Winter Olympics and Paralympics face reduced host options as the planet warms

Climate change is rapidly shrinking the number of reliable hosts for the Winter Olympics and Paralympics, say Canadian researchers studying how to adapt the Games as a new paper floats the idea of a unified event or multi-country hosts.

The study published Wednesday builds on recent research co-authored by the University of Waterloo’s Daniel Scott that suggested about half of a possible 93 locations could reliably host the Olympics in February by mid-century if global warming continues on its current trajectory.
