How solar geoengineering could cool the planet

  • 6 years ago
THE STRATOSPHERE — Solar geoengineering specialists reckon technology could cool the planet's temperature by using it to sulfur to the atmosphere.

Volcanic eruptions can cool the earth. This is because they emit sulfur dioxide, a UV repellent gas, into the stratosphere.

Earther reports that millions of high-altitude balloons carrying sulfur may also be an option. Another option, according to Earther, maybe to use aircraft such as the stratotanker to disperse the sulfur into the stratosphere, as the aircraft can already reach the required altitude. That altitude is around 6 miles from the earth's surface.

Citing a leaked UN draft report on global warming, Reuters reports the organization's climate experts opined that solar geoengineering could be "economically, socially and institutionally infeasible."

Harvard's solar engineering head Gert Wagner told Earther that deployment of solar radiation management tech would be "unambiguous proof of our miserable failure as a species to act as responsible planetary stewards."
