LANSING, Mich., Oct. 25 (UPI) -- Small marine organisms reacting to warmer oceans may dramatically affect the climate by the end of the 21st century, Michigan State University researchers say.
Warmer oceans will cause populations of marine microorganisms called phytoplankton to thrive near the poles but shrink in equatorial waters, they said. Since phytoplankton play a vital role in the food chain and the world's cycles of carbon, nitrogen, phosphorous and other elements, a drastic drop in their numbers could have measurable consequences for Earth, an MSU release said Thursday.
