Vegetation and soil are currently slowing down global warming by absorbing about a quarter of human emissions of carbon dioxide (CO2). This land carbon sink is believed to be in part due to increases in photosynthesis. This new study in the journal Nature shows that doubling of the CO2 concentration in the atmosphere will cause global plant photosynthesis to increase by about one third. As well as its role in the climate system, photosynthesis also provides the primary food-source for life on Earth. The study therefore has relevance to the future health of ecosystems, as well as to the challenge of slowing climate change. The research was carried-out by scientists from the German Aerospace Center (DLR) and the University of Exeter in the UK, in a collaboration supported by the European Union through the CRESCENDO project. http://crescendoproject.eu/doubling...scientists-conclude-wenzel-et-al-2016-nature/ Interesting. But I wonder what would happen if temperatures rise due to increased CO2? Doesn't photosynthesis shut down when temperature is too high?
