Increased Rainfall Resulting from Climate Change Could Exacerbate Toxic Algal Blooms

By Roberta Attanasio, IEAM Blog Editor

One of the main previsions of climate science is an increase in precipitation and extreme rainfall events, which may easily cause flooding and challenge water management.  The phenomenon finds its basis in the magnified evaporation caused by warming, resulting in the swelling of water vapor in the atmosphere. In this situation, when it rains, it rains a lot, as there is more vapor available to come down as rainwater. Rainwater may fall not only in large amounts but also in short, localized bursts, too quickly for the ground to absorb it. Sadly, these climate science forecasts are coming true. Although the relationship between global warming and increased precipitation is complex, there are no doubts about the marked increase in intense rainfall events, resulting in severe flooding throughout the United States and globally.
