Today's Antarctic region once as hot as California, Florida
Parts of ancient Antarctica were as warm as today's California coast, and polar regions of the southern Pacific Ocean registered 21st-century Florida heat, according to scientists using a new way to measure ...
Researchers find temperature feedback magnifying climate warming in Arctic
Earth orbit changes key to Antarctic warming that ended last ice age
For more than a century scientists have known that Earth's ice ages are caused by the wobbling of the planet's orbit, which changes its orientation to the sun and affects the amount of sunlight reaching higher ...
New satellite data on melting of Himalayan glaciers
Warming ocean layers will undermine polar ice sheets
Warming of the ocean's subsurface layers will melt underwater portions of the Greenland and Antarctic ice sheets faster than previously thought, according to new University of Arizona-led research. Such melting ...
Strange Martian Spirals Explained
Almost 40 years ago, NASA's Mariner 9 spacecraft relayed to Earth the first video images of Mars' northern polar ice cap, revealing a strange pattern of spiral swirls that has puzzled scientists ever since. ...
Planetary scientists solve 40-year-old mysteries of Mars' northern ice cap
Scientists have reconstructed the formation of two curious features in the northern ice cap of Mars—a chasm larger than the Grand Canyon and a series of spiral troughs—solving a pair of mysteries dating ...
Radar Finds Ice Deposits at Moon's North Pole
(PhysOrg.com) -- Using data from a NASA radar that flew aboard India's Chandrayaan-1 spacecraft, scientists have detected ice deposits near the moon's north pole. NASA's Mini-SAR instrument, a lightweight, ...
Previously Unknown Volcanic Eruption Helped Trigger Cold Decade
(PhysOrg.com) -- A team of chemists from the U.S. and France has found compelling evidence of a previously undocumented large volcanic eruption that occurred exactly 200 years ago, in 1809.
On a tropical island, fossils reveal the past—and possible future—of polar ice
The balmy islands of Seychelles couldn't feel farther from Antarctica, but their fossil corals could reveal much about the fate of polar ice sheets.
US tidal floods will be 'chronic' in 15 yrs, study claims
Many US coastal communities already struggle with flooding at high tides, a problem that will become "chronic" in the coming 15 years due to global warming, scientists said Wednesday.
Study links polar vortex chills to melting sea ice
A new study says that as the world gets warmer, parts of North America, Europe and Asia could see more frequent and stronger visits of cold air as the world gets warmer.
Video from polar bear's neck cam shows life on ice
The first video of life on Arctic sea ice from a polar bear point of view has been released by the U.S. Geological Survey.
New research sheds light on history of polar current
Research conducted by a team that included scientists from British Antarctic Survey reveals the ocean current moving around the South Pole flowed at much the same speed in the last ice age as it has done ...
