This edition of Carbon Brief's DeBriefed newsletter covers three major climate stories from early July 2026. The US is facing a severe heatwave over the Independence Day weekend, with dangerous temperatures expected across multiple states. Meanwhile, global ocean temperatures have hit a new record, continuing a worrying trend that scientists link to climate change. In Vietnam, electric vehicle sales are surging as the country pushes for cleaner transport, a shift that could cut emissions significantly if the grid keeps up. The newsletter also includes a roundup of recent climate research, policy updates, and key figures from the past week. It is a useful snapshot for anyone tracking extreme weather trends, ocean warming, or the pace of EV adoption in emerging economies.
