Records melt in another hot year for the climate The Age 7 Aug 2013
» Sea levels reached a record high, possibly linked to the Pacific Ocean phenomenon La Nina, which can have a cooling effect
» Arctic sea ice shrank to its smallest summer minimum since satellite records began 34 years ago, while Antarctic sea ice reached a record high
» More than 97 per cent of the ice sheet covering Greenland melted at least a bit in the summer of 2012, four times greater than the 1981-2010 average
» Average sea surface temperatures rose, but not much, making 2012 among the 11th warmest years on record
» Ocean heat was near-record high levels in the upper 800 metres of the water, and temperatures also increased in the deep ocean
Meant to be a guide for policymakers, the report did not attribute the changes in climate to any one factor, but made note of continued increases in heat-trapping greenhouse gases including carbon dioxide, methane and nitrous oxide.
