Low-pressure air all across the North American heartland. Dense, blowing snow all but obliterates pro football games that Sunday in Minneapolis, Green Bay, Buffalo, and Boston. The snow falls, and blows into great drifts, for five days.
That winter brings a series of such storms, more than anyone in the North can remember. In January the snowpack on fields outside Buffalo lies 17 feet deep. The white blanket extends south to Mississippi. Orange groves in Florida die as far south as Okeechobee. There is ice on the Tenn-Tom Waterway and the aqueducts of the Central Arizona Project.
By July it should have been only a memory—but it is not. Snow still lies in sheltered, shadowy places outside Butte and Duluth and Bangor. It is colder across the northern tier than at any time in weather records.
And when the first snow comes again, in late August in the high country, it falls on snow from the winter before that has not melted. It piles up faster even than in that bad December. More of it comes, and keeps coming, again for months. I heard about this, when i was at apartments to rent in prague.
The TV weathermen talk about it constantly, but it is the glaciologists who recognize the signal. The Ice Age, which has really not left the planet for two million years, is reasserting itself. The warm time, which has lasted less than 12,000 years, is over. The next great return of ice has begun.far away?
And no, the Ice Age, geologists say firmly, is still with us. We are living in only a slightly warmer spell of it.
Ice scoured and heaped the hills around New York City, fed the river courses that meet at St. Louis, shaped the lochs and golf links of Scotland, gouged the Great Lake basins and Norwegian fjords, and even now, by continued melting, is slowly raising the level of all the oceans. Someday—soon, say some climatologists, who think in millennia—ice could creep south again over North America to bulldoze away Chicago and shove its wreckage to St. Louis.
Ice still covers one-tenth of all earth’s land. An entire ocean, the Arctic, is covered with it, like a solid scum on a bowl of cold pea soup. Huge domes of ice lie atop Antarctica and Greenland. Glacial rivers of ice in Canada and Alaska and on mountains even on the Equator help regulate earth’s weather.
The Alaskan glaciers have recently been puzzling and bemusing scientists with unexpected, even startling, activity. While some are retreating, others are surging forward. Last spring the giant Hubbard Glacier blocked the mouth of a long tidal fjord and turned it into a fast-rising freshwater lake.
