Severe weather study: America’s heat wave would have been ‘virtually impossible’ without climate change – Wikipedia

According to a study, an unprecedented heat wave in the western United States and Canada would have been “virtually impossible” without climate change. “There is absolutely no doubt that climate change has played a critical role here,” climate researcher Frederic Otto of the University of Oxford told a news conference on Wednesday.

Global warming caused by greenhouse gases has increased the likelihood of a heat wave in the United States at least 150 times.

For the study by the World Weather Research Group (WWA), scientists compared historical climate observations with today’s weather. Thus, the values ​​measured in Canada and the United States are so extreme that they should only occur once every thousand years.

If the Earth continues to warm by up to 2 degrees Celsius, which it will be with current emissions over the next few decades, these heat waves could occur every five to 10 years and be about one degree hotter.
