Arctic sea ice this summer shrank to its second lowest level since scientists started to monitor it by satellite, with scientists saying it is another ominous signal of global warming.
The Arctic region is warming up at twice the rate as the rest of the planet, and the most obvious symptom of this warming is the retreat of the sea ice that covers the Arctic Ocean.
Polar bears are losing life-sustaining sea ice crucial for hunting, resting and breeding in all 19 regions of the Arctic they inhabit, a study warned on Wednesday.
Historic changes to Antarctic sea ice could be unravelled using a new technique pioneered by scientists at Plymouth University.
Severe hurricanes, storm surges and an increase in the number of icebergs are just some of the changes planet Earth has experienced due to warming oceans over the last 20 years, according to a new report.
