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.

Scientists have previously estimated that reflecting less than 1% of sunlight back into space could compensate for the warming generated by all greenhouse gases emitted since the industrial revolution. Possible techniques include putting a giant screen into orbit, thousands of tiny, shiny balloons, or microscopic sulphate droplets pumped into the high atmosphere to mimic the cooling effects of a volcanic eruption. The IPCC draft said such ideas were "speculative, uncosted and with potential unknown side-effects".

The likely contents of the report have been an open secret since the Bush administration posted its draft copy on the internet in April. Next week's science report will say there is a 90% chance that human activity is warming the planet, and that global average temperatures will rise another 1.5C to 5.8C this century depending on emissions. The US response shows it accepts these statements, but it disagrees with a more tentative conclusion that rising temperatures have made hurricanes more powerful.

Hmph, bloody typical. Really, what they need to do is cut down emissions, not reflect sunlight back into space. The only things politicians care about is money. If one things true about governments, the best records are always the tax records.

Wow Andy. Usually after you report on Global Warming, you make jokes about alternate dimensions or stupidity being a staple of western civilization. You feeling okay?

I would never make a joke about something as serious as alternate dimensions!
