Ok...ok...ya sé que ultimamente se me ha pasado un poquito la mano posteando issues ambientales pero esto está escalofriantemente interesante...
*Geoengineering- rearranging the earth's environment on a large scale to suit human needs and promote habitability.
desde...
...a plan to put into orbit small lenses that would bend sunlight away from earth — (trillions of lenses, each about two feet wide, extraordinarily thin and weighing little more than a butterfly)...
...to fertilize the sea with iron, creating vast blooms of plants that would gulp down tons of carbon dioxide and, as the plants died, drag the carbon into the abyss.
hasta...
...injecting sulfur into the stratosphere.(Injecting sunlight-scattering particles into the stratosphere appears to be a promising approach)...lacing the stratosphere with tons of sulfur dioxide. The injections, he calculated in the 80's, would require a fleet of hundreds of jumbo jets and, as a byproduct, would increase acid rain. In a draft of his paper, Dr. Crutzen estimates the annual cost of his sulfur proposal at up to $50 billion, or about 5 percent of the world's annual military spending...
Environmentalists and mainstream scientists said the focus should be on reducing greenhouse gases and preventing global warming in the first place. "Climatic engineering, such as presented here, is the only option available to rapidly reduce temperature rises" if international efforts fail to curb greenhouse gases, Dr. Crutzen wrote.
"So far," he added, "there is little reason to be optimistic."
