Last month ranked as the world's hottest April on record, tying with April 2010, U.S. weather officials announced Tuesday (May 20).
The average global temperature for April 2014 was 1.39 degrees Fahrenheit (0.77 degrees Celsius) warmer than the 20th century average for the month, which was 56.7 degrees F (13.7 degrees C), according to the latest monthly report from the National Oceanic and Atmospheric Administration (NOAA).
April 2014 and April 2010 also tied for seventh place in having the greatest departure from their monthly average (among all months) since such record keeping began in 1880, NOAA officials said.

Despite an average of hot temperatures around the planet, some regions, including the continental United States, remained tepid in April. No U.S. state recorded average temperatures that ranked in their top 10 warmest or coolest last month. Overall, the continental United States experienced its 46th warmest April since record keeping began, NOAA officials said.
Global temperatures have risen an average of 0.11 degrees F (0.06 degrees C) each decade since 1880, and they've climbed even more sharply since the 1970s — at a rate of 0.28 degrees F (0.16 degrees C) per decade, according to NOAA.
Last year was one of the hottest years on record for the planet; 2013 tied 2003 as the world's fourth warmest year since record keeping began. The 15 hottest years on record include all 13 thus far in the 21st century (2000-2013).
The monthly report is detailed on NOAA's website.
