Hacking Global Warming

If we’re in the beginning stages of a major shift in global temperature — as many suggest we are — what can we do about it? Eli Kintisch suggests that scientists may have to attempt some radical fixes to address the problem. Whether it’s putting more pollutants into the air to keep Earth’s temperature down to covering polar ice with reflective panels to cut down on melting, he thinks something’s got to be done. “The only thing crazier than geoengineering is what we’re doing now to the atmosphere by continuing to dump carbon dioxide into it,” Kintisch is quoted as saying.
