Climate change: Can we even do it? Should we even try?

<div>Global warming and the resulting droughts help make climate manipulation a hotly debated issue.</div> <p>” /><br /><b>The Massachusetts Institute of Technology has long been known worldwide for its engineering programs, and a symposium at MIT this week will draw scientists from around the globe to focus on a hot facet of the field — climate engineering.</b></p> <p>Creating an artificial cloud cover, or modifying clouds to reflect light back into space, is one of them. But probably the more popular climate engineering technology now involves pumping sulfates into the atmosphere to block the sun’s rays and cool temperatures, similar to what happens in volcanic eruptions. “In 1830, the first national meteorologist of the U.S., James Espy, proposed making artificial volcanoes of his own. So whether it’s weather or climate, this manipulation has been proposed and, in some cases attempted, for a very long time,” Fleming said. Weather manipulation or modification can be traced to the 1940s and ’50s, with a process called cloud seeding. In cloud seeding, many chemicals — including dry ice and silver iodide — were tried to produce rain or snow. In fact, author Kurt Vonnegut’s brother, Bernie Vonnegut, invented silver iodide when he worked at General Electric in the 1950s. The Chinese and Russians have bragged about having weather-modifying technology for years. “The Chinese have been claiming to have brought good weather to the Olympics for their parades. And the mayor of Moscow just said he was going to stop all snow in the city for the whole winter, but he didn’t get a good response from the suburbs,” Fleming said. MIT’s Layzer thinks climate engineering will create new problems that will need their own solutions. “The idea of taking a symptom of global warming, which is heat, and trying to mitigate that symptom seems to me to be just another form of parceling a large and comprehensive problem into bits and pieces, which will in turn need solutions.” Layzer also sees it this way: “Climate engineering is just another example of treating a symptom. Treating problems in a piecemeal way, actually you just move the problem from one place to another. If you take pollution out of the air, you still have it. You have to put it somewhere, so you put it in the water. Then you’ve polluted the water.” All these issues will come up for discussion at the MIT symposium Friday. Fleming sums up the symposium as a chance perhaps to learn what might not work, in addition to what might. “Tinkering with the planet is dangerous,” he said. “The lessons would be very similar to those learned in the weather control experiments. It would be very difficult to measure and it might have incredible inadvertent and unwelcome side effects.” </p></p> <div class='yarpp yarpp-related yarpp-related-website yarpp-template-list'> <!-- YARPP List --> <p>Related posts:</p><ol> <li><a href=International day of demonstrations on climate change
