Corn Alv
Exploratour 04: Greenhouse gas bound in stone

Beschreibung

The impressive dolomite rock of Corn Alv is actually a greenhouse gas bound in limestone. Some of the material for the calcareous shells was chemically formed by microorganisms 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 in Corn Alv. The same amount of CO2 stored in Corn Alv is blown back into the air by Switzerland in 2.5 years by burning oil, gas and coal.
