Warmer Temperatures INCREASE Phytoplankton Biodiversity and Photosynthesis

Warmer temperatures increase biodiversity and photosynthesis in phytoplankton, researchers at the University of Exeter and Queen Mary University of London (QMUL) have found. Globally, phytoplankton -- microscopic water-borne plants -- absorb as much carbon dioxide as tropical rainforests and so understanding the way they respond to a warming climate is crucial.

The groundbreaking study, published in the journal PLOS Biology, was carried out over five years using artificially warmed ponds that simulated the increases in temperature expected by the end of the century.

The researchers found that phytoplankton in ponds that had been warmed by four degrees, had 70% more species and higher rates of photosynthesis, and as a result, have the potential to remove more carbon dioxide from the atmosphere.
