Carbon Brief roundup: 'Impossible' heat, global ocean record, and ozone hole climate link

Carbon Brief's July 7, 2026 roundup covers three major climate stories: an extreme heat event described as 'impossible' without climate change, a new global ocean temperature record, and new research linking the ozone hole to climate patterns. The article collects media coverage and scientific commentary on these events, showing how each ties back to rising greenhouse gas emissions and the broader climate system. For anyone tracking climate impacts and the urgency of decarbonization, this roundup is a useful snapshot. The ocean heat record in particular has direct implications for marine ecosystems and weather patterns. The ozone hole research adds another layer to how atmospheric changes interact with surface warming. Worth a read if you want a quick summary of the week's key climate science stories.
