With the Winter Olympics set to be held in Sochi, Russia starting February 7th, new reports are questioning whether the games will survive climate change in the future. A new study conducted by the University of Waterloo says that most of the cities that have already hosted the Winter Olympics may be too warm to host the events again. According to the study, only six of the previous Winter Olympics host cities will be cold enough to reliably host the games by the end of this century if global warming projections prove to be accurate.
