Here is an interesting article in the Missoulian .

Is it possible that technology will save the day with the problem of climate change just as the internal combustion engine solved the problem of what to do with the massive amount of horse manure back at the beginning of the twentieth century?

This is something I never even conceived of before reading this article.

I'll excerpt some of this article to illustrate my point.

On the technology side, there are many ways to confront that temperature change. Keith said one involves spraying sulfur compounds into the upper atmosphere, shielding the sunlight the same way a big volcanic blast like the Mount Pinatubo eruption did in 1991.

"The climate reaction to cooling is pretty damn fast," Keith said. "It responds in about a year. Nature's tried it."

And it's pretty cheap. Estimates range from $100 billion to as little as $100 million. That's the difference between less than one-fifth what the U.S. armed forces spent this year (on the high end) or 5 percent of the Montana state budget (on the low end)
