US: Potatoes thrive under higher carbon dioxide levels

Although some plants may suffer under global climate change and increased carbon dioxide levels, potatoes appear to thrive. Under trials that simulated elevated CO2 levels, potato tuber yield was as much as 60 percent greater than from plants growing under current CO2 levels, according to a news release. The studies, conducted by an Agricultural Research Service group led by agricultural engineer David Fleisher, involved growing potatoes in two outdoor chambers that simulated long-term drought and increased CO2 levels.
