Zero-acreage farming, or ZFarming, is a new branch of agriculture involving production in or on urban structures. In scale, it's a small and new global trend but a potentially important one through which innovators are attempting to address some of the many issues we experience in urbanization.
Although much research shows there are significant differences in public opinion on climate change beliefs, national scale statistics conceal this heterogeneity. Using an approach known as multilevel regression and poststratification, a team of researchers finds significant variability in opinion on important climate-related issues and behaviors at all levels of comparison.
New research suggests there are significant differences in the pollution offset by an additional unit of wind power versus solar power. The evidence suggests environmental policy subsidizing renewable energy instead of addressing emissions directly is inefficient and unnecessarily costly.
