Olympic organizers have made climate variety a cardinal root at the current games — and for good reason . A sober up new study shows that by the 2084 Olympics , rising temperature will make it much unacceptable for most metropolis to host the summer biz .
Ina fresh commentarypublished in The Lancet , a team led by Berkeley researchers Kirk Smith and John Balmes monish that the future of the summertime Olympics is in jeopardy . Seventy years from now , only eight Northern Hemisphere city outside of Europe will be cool enough to host the games , with only three city in North America capable of serve as hosts .
The researcher arrived at this conclusion by developing a measuring , call the wet bulb world temperature ( WBGT ) , that combines temperature , humidness , heat radiation sickness , and wind . This tool was used in conjunction with two climate example to assess the viability of next host cities .
For the analytic thinking , only cities with at least 600,000 residents were considered , which is the minimal sizing required to host the game . Cities with elevation over a mile above sea level , such as Mexico City , were omit due to other limiting factor , such their thin , O poor air . The researchers also assumed that any venue with more than a 10 percentage chance of having to offset a endurance contest — a theme song result — on short bill would prevent that city as an Olympic prospect .
“ If you ’re go to be spending billions of dollars to host an event , you ’re going to want have a degree of certainty that you ’re not go to have to strike down it at the last moment , ” explained Smith in a argument .
Using this criteria , the researchers were able-bodied to identify only eight out of 543 cities outside of western Europe that would condition as “ low risk ” sites , including St. Petersburg in Russia , Riga in Latvia , Bishkek in Kyrgyzstan , and Ulaanbaatar in Mongolia . Shockingly , only three North American metropolis made the cut , namely San Francisco , Vancouver , and Calgary . Western Europe provide the great number of “ low risk ” city at 25 . Latin America and Africa neglect to produce a single practicable metropolis .
Looking further ahead into the 22nd Century , the researchers predicted that only four Northern Hemisphere city would be capable of qualifying : Belfast , Dublin , Edinburgh , and Glasgow .
The research worker correctly point out that work - arounds exist , such as consort the summertime plot indoors or rid of certain events that are n’t suitable for the heat . But that would dramatically alter the skin color and spirit of the game .
Talk about grim . As meter passes , and as the scourge of globose warming arrive into focus , it ’s vindicated that virtually every facet of human existence are conk to be affected .
