From the normally mild summer climes 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.

The Canadian Broadcasting Corporation reports the heat is to blame for at least 33 deaths in southern Quebec, mostly in and near Montreal, which endured record high temperatures.

In Northern Siberia, along the coast of the Arctic Ocean – where weather observations are scarce – model analyses showed temperatures soaring 40 degrees Fahrenheit (22 Celsius) above normal on July 5, to over 90 degrees Fahrenheit (32 Celsius).

“It is absolutely incredible and really one of the most intense heat events I’ve ever seen for so far north,” wrote meteorologist Nick Humphrey, who offers more detail on this extraordinary high-latitude hot spell on his blog.

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 southeast Canada since late last week. It’s not only been hot but also exceptionally humid. Here are some of the notable all-time records set:

Denver tied its all-time high-temperature record of 105 degrees Fahrenheit (40.5 Celsius) on June 28.

Mount Washington, N.H., tied its all-time warmest low temperature of 60 degrees Fahrenheit (15.5 Celsius) on July 2.

Burlington, Vt., set its all-time warmest low temperature ever recorded of 80 degrees Fahrenheit (26.6 Celsius) on July 2.

Montreal recorded its highest temperature in recorded history, dating back 147 years, of 97.9 degrees Fahrenheit (36.6 Celsius) on July 2. The city also posted its most extreme midnight combination of heat and humidity.

Ottawa posted its most extreme combination of heat and humidity on July 1.

Europe

Excessive heat torched the British Isles late last week. The stifling heat caused roads and roofs to buckle, the Weather Channel reported, and resulted in multiple all-time record highs:

Scotland provisionally set its hottest temperature on record. The U.K. Met Office reported Motherwell, about 12 miles southeast of Glasgow, hit 91.8 degrees Fahrenheit (33.2 Celsius) on June 28, passing the previous record of (32.9 Celsius) set in August 2003 at Greycrook.

Additionally, Glasgow had its hottest day on record, hitting 89.4 degrees Fahrenheit (31.9 Celsius).

In Ireland, on June 28, Shannon hit 89.6 degrees Fahrenheit (32 Celsius), its record.

In Northern Ireland,

Belfast hit 85.1 degrees Fahrenheit (29.5 Celsius) on June 28, its record.

Castlederg hit 86.2 degrees Fahrenheit (30.1 Celsius) on June 29, its record

Eurasia

A large dome of high pressure, or heat dome, has persistently sat on top of Eurasia over the past week, resulting in some extraordinarily hot weather:

Tbilisi, Georgia: On July 4, the capital city soared to 104.9 degrees Fahrenheit (40.5 Celsius), its all-time record.

Yerevan, Armenia: On July 2, the capital city soared to 107.6 degrees Fahrenheit (42 Celsius), a record high for July and tying its record for any month.

Several locations in southern Russia topped or matched their warmest June temperatures on record on the 28th.

Middle East

As we reported, Quriyat, Oman, posted the world’s hottest low temperature ever recorded on June 28: 109 degrees Fahrenheit (42.6 Celsius).

These various records add to a growing list of heat milestones set over the past 15 months that are part and parcel of a planet that is trending hotter as greenhouse gas concentrations increase because of human activity:

In April, Pakistan posted the hottest temperature ever observed on Earth during the month of 122.4 degrees Fahrenheit (50.2 Celsius).
Dallas had never hit 90 degrees Fahrenheit in November before, but it did so three times in four days in 2017.
In late October 2017, temperatures soared to 108 degrees Fahrenheit in Southern California, the hottest weather on record so late in the season in the entire United States.

On Sept. 1, 2017, San Francisco hit 106 degrees Fahrenheit, smashing its all-time hottest temperature.

In late July 2017, Shanghai registered its highest temperature in recorded history, 105.6 degrees Fahrenheit (40.9 Celsius).

In mid-July, Spain posted its highest temperature recorded when Cordoba Airport (in the south) hit 116.4 degrees Fahrenheit (46.9 Celsius).

In July 2017, Death Valley, Calif., endured the hottest month recorded on Earth.

In late June 2017, Ahvaz, Iran, soared to 128.7 degrees Fahrenheit Fahrenheit (53.7 Celsius) — that country’s all-time hottest temperature.

In late May 2017, the western town of Turbat in Pakistan hit 128.3 degrees Fahrenheit (53.5 Celsius), tying the all-time highest temperature in that country and the world-record temperature for May, according to Masters.
