April 2014 was the 350th month in a row with above-average global temperatures, according to NASA. At 58.5°F/14.7°C, compared to an average of 57.2°F/14°C between 1951 and 1980, April was the second-warmest month on record. The U.S. posted average temperatures, with a NOAA climate scientist attributing extended cold through eastern North America to warm sea surface temperatures in the northern Pacific.
