Lomborg and his many flaws

A new book by Bjorn Lomborg is making the rounds. He's a major apologist for the global warming deniers.

Glib, misleading associations mark Lomborg's style. In his chapter on glaciers, he states that since "we're leaving the Little Ice Age" (which, in fact, we left long ago) it's not surprising that glaciers are dwindling. Remarkably, he believes that is more good news, because "with glacial melting, rivers actually increase their water contents, especially in the summer, providing more water to many of the poorest people in the world." "It boils down to a stark choice," he lectures us. "Would we rather have more water available or less?"

Lomborg's flawed grasp of climate science is most evident when he discusses sea levels. He makes much of the 2007 Intergovernmental Panel on Climate Change's (IPCC) projection that sea level will rise by "about a foot," misleadingly noting that this is lower than previous projections. He does not tell us that the IPCC figures do not account for collapsing ice sheets, which may result in far larger rises, due to the difficulty of predicting how glacial ice will react to warming.

While Lomborg waves vaguely in the direction of ice melt and collapse, he assures us it's not a problem. We'll just put up dikes. Indeed, with dikes, he asserts, some nations might end up with more land than they have today. And so the arguments go on, from rising seas to extreme weather events to malaria and other tropical diseases, the collapse of the Gulf Stream, food shortages and water shortages. In one case after another, Lomborg asserts, it's cheaper and better to do nothing immediately to combat climate change, but instead to invest in other things.
