Both the North and South Poles show alarming global climate changes, indicating that both the Arctic and Antarctic are at major risk. The National Snow and Ice Data Center, or NSIDC, released information that was obtained from satellite data which showed for the very first time in recorded history, the sea ice level may just beat the nearly 8 million square miles that has been the record high level in the Antarctic.
The rise in Antarctic sea ice level might seem to contradict set modifications in universal climate, although it is not what scientists think about when they look at various causes behind it. The increase of ice is due to the strong winds and open hole in the Ozone layer over the Antarctic. This is not good for the South Pole.
By contrast, ice in the Arctic sea is melting away, according to the NSIDC. The ice cap located in the Arctic was measured at just under 2 million square miles on Sept. 15 of this year. That was in comparison to 2013’s low of just over 2 million square miles. Records stated that this was the sixth lowest ice level since satellite tracking started in the late 1970s.
Axel Schweiger, who works at the University of Washington’s Polar Science Center explained that in the short term, it appears that there has not been a lot of ice loss in the Arctic, but one must instead look at the long term trend of declining sea ice. It is not expected that each year should be a record low. That is not good for the North Pole.
In fact, both the North and South Poles are showing drastic changes. In order to have a better look at what is going on at each of the poles, sea ice is now expanding and shrinking in relation to seasonal changes in the Antarctic in extremes. However, in the Arctic the ice used to stay solid the entire year through. The ice that remained from the prior year would help stop any extreme melting of the Arctic ice, since the multi-year ice would become thicker and allow the ice to need more time to melt in the heat than any newer layers that had been created.
The North Pole and South Pole are apparently polar opposites, no pun intended. This is not what scientists want to be seeing. However it seems the connection between climate change and melting ice is more able to be seen in the Arctic than in the Antarctic. This is because in Antarctica, some areas of sea ice continue to expand as was stated above. The entire effect appears to be growth of about one percent per every 10 years but Antarctica’s ice sheet is growing smaller, with some Antarctic glaciers actually melting as well, just like the Arctic.
Scientists believe that the Antarctic’s recent record high ice levels might have come from very strong winds. The southern polar vortex has been found to be blowing nearer to the continent itself. This could be due to a possible result of the ozone hole that is located over Antarctica combined with greenhouse gases, stated several different research studies. The harsh winds cause the ice to pack harder and also move ocean currents in a mode which caused the formation of ice.
However, the most recent studies on global warming have stated that models which have been drawn up for Antarctic sea ice developments continue to be incomplete as are studies for the Arctic. Both the North and South Poles show alarming changes but these changes need to be studied in more depth.
