Palaeoclimate: Windows on the greenhouse.

The article offers information on the research conducted by palaeoclimatologists on the implication of concentrations of stable isotopes and trace elements to climatic changes in Antarctica. Researchers believed that such factors infer changes in climate long before they themselves were on the scene. Members of the European Project for Ice Coring in Antarctica (EPICA) collaborated and gathered valuable information including atmospheric gases trapped and preserved in ice cores extracted from the Earth's polar regions. Such information provides scientists with an overview of the cycling of greenhouse gases such as carbon dioxide and methane. Discussed are the details of the experiment undertaken by palaeoclimatologists.
