Let's begin with the global temperature anomalies for November to April, which show the past cold season really was quite remarkable, running more than 1ºC (2ºF) above the 20th century average. The tremendous surge during this period is largely a result of long-term global warming combined with El Nino.
And, speaking of sea ice, the Arctic sea-ice extent is currently running well below prior seasons in the satellite record. Perhaps a record minimum will be reached in September.
Although we may see a temporary decline in global temperature anomalies from their El Nino fueled highs this past cold season, the global warming train has left the station and is accelerating. The great melt is underway.
