Arctic sea ice shrinks to third-lowest summer minimum on record
Arctic sea ice shrank to its third- lowest summer minimum on record, remaining ``well outside the range of natural variability,'' the US National Snow and Ice Data Center in Boulder, Colorado, said.
Arctic sea ice, a key indicator of climate change, melted to its lowest level on record this year before beginning its autumnal freeze, researchers at the US National Snow and Ice Data Center said on Wednesday.
