Climate Change to Fuel More Toxic Algal Blooms, Dead Zones

Heavier rainfall linked to rising temperatures could substantially increase the volume of agricultural runoff flowing into waterways, triggering toxic algal blooms, according to new research.

A study published Thursday in the journal Science finds that heavier rainfall could increase nitrogen runoff in U.S. lakes, rivers and streams by 19 percent by the end of this century.

Last year, heavy rain caused an algal bloom in southern Florida that led the governor to declare a state of emergency, while a 2014 algal bloom contaminated the water supply in Toledo, Ohio.

"When we think about climate change, we are used to thinking about water quantity—drought, flooding, extreme rainfall and things along those lines," Anna Michalak, professor of global ecology at the Carnegie Institution for Science in Stanford, California, and an author of the study, told the New York Times.
