'Most host locations in Europe are projected to be marginal or not reliable as early as the 2050s, even in a low-emission future,' one researcher said.
By the end of the century, just one of the 21 cities around the world that have previously hosted the Winter Games will still be able to"reliably provide fair and safe conditions for the snow sports program" unless countries can dramatically reduce their greenhouse gas emissions, according to theled by Canada's University of Waterloo.
"The International Olympic Committee will have increasingly difficult decisions about where to award the games, but the world's best athletes, who have dedicated their lives to sports, deserve to have the Olympics located in places that can reliably deliver safe and fair competitions," Ma said. "We wanted to understand from the athlete's perspective what climate and snow conditions made competition fair and safe, and then determine which Olympic hosts could provide those conditions in the future," said Natalie Knowles, a Ph.D. student and former Canadian skier who was involved in the study., according to three U.S. scientific agencies, and some scientists have worried that rising temperature rates are accelerating.
But the average February daytime temperatures of Winter Olympics host cities have already seen a steady increase. It has gone"from 0.4°C at the Games held in the 1920s to the 1950s, to 3.1°C at Games during the 1960s to 1990s, and 6.3°C in Games held in the twenty-first century ," a press release about the study said.
