"Obama looks at climate engineering"

This reminds me of the suggestions during the 1970s that coal dust be spread over the polar ice caps to help cause them to melt. Of course, back then the concern was a new global ice age.

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. . . . . .

Among the solutions proposed during the mid1970s when the fear of global cooling was all the rage are these.

A survey completed last year by Dr. Murray Mitchell of the National Oceanic and Atmospheric Administration reveals a drop of half a degree in average ground temperatures in the Northern Hemisphere between 1945 and 1968. According to George Kukla of Columbia University, satellite photos indicated a sudden, large increase in Northern Hemisphere snow cover in the winter of 1971-72. And a study released last month by two NOAA scientists notes that the amount of sunshine reaching the ground in the continental U.S. diminished by 1.3% between 1964 and 1972. . . .

such as melting the Arctic ice cap by covering it with black soot or diverting arctic rivers

Yes, we are as dumb as you think we were. Please accept our apologies for creating a giant air conditioner instead of curing cancer (or whatever the free market would have done).

He's out of his mind. The sun is in a slump, not seen since the Dalton Minimum 200 years ago. It looks like we're going toward another mini-ice age. Those morons from NASA, especially Jim Hansen, is intent on suiciding the population, or what? Global cooling is vastly more deadly than global warming.
