The precursor1 to the Winter Olympic Games was held in 1901， just five years after the first Summer Olympic Games in 1896. Known then as the Nordic Games and held initially2 in Sweden， this cold weather competition became so popular that it began moving from country to country and grew into one of the most-watched events in the world. The 2014 Winter Olympics in Sochi， Russia， drew hundreds of millions of viewers， including more than half of the entire population of the United States. Soon， however， the Winter Olympics may struggle to find a city cold enough to host the games.
A team of researchers led by Daniel Scott， a geography professor at the University of Waterloo in Ontario， has collected climate data from previous Winter Games and applied current climate change models to the historical information. By predicting future winter weather conditions， Scott and other researchers posit3 that by 2050， nine of the prior4 Winter Games locations will not be cold enough to ever host the competition again.
Although the research was originally published in 2014， it was recently updated to include the 2018 Winter Olympics in PyeongChang， South Korea， and the 2022 Winter Olympics in Beijing， China. Scott’s team used rising global greenhouse gas emissions5 projections6 to estimate7 an increase of 2.2 degrees Celsius by 2050. Using this model， Chamonix， France， the site of the first official Olympic Winter Games in 1924， would have an increase of 3 degrees Celsius by 2050， making its snowfall and temperature too unpredictable to make sure it could host the Winter Games.
A warming climate may affect not only future Winter Olympics， but athletes’ abilities to train. In the United States， for example， warm weather is predicted to cut the length of ski and snowboard seasons by half. This is expected to occur by 2050. By 2090， the current length of ski and snowboard seasons will be reduced by 80 percent.
冬季奥运会的前身是在1901年举办的，就在1896年第一届夏季奥运会的五年之后，当时被称为北欧运动会，最初是在瑞典举行的。而这个寒冷天气里的比赛变得非常受欢迎，开始从一个国家传到另一个国家，并发展成为世界上最受关注的赛事之一。2014年俄罗斯索契冬奥会吸引了数亿观众，其中包括美国一半以上的人口。然而，很快，冬奥会可能很难找到一个足够寒冷的城市来举办了。
加拿大安大略省滑铁卢大学的地理学教授丹尼尔·斯科特领导的一个研究小组收集了以往冬奥会的气候数据，并將当前的气候变化模型应用在历史信息上。通过预测未来的冬季天气状况，斯科特和其他研究人员推测，到了2050年，之前的九个冬奥会举办地将不够寒冷，无法再次举办比赛。
虽然这项研究最初发表于2014年，但最近更新了研究内容，包括2018年韩国平昌冬奥会和2022年中国北京冬奥会。斯科特的小组利用不断上升的全球温室气体排放量预测，估计到2050年气温将增加2.2摄氏度。在该模型下，1924年第一届正式冬奥会举办地法国夏蒙尼，到2050年气温将增加3摄氏度，使其降雪量和温度难以预测，无法保证能够主办冬奥会。
气候变暖不仅会影响未来的冬奥会，还会影响运动员的训练能力。以美国为例，据预测，温暖的天气将使滑雪和滑雪板季的长度缩短一半，这种情况预计会在2050年之前出现。到了2090年，现有的滑雪和滑雪板季的长度将缩短80%。
