Ice cores from Antarctica, from Greenland, and from a number of smaller glaciers around the
world yield a wealth of information on past climates and environments. Ice cores offer unique
records on past temperatures, atmospheric composition (including greenhouse gases),
volcanism, solar activity, dustiness, and biomass burning, among others. In Antarctica, ice
cores extend back more than 800,000 years before present (Jouzel et al. 2007), whereas.
Greenland ice cores cover the last 130,000 years
