Arctic sea ice at record low October levels: Danish researchers - Al Jazeera English

For the month of October, measurements show an 8.2 percent downward trend in ice over the last 10 years.

According to preliminary satellite data used by the institute, sea ice surface area was at 6.5 million square kilometres (2.5 million square miles) on October 27.

It usually reaches a low point of about five million square kilometres (1.9 million square miles), but then reforms to cover about 15 million square kilometres (5.7 million square miles) in winter.

For the month of October, measurements show an 8.2 percent downward trend in ice over the last 10 years.

Germany’s Potsdam Institute for Climate Impact Research (PIK) said on Tuesday under current levels of atmospheric CO2 – about 400 parts per million – the melting of Arctic sea ice would raise global temperatures by 0.2C (32.3F).
