How does tree rings show climate change
Webrepresent one year of growth. Tree ring records can go back hundreds to thousands of years, depending on when the tree lived and how old it was. Because tree rings are sensitive to local climate conditions such as precipitation and temperature, they give scientists some information about an area’s past local climate or “micro-climate.” For 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.
