Cheney's Solution to Global Warming

It's been covered here before. It's Big Science about to go awry in a very big way, fitting for Big Time himself. Since they don't want to stop the profitable process causing global warming, they figure, why not quench the only source of warmth in the world?

This idea is so bad I don't know where to begin:

The US government wants the world's scientists to develop technology to block sunlight as a last-ditch way to halt global warming, the Guardian has learned. It says research into techniques such as giant mirrors in space or reflective dust pumped into the atmosphere would be "important insurance" against rising emissions, and has lobbied for such a strategy to be recommended by a major UN report on climate change, the first part of which will be published on Friday.

The US has also attempted to steer the UN report, prepared by the Intergovernmental Panel on Climate Change (IPCC), away from conclusions that would support a new worldwide climate treaty based on binding targets to reduce emissions - as sought by Tony Blair. It has demanded a draft of the report be changed to emphasise the benefits of voluntary agreements and to include criticisms of the Kyoto Protocol, the existing treaty which the US administration opposes.

The final IPCC report, written by experts from across the world, will underpin international negotiations to devise a new emissions treaty to succeed Kyoto, the first phase of which expires in 2012. World governments were given a draft of the report last year and invited to comment.

The US response, a copy of which has been obtained by the Guardian, says the idea of interfering with sunlight should be included in the summary for policymakers, the prominent chapter at the front of each IPCC report. It says: "Modifying solar radiance may be an important strategy if mitigation of emissions fails. Doing the R&D to estimate the consequences of applying such a strategy is important insurance that should be taken out. This is a very important possibility that should be considered."

Why does every solution these guys come up with involve more destruction of the natural world?

Why is it this seems likely to lower the possibility of ever using the Sun as an alternate energy source?

And finally, why does this seem just the kind of answer a Dark Lord would choose?
