The Cooperative Institute for Climate Applications and Research evaluates, understands, and predicts
climate variability and change through the collection and
analysis of modern and paleoclimate data and the use of Earth
System models. We provide climate information to society through
education and the development of applications and tools for
assessing climate-related risks.

The causes of these droughts and pluvials are unknown. We have only a murky idea of what is in store in the greenhouse future, but if we can understand the late Holocene hydrological history we will be in a better position to predict and understand future changes in hydrological conditions which could have important consequences for water resources, crops, and rangeland…
