For seven consecutive months the global average temperature has been at least 1C above the 1951-80 mean for that month.

Last month was the hottest April on record globally – and the seventh month in a row to have broken global temperature records. Nasa data shows that the global temperature of land and sea was 1.11C warmer in April than the average temperature for April during the period 1951-1980. more

The BBC have a graphic which shows how the average global temperature has risen

“The combined average temperature over global land and ocean surfaces for April 2016 was 1.10°C (1.98°F) above the 20th century average of 13.7°C (56.7°F)—the highest temperature departure for April since global records began in 1880. This value surpassed the previous record set in 2010 by 0.28°C (0.50°F). This was also the fourth highest monthly temperature departure among all 1,636 months on record, behind March 2016 (1.23°C/2.21°F), February 2016 (1.19°C/2.14°F), and December 2015 (1.12°C/2.02°F). Overall, 13 out of the 15 highest monthly temperature departures in the record have all occurred since February 2015, with February 1998 and January 2007 among the 15 highest monthly temperature departures. April 2016 also marks the fifth consecutive month (since December 2015) that the global monthly temperature departure from average has surpassed 1.0°C (1.8°F) and it is the 12th consecutive month a monthly global temperature record has been broken, the longest such streak in NOAA’s 137 years of record keeping.” more
