#Warming #Oceans and #Waterways #Threaten a Key #Human #Protein #Source
#Fish are #adapting to #hotter #temperatures in ways that are problematic for people. They are getting #smaller and #dying at higher rates as they #adapt to warming waters, researchers warn in a report released Thursday in the journal Science. This evolutionary change will #reduce #global fish #yields by one-fifth under current warming predictions, and up to 30 percent in high-emissions scenarios.
