What is it about?
Tree-growth responds to changes in climate, and a really old tree can show a sample covering centuries. Ususally, tree-ring properties (annual ring widths, for instance) are used as a place-holder for growing conditions. But trees may not record the climate information in a simple, linear way. Often it depends on where the tree is growing. Especially tough conditions for a tree forces the rings to respond clearly to climate change. Our paper investigates a mathematical method for relating tree-ring properties to climate information in order to help the use of such data in climate research.

Why is it important?
It helps scientists better use expensive tree-ring data for climate studies.
