Antarctic sea ice is not shrinking – 100 years after Shackleton Expeditions

Antarctic sea ice had barely changed from where it was 100 years ago, scientists have discovered, after pouring 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.

  1. A positive sign of the Antarctic’s resilient, if only the Arctic was so lucky!

  2. More cherry picking, just what percentage of the antarctic sea ice did those early explorers observe.

    • They observed the ice edge over many voyages.

      • Circumnavigations? What about the age and thickness of the sea ice?

      • Most Antarctic Sea Ice seasonal. But think of this like tree rings … only less magical.
