Washington: From the normally mild summers of Ireland, Scotland and Canada to the scorching Middle East, numerous locations in the Northern Hemisphere have witnessed their hottest weather ever recorded over the past week.

Large areas of heat pressure or heat domes scattered around the hemisphere led to the sweltering temperatures. No single record, in isolation, can be attributed to global warming. But collectively, these heat records are consistent with the kind of extremes we expect to see increase in a warming world.

Let's take a tour around the world of the recent hot-weather milestones.

North America

A massive and intense heat dome has consumed the eastern two-thirds of the United States and south-east Canada since late last week. It's not only been hot but also exceptionally humid. Some of the notable all-time records include:  Denver tied its all-time high-temperature record of 40.5 degrees Celsius on Thursday; Burlington, Vermont, set its all-time warmest minimum temperature ever recorded of 26.6 degrees on Monday; Montreal recorded its highest temperature in recorded history, dating back 147 years, of 36.6 degrees on Monday. The city also posted its most extreme midnight combination of heat and humidity.
