...current worries over global warming. They go on to question the accuracy of today's climate models, and by extension, whether we should really be concerned about potentially catastrophic temperature increases over the coming century. They further point out that plants may indeed thrive in a future with higher carbon dioxide levels - after all, greenhouses pump in extra CO2 to encourage growth - but they fail to note that hotter summers and increasing droughts could threaten agriculture. They assert that sea levels can rise only 1.5 ft. over the coming century, ignoring the very real risk of accelerated melting...
...Philippines exploded in 1992, for instance, the SO2 sent into the atmosphere created a brief global cooling spell. Levitt and Dubner advocate pursuing this geoengineering scheme, which could potentially avert a hotter world for pennies on the dollar, compared with the long-term work of shifting to a low-carbon economy. (See pictures of the effects of global warming...
...whether the entire operation would backfire badly. Geoengineering might be a cheaper option, but followed out to at least one logical conclusion, it could be a pitfall. Say we try to use Myhrvold's giant-garden-hose scheme (after hopefully giving it a better name) without reducing carbon emissions. We could end up in a situation in which we can't abandon geoengineering without risking sudden, disastrous warming due to unchecked CO2 emissions. Then, what was meant to be a quick, cheap fix would turn out to be a trap. And while Levitt and Dubner say the fix is appealing...
...views. He says he's in favor of researching geoengineering in order to gauge its effectiveness and its potential side effects, but he still believes it should only be used, if at all, as a measure of last resort. In the meantime, we must continue to work to reduce carbon emissions over the long-term...
...That's carbon emissions, of course. As the green movement makes its way into the bedroom, low lighting is a must--to conserve electricity--but so are vegan condoms, organic lubricants and hand-cranked vibrators. (See five eco-friendly sex accessories...
