Firstly, Mensa, you're 95% wrong. The IPCC (http://www.ipcc.ch/) said this a few weeks ago:
The Working Group I report was published on February 2, 2007. Its key conclusions were that:
Warming of the climate system is unequivocal
Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations
Hotter temperatures and rises in sea level "would continue for centuries" no matter how much humans control their pollution, although the likely amount of temperature and sea level rise varies greatly depending on the fossil intensity of human activity during the next century (pages 13 and 18)
The probability that this is caused by natural climatic processes alone is less than 5%

Secondly, this is kinda funny:
THE US wants the world's scientists to develop technology to block sunlight as a last-ditch way to halt global warming.
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 UN report on climate change, the first part of which is due out on Friday).
...
The US response says the idea of interfering with sunlight should be included in the summary for policymakers, the prominent chapter at the front of each panel 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."
...
The US submission complains...that overall "the report tends to overstate or focus on the negative effects of climate change".
