Climate change

Description:

The Earth's climate has not been constant over geological time. This record is contained in ice, which has built up as snowfall accumulated in distinct yearly layers. Pockets of air trapped between the snow crystals contain traces of past atmospheres, which in turn tell us about the climate at the time the snow formed. Glaciologists collect this record by drilling ice cores and then use sensitive chemical techniques to analyse the layers.
