The U.K.'s weather service, the British Met Office, says the global mean temperature is expected to rise between 0.72 degrees Celsius and 0.96 degrees Celsius above temperatures from the latter half of the 20th century.
A researcher said: "2015 is on track to be the warmest year on record, and this forecast suggests 2016 is likely to be at least as warm, if not warmer."

The British Met Office doesn't expect constant, consecutive record-breaking temperatures. But notable 2015 and 2016 temperatures show how impactful natural weather fluctuation in combination with man-made factors can be. (Video via British Met Office)
