Monitored ice in the Arctic Ocean shows more than last year but climate scientists don't find this comforting.
The volume of sea ice floating in the Arctic Ocean increased by about 50 per cent in October compared to last year, which was one of the lowest on record.
Europe's CryoSat satellite, which is designed to monitor sea-ice thickness, measured about 9000cu km of sea ice compared to the 6000cu km seen in October last year.
Scientists said that the rebound probably marked a temporary respite for the polar region, which has seen dramatic and long-term changes in recent decades because of regional warming that has melted Arctic ice on both land and sea.
The extent of the surface area covered by sea ice - measured by a different satellite - also saw an increase on the previous year, however it was still the sixth lowest since satellite records began in 1979. The seven lowest recorded sea-ice extents have all occurred in the past seven years.
