ScienceDaily: A new study from the University of Exeter, published in the journal Ecology Letters, found that phytoplankton -- microscopic water-borne plants -- can rapidly evolve tolerance to elevated water temperatures. Globally, phytoplankton absorb as much carbon dioxide as tropical rainforests and so understanding the way they respond to a warming climate is crucial. Phytoplankton subjected to warmed water initially failed to thrive but it took only 45 days, or 100 generations, for them to evolve tolerance...
