North American Drought: A Paleo Perspective
http://www.ngdc.noaa.gov/paleo/drought/drght_home.html
- Global climate change is a topic of interest to all. This
site, created
- by the National Oceanic and Atmospheric Administration, looks
at
droughts in North America. Weather data is collected by using
fairly
modern technology, and by paleoclimatologists, which gather information
about climate by studying the rings of trees and sediment.
