Why Are Sea Levels Dropping In Places Closest To The Melting Glaciers?

Our dynamic planet has an apparent paradox: the more ice melts from landlocked glaciers, the lower the sea level gets in nearby areas. How does this happen? Through the physics of isostatic rebound, when the surface of the planet acts as an elastic sheet dimpling and rebounding under changing loads. » 2/09/15 11:10am 2/09/15 11:10am

A Supermassive Ice Age May Have Led to Complex Life on Earth

There was a time on Earth, about 635 million years ago, when almost the entire planet was covered in ice. At least, this is the idea underlying the Snowball Earth Hypothesis, which holds that there was a massive ice age before the proliferation of complex, multicellular life. Though it's still controversial,… » 3/04/13 10:41am 3/04/13 10:41am

Ancient flood myths may have a basis in geological history

10,000 years ago, at a time when humans recorded historical events by telling mythical stories that got passed from one generation to the next, huge parts of the North American continent were deluged by massive walls of water. They were, as geologist David R. Montgomery writes in this month's Discover magazine,… » 9/03/12 1:49pm 9/03/12 1:49pm

How historically accurate is the new trailer for Ice Age: Continental Drift?

We sort of have a soft spot in our hearts for all the Ice Age animals. And the latest addition Ice Age: Continental Drift looks even more ridiculous than the last. Watch as the world breaks apart, separating the furry besties and creating our planet's continents. Plus, giant prehistoric crabs! Ice Age: Continental… » 3/06/12 6:20am 3/06/12 6:20am

Beasts of the Southern Wild is beautiful, operatic and filled with rampaging ice age creatures

The Beasts of the Southern Wild is very much one of the most buzzed films at Sundance right now. Everyone either loves it or respects it greatly. Whether or not this movie about a young girl facing a flood and terrible hog-monsters catches on with a wider audience remains to be seen — but I feel confident saying that… » 1/24/12 1:27pm 1/24/12 1:27pm

Global Warming May Have Prevented Super Ice Age

Click to view » 11/13/08 2:00pm 11/13/08 2:00pmSeveral thousand years from now, sheets of ice will cover most of the globe, plunging the Earth into a semi-permanent ice age. At least, that was Mother Nature’s plan. But a new study suggests that global warming caused by carbon dioxide in the Earth’s atmosphere may have staved off the most extreme ice…
