Scorching temperatures are sweeping across the globe, with the UK setting an all-time heat record and more than 100 million people under excessive warning or heat advisories in the US.
In southern and western Europe, more than 1,100 people have died from the heat in the region, as wildfires continue to rage in France and Spain.
Hot records are outpacing cool records by more than 10-to-1 so far this year. Climate scientists tell CNN this concerning trend has become more notable in recent years, and is what they would expect from climate change.
