Meltwater from the ice sheet that once covered Canada has left behind clues that could help scientists predict the future of Greenland's vanishing ice

Normally rising and falling on a 13-year cycle, the lakes are at historically-low levels

Coralline algae show how Arctic sea ice has responded to climate swings on an annual scale for the past 650 years

American beech, red oak and sweet birch trees shaded Conestoga Creek. The same spot is now home to mostly box elder and sugar maple trees

An experiment that brought basalt rock to the highest pressures ever tested mimicked the conditions inside the deepest part of Earth's mantle

Globs of decomposed fish flesh recently rose from deep in the Salton Sea, coagulated into spheres on the lake surface and surfed the waves to shore, leaving the high-water line littered with thousands of sticky balls of fish

Although no earthworms are native to North America's northern forests, 15 earthworm species now live in Great Lakes forests, resulting in a loss of plant life

A mud volcano is a likely possible explanation for a new mound because Gwadar's coastline already has several of the gurgling, steamy cones

Tamu Massif dwarfs the previous record holder, Hawaii's Mauna Loa, and is only 25 percent smaller than Olympus Mons on Mars

New research suggests reconciliation between two competing theories about the prehistoric origins of carnivores

The record-breaking heat wave has been caused by A settled high-pressure system, says the National Weather Service

The combined effects of sea level rise and more powerful storms could cause a 10-fold increase in the occurrence rate of extreme storm surges, but smart planning could prevent Katrina-level destruction

Antarctica was flat, warm and crisscrossed with rivers before glaciers buzz-sawed its steep valley

A lawmaker has introduced a bill to fund a public version of an earthquake early warning system in California that's currently just in the prototype phase

New estimates of the February 8, 1843, Lesser Antilles earthquake revise its magnitude to 8.5 (from 7.8), and maps reveal that parts of Antigua subsided up to three meters

The Salton Buttes, five volcanoes at the Salton lake's southern tip, last erupted between 940 and 0 B.C., not 30,000 years ago, as previously thought, according to a new study

Materials scientists hope their computer model results will spark further research into the effects of carbon dioxide on fracturing in glaciers and ice sheets
