The Gulf of Mexico Hypoxia Task Force, a collaboration of state, federal and tribal agencies charged with controlling fertilizer pollution, told Congress last fall that nitrogen loads in the Mississippi River basin decreased 23% from the baseline period to 2021.
But the five-year running average – which accounts for extremely wet and dry years more common with climate change – tells a different story. By that measure, nitrogen is only slightly below baseline and well above the 20% target. Phosphorus loads worsened since the baseline period.
The oxygen-deprived ‘dead zone’ in the Gulf is predicted to be 5,827 square miles this summer, 5% larger than average, according to a forecast last week by the National Oceanic and Atmospheric Administration. Two long-time Gulf researchers predict a smaller ‘dead zone’, but only because of warming ocean temperatures, not because of progress reducing nutrients in the Mississippi River basin. - Investigate Midwest

The Gulf dead zone is still big and dead
There's been no real progress. Big Ag, among others, has seen to that.
