A monument to Britons who lost their lives for science in Antarctica has been unveiled on the waterfront in Stanley, Falkland Islands

Passage to change

For years, explorers sought the Northwest Passage through Arctic waters. Last year, what had previously been a geographical impossibility was finally achieved
‘Antarctica’s environmental measures must be strengthened, as more scientists visit the region and tourist numbers increase,’ says Professor Steven Chown from Australia’s Monash University
Antarctica’s sea ice is now mapped in 3D after scientists from the UK, US and Australia used an underwater robot to explore areas that were previously too difficult to access
Historic data from NASA aircraft, ice buoys and former Soviet ice floe bases have been used to establish that snow has thinned on Arctic sea ice since the 1950s
An international team of scientists has created the most accurate and precise reconstruction to date of lead pollution over Antarctica
Ice fronts were far more advanced around the Arctic during the early 19th century than they are today, according to a new analysis of whalers’ log books
A warming period that took place more than 400,000 years ago resulted in a nearly complete deglaciation of southern Greenland, raising global sea levels by about five metres, according to a new study
The Antarctic ice sheet is losing 159 billion tonnes of ice a year – twice as much as when it was last surveyed – a new study has found
An international team of scientists has discovered an ancient tundra landscape preserved under the Greenland Ice Sheet
A new study has found that six massive glaciers in West Antarctica are moving more rapidly than they did 40 years ago, resulting in an increased discharge of ice into the ocean
The last remaining stable region of the Greenland ice sheet is no longer stable, according to a new study published in Nature Climate Change

A continent in pieces

Temperatures are rising rapidly in parts of Antarctica, but the overall picture of the way in which the frozen continent and its inhabitants are responding to climate change is still incomplete

A clear signal

With the summer ice melting and temperatures rising at unprecedented rates, scientists are all but certain that changes taking place in the Arctic can be attributed to anthropogenic climate change
Melting of West Antarctica’s ice cap is causing its bedrock to shift sideways, according to a new study
Climate-change related alterations to the Earth’s rotation are causing the position of the North Pole to shift, according to a new study
Average summer temperatures experienced by the eastern Canadian Arctic during the past century are higher than they have been at any time over the past 44,000 years, and perhaps as long ago as 120,000 years
Deep water in the Greenland Sea is warming about ten times more rapidly than the global ocean, according to a new study
