Meanwhile, a new paper from the Climate Crisis Advisory Group, founded by the former UK chief scientist Prof Sir David King, asks whether rapid heating in the Arctic region is driving changes in the jet stream in a way that influenced the recent weather extremes.

The jet stream is a core of strong winds travelling west to east about five to seven miles above the Earth.

The new paper said: "We are simultaneously witnessing weather disaster in Germany, the highest temperatures for June in Finland and the US, the catastrophic heatwave in British Columbia, and extreme heat in Siberia.

"These are all outlier events that exceed what one would expect if it were 'only' a 1.2C warming impact (that's the amount the Earth has already warmed since pre-industrial times).

"Greenhouse gas levels are already too high for a manageable future for humanity."

The paper, which has not been peer-reviewed, urges governments to start removing greenhouse gases at scale from the atmosphere.
