The future of the Olympic Winter Games in an era of climate change

The Olympic Winter Games (OWG) stands as a symbol of international cross-cultural exchange through elite-level sport. As a mega-event with a significant reliance on a specific range of weather conditions for outdoor competitions, the OWG have developed several technologies and strategies to manage weather risk. Can these climatic adaptations cope with future climate change? Based on an analysis of two key climate indicators (probability of a minimum temperature of <= 0 degrees C, and probability of a snow depth of >= 30 centimetres with advanced snowmaking capacity), this paper examines how projected changes to climate will impact the ability of the 19 previous host cities/regions to provide suitable conditions for outdoor competitions in the future. The results indicate that while the 19 former OWG hosts all have a suitable climate in the 1981-2010 period, only 11 or 10 (low-high-emission scenarios) remain climatically suitable in the 2050s, with as few as 6 in the high-emission scenario of the 2080s. The analysis reveals that climate change has important implications for the future geography of OWG host cities/regions as well as broader implications for participation in winter sport.
