The June heatwave was the most record-breaking in North America


The devastating heatwave that hit the northwestern United States and southwestern Canada in June was the “extreme summer heat” ever recorded in North America, says a new analysis from the non-profit research group Berkeley Earth. It is based on the magnitude of the heat waves or how much it was warmer than normal. Record temperatures in the area reached about 20 degrees Celsius (or 36 ° F) warmer than average in June.

Canada saved it the hottest temperature ever June, when the temperature in the village of Lytton in British Columbia was an amazing 49.6 degrees (121 degrees Fahrenheit). Typical temperatures in June are closer to 20-30 degrees (68-86 degrees Fahrenheit).

The consequences of this heat are shocking. Roasting temperatures fed the forest fires that burned 90 percent of Lytton. At least there were 570 heat-related deaths in Canada and at least 194 In the United States. Thousands of people ceased operations on call.

The heat wave at the end of June was “an event of 1000 years avasti hopefully,” according to preliminary data analysis National Oceanic and Atmospheric Administration (NOAA). The severity of the heat would have been “virtually impossible” without man-made climate change, both NOAA and stand-alone analysis from an international team of researchers found.

The entire northern hemisphere had the warmest June of all time averages. Nearly 4 percent of the Earth’s surface had record-high average temperatures in the first half of 2021, according to Berkeley Earth analysis. This is despite the cooling effect of La Niña. Looking at the first six months of the year, “nowhere has there been a record cold” has tweeted Robert Rohde, chief researcher at Berkeley Earth.

Globally, the likelihood of people like “more record-breaking” heat waves, such as those that wreaked havoc in the U.S. and Canada in June, is likely to increase. Events of long, record-breaking extreme heat are 2-7 times more likely this year than 2050 compared to the previous three decades. research published earlier this week. This estimate is based on a scenario where greenhouse gas emissions remain high today. There is still hope to avoid this future – but first humanity need to stop burning quite many fossil fuels.
