We could spray the atmosphere with particles that reflect sunlight or fertilize algae to grow and take up more CO2. We could release minerals that react with CO2or capture the gas directly from the air. These are some of ...

A trio of researchers, two with Pacific Northwest National Laboratory and the other the California Institute of Technology, developed computer simulations suggesting that using geoengineering to cool the planet would not ...
How can the world combat the continued rise in global temperatures? How about shading the Earth from a portion of the sun's heat by injecting the stratosphere with reflective aerosols? After all, volcanoes do essentially ...

Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun's radiation back into space and cool the planet. But could this effect be intentionally recreated to fight climate change? A new ...
