Why use ice cores? | How do ice cores work? | Layers in the ice | Information from ice cores | Further reading | References | Comments | Why use ice cores? Ice sheets have one particularly special property. They allow us to go back in time and to sample accumulation, air temperature and air
Ice cores are the time machines that allow us to investigate past climate. They preserve actual bubbles of air that mean that we can look at past concentrations of greenhouse gases in the atmosphere. They allow us to reconstruct past temperature and precipitation changes, and help us understand relationships between the composition of the atmosphere

How much ice is there in Antarctica? And if it were to melt, how much would global sea levels rise, and how quickly?

A paper in this weeks’ Nature by Mulvaney et al. 2012 suggested that the climate around the Antarctic Peninsula has varied extensively over the Holocene. This data is derived from a 363.9 m ice core from the Mount Haddington Ice Cap on James Ross Island.
