The US government wants the world's scientists to develop technology to block sunlight as a last-ditch effort 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 major UN report on climate change, the first part of which will be released Friday.

Washington has also attempted to steer the UN report away from conclusions that would support a new worldwide climate treaty based on binding targets to reduce emissions. The US has demanded a draft of the report be changed to emphasize the benefits of voluntary agreements and to include criticisms of the Kyoto Protocol, the existing such treaty that the Bush administration opposes.
