The global average temperature for January, 2013 was 0.54°C, or 0.97°F, above the 20th century average, according to an update just issued by the National Climatic Data Center.

That makes January the ninth warmest since record-keeping began in 1880.

Some notable findings:

  • The Southern Hemisphere experienced record warmth over land for the second month in a row
  • In Australia, the nationally-averaged monthly maximum temperature in January was the highest ever recorded.
  • The southern portion of Greenland was considerably warmer than normal.

The warmth in Greenland explains the unusual melting of snow along the southeastern coastal area of Greenland. I wrote about that on Monday in this piece. The melting continues, as today’s Greenland Ice Sheet Today graphic from the National Snow and Ice Data Center shows.
