Can snow resorts survive climate change? It depends how much money you have

But it’s a costly process that draws on a lot of electricity and water. Since 2007, Perisher has spent over $22 million on improving and expanding the resort’s snowmaking system.

“Investment in snowmaking technology continues to improve. It’s reducing its energy consumption, water consumption and can make snow at higher temperatures,” Hackworth said. “The number of operating days has never ever been higher than it is now. In the snow industry, before snowmaking, snow wasn’t a guarantee.”

Victorian Mt Buller ski resort spokeswoman Rhylla Morgan said the facility had invested in snowmaking infrastructure for decades because reliable snow underpinned most of the winter business on the mountain.

“Mt Buller led the way introducing Australia’s first snow-factory in 2017 with several resorts immediately following suit,” Morgan said

She added the facility, along with many others, relied on a range of technology “to provide predictable snow cover in an increasingly less predictable climate”.

“Australian alpine areas are keenly focused on the challenges of climate change and are adapting all aspects of operations to reduce emissions and carefully manage resources to ensure we can continue to welcome guests to enjoy winter alpine experiences for many years to come,” Morgan said.

But as climate change worsened, the window to make snow would become narrower, said Climate Council research director Dr Martin Rice.

In NSW, a report prepared by the government in 2019 found lower elevation locations might not be suitable for making snow in the future as there could be a more than 20 per cent reduction of suitable snowmaking conditions for 2020 to 2039 relative to 1990 to 2009. By 2060 to 2079, this could hit 60 per cent relative to 1990 to 2009.

“Essentially, climate change is making it increasingly hard for ski resorts to function at their best. Resorts can’t just rely on [natural] snow,” Rice, also a keen skier said.

He said water availability would also become an issue for ski resorts. Declining resources combined with higher temperatures would create complications about how water was shared among the agriculture industry and conservation and fire protection efforts.

Rice said the cost of making artificial snow would only become more expensive as climate change worsened. In many cases, resorts had begun to diversify and adapt their tourism to focus on year-round activities such as mountain biking and hiking trails in warmer weather.

“If we are going to protect our winter sports, we need to reduce greenhouse gas emissions. Failure to do so could end the run for the beloved ski season,” Rice said.

What are we likely to see this season?

While snow conditions are expected to vary from year to year and some seasons, Australia could see a fairly snowless season this year if current weather patterns in the Pacific and Indian oceans continue. As ocean temperatures warm in these regions, they will drive warmer and drier conditions over the mainland this winter. Below-medium rainfall is very likely for Australia between June and August.

It’s not good news for snow resorts. Weatherzone said the average snow depth at the official Snowy Hydro measuring station at Spencers Creek was about 198cm, but this average dropped by about 36 centimetres during an El Nino occurs, and there was a slightly greater loss when El Nino and a positive Indian Ocean Dipole occurred together.

The combination of both these weather patterns has happened just eight times since 1960, but it could occur again this year.

As we look forward, snow seasons in NSW and the ACT will be warmer. The number of cool nights in the area is expected to decline as well.

Less snow will also affect the suitable habitat for small mammal species in NSW and Victoria. Foxes have become more common at higher altitudes as the climate has warmed. And as snow cover declines, native animals are becoming easier for foxes to find.

In Victoria, snow cover has diminished by about 50 per cent since the 1960s.

Under a high-emission scenario, Victorian alpine areas are also projected to have a 35 to 75 per cent decline in snowfall by the 2050s, data from the state government shows. There are concerns that as snow depths decline, so will the number of visitors which would greatly affect the local economy.

Victoria’s northern resorts of that is Mt Buller, Mt Stirling, Mt Hotham and Falls Creek are projected to have adequate snow to support winter snow activities in the next 20 to 30 years with the help of snowmaking. The southern resorts, Mt Baw Baw and Lake Mountain, should have adequate snow to support winter snow activities in the next 10 to 20 years.

Perisher did not respond to a request for comment. Thredbo said they were two weeks out from snow season and were too busy to talk.
