AUGUST 1, 2021
Sprinkling powered basalt over natural ecosystems would remove vast amounts of carbon dioxide from the Earth’s atmosphere while also improving soils. But even in best case scenarios for renewable energy and industrial decarbonization, it looks certain that significant carbon dioxide emissions will continue for decades.

The Science Behind Sea Level Rise: How Past Emissions Will Shape Our Future
