A large contribution to the study of greenhouse gases

Nitrous oxide, a greenhouse gas 300 times more potent than carbon dioxide, accounts for about six percent of human-induced climate change, but researchers don’t know where 30 percent its global emissions come from.

Now, a CGRER study, led by UI chemistry professor Vicki Grassian, sheds more light on that question.    Continue reading
