As we look up the south side of zero, here in God's own Dakotas, we might consider Robert Samuelson's hard truths about global warming: we can't do an damn thing about it. This is not something Nancy Pelosi will tell you. But it's true.
The dirty secret about global warming is this: We have no solution. About 80 percent of the world's energy comes from fossil fuels (coal, oil, natural gas), the main sources of man-made greenhouse gases. Energy use sustains economic growth, which -- in all modern societies -- buttresses political and social stability. Until we can replace fossil fuels, or find practical ways to capture their emissions, governments will not sanction the deep energy cuts that would truly affect global warming.
Considering this reality, you should treat the pious exhortations to "do something'' with skepticism, disbelief or contempt. These pronouncements are (take your pick) naive, self-interested, misinformed, stupid or dishonest. Politicians mainly want to be seen as reducing global warming when they're not.
