No Quick Or Easy Technological Fix For Climate Change, Researchers Say
ScienceDaily (Dec. 27, 2008)-Global warming, some have argued, can be reversed with a large-scale “geoengineering” fix, such as having a giant blimp spray liquefied sulfur dioxide in the stratosphere or building tens of millions of chemical filter systems in the atmosphere to filter out carbon dioxide.
But Richard Turco, a professor in the UCLA Department of Atmospheric and Oceanic Sciences and a member and founding director of UCLA’s Institute of the Environment, sees no evidence that such technological alterations of the climate system would be as quick or easy as their proponents claim and says many of them wouldn’t work at all.
