Global Warming Melts Polar Ice To Record Lows As Temperatures Rise Under Climate Change Effects

21 November 2016.

They are quite literally poles apart but both the North Pole and the South Pole have something unfortunate in common at the moment:
They are both seeing the lowest levels of sea ice since modern record-keeping began.

News about the Arctic sea ice being at its lowest level ever for this time of the year - it hits its minimum in September and starts to build up again in October as the six-monthlong polar winter sets in - came a few days ago.

Temperatures near North Pole are said to be 36 degrees higher than normal for this time of the year, and the sea ice level - which has fallen by about half since records began in 1979 - is lesser than its previous low of 2012.

On the other end of Earth, Antarctica behaves very differently from the Arctic, and many years have seen an increase in Antarctic sea ice.

In fact, after increasing for three consecutive years, Antarctic sea ice had reached its maximum recorded extent in 2014 before falling back to average levels in 2015, but as NASA pointed out, the decrease in Arctic sea ice was three times greater than the increase seen in the Antarctic at the time.
