What is a heat dome? Thanks for asking!
The Pacific north-west is typically a mild region when it comes to weather. But in late June, Western Canada experienced record temperatures, with the province of British Columbia hit particularly hard. Temperatures are usually around 21° on the Pacific coast, but reached 49.5°C in Lytton, a village around 100 miles to the North-east of Vancouver.
Cities on the other side of the border weren’t spared either, with Portland and Seattle both seeing their respective record temperatures smashed. We’re used to talk of heatwaves, but observers have labelled the latest situation a heat dome.
What’s the science behind these extreme temperatures? How dangerous is the heat dome? To what extent are heat domes due to climate change? In under 3 minutes, we answer your questions!
