WebIce cores Scientists often use ice cores to detect changes in temperatures. When snow falls it traps air into the ice. When scientists take a core of ice it reveals the atmospheric gas... WebBut the major application of tree ring research is dendroclimatology: studying the relationship between tree growth and global climate change. The field really took off in the 1970s, when computers were able to develop and handle complex statistical models from tree ring data. This tree ring section comes from Alaska's northern treeline.
