Cool it on global warming

Bjorn Lomborg in the Washington Post

All eyes are on Greenland's melting glaciers as alarm about global warming spreads. This year, delegations of U.S. and European politicians have made pilgrimages to the fastest-moving glacier at Ilulissat, where they declare that they see climate change unfolding before their eyes.

Curiously, something that's rarely mentioned is that temperatures in Greenland were higher in 1941 than they are today.

Or that melt rates around Ilulissat were faster in the early part of the past century, according to a new study. And while the delegations first fly into Kangerlussuaq, about 100 miles to the south, they all change planes to go straight to Ilulissat -- perhaps because the Kangerlussuaq glacier is inconveniently growing.

Spending a huge amount for very little.

Environmental groups say that the only way to deal with the effects of global warming is to make drastic cuts in carbon emissions -- a project that will cost the world trillions (the Kyoto Protocol alone would cost $180 billion annually). The research I've done over the last decade, beginning with my first book, "The Skeptical Environmentalist," has convinced me that this approach is unsound; it means spending an awful lot to achieve very little. Instead, we should be thinking creatively and pragmatically about how we could combat the much larger challenges facing our planet.
