"Relatively low cost" plan would cool the Earth's poles by 2 °CCurated byNew Atlas
New research suggests that cooling the poles by 2 °C (3.6 °F), and re-freezing the Arctic and Antarctic, is "feasible at relatively low cost with conventional technologies," using Stratospheric Aerosol Injection (SAI) of heat-reflective particles focused on the poles. The side effects could be nasty, and the politics near-impossible, but the plan offers a way to slow, or reverse the catastrophic sea level rise projected as polar ice collapses.
ATACAMA DESERT, Chile — In the middle of the desert in northern Chile, massive pools of Caribbean blue water sit next to what appear to be snowdrifts. But this is a lithium mine. The pools are filled with salty groundwater that contains lithium. It's a key component in the rechargeable lithium-ion …
