First half of 2013 ranks 7th warmest on record

Halfway through the year, the Earth as a whole ranks in the top 10 warmest years on record. 

Looking at the NASA and NOAA temperature data analysis, Climate Central lists the highlights of the heat below.

  • Through mid-year, the globe is running 1.06°F above the 20th century average.
  • That temperature is averaged from both land and ocean temperatures.
  • January-June 2013 is tied with 2003 as the 7th warmest on record - for the first half of the year.
  • The land temperature alone is the 6th warmest: running 1.80°F above average.
  • The ocean temperature alone is 7th warmest: running 0.79°F above average.
  • If you take a close look at the graphic above, you will see that there are regional variations in the overall averaged temperature.
  • June marks the 340th consecutive month (a total of more than 28 years), with a global temperature above the 20th century average. The last below-average temperature for any month was February 1985. 
This not to say there haven't been record lows or cool temperatures at times. The data is analysis of the global average which includes ALL of the numbers.  Overall, the temperatures have been warm compared to the 100 years that make up the 20th century.
