The National Science Foundation has funded a study to determine past climates by studying tree rings. Environmental students from Arizona studied bristlecone pine trees to determine aspects about the Earth´s climates during the Paleo age. The study of tree growth rings to understand Earth´s past climate is called dendrochronology. As each year passes, trees add growth rings around their trunks. These dendrochronologists study these rings to gain all sorts of information not only...
