At a Smaller Dose, Solar Geoengineering Could beAnthropocene

  A new study published in Nature Climate Change says that might also be true with solar geoengineering if we want to avoid its potential side effects.

  Solar geoengineering involves spraying the atmosphere with tiny particles that reflect sunlight back from earth to bring down temperatures.

  The new study, however, finds that if we halve global warming by using just the right amount of geoengineering, it would not aggravate extreme temperatures or precipitation.

  Many previous geoengineering studies have analyzed using the technique to offset all greenhouse gas-induced warming to cool the Earth back to pre-industrial temperatures.

  For one, it simulates the effects of solar geoengineering by simply reducing the amount of solar radiation that reach the Earth’s surface.
