The changes shown appear to be highly regional and/or related to known geothermal sources, rather than more uniform changes as would be expected from global warming.
Antarctic sea ice extent has recently hit record highs, but that too is being [falsely] blamed upon global warming. Climate models falsely claimed Antarctic sea ice would decrease, and that Antarctic sea ice would decrease more than Arctic sea ice.
