Scientists Propose Space Sunshade to Combat Global Warming

The ambitious project aims to cool the Earth by 1.5 degrees Celsius but faces significant technical and financial challenges.

A team of climate scientists proposes deploying a giant sunshade in space to block a portion of the sun's radiation, aiming to cool the Earth by 1.5 degrees Celsius.
The proposed sunshade would need to be roughly the size of Argentina and would involve launching smaller shades to create a diffused effect.
The project, led by Dr. Yoram Rozen of the Technion-Israel Institute of Technology, is still in the predesign phase but could launch a prototype within three years with sufficient funding.
Critics argue the sunshade could be astronomically expensive and vulnerable to damage from solar storms or space debris, potentially causing rapid warming if destroyed.
Supporters believe the sunshade could stabilize the climate while other mitigation strategies are pursued, emphasizing the need for a multifaceted approach to addressing climate change.
