Why can we infer the previous climate and environmental conditions from the tree rings of ancient trees?
The rings of a tree are one year old. If the weather is favorable, the trees grow normally and the annual rings are uniform in thickness; If there is a lot of rain and trees grow vigorously, the annual rings are particularly thick; If the dry matter dries up in a year, the growth of trees will be slow and the annual rings will be weak.
Tree rings are natural and no one can change them. According to this law of tree growth, scientists can calculate the climate change information of a region for ten to a hundred years.
