...
The new data shows that on 19 September, the area covered by ice fell to 5.35 million sq km (2.01 million sq miles), the lowest recorded since 1978, when satellite records became available; it is now 20% less than the 1978-2000 average.
The current rate of shrinkage they calculate at 8% per decade; at this rate there may be no ice at all during the summer of 2060.
An NSIDC analysis of historical records also suggests that ice cover is less this year than during the low periods of the 1930s and 40s.
Mark Serreze believes that the findings are evidence of climate change induced by human activities.
