WASHINGTON -- The ozone hole over Antarctica is markedly smaller this year than in the last few years and has split in two, government scientists reported today.

This year's improvement was attributed to warmer than normal temperatures around the edge of the polar vortex, or circular wind pattern that forms annually in the stratosphere over Antarctica, according to Paul Newman, a lead ozone researcher at NASA's Goddard Space Flight Center in Greenbelt, Md.

Global warming could actually lead to a big chill in some parts of the world. If the atmosphere continues to warm, it could soon trigger a dramatic and abrupt cooling throughout the North Atlantic region?where, not incidentally, some 60 percent of the world's economy is based.
...
Average winter temperatures could drop by 5 degrees Fahrenheit over much of the United States, and by 10 degrees in the northeastern United States and in Europe. That?s enough to send mountain glaciers advancing down from the Alps. To freeze rivers and harbors and bind North Atlantic shipping lanes in ice. To disrupt the operation of ground and air transportation. To cause energy needs to soar exponentially. To force wholesale changes in agricultural practices and fisheries. To change the way we feed our populations. In short, the world, and the world economy, would be drastically different.
