Learning from the past

Article Abstract:

The magnitude of flooding can be affected by small changes in climate, as shown by a study of the past 5,000 years of the Upper Mississippi River tributaries. James Knox studied floods which went over the banks of the rivers and found that climatic cooling increased the flooding, such as at times preceding the Little Ice Age. This knowledge can help with current models of the dangers of global warming or other climatic changes.
