My colleague Damian Carrington has written about a new assessment of the role of climate change in extreme weather events, which found that it is supercharging heatwaves, floods, storms, droughts and wildfires.
At least 24 previously impossible heatwaves have struck communities across the planet, a new assessment has shown, providing stark evidence of how severely human-caused global heating is supercharging extreme weather.
The impossible heatwaves have taken lives across North America, Europe and Asia, with scientific analyses showing that they would have had virtually zero chance of happening without the extra heat trapped by fossil fuel emissions.
