The cold waters of the planet’s north are highly susceptible to carbon absorption and under a ‘business as usual’ climate change scenario the impacts to marine ecosystems and food chains could be dire...

For the second year running, vital ecosystems are in flames. Several major fires in the Amazon have been spotted ahead of the rainforest’s typical fire season, and it seems likely that 2020 will see worse blazes than the ones which triggered international outcry last year.

Alarming heat scorched Siberia on Saturday as the small town of Verkhoyansk (67.5°N latitude) reached 100.4 degrees Fahrenheit, 32 degrees above the normal high temperature. If verified, this is likely the hottest temperature ever recorded in Siberia and also the hottest temperature ever recorded north of the Arctic Circle, which begins at 66.5°N.

The loss of summer sea ice in the Arctic is now very likely before 2050, new research shows, even if the carbon emissions driving the climate crisis are cut rapidly. The result has alarmed scientists but they said slashing greenhouse gases remained vital as this would determine whether Arctic summer ice vanished permanently or could recover over time. If emissions remain very high, there is a risk the Arctic could be ice-free even in the dark, cold winter months, a possibility described as “catastrophic”.

An “unprecedented” hole in the ozone layer which developed to become the largest ever seen over the Arctic has closed just weeks after opening, scientists observing the phenomenon have said. The gap in the vital layer, which protects the Earth from harmful radiation from the sun, set a new record for ozone depletion in the northern hemisphere when it formed earlier this month.

Antarctica and Greenland lost thousands of gigatons of ice in the last 16 years, according to results

Moss balls seem to roll around glaciers in a coordinated way, and researchers can't explain why the whole group moves at about the same speed and in the same direction.

After a 35 year hiatus, the U.S. Coast Guard is set to build a new heavy endurance icebreaker. The head of the sea service's acquisition office believes production on a new ship could start in five years—and will cost at least a billion dollars. According to USNI News, acquisition chief Rear Admiral Mike Haycock said the Coast Guard has finalized plans to buy a ship to replace the Polar Star, the service's only heavy icebreaker.

The warming Arctic has set another record. The average air temperature over Arctic land reached 1.3 degrees Celsius above average for the year ending in September. That's the highest since observations began in 1900. The new mark was noted in the annual Arctic Report Card, released Tuesday by the National Oceanic and Atmospheric Administration. The Arctic centres on the North Pole and reaches into North America and Eurasia.

BBC’s Frozen Planet

For millennia, the frozen lands of the far Northern Hemisphere have been a huge reservoir of carbon. The permafrost soils that characterize the Arctic and sub-Arctic tundra cover roughly 8 percent of the global land surface but hold half of Earth’s underground organic carbon and twice as much carbon as is currently in the atmosphere. Arctic tundra stores carbon during the summer and releases some of it during the winter.

In the Arctic, roads are magical. They appear in the fall and melt in the spring. Others, buckled by permafrost, undulate in the snow. Many are invisible to the naked eye — caribou migration routes that exist only by instinct. During the sunless, frigid winter, the Arctic Ocean becomes one vast road for polar bears and snowmobiles. Amid these roads, a new one is being built, an 85-mile sliver topped with gravel in Canada’s Northwest Territories.

The pounding noise shatters the ancient, eerie silence of the Davis Strait, a frigid finger of ocean separating Canada and Greenland. Thwick-thwack, thwick-thwack, thwick-thwack. It comes from above but the marine fog is thick, the source invisible. The sound gets closer, louder. THWICK-THWACK, THWICK-THWACK, THWICK-THWACK. The pilot wears an old red neoprene survival suit. But it's hot in the helicopter, and the bulky outfit's mittens...
