Latest Ice ages Stories
Dust trapped deep in Antarctic ice sheets is helping scientists unravel details of past climate change.
An article published in the prestigious science magazine Nature Geoscience yesterday shows that the period towards the end of the ice age was engraved by extreme and short-lived variations, which finally terminated the ice age.
Scientists are now making an alarming claim that the earth is on the brink of entering another Ice Age that could last the next 100,000 years.
The common wisdom is that the invention of the steam engine and the advent of the coal-fueled industrial age marked the beginning of human influence on global climate.

During the Ice Ages, animals in Antarctica faced conditions even more life-threatening. Massively thick and permanent ice covered most of the land, and sea-ice coverage around the continent was permanent.
Just a few years ago, the world's climate scientists predicted that Greenland wouldn't have much impact at all on sea level in the coming decades. But recent measurements show that Greenland's ice cap is melting much faster than expected.
