I don't think so.  Economic activity isn't going to stop.   This isn't the 
1930's.  Yet.  People will still be driving, heating their homes and factories 
will still be operating.  If anything, the collapse of the Monopoly Game Ponzi 
scheme formerly known as Wall Street will hamper efforts to reign in emissions. 
 And that's something else we can't afford.

Economic woes may give planet a breather
NICOSIA (Reuters) - A slowdown in the world economy may give the planet a 
breather from the excessively high carbon dioxide (CO2) emissions responsible 
for climate change, a Nobel Prize winning scientist said on Tuesday. 
Atmospheric scientist Paul J Crutzen, who has in the past floated the 
possibility of blitzing the stratosphere with sulfur particles to cool the 
earth, said clouds gathering over the world economy could ease the Earth's 
environmental burden.

NICOSIA (Reuters) - A slowdown in the world economy may give the planet a 
breather from the excessively high carbon dioxide (CO2) emissions responsible 
for climate change, a Nobel Prize winning scientist said on Tuesday.

Atmospheric scientist Paul J Crutzen, who has in the past floated the 
possibility of blitzing the stratosphere with sulfur particles to cool the 
earth, said clouds gathering over the world economy could ease the earth's 
environmental burden.

Slower economic growth worldwide could help slow growth of carbon dioxide 
emissions and trigger more careful use of energy resources, though the global 
economic turmoil may also divert focus from efforts to counter climate change, 
said Crutzen, winner of the 1995 Nobel Prize in Chemistry for his work on the 
depletion of the ozone layer.

"It's a cruel thing to say ... but if we are looking at a slowdown in the 
economy, there will be less fossil fuels burning, so for the climate it could 
be an advantage," Crutzen told Reuters in an interview.

"We could have a much slower increase of CO2 emissions in the atmosphere ... 
people will start saving (on energy use) ... but things may get worse if there 
is less money available for research and that would be serious."

CO2 emissions, released by the burning of fossil fuels in power stations, 
factories, homes and vehicles, are growing at almost 3.0 percent a year.

The U.N. Panel on Climate Change estimates that world temperatures may rise by 
between 1.8 and 4.0 degrees Celsius (3.2-7.2 degrees Fahrenheit) this century. 
The Group of Eight industrial nations agreed in July to a goal of halving world 
emissions by 2050.

Crutzen was in Cyprus for a lecture organized by the Cyprus Institute, a 
research foundation.

He caused a stir with the publication of a paper in 2006 suggesting that 
injecting the common pollutant sulfur into the stratosphere some 10 miles above 
the earth could snuff out the greenhouse effect.

He believes that dispersing 1 million tons of sulfur into the stratosphere each 
year, either on balloons or in rockets, would deflect sunlight and cool the 
planet.

Scientists observed that world temperatures dropped by 0.5 degrees centigrade 
on average when Mount Pinatubo in the Philippines erupted in 1991, spewing 
sulfur dioxide into the atmosphere, and Crutzen said the idea originated with a 
Russian scientist about 30 years ago.

"I am not saying we should do it, but it is one of the options if we continue 
under present conditions. We should study it," he said. "If you look beyond a 
decade, two decades, and nothing has been done (to counter warming) then we 
will have a very serious problem on our hands."

Sulfur is a component of acid rain, which has harmful effects on plants and 
fish.

"Acid rain is caused by sulfur dioxide emissions from the ground, from the 
chimneys, and it's 50 million tons per year. The experiment in the stratosphere 
would be one million tons of sulfur per year. It's negligible," he said.

It would be an extreme endeavor, but for extreme circumstances, he said.

In a 2007 report, the U.N. climate change panel said such geo-engineering 
options were largely speculative and unproven, with the risk of unknown side 
effects. Reliable cost estimates had not been published, it said.

"The price is not a major factor... it's peanuts," said Crutzen. "The cost has 
been estimated by some at 10, 20 million U.S. dollars a year."
