Video: CNBC: Why Bill Gates Is Funding Solar Geoengineering Research
"Fires burning across the Amazon rainforest have renewed the debate about solutions to climate change. Bill Gates is backing the first high-altitude experiment of one radical approach called solar geoengineering. It's meant to mimic the effects of a giant volcanic eruption. Thousands of planes would fly at high altitudes, spraying millions of tons of particles around the planet to create a massive chemical cloud that would cool the surface. [...] The technology is not far from being ready and it's affordable, but it could cause massive changes in regional weather patterns and eradicate blue sky. [...]Watch the video to learn how it would work and hear the debate around the ethics and efficacy of solar geoengineering."
