Climate change scientists know that plants can’t grow larger with extra carbon dioxide unless they also have nitrogen. But a new study coauthored by a Flagstaff ecologist shows fungus can help plants get around that limitation.


In 2015 the EPA issued a Clean Power Plan directing states to limit carbon dioxide emissions from power plants. Under the plan, for example, Arizona will need to cut annual carbon emissions from 40 to 30 million tons by 2030.
