Global temperatures were nearly 1C above pre-industrial levels in the first 10 months of 2018, which comes in behind 2016, 2015 and 2017 in the ranking of the hottest years ever recorded, figures from five global data sets show.
The past four years have the been the hottest on record, going back to 1850, the report says, with the 20 hottest years on the list all occurring in the past 22 years.
If these trends continue temperatures could rise by as much as 3.5C (6.3F) by 2100, researchers warn.
Other signs of climate change including sea level rises, the oceans warming and becoming more acidic as they absorb carbon emissions, sea ice and glacier melting, and more extreme weather, have all been seen this year.
Global temperatures on track for 3-5 degree rise by 2100: U.N.
According to the WMO's Secretary-General, Petteri Taalas, we are "not on track" to hit climate targets and "rein in temperature increases".
With levels of greenhouse gases in the atmosphere, the main driver of climate change, at a record high, "we may see temperature increase of 3-5C by the end of the century", Taalas said.
"It is worth repeating once again that we are the first generation to fully understand climate change and the last generation to be able to do something about it", said Taalas.
The warning comes at a time when the Intergovernmental Panel on Climate Change Special report said in October this year that there is no safe level of global warming and sea levels would continue to rise for centuries even if we cap warming at 1.5°C above pre-industrial levels, prescribed in the lower limit of the Paris Agreement. For the past five years, the average rise was 1.04C.
