The temperatures during each of the next five years are forecast to go 1C or above compared to the levels recorded after the Industrial Revolution as the world is about to experience the warmest decade ever recorded.

If the forecast is proved accurate, the decade between 2014 and 2023 will be the hottest period since records began in 1850.

According to a NASA report that was published almost simultaneously with the predictions, the year of 2018 was the hottest year on record.

The analysis of the World Meteorological Organisation showed that five leading international datasets confirmed that the global average temperature in 2018 was about 1C above the levels of 1850-1900. It makes it the fourth warmest year ever recorded, following 2016, 2015 and 2017 and making the last four years the hottest on record.

Countries vowed to take actions to keep the global temperatures from going 1.5C above pre-industrial levels under the Paris Climate Agreement.
