Short summary

Using information derived from tree-rings, we reconstruct possible combinations of past temperatures and precipitation amounts. This lets us put current changes in context and shows, for example, that the 1930s were likely the driest decade on record in central Kansas, while the late 20th century was likely the wettest period on record in the North American southwest.
