When "global warming" is involved.
A sane person would think that warmer temperatures of late in the Arctic (1) minus colder temperatures in the northern hemisphere generally (1) would cancel each other out (0) and put "the planet is ever-warming" argument on ever-shakier ground.
But not in global warming land. To the strange inhabitants therein warmer weather up north actually causes colder weather here. Thus 1-1=2.
Think I'm kidding?
Today's belch from the loony warmists:
Holiday Blizzard: More Signs of Global WarmingNow, you're saying to yourself: Can't the opposite be true as well? Maybe cold temperatures in New York are causing warmer temperatures at the North Pole. That we're experiencing global cooling.

One theory is that a warmer Arctic may actually lead to colder and snowier winters in the northern mid-latitudes. Even as countries like Britain — suffering through the coldest December on record — deal with low temperatures and unusual snow, the Arctic has kept on warming, with Greenland and Arctic Canada experiencing the hottest year on record. Temperatures in that region have been 5.4°F to 7.2°F (3°C to 4°C) above normal in 2010. As a result, the Arctic sea-ice cover has continued to shrink; this September, the minimum summer sea-ice extent was more than 770,000 sq. mi. (2 million sq km) below the long-term average, and the third-smallest on record. Snow may be piling up in midtown Manhattan, but the Arctic is continuing its long-term meltdown.

This is their latest excuse for weather patterns not fitting their mold and they're sticking to it.
You have to admit, it's a creative ditty. Warmth causes cold. Someone had to be drunk when they dreamt that one up.
