Rising temperatures in the tundra of the Earth’s northern latitudes could affect microbial communities in ways likely to increase their production of greenhouse gases methane and carbon dioxide, a new study of experimentally warmed Alaskan soil suggests.

Water and land for growing crops are hard to come by in urban areas. Finding more sustainable methods for growing produce in urban areas would have enormous benefits. A pilot project by Georgia Tech’s Yongsheng Chen, a professor in the School of Civil and Environmental Engineering, aims to use wastewater from the campus to do just that.

Parks — especially linear parks — are emerging as viable and popular transportation corridors in cities around the country and connecting once-divided neighborhoods, according to a commentary published by Governing magazine Nov. 28.
