Other methods include spraying seawater mist from ships toward low-lying clouds, which would then reflect more sunlight. Another more extreme but oft-discussed option would involve putting mirrors into the earth's orbit. If those ideas have the disadvantage of sounding convoluted, they have the real advantage of being cheap - at least in relative terms. According to the new paper by Lane and J. Eric Bickel of the University of Texas, the seawater-mist method could counteract a century's worth of warming for $9 billion. Compare that to the political complexity and the economic unknowns associated with...
...turn down the thermostat would be to spread sulfur particles into the atmosphere, either through artillery or with airplanes, thickening the air enough so that it would bounce some sunlight back. We know that process does reduce global temperatures: when Mt. Pinatubo in the Philippines erupted in 1991, it threw millions of tons of sulfur dioxide into the atmosphere, causing global temperatures over the following months to drop by nearly 1°F. Geoengineering would work much the same way - only it would need to be done continuously, to keep up with the intensifying greenhouse effect...
...woke up—an hour later than planned. I ran with hair flying and reporter notebook pages as askew as my rumpled skirt, dashing through the metro tunnels out into the (possibly) blinding sunlight. I knew all about the dangers of “solar maculopathy” and was determined to not make eye contact with my subject—and usually, archnemesis—the sun. A hotline had been established in Hong Kong for the symptoms of eye damage—blurred vision, holes in visual field, afterimages, and reddened perception. Most people didn?...
...contributed nothing less than A Sunday on La Grande Jatte, a tour de force of early modern art. Properly dazzled, a good number of the Twenty became converts to Seurat's pointillism. This was too much for Ensor. He had already dismissed the Impressionists. Who cared about capturing fugitive sunlight when you could be trying to pin down hellfire? Seurat's shimmering neo-Impressionism looked no better to him. What Ensor wanted was an art that could reach into his interior life, which must have been quite a place, or serve his feverish critique of his times...
Cloud cover is only one element of climate sensitivity. Scientists are also concerned about the earth's ice, which reflects sunlight back into space, making it a cooling factor, while seawater absorbs the sun's heat. That means that as polar sea ice melts because of warming, leaving more open water, the warming process could accelerate - which would then melt more ice. There are also concerns that as the permafrost in the Arctic thaws, it could release massive amounts of methane, a powerful greenhouse gas that would further accelerate warming...
