What Goes Down Must Go Up

Here’s a headline for the ages: Sea Ice Growing at Fastest Pace on Record:

An abnormally cool Arctic is seeing dramatic changes to ice levels.  In sharp contrast to the rapid melting seen last year, the amount of global sea ice has rebounded sharply and is now growing rapidly. The total amount of ice, which set a record low value last year, grew in October at the fastest pace since record-keeping began in 1979.

Now, of course, variations are to be expected. Variations of a year, variations of decades… In global terms, those are mere blips. That goes both ways, of course…

Nevertheless, I think it’s certainly fascinating, mainly because of the mental gyrations such evidence requires of the global warming faithful:

Bill Chapman, a researcher with the Arctic Climate Center at the University of Illinois, says the rapid increase is “no big deal”. He says that, while the Arctic has certainly been colder in recent months, the long-term decrease is still ongoing. Chapman, who predicts that sea ice will soon stop growing, sees nothing in the recent data to contradict predictions of global warming.

How in the world can the “long-term decrease” still be ongoing when it’s not, well, “ongoing”? Everything else aside, that’s just a ludicrous statement on its face. Of course:

The actual amount of ice area varies seasonally from about 16 to 23 million square kilometers. However, the mean anomaly– defined as the difference between the current area and the seasonally-adjusted average– changes much slower, and generally varies by only 2-3 million square kilometers.

That anomaly had been negative, indicating ice loss, for most of the current decade and reached a historic low in 2007. The current value is again zero, indicating an amount of ice exactly equal to the global average from 1979-2000. [Emphasis added.]

I wonder when the mainstream media will broadcast that last part?
