Tree Rings: A Type of Weather Data
May 8, 2012
By Penny Paugh Trees grow on every continent except Antarctica, and the rings they contain embody a record of climate change going back thousands of years. Each ring represents a single year’s growth, so not only can a ring count tell us how old a tree is, but they can also help reconstruct climatic history […]
The Economic Impact of Extreme Weather in the US
May 4, 2012
A team of social scientists and economists from Colorado and California recently completed a study on the United States economy’s sensitivity to weather variability: extreme heat, extreme cold, droughts, and floods.

Luisa Cristini, PhD, University of Hawaii at Manoa. [Note from the editor: This is the fourth in a series of blog entries that will focus on introductory topics in climate dynamics and modeling, and will be a great insight into the current understanding of the science.] Many characteristics of the climate are influenced by the […]
Climate change and drought in Australia
June 3, 2010
By Allyson Gorsuch Have you ever spent any amount of time on an island? If you have, then you know that the local population is acutely aware of winds, tides, precipitation, humidity, and all other weather conditions in general.
