Eco Tech: Nitrogen doped trees can fight climate change
Ecofriend — ... create a new sink for carbon dioxide. The Dark Side: While the results of the research seem promising, there are some scientists who believe that adding nitrogen to soil would result in nitrous oxide emissions, which is a far more potent greenhouse gas than carbon dioxide. Moreover, the technique works on only a few species of trees and to get any benefits we would have to plant entire forests made just out of those few species. Via: TreeHugger

"According to the US Energy Information Administration (EIA) estimates, in 2006 urban trees accounted for nearly all (90 percent) of the carbon sequestration attributed to the combination of urban tree growing, plus land-filled yard trimmings and food scraps."
