Across the Northern Hemisphere, several regions saw some of the hottest temperatures on record this week, according to information compiled by the Washington Post. Apart from the U.S. and Canada, these temperatures were not the result of one single heat wave, but rather several different weather systems.

Our thought bubble, from Axios Science Editor Andrew Freedman: "July is typically Earth’s hottest month, so heat records falling now is not unexpected. But 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, according to scientific studies."
