Climate Engineering is a Controversial "Plan B" for Global Warming

Mar 19, 2014

Can we engineer Earth's atmosphere to stop global warming?

The 1991 eruption of Mount Pinatubo in the Philippines blanketed the Earth with a haze of sulfur dioxide that temporarily cooled global temperatures by one degree Fahrenheit. Some scientists now see the intentional injection of sulfur dioxide into the stratosphere as a potentially cheap and easy way to counteract global warming. Others warn of potentially deadly unintended consequences.
