2015, 2016 and 2017 proclaimed the hottest in the history


The world meteorological organization announced that 2016 remains the hottest for all history of meteorological observations, 2017, however, almost caught up with him, being in the top three. At the same time to set a new record last year was prevented by a natural phenomenon, and close to it he is supposed to be proved by the people.

The temperature in 2017, as previously and in 2015 was about 1.1 degrees Celsius higher than in pre-industrial times. 2016 was hotter than another 0.1 degrees, and the difference between 2015 and 2017 do not exceed the statistical error, so the second place was shared.

The fact that 2017, in contrast to the two previous years, was not a record, generally correspond to expectations. This is due to a phenomenon called El niño, which is a cyclical warming of the surface waters of the Pacific ocean. Now these waters are cooled (this process is called La niña), so that several needs to fall and the air temperature in the world. However, the amendment is so warm and 2017 even more evidence that the planet’s climate becoming hotter, and natural variations in temperature is almost not compensate. Among all years, not “under the sign of” El niño, 2017 leads in average annual temperature by a large margin.

Anyway, experts note that in the case of global warming, it is important to pay attention primarily on long-term trends, and in this respect the picture looks pretty clear — 17 of the 18 hottest years on record belong to the XXI century and the hottest year of the previous century was 1998.

The researchers also draw attention to the fact that global warming leads to an increase in the number of droughts, floods, hurricanes and other natural disasters in many countries.

Earlier the Director of hydrometeorological Roman Vilfand said that in Russia the average temperature in 2017 was the highest over the entire period of meteorological observations.
