Reports on Geoengineering: artificially steering Earth's climate by reflecting sunlight back into space

Two reports this week by the US National Research Council look at whether humans could artificially steer Earth's climate by reflecting sunlight back into space, or by taking carbon dioxide out of the atmosphere. The twin reports– Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration and Climate Intervention: Reflecting Sunlight to Cool the Earth argue that carbon dioxide removal might have a place in a broader response plan, but sunlight-reflecting technologies are too risky.

The reports, which concluded that cutting emissions remains by far the best option, garnered wide and varied coverage in The Guardian,The Washington PostBloombergClimate ProgressScientific AmericanDot Earth blog and Nature.
