Summer 2021 is likely to be another of the hottest on record, with global temperatures forecast to be more than 1.1C above the pre-industrial average, according to estimates from the Weather Met Office.

The forecast for 2021 is based on observations over recent years that have seen a series of years more than 1C above pre-industrial levels and bearing what meteorologists said was the “clear fingerprint” of human-induced global heating.
Next year is also unlikely to see a strong natural warming event. The hottest year on record currently is 2016, when there was an El Niño effect, and the years since have all been close to the record.
If the forecast is correct, the world will come even closer to the brink of climate breakdown next year. Scientists have warned that warming of more than 1.5C above pre-industrial levels would have damaging effects on the world’s climate.
