National Oceanic and Atmospheric Administrations says July was Earth’s hottest month on record with an average temperature of 61.86 degrees Fahrenheit, beating the previous global mark set in 1998 and 2010 by about one-seventh of a degree. That’s a large margin for weather records that go back to 1880.
Nine of the 10 hottest months on record have happened since 2005 and it is quite likely that 2015 will end up the hottest year on record, beating last year.
