There's a big chance that the snow in The Alps might melt sooner than you think. In fact, it is predicted that if people will not change their carbon emission activities, the Alps might lose 70 percent of its snow by 2100. But, if people can keep global warming contained and be below 2°C, the snow would only be reduced to 30percent by the end of the century.
