Question by T.: Can someone summarize this yahoo! article?
By Mary Milliken September 13, 2006
SACRAMENTO, California (Reuters) – A leading U.S.

climate researcher said on Wednesday the world

has a 10-year window of opportunity to take decisive

action on global warming and avert a weather

catastrophe.

NASA scientist James Hansen, widely considered

the doyen of American climate researchers, said

governments must adopt an alternative scenario to

keep carbon dioxide emission growth in check and

limit the increase in global temperatures to 1 degree

Celsius (1.8 degrees Fahrenheit).
“I think we have a very brief window of opportunity to

deal with climate change … no longer than a decade,

at the most,” Hansen said at the Climate Change

Question by Michael K: Does Yahoo know about Synthetic trees? Global Warming?
Apparently, some scientist guy has come with a way to fight global warming. For Real. A scientist has invented an artificial tree designed to do the job of plants.

But the synthetic tree proposed by Dr Klaus Lackner proposes does not much resemble the leafy variety.

“It looks like a goal post with Venetian blinds,” said the Columbia University physicist, referring to his sketch at the annual AAAS meeting in Denver, Colorado.

But the synthetic tree would do the job of a real tree, he said. It would draw carbon dioxide out of the air, as plants do during photosynthesis, but retain the carbon and not release oxygen.

If done to scale, according to Dr Lackner, synthetic trees could help clean up an atmosphere grown heavy with carbon dioxide, the most abundant gas produced by humans and implicated in climate warming.
