Scientists unlock Monte Rosa’s secret history

Scientists unlock Monte Rosa’s secret history
trefwoorden: Italië - ijs - romeinse tijd - klimaatverandering
Swiss and Italian researchers are digging near the summit of Monte Rosa on the Italian border in search of secrets locked deep within the ice.

Ice is a natural archive that can store a wealth of information about the past: volcanic eruptions, Sahara sand storms and nuclear tests carried out on the other side of the world.
“Anything that is emitted into the air will ultimately be captured in the ice as a result of precipitation,” says Professor Heinz Gäggeler of the Paul Scherrer Institute (PSI), one of the top scientific research institutions in Switzerland.
“The quality and consistency of the various glacial layers can take you back to the climatic situation of any given era.”
