Wetlands have role in methane production

A study by a University of Guelph researcher, published in Global Change Biology, says wetlands are the likely source of a recent and surprising increase in emissions of methane.

Eat less meat, reduce climate change gases

The executive summary of a European study, "Nitrogen on the Table," says if Europe reduced its meat consumption, it "would reduce nitrogen air and water pollution, and greenhouse gas emissions, while freeing up large areas of farmland for other purposes such as food export or bioenergy."

Study casts doubt on corn stover as biofuel feedstock

Using corn residues - stalks, husks and cobs - to make biofuels appears to create more carbon dioxide over their life cycle than the target set by federal standards, says research at the University of Nebraska.

Food quality dips as greenhouse gases increase

Science Daily says a field test conducted by the University of California-Davis "has demonstrated that elevated levels of carbon dioxide inhibit plants' assimilation of nitrate into proteins, indicating that the nutritional quality of food crops is at risk as climate change intensifies."
