Paleoclimate the history of climate change

Photo courtsey: NOAA.gov

Abstract: Present discussions on climate change are based on data that is gathered from studies conducted on coral cores, ice cores, tree rings, pollen, sediment from oceans and lakes, varves, pack rat middens and other indicators that are present in nature. Once past climates are determined it is possible to draw inferences and project changed regimes.
