The Ice Is Melting

A report issued by NASA this week concludes the rate of ice loss in the cryosphere is continuing to accelerate:
Between 1.5 trillion and 2 trillion tons of ice in Greenland, Antarctica and Alaska have melted at an accelerating rate since 2003, according to NASA scientists, in the latest signs of what they say is global warming. NASA’s Gravity Recovery and Climate Experiment, or GRACE, mission uses two orbiting satellites to measure the “mass balance” of a glacier, or the net annual difference between ice accumulation and ice loss.

When ice melts, the surrounding air or water cools down, basic thermodynamics. It would be ironic if that cooler air and water from excess northern melt were to work their way south a little farther and a little earlier in the season than they otherwise would have, and maybe even help fuel an occasional localized snow or ice storm, which right-wing climate change skeptics, especially those bearing a borderline pathological obsession with Al Gore, would then seize on as evidence that global warming is … well not sure exactly. Somewhere vaguely between massive inexcusable scientific error and fraud, to an infinitely scalable global conspiracy between a tightly woven cabal of nations who can’t agree on something as scientifically basic as what units of measurement to use for a common lug nut. And the wingers will do it, apparently, without a care or thought in the world of the difference between the NASA GISS 125 year global average temperature trend and related volumes of empirical data Vs. cherry picking poor comparisons or the sprinkling of snow they had on their drive way last Tuesday morning.
