A massive chunk of ice - larger than the city of Paris - has broken off from the Arctic's largest ice shelf because of warmer temperatures in Greenland, scientists said on Monday. The 113 sq km block broke off the Nioghalvfjerdsfjorden glacier in Northeast Greenland, which the scientists said had been expected given the rising average temperatures.
The largest hole ever observed in the ozone layer over the Arctic has closed, says Copernicus' Atmospheric Monitoring Service. Scientists spotted signs in late March of a rare hole forming and it was thought to be the result of low temperatures at the north pole.
Russia's navy said on Tuesday it had discovered five new islands revealed by melting glaciers in the remote Arctic. An expedition in August and September charted the islands, which have yet to be named and were previously hidden under glaciers, said the head of the northern fleet, Vice Admiral Alexander Moiseyev.
Canada will create a protected marine area in the country's Arctic region, where climate change is taking effect three times faster than global average, Prime Minister Justin Trudeau announced on Thursday. Glacial melting and maritime traffic are threatening multiple species off the coast of Baffin Island, in Canada's northeastern Arctic archipelago.
The first tourist train traveling through Russia's Arctic region carrying passengers heading for Norway set off from Saint Petersburg station on Wednesday with 91 passengers aboard for the inaugural trial journey.
Danish vessel setting sail from Vladivostok this week is set to become the first container ship to tackle the Arctic sea route north of Russia. The Venta Maersk, owned by Maersk Line, and carrying 3,600 containers, hopes to reach St Petersburg by late September. That could be up to 14 days faster than the southern route via the Suez Canal.
Record levels of micro-plastics have been found trapped inside sea ice floating in the Arctic. Ice cores gathered across the Arctic Ocean reveal micro-plastics at concentrations two to three times higher than previously recorded. As sea ice melts with climate change, the plastic will be released back into the water, with unknown effects on wildlife, say German scientists.
Royal Navy helicopter carrier HMS Illustrious is in the midst of NATO Exercise Cold Response, based in the Arctic.
