While most of the world fixates on how to reduce the amount of carbon dioxide (CO2) and other greenhouse gases we emit into the atmosphere, scientists and engineers around the world are busy working on various “geo-engineering” technologies—many of which are highly theoretical—to mitigate global warming and its effects. One of the theories proposed for reducing global warming involves deflecting heat away from the Earth’s surface with solar shields or satellites with movable reflectors. Computer models suggest that blocking eight percent of the sun’s Earth-bound radiation would effectively counteract the warming effect of our CO2 pollution.Another technological fix involves “sequestration,” the storage of CO2 either deep underground or deep in the ocean. Some of the nation’s largest utilities, which are also “washing” coal to filter out impurities, are working on ways to capture the CO2 they emit and store it miles below the Earth’s surface.
These are only a few of many solutions that should be researched further and experimented upon.
