Giant space sunshade proposed to help fight climate change

Original: How a giant space sunshade can help ‘solve’ climate change

A proposal for a giant space sunshade — a large structure placed between Earth and the Sun to block a fraction of sunlight — is being discussed as a way to reduce global temperatures and complement efforts against climate change. The idea, sometimes called solar geoengineering, remains speculative and would face enormous engineering, cost and governance challenges, but it is drawing attention as global warming concerns grow.

Why now: Rising concern over climate change is driving interest in radical technological fixes like space-based solar shields.
