The melt season across the Arctic is getting longer by five days per decade, according to new research from a team including Prof Julienne Stroeve (Professor of Polar Observation and Modelling at UCL Earth Sciences).
Measurements from ESA’s CryoSat satellite show that the volume of Arctic sea ice has significantly increased this autumn.
The melting of sea ice in the Arctic is well on its way toward its annual "minimum," that time when the floating ice cap covers less of the Arctic Ocean than at any other period during the year.
Last October's Superstorm Sandy was made far worse by the melting of Arctic sea ice, new research suggests.
In support of their views, climate change skeptics have long pointed to the fact that Antarctic sea ice - unlike that in the Arctic - is actually growing.
The blanket of sea ice floating atop the Arctic Ocean has melted to its lowest extent ever recorded - since satellites began measuring it in 1979, to be exact.
Melting sea ice and global atmospheric warming are making the Arctic warm as much as four times faster than the global average, Australian scientists say.
As Arctic sea ice melts through global warming, Americans can expect - paradoxically - to see more severe winter weather.
NASA scientists have detected large releases of methane - a highly potent greenhouse gas - from the crumbling Arctic sea ice.
Arctic sea ice has reached its second-lowest level since satellite observations began over 30 years ago, scierntists at the University of Colorado Boulder's National Snow and Ice Data Center say.
Warming oceans are triggering an enormous movement of marine species, say scientists, and could threaten North Atlantic fishing stocks.
Arctic sea ice concentration was at its second-lowest ever in March, according to data from NASA.
The water flowing from the North Atlantic into the Arctic Ocean is the warmest it's been in 2,000 years, say scientists.
The loss of Arctic sea ice could lead to species such as polar bears and some types of seal and whale being lost through hybridization.
Geologists have found evidence that ice covered the whole world 716.5 million years ago.
