Japan's plan of cooling 2020 Tokyo Olympics venues with snow gets hindered due to low snowfall

The currently which has been currently hit badly by the COVID-19 epidemic is going to host the Tokyo Olympics which is going to start from July 24

Officials in Japan stated that their plan to use the snow collected from Japan's mountains for the cooling down of 2020 Olympics venues during the summer got hampered due to low snowfalls. The authorities in the Minami-Uonuma in Niigata prefecture on the north of Tokyo have been trying to collect snow and store them so that they can bring them by train to the Olympic football and basketball venues.

The project which is costing about 54 million yen ($490,000) will be carried out to cool down the buildings and also snowpacks will be given top the spectators who are approaching the venues. As the temperature around Tokyo has a tendency to rise to 40 degrees Celcius during summer, the organisers are also planning to use mist sprays and water stations for the refreshments of the attendees.

The city has only collected 1,400 cubic metres of snow

Ever since Alexander the Great enjoyed honey and nectar flavoured snow in the 4th century BC, the snow has been used to cool everything from food to fortresses. In Norway, Oslo airport uses snow stored during the winter for summer use to cool buildings. But Japan's lack of snow this year has forced a rethink.

"We had to change the snow-gathering site from last year to an area where we can expect more snow," Mutsumi Seki, the manager in charge of the project at Minami-Uonuma told Reuters. Still, the city has only collected 1,400 cubic metres (49,000 cubic feet) of snow, compared with 2,000 cubic metres (70,000 cubic feet) last year, when it tested the viability of the plan.

Snow depths this winter in Niigata, which usually boasts some of Japan's heaviest falls, are on track to be the lowest since records began in 1981, based on data on the JMA website. Maximum snow depths in areas along the Sea of Japan decreased by as much as 15 percent per decade in the years between 1962 and 2016, according to a Ministry of Environment study in 2018.

"The warmth in Japan is part of a much larger pattern of unusual warmth around the entire Northern hemisphere this winter," Professor Michael Mann, director of the Earth System Science Center at Pennsylvania State University, adding "this larger pattern of warmth is connected to human-caused planetary warming."

Masami Yashima, the manager of the Okushigakogen resort in Nagano next to Niigata, also believes global warming is behind the poor snowfall. "There's very little snow. About a third of what we get here every year," he said. "It's very painful."
