Why Don't We Live On A White Earth?

In the early days of climatology, a disturbing possibility reared its head whenever people ran computer models of Earth's climate — suddenly, everything would freeze over. It's called the White Earth climate, and this is why it hasn't happened. » 3/31/14 6:40am 3/31/14 6:40am

There is a scientific reason why it always rains on weekends

If you are in the northeastern United States, it's likely that your weekend traffic makes it rain on Saturday and Sunday. In fact, most of us help control the weather in some way. Here's how you are making the sun shine, or bringing on a thunderstorm. » 3/10/14 11:14am 3/10/14 11:14am

It's official: Arctic sea ice levels have reached a record low

Sea ice levels shrink every summer, but this year has been different. Yesterday brought some big news: the extent of Arctic sea ice has officially reached a record low. What's more, it's done so weeks earlier than ever before — and it's not done shrinking yet. » 8/27/12 7:00am 8/27/12 7:00am

Witness a glacier's staggering seven-year retreat

Since 2004, glaciologist William Pfeffer has been photographing Alaska's Columbia Glacier. By monitoring where the glacier ends and the waters of Prince William Sound begin, Pfeffer is working to understand how coastal ice sheets contribute to rising ocean levels. Now, by piecing his photographs together, Pfeffer… » 4/27/12 11:45am 4/27/12 11:45am

The ocean depths might be hiding the full extent of global climate…

The last decade was the hottest on record, and yet it wasn't until 2010 that an individual year was hotter than the record-breaking 1998 heatwave. Somehow, global temperatures mysteriously flattened out. The explanation may lie thousands of feet underwater. » 9/19/11 11:00am 9/19/11 11:00am

Just 12 million years ago, there were forests on Antarctica

It's hard to imagine, but about 55 million years ago, Antarctica was ice-free and full of lush forests. Now analysis of ancient pollen has revealed when the last Antarctic vegetation died out...and what's next for the continents's vast ice sheets. » 6/28/11 1:45pm 6/28/11 1:45pm

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

Climate change has guided 2,500 years of European history

Climate has been the secret driver of history, particularly in the preindustrial world. Empires and kingdoms rose to power when it was warm and wet and toppled when it became cool and dry...and climate might not be done guiding history. » 1/13/11 1:10pm 1/13/11 1:10pm

Global warming could mean a golden age for tropical rain forests

Climate change could have devastating consequences for much of the world's ecosystems, but at least one area might benefit. Ancient rain forests thrived during severe warming millions of years ago, helping to create today's species diversity. » 11/12/10 11:20am 11/12/10 11:20am

A computer that can predict hurricanes up to ten years in advance

Currently, we're only able to predict the next year in hurricanes with any accuracy. But a new system that incorporates 35 years worth of hurricane data has found patterns that could predict hurricanes a decade in advance. » 11/08/10 2:17pm 11/08/10 2:17pm

A waterpocalypse in Earth's southern hemisphere?

Evapotranspiration, the movement of water from the Earth's surface to the atmosphere, has been steadily decreasing in the southern hemisphere. What's causing this unprecedented moisture shortage, and how will it affect people down under? » 10/11/10 10:43am 10/11/10 10:43am

New evidence that it was once possible to sail across Antarctica

Why are two groups of tiny sea creatures called bryozoans nearly identical, despite being separated by 1,500 miles of ice? They must have traveled across the continent long ago - on a massive Antarctic seaway. » 8/31/10 7:30am 8/31/10 7:30am

Earth's climate could naturally jump 10 to 15 degrees - and there's no…

We're unsure how humans might affect the climate long-term, but it's certain that nature alone can produce sudden, extreme climatic shifts. New findings suggest these abrupt changes might be completely unpredictable. » 8/30/10 10:44am 8/30/10 10:44am
