Like the other 14 biggest earthquakes since 1900, the magnitude 8.9 event – that shook Japan and triggered tsunamis that swept the Pacific – was created by a piece of the Earth's crust shoving down into the planet's interior.
If climate change leads to ice collecting in one general area in the Arctic Ocean, it might be enough to provide a last 'refuge' for many Arctic inhabitants, including polar bears.
Glaciers' 'buzz-saw effect' can level mountains. But at high altitudes, glaciers can freeze to mountains and shield against erosion, new research suggests.
What the tragedy of the BP oil spill has taught us about regulations, technology, and how our energy diet must change.
Antarctic glacier melt is a major cause of rising sea levels. With the help of a robotic underwater vehicle, scientists have now determined why one big glacier is disappearing.
A team of scientists is climbing Indonesia's tropical glacier, Puncak Jaya, to dig out ice cores and study them for past patterns of climate change. They will also study samples from China, Peru, and Kenya.
Beneath the ice of Antarctica is a vast mountain range that rivals the Alps in its majesty.
Government and BP estimates of the amount of oil spewing into the Gulf of Mexico are too low, say scientists. Some equate the flow to one Exxon Valdez spill every five days.
