Climate Change in the Austrian Alps 1971 1991 2002
The Austrian Alps The Austrian Alps are one of the great mountain range systems in Europe Take great influence on the European climate Diverse natural vegetation Heavily influenced by the Retreat of Glaciers
Greenhouse Effect
Retreat of Glaciers Causes: Increase in carbon dioxide (CO2) emissions, which accelerate global warming Impacts of glacier retreat: Snowline rise Local businesses (hotels, operators of ski-lifts etc.) might suffer from less tourism Extinction of alpine plants Extinction of animals Shortage of drinking water
Unfreezing of permafrost soil Icy layer that stabilises alpine ground („mountain glue“) Impacts of an unfreezing of permafrost soil: Increase in mudslides and avalanches (=snowslides) Alpine buildings might collapse http://www.youtube.com/watch?v=FcV9xiex5nI
Environmental Disaster More storms Increase in floodings
What should we do? Diminish carbon dioxide emissions and save energy by: using energy-saving lamps turning off electronic devices when they‘re not being used taking public transportation installing heat insulation eating less meat (methane) supporting sustainable energy (solar power, wind power, geothermal power)
Thank you for your kind attention!
