A record-breaking heat dome scorched the United States in late June, setting or tying high-temperature records in more than 280 locations and placing more than 130 million people under extreme heat advisories and warnings. Cities across the East Coast and Midwest shattered all-time records, while dozens of others surpassed daily highs that had stood for more than a century. Simultaneously, the United Kingdom experienced its own heatwave, with scientists finding that global warming had made such an event up to 100 times more likely to occur.This United States' heat dome constituted a clear climate story, though national TV news largely failed to treat it as one. Climate change was rarely mentioned, despite the availability of robust attribution science showing that heat domes are becoming more frequent and intense as a result of Arctic warming and global emissions. Coverage also largely ignored the heat’s disproportionate toll on low-income families, outdoor workers, and medically vulnerable populations. And it offered no meaningful scrutiny of President Donald Trump’s ongoing rollbacks of climate and public health protections — specifically cutting funding and laying off staff for federally-funded hazardous heat programs, even as his administration's actions increase the public’s exposure to deadly heat.
