But the latest USGS research, published in the Climatic Change journal, announces that the Bay's water temp has risen more than 2.5 degrees F between 1960 and 2010. And that does not even include the years since then, with 2014 the hottest year on record so far. Air temps during that same 50 year period rose less than 2 degrees F, so obviously the Bay's waters retain the heat.
One major result of warming waters is increased eutrophication, a fancy way of saying too much nutrients in the water. Animals and plants used to one level of nutrients may move upstream in freshwater or up the Chesapeake. Invasive plants may also find an environment that they prefer.
