Ice age

Ice Age film Sid, a talkative sloth, is left behind by his family and the herds of mammals journeying to the south. He meets Manny, a mammoth who travels to the north, and decides to follow him. When a humans' camp is attacked by tigers, a woman takes her baby and jumps into a river and falls over a waterfall. Before she disappears, the baby is rescued by Manny and Sid.

As temperatures drop in areas adjacent to these ice cliffs, cold-weather plant life is driven to southern latitudes. Meanwhile, the dramatic drop in sea levels enables rivers to carve out deeper valleys and produce enormous inland lakes, with previously submerged land bridges appearing between continents.

Upon retreating during warmer periods, the glaciers leave behind scattered ridges of sediment and fill basins with melted water to create new lakes.

Approximately a dozen major glaciations have occurred over the past 1 million years, the largest of which peakedyears ago and lasted for 50, years. At the height of the recent glaciation, Ice age ice grew to more than 12, feet thick as sheets spread across Canada, Scandinavia, Russia and South America.

Corresponding sea levels plunged more than feet, while global temperatures dipped around 10 degrees Fahrenheit on average and up to 40 degrees in some areas.

In North America, the region of the Gulf Coast states was dotted with the pine forests and prairie grasses that are today associated with the northern states and Canada. The origins of ice age theory began hundreds of years ago, when Europeans noted that glaciers in the Alps had shrunk, but its popularization is credited to 19th century Swiss geologist Louis Agassiz.

Contradicting the belief that a wide-ranging flood killed off such megafauna as the wooly mammoth, Agassiz pointed to rock striations and sediment piles as evidence of glacier activity from a destructive global winter. Geologists soon found evidence of plant life between glacial sediment, and by the close of the century the theory of multiple global winters had been established.

A second important figure in the development of these studies was Serbian mathematician Milutin Milankovitch. Along with solar radiation levels, it is believed that global warming and cooling is connected to plate tectonic activity.

One significant outcome of the recent ice age was the development of Homo sapiens.

Humans adapted to the harsh climate by developing such tools as the bone needle to sew warm clothing, and used the land bridges to spread to new regions. By the start of the warmer Holocene epoch, humans were in position to take advantage of the favorable conditions by developing agricultural and domestication techniques.

Meanwhile, the mastodons, saber-toothed cats, giant ground sloths and other megafauna that reigned during the glacial period went extinct by its end.

The reasons for the disappearance of these giants, from human hunting to disease, are among the ice age mysteries that have yet to be fully explained.In Africa, drought continues for the sixth consecutive year, adding terribly to the toll of famine victims.

Ice age

A mere 15, years ago during the Ice Age, much of North America lay under a huge glacier. Mammoths, saber tooth cats and cave lions roamed the earth!

Some of the best evidence of this glacier is found in Wisconsin such as the state’s many lakes, river valleys, gently rolling hills, and ridges. The Ice Age: Causes and Consequences. The Ice Age has been a longstanding problem for uniformitarian thinking, with many unsolved mysteries. No mere tweaking of today's climate conditions would cause such a catastrophe.
