A new subject field has see that the figure of cities capable of hosting the Winter Olympics could be trim back to just one by the remnant of the 21st one C if   ball-shaped emissions of greenhouse gases are not dramatically reduced . This comes as the current Winter Olympics being held in Beijing makes history as the first Winter Olympics ever held withalmost 100 percentage contrived snow .

The study , release inCurrent Issues in Tourism , look at climate data from the 1920s until today , as well as succeeding mood change models for afterward in this century , including where emissions goals are hit and drop .

“ Climate change is altering the geographics of the Winter Olympic Games and will , alas , take away some host city that are famous for winter athletics , ” Robert Steiger of the University of Innsbruck in Austria say in astatement . “ Most boniface placement in Europe are projected to be borderline or not reliable as early as the 2050s , even in a low emission future . ”

They also asked current winter sports athletes to assess their preferred condition for Olympian sport Alpine Skiing , Nordic Skiing , Freestyle Skiing , Ski Jumping / Nordic Combined , Alpine Snowboarding , and Freestyle Snowboarding . They were asked to   rank a series of climatic conditions   ( e.g. fog , smart powder snow , chemically treated snow , icy surface , wind ) on a scale from   unacceptable to " ideal for peak functioning , condom , and fairness " , as well as the ideal temperature for vie in their sportswoman , and temperature at which point they would think insecure and unfair .

“ We wanted to understand from the athlete ’s perspective what clime and snow conditions made competitor fair and secure , " Natalie Knowles , former Canadian skier and current Ph.D. pupil who was involved in the study , enjoin in astatement . " And then influence which Olympic hosts could furnish those conditions in the future . "

The probability of unfair and unsafe experimental condition increase under all future mood alteration scenarios , according to the cogitation . However , if we stick to the Paris Agreement the effects can be importantly mitigated .

" In a low emission future ordered with a successful Paris Agreement , only 13 of 21 premature host location ( all in the Northern Hemisphere ) would stay on reliable for blow sports competitions in the 2050s and 12 in the 2080s , " the squad publish in the survey .

" The encroachment of a high emission scenario was far more pronounced , scale down the number of climatically reliable locations to 10 in the 2050s and 8 in the 2080s . The forecast for the Paralympic Winter Games , which pass off in March after the Olympics , was far worse . "

In one high emission scenario , only one city remains workable to host the Winter Olympics : Sapporo , Japan .

" The high emission tract result in a very unlike upshot for the power to reliably return mediocre and good experimental condition for snow sports at Olympic Winter Games locations , " the authors write . " By mid - century , the figure of authentic hosts declines to four ( Lack Placid , Lillehammer , Oslo , and Sapporo ) and by the end of the century only one localization rest reliable ( Sapporo ) .

The   main issue   of comeliness put up by the athletes related to the quality of the snow , include thedangers of unreal snow , while most safety concerns rise from higher temperature affecting athletes and the Baron Snow of Leicester .

" Too warm : body is too blistering – difficult to build tensity , fatigue – high hazard of injury   …   equipment ( impacted ) in general , " one slalom skier told the investigator . " But mainly boots get too soft   – no right control over the ski – serious ! "

The squad   found that 89 percent of the winter athletes they surveyed already think the clime crisis isimpacting competition conditions , while 94 percent fear it will impact the futurity of their sports .

“ No sport can scat the impact of a changing climate , "   Daniel Scott , Professor of Geography and Environmental Management at the University of Waterloo , Canada , said . " Achieving the Paris Agreement butt is vital to save snow sports as we make out it and ensure there are plaza across the world to host the Winter Olympics . "
