Average rings represent average climate water deficit, plant's evaporative demand that exceeds soil moisture during 1950-2000. For every 4% decrease in annual climate water deficit the rings are darker and further apart, for every 4% increase in climate water deficit, the rings are lighter and closer together. In the 2090s climate water deficit will average 16% more than last century. For more info see technical notes.
