At Cypress Mountain ski resort, director of operations Jeremy Wentzel has been eagerly waiting for a chance to fire up the snow guns.

The Vancouver ski destination has manufactured more than 81 acres of artificial snow for skiers and boarders to enjoy since opening for the season Dec. 7, but much of that was lost to rainfall and warm temperatures later in the month.

With cooler weather in the forecast, however, Wentzel said a prime opportunity to pump out fresh powder could be just around the corner.

B次元官网网址淲eB次元官网网址檙e just waiting for temperatures to fall slightly, because weB次元官网网址檙e getting very, very close to a pretty significant snow-making window,B次元官网网址� Wentzel said.

B次元官网网址淚t has been a challenge this Christmas period. But temperatures do generally get there eventually, and then you get to put on display what having a robust snow-making system can do for you.B次元官网网址�

Artificial snow-making B次元官网网址� which involves using machines, or B次元官网网址済uns,B次元官网网址� to spray a mixture of water and compressed air that then freezes into snowflakes B次元官网网址� has been used by the Canadian ski industry since its development in the 1950s.

But with climate change now posing an existential threat to an industry that depends on winter weather, snow-making is expected to become more important than ever.

A study by the University of Waterloo in partnership with the University of Innsbruck in Austria suggests snow-making production requirements by the Canadian ski industry will increase between 55 and 97 per cent by 2050, as climate change brings warmer winters and less natural snowfall.

In Ontario alone, for example, changing weather patterns due to climate change could shorten the average length of the ski season by up to 60 per cent.

Already, in an average winter, Canadian ski resorts produce an estimated 42 million cubic metres of machine-made snow.

But making snow is not as simple as hitting a switch and blasting flakes wherever and whenever you want them. For one, the weather must be cold enough for water to freeze, so all the snow-making capability in the world wonB次元官网网址檛 help in an extended plus-zero-degrees streak.

B次元官网网址淭here is a bit of a conundrum there,B次元官网网址� said Tara Lovell, spokeswoman for OntarioB次元官网网址檚 Blue Mountain Resort, where an exceptionally mild December meant a very limited number of runs were open over the holiday season.

B次元官网网址淚 would say that our (snow-making) system hasnB次元官网网址檛 been able to get up and running as much as we would have liked.B次元官网网址�

Snow-making is also expensive. It requires the installation of water pipes and pumphouses, hydrants and snow guns across significant swaths of terrain. This year, Blue Mountain committed to a B次元官网网址渕ulti-year, multi-million-dollarB次元官网网址� investment in snow-making infrastructure improvements that includes enhancing the systemB次元官网网址檚 automation capabilities, Lovell said.

These kinds of investments are meant to help the resort navigate increasingly erratic weather patterns, she added.

B次元官网网址淒ecades ago, you could kind of guarantee that winter will eventually come and we can make snow when itB次元官网网址檚 here. But now, those snow-making windows can come in the middle of the night for just an hour here, an hour there,B次元官网网址� she said.

B次元官网网址淪o the more efficient our system is, the better off we are at making sure weB次元官网网址檙e maximizing what we can, despite the volatility of Mother Nature.B次元官网网址�

But while snow-making may be the ski industryB次元官网网址檚 answer to climate change, it has also been criticized by activists for contributing to it. The University of Waterloo study found artificial snow production at Canadian ski resorts consumes 478,000 megawatt-hours of electricity annually and an estimated 43.4 million cubic metres of water.

And as the demand for artificial snow grows, so too will ski resortsB次元官网网址� demand for water and power.

Waterloo professor Daniel Scott said the sustainability of snow-making varies greatly from location to location, depending on the source of the water and how green the local electricity grid is.

He said the ski industry will need to ensure snow-making is being done in a responsible way B次元官网网址� in particular, limiting negative impacts on downstream watersheds and conflict with other water users.

B次元官网网址�(Snow-making) can be very unsustainable, or it can be very sustainable,B次元官网网址� Scott said.

For her part, Lovell said she believes there are few industries more concerned about sustainability than the ski industry.

B次元官网网址淚 canB次元官网网址檛 forecast what is yet to come when it comes to climate change, but we do see those changes happening,B次元官网网址� she said.

B次元官网网址淔or our business to be sustainable, we need to make sure that we can continue to provide a snow-related product to our guests, despite what weB次元官网网址檙e seeing and the trends that may be coming.B次元官网网址�

Back at Cypress Mountain in Vancouver, Wentzel said the resort likely would not have been open at all over the holidays if it didnB次元官网网址檛 have its snow-making system. He said making snow is a way for the ski industry to take back some control from Mother Nature.

B次元官网网址淪now-making has been a huge investment priority for us,B次元官网网址� he said.

B次元官网网址淚tB次元官网网址檚 a pretty big insurance policy for the mountain, because it allows you to manage your own fate, if you will.B次元官网网址�
