A city in Oman set a heat record last week, but it's not the only place registering record-setting mercury. The Washington Post lists the places worldwide that have been experiencing never-before-recorded heat over the past week, caused by heat pressure or heat domes across the Northern Hemisphere. In North America, record temps have been notched in Denver (it tied its all-time high of 105 degrees), Burlington, Vt. (marking its highest "low" temperature of 80 degrees), and Montreal, which saw its highest temperature ever with a 97.9-degree reading. Eurasia and Europe also haven't been able to escape the sweltering; in the UK and Ireland, it's been so hot that roads and roofs are melting, per the Weather Channel.
While it's not surprising that July will smash some weather records, so many places experiencing them at once suggests something bigger. "So many rare milestones being set or tied worldwide does point to the influence of a warming world, given that the link between heat waves and climate change is robust," says Andrew Freedman, science editor for Axios. AccuWeather notes the tragic consequences of this weather pattern, reporting that at least 17 people have died in Montreal over the past week due to the heat, while in the US there have been at least three reported deaths. "My thoughts are with the loved ones of those who have died in Quebec during this heat wave," Canadian PM Justin Trudeau tweeted on Wednesday. A blast of cooler air out of Canada is expected to bring some relief to the Northeast and mid-Atlantic states by Friday and Saturday. (More heat wave stories.)
