Grand problems like climate change need grand solutions. But lasers, really? That’s the proposed solution for a warming Earth from researchers at a geo-engineering conference held in Berlin this week, Brian Marchant at Motherboard reports.

A second look reveals an intriguing idea. The theory is that decreasing incoming solar energy could help decrease warning. Bright clouds in the atmosphere do reflect incoming energy from the sun, and the goal is to harness that potential. A satellite-based laser in space could use LIDAR (a technique to measure distances by sending focused light beam to the location) to find and seed new clouds.

Isabelle Dicaire, a researcher at the European Space Agency who is studying the viability of this technique, has lots to say about this possibility. Read the rest at Motherboard.
