Spring Floods May Increase This Year’s Gulf of Mexico Dead Zone

To develop an earlier prediction of the size of the Gulf of Mexico “dead zone” this summer, NOAA’s National Weather Service and National Ocean Service combined data from the National Hydrologic Assessment U.S. Spring Flood Risk Outlook with knowledge of soil saturation and typical weather patterns throughout the Mississippi watershed this year. Based on estimates of flood risk, snow pack, […]

Extreme Weather: A Mixed Bag for Dead Zones | WRI Insights

This post was co-authored with Bob Diaz, a WRI partner and professor at the Virginia Institute of Marine Science. This year’s extreme weather events—a warm winter, even warmer summer, and a drought that covered nearly two-thirds of the continental United States—has certainly caused its fair share of damages. But despite the crop failures, water shortages, […]
