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 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. 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, which the US opposes.
The final report, written by experts from across the world, will underpin international negotiations to devise an 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 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."
Scientists have previously estimated that reflecting less than 1 per cent 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 sulfate 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 US submission complains the draft report is "Kyoto-centric" and it wants to include the work of economists who have reported "the degree to which the Kyoto framework is found wanting".
It also complains that overall "the report tends to overstate or focus on the negative effects of climate change". It also wants more emphasis on responsibilities of the developing world.
But Professor Stephen Schneider, a climate consultant to the US government for more than 30 years and a key figure in the panel process for more than a decade, says the world is "playing Russian roulette" with its future by responding too slowly to climate change.
The panel's draft report shows projections for average global temperature rise from 1990 to 2100 will expand slightly, with a new range of one to 6.3 degrees. The 2001 report's range was 1.4 to 5.8 degrees.
Professor Schneider said he was concerned the increase was more likely to be three degrees or higher, with a 10 per cent chance of a six-degree rise by the end of the century.
"Hell, we buy fire insurance based on a 1 per cent chance," he said. "If we're going to be risk averse … we cannot dismiss the possibility of potentially catastrophic outliers and that includes Greenland and West Antarctica [ice sheets breaking up], massive species extinctions, intensified hurricanes and all those things. "There's at least a 10 per cent chance of that. And that to me for a society is too high a risk … My value judgement when you're talking about planetary life support systems is that 10 per cent, my God, that's Russian roulette with a Luger."
Can they acheive a geosynchronous orbit over Iran? N. Korea? Massachusetts?
I had to stop reading!
They are working on how to induce global warming? We actually have the technology to induce an ice age? COOL!!! We are this close to actually be able to "play" God.
And we thought nuclear weapons in the hands of dictator tyrants was dangerous!!!????
I was thinking about the Law of Unintended Consequences...
This reminds me of how I do risk assessment. There are three factors:
1. What is the likelyhood of a thing happening.
2. What is the impact of the thing happening.
3. What does it cost to ensure prevention.
Based on the answers to the above questions, I believe the proper course of action is to do nothing.
Will they enact the Montgomery Burns solution from the Simpsons or the Captain Chaos solution from South Park?
Most of these foks are so technologically savy that they will buy this as a solution!
They could always put a magnifying lens in place of the mirrored lens and scorch the earth. That might raise the temperature a bit (too much).
They all think they can do a better job than God (the original designer).
Where's Michael Moore?
It must be Bill Gates.
He hates seeing Sun trading
near six and a half . . .
Me too.
A giant pair of shades?
I hope they do what I did, my wife keeps changing the thermostat so I put another one elsewhere hidden hooked up to the heater and left the old one as a dummy, otherwise the women on earth will keep complaining its eather too hot or too cold.
We can just use some deep earth penetrator on all the active volcanoes... that should fix everything right up!
That's what the book/mini series was about. Getting what you asked for, but not what you wanted variation on the Law of Unintended Consequences.
