Bill Gates, the Incompetent Bungler Who Gave You the Bug-Infested Windows OS, Demands That You Give Him the Power... to Dim the Sun

From Ace:

The guy who had to buy an operating system from someone, and who has not been able to work out of the bugs in it after 50 years, just wants the power to seed the atmosphere with reflective particles to reduce the strength of the sunlight reaching the earth.  

No big deal. Bill Gates can definitely be trusted to, oh, not subject the entire earth to the Blue Screen of (Reduced Sunlight) death. 

Bill Gates, among others, is backing the Harvard Stratospheric Controlled Perturbation Experiment. 

The SCoPEx is researching a form of "geoengineering" to prevent global warming. In this case, they're exploring the idea of spraying tiny particles into the air to reflect sunlight and make the earth cooler. Towards that end, Harvard scientists are planning to fly a balloon full of equipment 12 miles above Sweden next year to gather data.
