INTERNATIONAL JOURNAL OF TOURISM, TRAVEL AND HOSPITALITY LAW It is necessary to study the effects of climate change on snow cover and show that a decrease is expected due to climate change, in future years as in previous periods. As indicated previously, precipitation will be extreme with varying intensities depending on the region of the world. The mountainous regions are the most impacted (compared to the plains) by the phenomenon of the decrease in snow cover. The rise in temperature results in a reduction in snow cover. Snow at lower elevations melts faster due to rising temperatures. Under the two scenarios: one of the status quo and the other limiting the increase to 1.5 degrees, the temperature increases and the precipitation consists of rain, thus decreasing the snow cover of the mountains(Luetschg, 2005)28. The disappearance of the layer of snow generates difficulties at the economic and tourist levels. The consequences of global warming and in particular those concerning the disappearance of snow have a severe impact on ski tourism in Europe. A study shows that for Austria almost 50% of ski resorts would not be reliable for ski tourists(Steiger, 2019)29. The authors add that to face these problems of lack of snow, it would be necessary to think of the artificial snowing up and the increase of this one according to a value ranging between 32% and 45%. Although artificial snowmaking is a solution to this problem, which should take place in 30 years, this solution is costly in monetary and environmental terms. Artificial snowmaking requires a large quantity of water, the supply of which is itself in danger. In the context of the limitations of climate change and its consequences, water would be a resource to be favored and not to be used in the production of snow in greater quantities in 2050. On the other hand, the process requires energy production which is also quite expensive. Added to this is the skier's experience which will differentiate artificial snow from that which is natural. 3.2 Sea level rise Measured using a tide gauge, the sea level acts as a reference for evaluating and geographically positioning places.
