Gabriel Yvon-Durocher and Guy Woodward have found a predicted 4°C rise in global temperatures by 2100 might lead to a 13 per cent fall in ecosystems' ability to absorb carbon dioxide (CO2) from the atmosphere. Guy Woodward said: “We found dramatic changes in the type and number of species in cold streams compared with the warmer ones. It was notable that fish and other larger predatory animals were absent from the coldest streams.” Reported in Red Orbit and Queen Mary News.
