China News Service, June 29. According to a report by Singapore’s Lianhe Zaobao, a rare heat wave hit western Canada and the Northwestern United States, setting high temperature records. High temperature warnings were issued from Oregon in the United States and even as far as the Arctic in Canada.

On June 27, 2021, local time, many cities in the Northwestern United States experienced the highest record high temperature in history.

The picture shows a large number of tourists cooling off on the water.

　　The temperature in British Columbia, Canada, soared to 46.6 degrees Celsius on the 27th, the highest temperature ever in Canada.

In addition to this province, Alberta, Yukon Territory, Northwest Territories and parts of Saskatchewan Province, known as Canada’s "food basket", have issued high temperature warnings.

　　Environment Canada said: "A long-lasting, dangerous, and historic heat wave will last the entire week." It is expected that there will be high temperatures of nearly 40 degrees Celsius in many places, or temperatures that are 10 to 15 degrees Celsius higher than normal.

　　Mobile air conditioners and fans in stores in the country were sold out. Several cities opened emergency summer shelters and dispatched people to the streets to distribute drinking water and hats.

Several new crown vaccination clinics are temporarily closed, and the school announced that it will be closed on the 28th.

Dangerous high temperatures increase the risk of wildfires and may also increase air pollution.

　　In the United States, Portland, the largest city in Oregon, had a temperature of 44.5 degrees Celsius on the 27th, the highest temperature since 1940 on record.

Seattle, the largest city in Washington state, experienced a high temperature of 40 degrees Celsius, the highest in 12 years.

　　Monoma County, where Portland is located, has opened 11 emergency summer centers, mostly in public libraries, so that residents without air conditioning in their homes can temporarily escape the hot weather.

Local health official Waynes said: "The heat is enough to threaten lives."

　　The National Weather Service issued a warning that "dangerous heat waves" will occur in parts of Washington and Oregon, which may cause record temperatures, which are more than 17 degrees Celsius higher than normal.

　　The agency said in a statement: "The historic heat wave in the Northwest region will continue for most of the next week, and may rewrite daily, monthly and even historical records of the highest temperature many times."

　　According to the report, this extreme high temperature was caused by the "heat dome" that appeared over western Canada and the northwestern United States.

"Heat dome" refers to the stagnation of hot high-pressure areas in the sky, and constantly repels cold air like a pump, absorbs hot air, and makes the temperature rise higher and higher.
