Carbon Dioxide Spurs Sickness Scare At Livonia SchoolMultiple students became ill at a Livonia Middle School, where fire officials say there were slightly elevated levels of carbon dioxide.
MTU: Trees Finding The Nitrogen They Need Even When CO2 Is SupersizedA 10-year study that intentionally exposed trees to higher levels of carbon dioxide and ozone found that the trees managed to scrounge enough nitrogen to use the additional CO2 -- without causing nitrogen levels in the soil to fall. Instead, leaf litter and other organic matter decomposed more quickly, making more nitrogen available.
UM Study: Global Warming May 'Reroute' EvolutionRising carbon dioxide levels associated with global warming may affect interactions between plants and the insects that eat them, altering the course of plant evolution, research at the University of Michigan suggests.
