Nancy's Almanac, Dec. 18, 2013: A cooler Earth is foreign to many

Today's young people have only known a planet that is warmer than the one their parents grew up in.

According to a report released Tuesday, November 2013 continued the 28-year-old trend of monthly temperatures being above the 20th century average.

November, with an average temperature of 56.6 degrees, became the 345th consecutive month with a temperature above the 20th century average, according to the National Oceanic and Atmospheric Administration.

Within that global average, places have been warmer and cooler than the previous century's average.

Last month, one of the largest land areas to see temperatures cooler than average was North America. The eastern half of the United States, Nebraska, Iowa and much of Canada and Mexico averaged cooler temperatures than what was seen in the 20th century.

In November, the most extreme warmth settled over Eurasia, and lesser degrees of warmth occurred in Africa, South America and elsewhere. The global temperature is rising because more of the sun's heat is being trapped inside the Earth's atmosphere than was the case generations ago.

The last time any month's average temperature fell below the global average was in February 1985. Record-keeping began in 1880.
