Deshielo

Señores, se derrite Groenlandia. A construir casas con zancos y aprovechar todas las liquidaciones de salvavidas.

En fin, yo no aprendo más. Es una cuestión de fe:

House Speaker Nancy Pelosi recently returned from a junket to Greenland, where, among other things, she says she "saw firsthand evidence that climate change is a reality." True enough, Madame Speaker, but you didn't see.

New satellites tell us that Greenland -- mainly southern Greenland -- is shedding ice at the rate of 25 cubic miles per year. If Greenland lost most of its ice, sea levels would rise 20 feet or so. Greenland is by far the largest mass of ice in the Northern Hemisphere, with roughly 10 percent of the world's total.

Greenland's total ice volume is 680,000 cubic miles, and it is losing four ten–thousandths of its ice per year. Do the math. That works out to 0.4 percent of its total mass per century.

Never mind that the most recent study of Greenland indicates that even this minuscule rate may have slowed. Pelosi is falling victim to the common misconception that a slight, additional warming of Greenland will lead to the biblical flood, pronto.

That's the horror–show scenario driving the hysteria. How well does it stack up against the facts?
