How much water in that snowpack? Scientists seek a better gauge.
More accurate, more frequent measurements of mountain snowpacks will allow water managers to mete out reservoirs with greater confidence. Two watersheds in the western US are testing grounds for a new aerial approach.

With Arctic sea ice vulnerable, summer melt season begins briskly (+video)
The Arctic saw a record loss of summer sea ice in 2012, and the 2013 melt is off to a faster start than a year ago. Another record is uncertain, but warming has sapped the ice's staying power.

Antarctic ice samples: What do they say about global warming?
Antarctic ice core samples, up to 150,000 years old, may help scientists estimate whether it will take 50 years - or 500 years - for the Ross Ice Shelf to collapse at the current rate of climate change.

Warming Arctic: Receding ice leaves Hudson Bay polar bears less time to eat
Polar bears' territorial tendencies and the diminishing ice season on Hudson Bay are conspiring to leave the animals less time to eat, researchers say. This bodes ill for their ability to reproduce, and survive.

Will ships sail through the North Pole by 2050?
Melting Arctic ice will create new sea routes, a new study says, including the potential for light ice-breakers to reach the North Pole. New Arctic shipping routes would still be seasonal rather than year-around.

Opinion Hurricane Sandy blows climate change back on the table
Today is election day in the US, but climate change should have been on the campaign agenda months ago. It shouldn't take a disaster like superstorm Sandy to finally bring it back into the conversation.

Arctic sea ice falls to record low. Global warming?
The decline in sea ice coincides with warming at the top of the world that has been occurring twice as fast there as it has for the northern hemisphere as a whole as the global climate warms.

Arctic ice shrinks to record low (+video)
Arctic sea ice has shrunk to the lowest levels since record-keeping began in 1979. Scientists say the new measurements indicate a fundamental change in the Arctic's sea ice coverage.

Antarctic Peninsula now almost as warm as 12,000 years ago
Rapid warming of the Antarctic Peninsula is bringing temperatures close to the warmth that followed the end of the last ice age, says lead researcher Richard Mulvaney, a paleoclimatologist with the British Antarctic Survey.

Arctic ice to reach record lows, say scientists
Sea ice in the Arctic Ocean is likely to hit record lows next week, and then keep on melting, according to the US National Snow and Ice Data Center.

What caused the sudden massive ice melt in Greenland? (+video)
The rapid melting of 97 percent of the surface of Greenland's ice sheet in just four days has left scientists puzzled.

Disintegrating Greenland glacier photographed from space (+video)
A NASA satellite has spotted An iceberg twice the size of Manhattan breaking away from a glacier in northern Greenland.

Militaries vie for Arctic edge as ice cap melts
By Arctic standards, the region is already buzzing with military activity, and experts believe that will increase significantly in the years ahead.

Increasing carbon dioxide levels ended the last ice age
Using data from ice cores and underwater sediment, new research shows that carbon dioxide emissions contributed to the temperature change at the end of Earth's last ice age.

Extent of Arctic summer sea ice at record low level
New data indicates the continuation of a long-term decline in summer ice underway since at least 1979. Researchers say roughly half the decline can be attributed to global warming.

Winter's freezing, so what's with Arctic sea ice?
An unusually warm January has limited the return of Arctic sea ice, whose extent set a record low for the month. The ice's ability to reflect sunlight back into space has a significant influence on climate worldwide.

Global warming: Impact of receding snow and ice surprises scientists
The seasonal cooling effect of light-reflecting snow and ice in the Northern Hemisphere may be weakening at twice the rate predicted by climate models, a new study shows, accelerating the impact of global warming.

Polar bear 'doomed'? Only if greenhouse-gas emissions aren't cut.
Greenhouse-gas emissions worldwide must be cut to avoid a disappearance of summer sea ice in the Arctic, which is crucial to the polar bear.

Russia's Putin says he wants peaceful division of Arctic
At a conference that included the US, Canada, Denmark, and Norway, Russian Prime Minister Vladimir Putin said the area should be a 'zone of peace.' But Russia is bolstering its claim to a large tract of the Arctic seabed.
