UK Met Office: 2020 set to extend series of Earth’s warmest years
A British Met Office forecast last month found the global average temperature for the coming year suggests 2020 will again extend the current series of the Earth’s modern-era hottest years.
This began in 2015 – the first year when the global temperature was more than 1.0°C above the pre-industrial period.

of the strongest factor causing temperatures
to rise: greenhouse gas emissions’
Its central estimate for 2020 is for a global temperature 1.11°C above the average for the period 1850–1900; 2016 was 1.16°C above the same baseline.
“Natural events such as El Niño-induced warming in the Pacific influence the climate system, but in the absence of El Niño, this forecast gives a clear picture of the strongest factor causing temperatures to rise: greenhouse gas emissions,” said Professor Adam Scaife, who is head of long-range prediction at the Met Office.
Met Office climate expert Dr Nick Dunstone also added: “Although the Earth has warmed by about 1.0°C on average since pre-industrial times, this isn’t spread evenly [and much of it] is occurring in the Arctic and over land masses.”
A year ago its central forecast of 1.10°C for 2019 “agreed closely with the latest observations of global temperature” last year, the Met Office noted.
