...scenarios for global warming, for example, invoke a speedup in the hydrological cycle by which water evaporates and then comes down as rain. The cooling produced by solar dimming, however, may slow the rate of evaporation, while higher up in the atmosphere the pollutants responsible for absorbing and reflecting sunlight are likely to interfere with the process that produces rain...
...fourth Qualia product is out now, and while it's the only nonpersonal tech item of the bunch, it's the most innovative. The $30,000 projector features the highest screen resolution available for TV and movie watching, and a high-powered xenon lamp that mimics sunlight...
Clouds, which reflect sunlight, ought to cool the earth. But they can also hold in warmth. That second effect swamps the first. According to Minnis' calculations, increased cloud cover since the 1970s ought to have led to a warming of .36° to .54°F per decade. The actual warming during this period falls within that range, at just under .5°. That may not sound like much, but when only 9°F separate our current temperature from the last Ice Age, it's clear that a little warming makes a big difference. "This study," says Minnis, "demonstrates that contrails should...
...solar power powered the microphones, amps and speakers of the main stage in Harvard Yard from University President Lawrence H. Summers’ opening speech at 11:30 a.m. to the end of the festivities at 5 p.m. The project, called “Rolling Sunlight,” is a collaboration among Greenpeace Clean Energy Now!, the FAS Resource Efficiency Program (REP) and the Climate Campaign. These solar panels have made appearances up and down the Northeast coast this spring, stopping at Middlebury College in Vermont the day before coming to Harvard and rolling on to Bowdoin in Maine...
William W. Parish, director of the Climate Campaign, said that this solar battery could power an average American home for four to five days, even without receiving any sunlight. Parish, a Yale undergraduate, also praised Harvard?...
