More than half of former host cities for the Winter Olympics will be too hot(deal) with such games by the end of this century. That is the(predict) of a recent study.
It's not just the Olympics that are at risk now. "The world of winter sports is changing as the global climate continues warming," says Daniel Scott,climate-change researcher in Canada. He led a team of researchers,used math to predict how winter conditions will have changed by February 2050 and 2080. February is the month when the Olympic winter games are(typical) played．
Scott and his team forecast temperatures and snow cover for the 19 cities that have already hosted Winter Olympics, and two(addition) cities: PyeongChang, South Korea, and Beijing, China, where the 2022 Winter Olympics will be held.
Scott's team(begin) with looking at historic winter conditions, and then used computer models to predict conditions in the future.(they) model predicted that by 2050, the average February temperatures in past Winter Olympic host cities will rise by 1.92.1 degrees Celsius. These temperatures can affect the quality of snow, thus(increase)the chance of accidents.
