Geo-Engineering?

Geoengineers to Start Volcano-Inspired Experiment in Risky Climate Manipulation

[Excerpted] "Two investigators are continuing down the risky path of geoengineering by readying a field experiment involving spraying chemicals into the atmosphere that would theoretically bounce sunlight back into the air to cool the Earth, the Guardian reports. But risks of geoengineering are high, and pinning hopes on a technological fix to climate change may thwart greenhouse gas reduction efforts while doing nothing to change the paradigm that created climate change.

One of the two Harvard engineers in the Fort Sumner, New Mexico, experiment is David Keith, manager of "a multimillion dollar geoengineering research fund provided by Microsoft founder Bill Gates." Their idea is to mimic the planet-cooling effect that happens when volcanoes release sulphates.

Yet many say the risks are serious and potentially disastrous.

In June scientists warned that large-scale engineering projects could reduce global rainfall by about 5 percent, and as much as 15 percent in areas of North America and Europe....
