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

These alien-looking ice sculptures formed all on their own

They look like the work of a twisted science artist. Some maniac who spent hours dreaming up nightmare shapes made of ice. But no, these monstrous and lovely ice sculptures were formed by natural processes. Here are some of the most other-worldly ice formations on Earth. » 8/22/13 3:06pm 8/22/13 3:06pm

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…

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…

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

Siberia was an unlikely haven for wildlife in the last Ice Age

Siberia enjoys a well-deserved reputation as one of the coldest places on Earth. But the last time the planet got really cold, Siberia apparently didn't go along for the ride, providing animals a warm oasis from the Ice Age. » 1/10/12 5:00pm 1/10/12 5:00pm

Sabre-tooth squirrels stalked ancient South America


Newly discovered fossilized remains from Argentina are a bizarre new species that can only be described as a "sabre-toothed squirrel". » 11/04/11 3:20pm 11/04/11 3:20pm

The Ice Age might still be going on inside China's deepest caves

Hidden in the dark caves of southwest China, a fragment of Earth's last Ice Age might well survive. Sadly, there aren't any mammoths hiding out in there, but tiny plants might represent a last link to 30,000 years ago. » 10/09/11 9:45am 10/09/11 9:45am

Where did the giant mammals of the ice age come from?

The most recent ice age was dominated by gigantic mammals like the mammoth, woolly rhinoceros, and saber-tooth cat. But there's an evolutionary mystery here. How did these animals enter the ice age already perfectly adapted for such brutally cold climates? » 9/01/11 11:26am 9/01/11 11:26am

Could iron dust stop global warming in its tracks?

The Ice Age can be explained by some well-placed specks of iron. Adding dust to the waters around Antarctica can supercharge plankton growth, causing global temperature drops. To stop climate change, we need a whole lot of iron filings. » 8/03/11 1:20pm 8/03/11 1:20pm

No, the Sun is not about to plunge us into a new Ice Age

The Sun has been unusually quiet lately, with the solar wind the slowest it's been in 50 years and the sunspot cycle reduced to nothing more than the occasional belch. But don't believe reports that this spells doom for humanity. » 6/16/11 5:00pm 6/16/11 5:00pm

There Could Be an Ice Age Two Months from Now

Everyone knows disaster movies are totally unrealistic — massive climate change doesn't just happen in a few months, right? Wrong. Some Canadian scientists have figured out that it did once, and very easily could again. » 12/02/09 9:00am 12/02/09 9:00am

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…

Strip Mining Shatters the Moon

If only the rest of 2002's The Time Machine had been like this sequence, it would have been one of the greatest science fiction movies ever. A future attempt to colonize and mine the moon instead leads to the near-total destruction of all life on Earth, as the broken moon rains chunks of rock onto Earth. Supposedly… » 2/04/08 3:00pm 2/04/08 3:00pm
