Did the Chilean Quake Shift Earth's Axis?
Pictures of widespread devastation leave no doubt: Last month's 8.8 magnitude earthquake in coastal Chile was extremely strong. Indeed, say NASA scientists, it might have shifted the axis of Earth itself.

Research shows Scandinavian conifers survived Ice Age
Until now, it was presumed that the last glacial period denuded the Scandinavian landscape of trees until a gradual return of milder weather began and melted away the ice cover some 9000 years ago. That perspective ...

Rising CO2 levels at end of Ice Age not tied to Pacific Ocean
At the end of the last Ice Age, atmospheric carbon dioxide levels rose rapidly as the planet warmed; scientists have long hypothesized that the source was CO2 released from the deep ocean.

Glacial period
A glacial period is an interval of time within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate within an ice age. The last glacial period ended about 10,000 to 15,000 years ago; the current Holocene epoch is the interglacial we are presently in.
