The ‘Heat Dome’ that sets American and Canadian temperatures on record Global warming

In British Columbia’s Lytton, thermometers hit 46.6 degrees Celsius on Sunday (27), higher than the record 84 years ago, officials said.

• Canada hits record temperature again, and thermometers 47.5. Showing C
• United States faces 20-year historic heat wave and worst drought, Federal Monitor finds

An event known as the heat dome or dome (high constant pressure acting like a pot lid) led to recordings of high temperatures in other parts of North America.

The United States and Canada have warned residents of the dangers surrounding such temperatures, which could last throughout the week.

Experts say climate change associated with global warming will increase the frequency of extreme weather events such as heat waves. However, it is difficult to link an isolated event to an increase in the planet’s temperature.

BBC meteorologist Nick Miller explains that this “heat dome” is not a clear-cut meteorological term, but is often associated with describing large areas of high pressure, resulting in cloudy skies and hot, sunny days.

This high pressure situation will last, the heat wave will be very intense and the temperature will increase every day.

This high pressure zone is very large, extending from California through the interior of Idaho to the Arctic regions of Canada.

Sales of air conditioners and fans exploded and cooling camps opened. Some bars and restaurants, and even a swimming pool were considered too hot to operate.

Lytton, about 250 km northeast of Vancouver (western Canada), broke the previous Canadian record of July 1937 with temperatures reaching 45 C in two cities in the province of Saskatchewan.

David Phillips, senior climate analyst at Environment Canada (a department of the country’s Ministry of Environment), told CDV: “I want to break a record, but it’s like breaking it and triggering it. Western Canada (United Arab Emirates) than Dubai “.

Parts of the country will be higher than 47 C, the expert said.

British Columbia energy suppliers claim increased demand for electricity to run air conditioners.

Environment Canada has issued this warning to other parts of the country and predicts that “a long, dangerous and historic heat wave will continue this week” with temperatures hovering between 10 ° C and 15 C higher than normal.

‘Historic’ heat in northwestern America

The Northwest United States also broke records. The country’s National Weather Service (NWS) called the heat waves “historic” and said they would last throughout the week and “likely to set numerous daily, monthly and even historical records.”

Portland and Seattle, the cities with the most popular climates for rainfall, recorded the highest temperatures in their history. According to official data, when the temperature reached 44 C the first broke its previous record and the second it reached 40 C.

The state of Oregon, where Portland is located, has relaxed anti-epidemic controls on the Govt-19 to allow the opening of air-conditioned areas such as swimming pools and shopping malls. However, a pool in Seattle had to be closed due to “dangerous and unsafe temperatures in the pool deck”.

Fruit growers are rushing to harvest crops for fear that the heat will spoil the cherries and other produce. But the harvest should be stopped at lunch as the temperature is unbearable.

PJ Darby, chairman of the Northwest Cherry Farmers’ Coordinating Committee, told the Seattle Times: “We are traveling in completely unknown waters.”

On Sunday, the U.S. Olympic qualifiers had to be halted in Eugene, Oregon due to heat. The public was asked to leave the grounds for security reasons. Some vaccination centers were closed for the same reason.

All citizens were advised to stay hydrated, avoid harsh measures, and monitor vulnerable neighbors.

Analysis of “Climate Emergency” by Roger Harab, an expert on environmental themes:

“We can’t say for sure that this brutal heat wave is exacerbating the greenhouse effect caused by greenhouse gas emissions, but scientists argue that every heat wave that occurs today is more and more intense due to man-induced climate change.

In fact, scientists have greatly improved the ability to link extreme events to climate change, such as the heat wave that hit Europe in 2019, which could be 100 times more likely to be caused by carbon dioxide emissions, researchers say.

What is even more worrying is that these temperatures were reached with global temperatures 1.1 உலக C higher than pre-industrial periods.

The Intergovernmental Panel on Climate Change assumes that in a short period of time we will have 1.5 விட C above that level. At current rates we will cross the 2 C rise and may be higher.

However, China and India continue to build coal-fired power plants. Moreover, the G7 (Canada, France, Germany, Japan, the United Kingdom and the United States), the world’s richest economies, have not set a deadline to end this type of energy production.

Arguing that they will be needed by 2050, the UK and other countries are still drilling wells to burn oil and gas.

All of these definitely point to a climate emergency. “
