Climate Change Research: The Study of Ice Cores
November 20, 2011
Ice cores, drilled from the polar ice caps of Antarctica and Greenland most commonly, but also from places as diverse as Africa, Bolivia, China, Peru, Russia and even the United States are the most accurate means to proving a window into the paleoclimate record in Earth’s history, including past climatic and environmental conditions. Drilling miles […]
Paleo Proxy Data: What Is It?
September 29, 2010
By Martina M. Dewey A paleoclimatologist’s work is science focused on the climate of past ages. Proxy data is data that paleoclimatologists gather from natural recorders of climate variability, e.g., tree rings, ice cores, fossil pollen, ocean sediments, coral and historical data. By analyzing records taken from these and other proxy sources, scientists can extend […]
