Summer is over in the northern hemisphere, but it's been another chilling season for researchers who study Arctic sea ice.
Arctic sea ice is at the second lowest level ever. CNN's Miles O'Brien reports on its impact on wildlife and climate.
Scientists have identified new rifts on an Antarctic ice shelf that could lead to it breaking away from the Antarctic Peninsula, the European Space Agency said.
One man is kayaking the Arctic Ocean to the North Pole to highlight climate change. ITN's Phil Reay Smith reports.
Arctic Ocean sea ice has melted to the second lowest minimum since satellite observations began, according to scientists at the National Snow and Ice Data Center
There's a 50-50 chance that the North Pole will be ice-free this summer, which would be a first in recorded history, a leading ice scientist says
The North Pole may be briefly ice-free by September as global warming melts away Arctic sea ice, according to scientists from the National Snow and Ice Data Center in Boulder, Colorado.
American Morning's John Roberts talks with former British Prime Minister Tony Blair about N. Korea and the climate
From krill to king crabs, the collapse of a 160-square-mile portion of the Wilkins Ice Shelf in Antarctica could mean many changes for wildlife at the bottom of the world.
The Extreme Ice Survey founder says the crumbling ice shelf in Antarctica is proof that global warming is 'very real.'
Some 220 square miles (570 square kilometers) of ice has collapsed in Antarctica and an ice shelf about the size of Connecticut is "hanging by a thread," the British Antarctic Survey has said, blaming global warming.
Ice cover in the Arctic Ocean, long held to be an early warning of a changing climate, has shattered the all-time low record this summer, scientists say.
Ice cover in the Arctic Ocean, long held to be an early warning of a changing climate, has shattered the all-time low record this summer, according to scientists from the National Snow and Ice Data Center in Boulder.
Arctic sea ice is melting at a rate far quicker than predicted by climate change computer models and could disappear completely before the middle of the century, scientists have warned.
