The Arctic is heating up quickly, but scientists say polar geoengineering is 'unrealistic' and 'dangerous' | CBC News
For years, scientists have been toying with the idea of artificially modifying the climate through geoengineering — especially in the Arctic, which is warming four times as fast as the rest of the world. The main proposals include artificially thickening sea ice, fertilizing the ocean with iron and releasing sunlight-reflecting particles into the atmosphere to reduce the sun's warming effect. Though the feasibility of these ideas was always questionable, researchers are now saying in a new study t...
