level rise to a manageable rate would require lowering the global temperature

Conventional "non-nuclear" world war will cannibalize current rates. Once the war is over "nuclear summer" from an aerosol-loss perspective will finish whats left with unprecedented warming.

BAU will be no more ... nor will we.

What are microplastics doing to your brain? We’re starting to find out

The average human brain contains around 7 grams of plastic, but it’s unclear how this affects us. Now animal studies are revealing links to poor cognition
