Exploratour 04: Treibhausgas in Stein gebunden

The impressive dolomite rock of Corn Alv is actually a greenhouse gas bound in limestone. Part of the material for the calcareous shells has been chemically formed by small organisms from carbon dioxide gas (CO2) and other elements such as calcium and magnesium.

CO2 is largely responsible for the greenhouse effect and thus global warming. It took about 20 million years to deposit the amount of limestone of Corn Alv. Switzerland will blow the same amount of CO2 stored in the Corn Alv back into the air in 2.5 years by burning oil, gas and coal.
