Climate change impacts

HideShow resource information
Evidence for recent climate change
Most popular resorts lie at relatively low levels... Around 30 years time the snow line will have risen by 300m and half of resorts in Europe will be forced to close by 2050
1 of 12
Lower level reponses
Tourists transported to higher resorts for skiing.... Artificial snow cannoned onto slopes (40% make own snow)
2 of 12
What have resorts had to do to keep business going?
Offer hiking, climbing and sledding
3 of 12
What are avalanches?
Masses of snow, ice and rocks that move downhill at speeds of up to 300kph
4 of 12
What is a loose snow avalanche?
This type of avalanche usually starts from a single point and involves loose, powdery snow, looks like an upside down V.
5 of 12
What is a slab avalanche?
Great theat to skiers. A thick layer of snow under stress and a number of triggers can cause it to break.Examples of triggers could be a storm or the weight of a person.
6 of 12
Avalanche cause - Heavy snowfall
Adds weight to earlier snowfall & creates distinct layers within the snow.
7 of 12
Avalanche cause - Steep slopes
Avalanches are more likely to occur on steep slopes in excess of 30 degrees
8 of 12
Avalanche cause - Tree removal
It enables avalanches to move and the roots bind the snow together
9 of 12
Avalanche cause - Temperature rise
Temperature rises can be associated with spring avalanches
10 of 12
Avalanche cause - Heavy rainfall
Lubricates slope and triggers avalances
11 of 12
Avalanche cause - Human factors
Off - piste skiing and other factors can cause avalanches
