The Fort Worth Press - Arctic sea ice levels second lowest on record for January: US data

The US National Snow and Ice Data Center (NSIDC) said the Arctic sea ice surface area was at a record low in December and continued near record lows in during January. It said the surface in January averaged 13.13 million square kilometers (5.07 million square miles).

"In contrast to the cold conditions dominating the contiguous United States, much of the Arctic experienced above-average January temperatures," the NSIDC said.

This was particularly marked north of Greenland and over central Alaska, the report said, with temperatures as much as eight degrees Celsius (14 degrees Fahrenheit) above average for the month.

Greenland is located between the United States and Europe in a region of increasing strategic value as the melting of Arctic sea ice opens up new shipping routes.

President Donald Trump has signalled that he wants the Arctic island -- which is believed to hold large untapped mineral and oil reserves -- to become part of the United States.

Last year annual surface air temperatures in the Arctic were the second-warmest on record, according to the US National Oceanic and Atmospheric Administration.

Rising temperatures melt sea ice which in turn contributes to accelerated warming in the region, as dark sea water absorbs more solar radiation and thus helps to heat up the atmosphere, which then further accelerates the melting of the ice.

In a 2023 study, researchers found that the Arctic Ocean's ice cap would likely disappear in summer as soon as the 2030s and a decade earlier than thought, no matter how aggressively humanity draws down the carbon pollution that drives global warming.

The retreating ice also has a major impact on polar bears, which need sea ice to hunt.

A study published in the journal Science last week found that around half of the decline in Canada's Hudson Bay polar bears from 1979 to 2021 was due to climate-driven sea ice loss.
