Using Lidar to Improve Earth’s Climate

A Motherboard  article reports that two separate scientists put forward proposals to use lasers to modify the Earth’s climate and fight global warming, from space.

One suggested that a satellite equipped with a high-powered laser could grow clouds in the atmosphere below; the other proposed lasers that would blast greenhouse gases from orbit to effectively erase the agents of climate change.

And European Space Agency fellow Isabelle Dicaire studies them full time. She traveled to Berlin this week to discuss how a satellite equipped with high-powered LIDAR lasers may prove useful for researching—and maybe eventually actually orchestrating—climate engineering.

It’s still in the early stages of theoretical discussions, but one can dream.
