The World Meteorological Organisation (WMO) on Wednesday in Geneva said that year 2015 would likely become the hottest year since the pre-industrial era.
WMO in a report said that due to man-made global warming and the strong El Nino weather phenomenon, the average global temperature this year was set to rise one degree above the levels seen between 1880 and 1899.
Ocean surfaces have also reached record temperatures, and greenhouse gas concentrations in the atmosphere have crossed the level of 400 parts per million since January 2015.
“This is all bad news for the planet,” WMO Secretary, Michel Jarraud, said as he presented the preliminary annual assessment, ahead of the UN climate talks starting November 30 in Paris
