Hi dear ones,
Canadian and US scientists want to block the sun to cool the earth and limit global warming. Research and field-testing on what they call “geo-engineering” of the earth’s atmosphere to limit risk of climate change must begin quickly, say scientists from the University of Calgary in Canada, and the University of Michigan and Carnegie Mellon University in the US.
Studies on geo-engineering or solar radiation management (SRM) should be undertaken collectively with government funding, rather that unilaterally by nations, argue the scientists.
They say SRM would involve releasing mega-tonnes of light-scattering aerosol particles in the upper atmosphere to reduce earth’s absorption of solar energy, thereby cooling the planet.
