climate change; global warming; geoengineering

Reducing Greenhouse Gas (GHG) emissions is the primary climate change mitigation approach. Scientists are looking at technological approaches for capturing and removing carbon from the atmosphere in hopes of some day reversing global warming.

Three news articles published in the same week explore the controversial science of geoengineering to mitigate global warming. These pieces look at the concept of altering the earth’s skies to better reflect solar heat before it is trapped in the atmosphere. The articles highlight a number of experiments underway or being considered.
