The July 2022 heatwave is happening when average world temperatures have risen by just over 1C from their pre-industrial levels.

We are living in the hottest period in 125,000 years, according to the UN's climate science body, the Intergovernmental Panel on Climate Change (IPCC).

We know what is behind this - greenhouse gas emissions caused by our burning of fossil fuels like coal and gas. Concentrations of carbon dioxide (CO2) in the atmosphere are at the highest level for two million years and rising, according to the IPCC.

If all the promises governments made at the UN COP26 climate conference in Glasgow last year are actually implemented then we're looking at temperatures rising by 2.4C by the end of the century.

But the bad news is that emissions of CO2 continue to increase. Without big cuts by 2030 we could see temperatures go even higher. Perhaps as much as 4C by the end of the century, scientists predict.
