New study shows Antarctic sea ice is the same as it was 100 years ago

The following is from an article in the London Telegraph by Science Editor Sarah Knapton.

The study was based on the ice observations recorded in the logbooks from 11 voyages between 1897 and 1917, including three expeditions led by Captain Scott, two by Shackleton, as well as sea-ice records from Belgian, German and French missions.

Antarctic sea ice had barely changed from where it was 100 years ago, scientists have discovered, after poring over the logbooks of great polar explorers such as Robert Falcon Scott and Ernest Shackleton.

Experts were concerned that ice at the South Pole had declined significantly since the 1950s, which they feared was driven by man-made climate change.

But new analysis suggests that conditions are now virtually identical to when the Terra Nova and Endurance sailed to the continent in the early 1900s, indicating that declines are part of a natural cycle and not the result of global warming.

“We know that sea ice in the Antarctic has increased slightly over the past 30 years, since satellite observations began. Scientists have been grappling to understand this trend in the context of global warming, but these new findings suggest it may not be anything new.
