In the entire history of observations 2016 was the hottest
For the entire period of meteorological observations, which lasted from 1880, the year 2016 was the hottest ever, breaking the previous record of 2015 by 0.1 and 0.12 degrees.
According to the scientists, NASA and the British met the main causes of this warming is emissions of CO2 in the atmosphere and the phenomenon El niño, which caused a warming of the surface waters of the Pacific ocean, and the warming in the Arctic.
However, some scientists say that even without the influence of El Nino 2015 and 2016 would still be the hottest on record, since the main influence on climate is carried out greenhouse gases and global warming.
According to the weather service, since 1880, of the 16 hottest years in the 15-th to the period 2002-2016 Such long term warming leads to global climate change.
the Volume of glaciers of the Antarctic and Arctic regions also hit record lows. Their melt changes ocean currents and weather in different parts of the world. In addition, the thawing of permafrost creates additional risks of methane emissions. Scientists note that the Arctic temperatures are rising twice as fast as the world average.
meteorologists confirmed that now the Earth's temperature by 1 degree exceeds the performance of the pre-industrial period. Signed at the 2015 Paris agreement provides for the adoption of measures to limit greenhouse gases to global temperatures do not exceed preindustrial levels by more than 1.5 degrees. However, the performance of this agreement is under threat because even during his own election program D. trump promised to abolish the Treaty of Paris, because I doubt the existence of global warming. After his accession to the position of the scientific community fears that the political support of the struggle for climate protection could disappear.
Because now signs of slowing down climatic changes are not visible, you need to spend decarbonize modern economy that will avoid the adverse effects of such changes.
Researchers believe that 2017 will be included in the list of the hottest, although not able to beat temperature records 2016.
