Research Ship Trapped in Antarctic Ice Because Of Weather, Not Climate Change

Shokalskiy OPERATION EVIDENCE EXAGGERATE POLE EXTENT ALMOST FIND SEA MONTH 4 ARCTIC BELIEVE VARIABILITY

   The Russian ship Akademik ___ is stuck in the ___, in an area where ___ has been an increase ___ sea ice extent since ___ late 1970s, making ship ___ difficult. Is this situation ___ that global warming is ___?

   The impact of climate ___ on ice at both ___ is complex. Actually, the ___ polar regions have experienced ___ different trends in ice ___. Arctic sea ice has ___ declining in extent in ___ month of the year, ___ the maximum loss of ___ 14% per decade being ___ in September. In contrast, ___ ice extent around the ___ has increased in every ___ of the year with ___ largest increase being almost ___% per decade in March.

   ___ reasons for the trends ___ sea ice are still ___ debated. However, for the ___ it is estimated that ___ emission of greenhouse gases ___ contributed 50–60% of ___ decline of Arctic sea ___. The remaining contribution is ___ to come from natural ___. But in the Antarctic the reason for the increase in ice is less clear. The pattern of sea ice change around the Antarctic is dominated by a decrease to the west of the Antarctic Peninsula and an increase across the Ross Sea, which can be attributed to more storm activity between these two areas and to the strength and direction of the winds. This pattern of change is consistent with the increasing temperatures observed over the west Antarctica, where temperatures have risen as much as anywhere in the southern hemisphere.
