Climate change threatens Winter Olympics and future snow sports, experts warn
Climate change is threatening the Winter Olympics and the future of snow sports by making conditions much more dangerous for athletes and participants, experts warned in a report published a week ahead of the start of the 2022 Winter Games in Beijing.
There are many different types สมัครสมาชิกสล็อต of games for all to marvel at. No bore.
The Beijing Games, kicking off on Feb 4, will be the first Winter Olympics to use virtually 100 per cent artificial snow by deploying more than 100 snow generators and 300 snow-making guns working flat out to cover the ski slopes.
"This is not only energy and water intensive, frequently using chemicals to slow melt, but also delivers a surface that many competitors say is unpredictable and potentially dangerous," said the report, written by researchers from the Sport Ecology Group at Loughborough University in England and the Protect Our Winters environment group.
Lying in naturally arid climates, the two co-host cities, Beijing and Zhangjiakou, could use an estimated 49 million gallons of chemically-treated water frozen through snow machines, according to the research.
Though China repeatedly claims to be using only natural rainfall and recycled water in snowmaking, there have been concerns that the high water utilisation rate would put additional pressure on the region's already scarce resources.
Natural snow is becoming less plentiful in some regions and water availability for snowmaking is falling as a result of climate change, putting the global snow sport industry at risk.
"Navigating erratic snow seasons and rapid melt of low level resorts are now the norm for many competitors," the research said.
