Forest Canopy Color Reveals CO2 Uptake

When autumn rolls around, the leaf peepers come out in force. Armed with digital cameras, they record the most spectacular displays of fall foliage. Well according to a study in the journal Functional Ecology [Toshie Mizunuma et al., The relationship between carbon dioxide uptake and canopy colour from two camera systems in a deciduous forest in southern England ], those images may be more than just pretty pictures. They may represent a new way to monitor climate change.
