Out of 93 potential Winter Olympic and Paralympic Games host sites only 52 would remain climate-reliable for the Olympics and just 22 for the Paralympics if countries continue current climate policies, according to a new study by Canada’s University of Waterloo in collaboration with University of Toronto and University of Innsbruck researchers.

Photographs taken around Athens 10 years after the 2004 Olympic Games show a significant number of abandoned Olympic sites, including the Olympic Village. The Olympic baseball stadium in the Hellinikon Olympic Complex in Athens was also abandoned after the Olympics.
