The UK's record-breaking heatwave in June 2026 was accompanied by an alarming silence on the climate crisis in mainstream media. Research conducted by the Energy and Climate Intelligence Unit (ECIU) reveals that a staggering 72% of nearly 2,500 articles across top national publications failed to mention global heating or climate change.
Temperatures soared above 37C in June, breaking previous records for that time of year, with May's hot spell reaching 35C. The escalating frequency and intensity of such events are starkly illustrated by the fact that fewer than one in twenty heatwave stories drew a link to government policies aimed at tackling the climate crisis, such as 'net zero' initiatives.
The human cost is devastating: research from Imperial College London estimates around 2,700 people died from overheating in May and June, with approximately 1,100 of these fatalities directly attributed to the additional heat caused by the climate crisis. Scientists agree that human actions – particularly burning fossil fuels and intensive agriculture – have supercharged this hot weather, making extreme conditions impossible without human interference in the climate system.
The ECIU's analysis focused on articles published between Monday 22 June and Sunday 28 June 2026, tracking references to 'extreme heat' or 'heatwave' alongside terms like 'climate change' or 'global warming'. While some publications performed better than others – the Financial Times and The Guardian making more frequent links – the overall picture is one of significant omission. The Independent, despite publishing 783 stories on the heatwave, linked only about 39% to climate, whereas The Sun ranked lowest with just 6% of its 69 heatwave stories mentioning a climate angle.
Gareth Redmond-King, head of international at the ECIU thinktank, stressed that recent periods of extreme heat are inextricably linked to climate change. He likened heatwaves to symptoms of a greater illness – climate change – and net zero policies as essential medicine. The findings highlight a critical gap in public discourse and awareness, hindering understanding of increasingly frequent and deadly extreme weather events in the UK.
