April 2014 Tied for Earth's Warmest April on Record

Departure of temperature from average for April 2014, the warmest April for the globe since record keeping began in 1880. Much of central Siberia observed temperatures more than 9°F (5°C) above the 1981-2010 average. This region, along with parts of eastern Australia and scattered regions in every major ocean basin, were record warm. Many nations in Europe experienced a top-ten warmest April, including Spain (2nd), Germany (4th), United Kingdom (4th), Denmark (4th), Norway (7th), and Austria (10th.) Parts of southern and eastern Canada, the northern U.S., and southern Kazakhstan were cooler than average. No land areas were record cold. (Credit: National Climatic Data Center) Click to enlarge.
April 2014 tied with April 2010 as Earth's warmest April since records began in 1880, said NOAA's National Climatic Data Center (NCDC) today, making April the first month since November 2013 to set a global monthly temperature record.  NASA rated April 2014 as the 2nd warmest April on record; global land temperatures were the 3rd warmest on record, as were global ocean temperatures.  The year-to-date January - April period has been the 6th warmest on record for the globe.  Global satellite-measured temperatures in April 2013 for the lowest 8 km of the atmosphere were 11th or 7th warmest in the 36-year record, according to Remote Sensing Systems and the University of Alabama Huntsville (UAH), respectively. 

Northern Hemisphere snow cover during April was the 6th lowest in the 48-year record.
