With droughts and downpours, climate change feeds Chesapeake Bay algal blooms

A study shows that weather patterns tied to climate change may increase the severity of algal blooms in Chesapeake Bay as extreme rainfall cycles flush larger amounts of nitrogen from fertilizer and other sources into the Susquehanna River. The researchers found that a spike in rainfall can increase nitrogen levels in the bay even if the amount of fertilizer used on land remains the same, leading to explosive algae growth that poisons humans and wildlife, and devastates fisheries.
