In September 2012, Arctic sea ice reached its lowest extent since satellite records began in 1979. While Antarctic sea ice is growing by on average 165,000 square kilometres per decade, this is dwarfed by the loss of an average of 480,000 square kilometres per decade from the Arctic. The Times and Saturdays Daily Mail articles both pick up on this comparison, the latter featuring a quote by polar scientist Walt Meier explaining why Antarctic ice growth is less significant a measure than declining Arctic sea ice coverage when assessing climate change. He says: source... carbonbrief.org/blog/2014/07/factcheck-what’s-the-significance-of-a-record-high-in-antarctic-sea-ice/#.U71cB4GyCi0.facebook When you add in the loss of ice mass from the Greenland and Antarctic ice sheets, the earth is already losing ice overall - and that will continue with further warming. climate.nasa.gov/keyIndicators/#landIce
