WMO = World Meteorological Organization announced that last year's average global temperature was comparable to 2016, the highest in the history of observations, despite the "La Niña phenomenon" that tends to lower temperatures.
The WMO announced on the 14th that the average global temperature over the last year was 14.9 degrees Celsius, about 1.2 degrees Celsius higher than the pre-industrial level.
Last year, the "La Niña phenomenon," which tends to lower the temperature of the world, occurred, but it is said that the heat was comparable to 2016, which was the hottest year in the history of observation.
The 10 years from 2011 are also said to be the hottest 10 years in the history of observation.
The United Nations calls for keeping the global average temperature rise within 1.5 degrees Celsius to prevent serious damage from global warming.
UN Secretary-General António Guterres said, "The world is heading for a catastrophic temperature rise of 3 to 5 degrees Celsius during this century. Reconciliation with nature must be a top priority for everyone and everywhere. It must not be done, "he said, calling for stronger measures.
