The World Meteorological Organisation, NASA, and the National Oceanic and Atmospheric Administration (NOAA) released data for 2019 and it showed that it was the 2nd hottest year in recorded history; with the 2010s being the hottest decade in history.
2016 took the cake (El Niño, anyone?). Something to point out is that according to Gavin Schmidt, director of NASA's Goddard Institute for Space Studies (GISS), every decade was gradually hotter than the one before it starting with 1960. No surprise here, but the last 5 years happen to be the 5 hottest years of all time.
Do you see a trend here? Where will 2020 end up?
