WASHINGTON — The president's new science adviser said Wednesday that global warming is so dire, the Obama administration is discussing radical technologies to cool Earth's air.
John Holdren told The Associated Press in his first interview since being confirmed last month that the idea of geoengineering the climate is being discussed.
One such extreme option includes shooting pollution particles into the upper atmosphere to reflect the sun's rays. Holdren said such an experimental measure would only be used as a last resort.
"It's got to be looked at," he said. "We don't have the luxury of taking any approach off the table."

Holdren outlined several "tipping points" involving global warming that could be fast approaching.
Once such milestones are reached, such as complete loss of summer sea ice in the Arctic, it increases chances of "really intolerable consequences," he said.
Twice in a half-hour interview, Holdren compared global warming to being "in a car with bad brakes driving toward a cliff in the fog."
At first, Holdren characterized the potential need to technologically tinker with the climate as just his personal view. However, he went on to say he has raised it in administration discussions.
Holdren, a 65-year-old physicist, is far from alone in taking geoengineering more seriously.
The National Academy of Science is making climate tinkering the subject of its first workshop in its new multidiscipline climate challenges program.
The British parliament has also discussed the idea.
The American Meteorological Society is crafting a policy statement on geoengineering that says "it is prudent to consider geoengineering's potential, to understand its limits and to avoid rash deployment."
Last week, Princeton scientist Robert Socolow told the National Academy that geoengineering should be an available option in case climate worsens dramatically.

But Holdren noted that shooting particles into the air — making an artificial volcano as one Nobel laureate has suggested — could have grave side effects and would not completely solve all the problems from soaring greenhouse gas emissions.
So such actions could not be taken lightly, he said.
Still, "we might get desperate enough to want to use it," he added.
Another geoengineering option he mentioned was the use of so-called artificial trees to suck carbon dioxide — the chief human-caused greenhouse gas — out of the air and store it.
At first that seemed prohibitively expensive, but a re-examination of the approach shows it might be less costly, he said.
cliffnotes: some people are stupid as hell
p.s. this wasnt intended to be an anti-obama thread, rather a people are stupid/global warming crap gone to far thread.

Sending pollutants into the higher atmospheres sounds incredibly unpredictable, imo.
Then again this is coming from a guy that got a B in Meteorology his junior year in high school.
But on the other hand, that was the class I had during lunch/study hall, so I would be absent a lot. -
this is borderline retardation
