The global average surface temperature in 2015 is likely to be the warmest on record. According to the World Meteorological Organization (WMO), this is due to a combination of a strong El Niño and a known increase in global temperatures. In addition, 2011-2015 has been the warmest five-year period on record.
“Levels of greenhouse gases in the atmosphere reached new highs” said WMO Secretary-General Michel Jarraud. He believes it probable the earth’s average temperatures will reach 1°C (1.8° F) above pre-industrial era.
The already powerful El Niño influences weather patterns in many parts of the world and fueled an exceptionally warm October. The full impact of El Niño on the global temperature is likely to continue after its peaks. This could mean 2016 will likely be even warmer.
