Global warming is threatening ski resort company throughout the world. In 2023, Europe and the U.S. experienced the hottest winters on record, resulting in the early closure of many ski resorts. Likewise, in the US, ski season is now practically a week shorter compared to the early 2000s.

A study predicts that by 2050 ski season in the US may be 14 to 62 days (2 months) much shorter depending on the emission levels. This would make ski resorts economically unviable in numerous parts of the nation..
In the middle of these tough circumstances, synthetic snowmaking has emerged as a hero for the ski industry. Presently, about 95 percent of all ski resorts worldwide make their own snow to remain feasible..
Nevertheless, artificial snowmaking is an energy-intensive process, requires big volumes of water, and causes emissions..
” Ironically snowmaking includes more CO2 to the environment and is making the climate issue even worse,” Marie Cavitte, an expert on glaciers and climate change, told the BBC..
So can this option work in the long term?
How do ski resorts produce synthetic snow?

The lots of issues with synthetic snow.
As our worlds average temperature is crossing the 1.5-degree Celsius mark above the Industrial Age average, snowfall is ending up being progressively limited with each passing year. In between 1955 and 2022, snowpack in the western US fell by a staggering 23 percent.
According to an estimate, this considerable water need of ski resorts is predicted to increase by 80 percent in the next 70 to 80 years. This might cause water lack and water-related conflicts in areas where such resorts operate..
The ski market has actually been losing numerous countless dollars in profits due to the reduced snow season, leaving them no choice however to resort to artificial snowmaking..
” Operating snow guns takes energy. If that energy is fossil-fuel-based, which is extremely likely, then making snow is contributing even further to energy-related emissions. The really generation of synthetic snow ends up being part of the energy problem,” a report from the American Chemical Society stated.
These sustainable sources have helped them lower both their energy cost and emissions to some extent. Wind and solar energy have a huge upfront cost. Even after bearing the cost, ski resorts still need standard energy sources to continue their operations when there is not enough sunlight and wind, which is often the case in winter season.
In ideal conditions, a snow cannon can spray 150 gallons (560 liters) of water per minute and produce big mounds of snow measuring 200 to 300 feet (60 to 90 meters) in diameter.
The procedure includes pumping cold water (somewhat above 0 ° C )into a snow gun or snow cannon at high pressure. The snow gun then sprays the water up in the sky approximately a height of 35 feet (10 meters)..
Furthermore, synthetic snowmaking in Canada alone includes over 130,000 lots of CO2 to Earths atmosphere every year. This emission contributes to further warming of the planet, decreasing natural snowfall and making ski resorts more based on synthetic snow..
The scientists declare that in the future their method might allow ski resorts to utilize snow weapons throughout the year. Even this method does not promise a complete option..
For now, the future of ski resorts and our warming world seems unpredictable..

This would lead to the downfall of a multibillion-dollar market that uses countless individuals across the globe. A report recommends that as of 2023, there are over 80,000 staff members in the ski and snowboard resorts in the US alone..
” When they take them (the blankets) off, theres always pieces of plastic that are left which pollute the glacier and surrounding land,” Cavitte said..
Snowfall happens when the water vapors within the clouds freeze and turn into ice crystals. As the temperature level drops even more, these crystals stay with each other, grow larger, and kind snowflakes..
The gun also releases cold compressed air together with water. This air turns the water droplets into snow before they fall to the ground. The artificial snow is ready..
However, ski resorts need more than water to produce snow. They also require energy to power their snow weapons and other equipment..
When the resort is closed, another solution is to utilize UV-resistant blanket guards to cover the snow. Such blankets can decrease snow melting by approximately 70 percent. They can likewise minimize the water and energy consumption of ski resorts by reducing their reliance on synthetic snow..
A study focusing on snowmaking-related energy consumption in Canada exposes that ski resorts in the nation use 478,000 megawatt-hours of electricity annually. This much energy can power 17,000 homes for a whole year.
For example, its still unclear whether the mineral will secure the soil and plant life from the chemical toxins discovered in synthetic snow. Plus, it will be another 3 years before the technique is all set for testing in real-world settings..
Whats even worse is that the layers of artificial snow can damage plants, microbes, and the soil below them. Because of the anti-freeze representatives and different other chemicals utilized in the snowmaking procedure, this is.
During laboratory tests, they included an unique mineral to water that enabled them to produce synthetic snow at temperatures around one to 1.5 degrees higher than conventional approaches and at 30 percent less cost..
Traditionally produced artificial snow damages the environment and is certainly not a sustainable option. Nevertheless, without snowmaking, a big number of ski resorts around the world would close down.
So is there a method resorts can continue to have adequate snow for the ski season without harming the environment?.
An average ski resort requires about 300 million liters of water to produce all the snow needed throughout a ski season. This is roughly over 700 times the annual water intake of an average family in the United States.
Tiny snowflakes clump together and form heavier snowflakes that ultimately fall under the influence of gravity, leading to snowfall..
There are some solutions, but are they enough?.
Artificial snow melts gradually compared to natural snow (due to the fact that of its higher density). It deprives plants of light and oxygen for prolonged durations. This delay likewise adversely affects the water table and biodiversity in an area.
Scientists from the Barcelona Institute of Materials Science (ICMAB-CSIC) and FGC Turisme are presently working on a snowmaking technology that assures to produce artificial snow with less resources and at temperature levels above 37 ° C.
Due to the fact that there are some promising options to the problem however none of them fix all the obstacles associated with synthetic snow, the brief answer is yes and no. For example, some resorts have begun to utilize solar and wind energy to power their snow weapons.
In locations where natural snowfall is already scarce, you d still have to utilize artificial snowmaking. Some specialists likewise alert that these snow shields might also release microplastics and other contaminants into the ground.
The process is highly depending on natural conditions. It just works when the ambient temperature is below 37 ° C, air is dry and cool at 20 percent relative humidity. Otherwise, little or no snow will be produced..
Thanks for your feedback!
Artificial snow melts slowly compared to natural snow (because of its higher density). Another service is to utilize UV-resistant blanket shields to cover the snow when the resort is closed.
” Operating snow guns takes energy. If that energy is fossil-fuel-based, which is extremely most likely, then making snow is contributing even further to energy-related emissions. The extremely generation of artificial snow becomes part of the energy problem,” a report from the American Chemical Society mentioned.
