Global warming can erase the Olympics since 2085

Researchers have confirmed that global warming can make many big cities around the world become too hot to host the Summer Olympics in the coming decades.

The team concluded that, in just 70 years, only eight cities located in the Northern Hemisphere outside Western Europe will be cool enough to host Olympic Games competitions. This phenomenon will increase the difficulty for organizers to continue with their predetermined plans.

Researcher Kirk Smith from the University of California, Berkeley, said: " Climate change may be an obstacle for the Olympics to move forward . And the cause is not just because of rising sea levels."

Smith and his colleagues came to this conclusion after analyzing heat radiation, humidity, temperature and wind data from two separate climate models, focusing on two possible locations. Olympics. From there, they combined to create a model called the wetbulb global temperature (WBGT).

By using WBGT, the team predicted that temperatures in different large cities are located in the Northern Hemisphere in the coming decades. The criterion to choose is that the city must have a population of more than 600,000 - this is also one of the current regulations for a city to host the Olympics.

They then proceeded to see which city would fall into the 10% risk of canceling an outdoor marathon because of future unsafe temperature conditions.

Currently, this 10% criterion is used to select which cities will host the games, because the marathon exam is extremely dependent on weather conditions and the cancellation of this game will more or less affect up other games.

Smith added: "If you are planning to spend billions of dollars to host an event, you will want to make sure you don't want to cancel it at the last minute."

With all the criteria set, the team uses their model to consider which cities might not be suitable for organizing the Olympics in the future. They concluded that only 8 of the 543 feasible countries in the Northern Hemisphere could be suitable for hosting in 2085.

" These findings suggest that Istanbul, Madrid, Rome, Paris and Budapest, which are already competing cities for hosting the Summer Olympics in 2020 and 2024, will not like it," the group said. it is suitable to organize in 2085. Tokyo is a city that can ensure safety for the 2020 Summer Olympics will also become too hot to ensure safety for athletes ".

Cities will still be feasible for the organization to predict researchers including: Petersburg (Russia), Riga (Latvia), Bishkek (Kyrgyzstan), Ulaanbaatar (Mongolia), Calgary (Canada), Vancouver (Canada) , and San Francisco . In Western Europe up to 25 smaller cities can meet the weather conditions, but there are no countries in Latin America and Europe.

The team said that although these findings are looking specifically at future Olympic events, they also show how much global warming can impact our society.

Climate change can be an obstacle for the Olympics to move forward.

" Climate change will force us to change our behavior compared to what we are doing every day . This includes small actions such as letting children go out to play football or running," Smith added . more or less dramatically change the world ".

The research team is not alone in their conclusions. In May, an international team from researchers found evidence that climate change could spur a massive migration from the Middle East and North Africa by 2065 because then temperatures will reach. danger level.

But it is important that current studies are based solely on models. And much more research needs to be done before coming to a better perspective on concluding what the world will be like in the future.

Currently the Olympics are still taking place with quite a lot of exciting competitions and surely the organizers also have future plans for this event. The phenomenon of climate change is not necessarily the end factor of the game but it will certainly be something worth thinking about.
