The current record for the most well liked year is probably going to be broken again within subsequent five years, the Met Office says.
As it stands, the most well liked year on record was in 2016, when 1.16C of warming was recorded.
Analysis shows the five-year period from 2020 to 2024 is predicted to be the most well liked five years on record globally, as temperatures over the amount are predicted to be between 1.15C and 1.46C above pre-industrial levels.
Global temperatures for every individual year are likely to exceed pre-industrial levels by between 1.06C and 1.62C.
The research reflects rising global temperatures, because the previous five years were the warmest such period on record, showing a mean warming of 1.09C.
Scientists have warned of the risks of allowing heating of quite 1.5C, and countries have committed under the Paris climate deal to stop reaching that threshold. The Met Office forecast has estimated there’s a but one in 10 chance any single year within the next five years will reach 1.5C of warming.
The head of long-range prediction at the Met Office, Adam Shaife, said: “Barring an outsized eruption , these predictions show that we are rapidly approaching the purpose where we’ll see temporary excursions of worldwide temperature above the 1.5C threshold.”
But Professor Stephen Belcher, Met Office chief scientist, said reaching 1.5C of warming in a private year wouldn’t breach the Paris agreement because the focus is on long-term temperature rises.
But he warned: “However, with our forecast showing an extra warming trend, the window of opportunity continues to narrow.”
Dr Doug Smith, a Met Office fellow and expert on decadal prediction, said the forecast suggests “continued warming, according to sustained high levels of greenhouse gases”.
According to the forecast, temperatures within the North Atlantic are expected to rise, which could exacerbate warming over Europe.
Last year, the united kingdom recorded its hottest ever temperature, reaching 38.7C (101.66F) in Cambridge Botanic Garden on 25 July.
