Most of the UK media stories about the record-breaking heatwave that struck in June failed to mention the climate crisis, analysis has found.

Nearly 2,500 articles about the extreme heat – when temperatures topped 37C, a record for the time of year – appeared in the UK’s nine main national daily media publications. But nearly three-quarters of them – about 72% – left out any mention of global heating or the climate, according to the analysis by the Energy and Climate Intelligence Unit (ECIU).

Even fewer pieces drew a link between the heatwave and government policies designed to tackle the climate crisis – less than one in 20 heatwave stories mentioned “net zero”.
