article imageExtreme heat sets records across the Northern Hemisphere

By Karen Graham     Jul 5, 2018 in Environment
The northern hemisphere has been hit by extreme heat over the past two weeks, with record-breaking temperatures recorded in the US, Canada, Europe and the Middle East.
The recent persistent heatwave has resulted in 11 deaths in Montreal, 33 deaths in Quebec. at least 20 in the U.S. and six in the United Kingdom.
“This has been a prolonged and intense heat event across Eastern Canada,” Global News meteorologist Ross Hull said. “This has been the hottest stretch of weather in more than a decade and record-high temperatures have been shattered, especially in Montreal where record-high temperatures dating back to 1963 were broken on July 1 and 2.”
And according to the National Weather Service forecast for July, August, and September, it will be a long summer over much of the US with temperatures at or above normal. The highest temperatures will be seen in New England and the west coast south to southern California and east to the Rocky Mountains.
There were some records set with this heat wave, including Scotland’s hottest day ever on record that saw a temperature of 33.2 degrees Celsius (91.7 degrees Fahrenheit) in Motherwell on June 28. In Rostov-on-Don, Russia, a record temperature of 37 degrees Celsius (98.6 degrees Fahrenheit) was set on Jun29. is reporting that it was so hot in Glasgow that some of the weatherproof membranes on the roof of a science center started melting and oozed down the side of the building, while across the British Isles, roads buckled and pavement melted in the intense heat.

And in the Middle East and south-west Asia - regions famous for their extreme summer heat - this heat wave has been unbearable. in Quriyat, Oman, the highest minimum temperature ever recorded on Earth during a 24-hour period was set on June 27, when the temperature never dropped below 108.7 degrees Fahrenheit (42.6 Celsius).
Interestingly, this sweltering episode for Oman is the second weather extreme to strike the nation in the past two months. In May, Category 3 Tropical Cyclone Mekunu slammed into its southwest coast and is the most intense tropical cyclone to make landfall on the Arabian Peninsula on record.
These weather events can be blamed on global warming that has caused some deviations in the Jet Stream that blows winds from the Westcto the East in the upper atmosphere. The movements of these waves of wind play a key role in weather events in the Northern Hemisphere.
"Summers keep getting hotter," said Friederike Otto of the University of Oxford, who researched last summer’s heatwave, according to Yahoo News UK. "Heatwaves are far more intense than when my parents were growing up in the 1950s. If we do nothing to reduce our greenhouse gas emissions, the kind of extreme heat we saw this past summer will be the norm when my young son is a grown man."
