If melting power cables in Portland, Oregon isn’t enough to explain the problem, new satellite data confirms what many sweaty Americans might have guessed: June 2021 is the hottest June on record in North America. The 4,444 new data come from the European Union’s Copernicus Project, which measures the climate through billions of observations from satellites, airplanes and weather stations around the world. According to the new plan report in June 2021, last month was also the world’s fourth hottest June on record and the second hottest June on record in Europe.
Although human-induced climate change has steadily increased the average summer temperature year over year (2020 and 2016 are the hottest years on Earth, as previously reported by Live Science), abnormal weather has also led to high temperatures in North America. This month, record heat waves in the Pacific Northwest and western Canada swept through densely populated cities like Seattle and Portland, with stagnant air for several days. The culprit is a dangerous weather phenomenon called the Omega Block, which is essentially a dome of hot air trapped in place by a large current.

On June 28, Seattle ushered in the hottest day in its history – a very hot temperature of 108 degrees Fahrenheit (42 degrees Celsius), which is roughly higher than normal high temperature this time. 34 degrees Fahrenheit (19 degrees Celsius). According to the report “Washington Post”, this year. Not to be left out by American exceptionalism, Canada set a national record for the highest temperature for three consecutive days, eventually reaching 121 degrees Fahrenheit (49 degrees Celsius) in British Columbia on June 29.

These records are not surprising, however; Scientists have long predicted that global warming will lead to a steady rise in temperature. But the extreme heat wave in June revealed a new concern: The record for high temperatures set in North America not only surpassed the previous record, it shattered it completely. Peter Stout, a climatologist at the Met Office, told the BBC that during the heat wave, temperatures in several cities in the United States and Canada were more than 7 degrees Fahrenheit (4 degrees Celsius) higher than previous records, that he was much older. than expected. The
data “tells us that changes in the average climate not only lead to a rapid rise in extreme temperatures, but also a rapid rise in abnormal extreme temperatures,” Stott said.
