Global emissions of ethane, an air pollutant and greenhouse gas, are on the uptick again. A team led by CU-Â鶹¹ÙÍø found that a steady decline of global ethane emissions following a peak in about 1970 ended between 2005 and 2010 in most of the Northern Hemisphere and has since reversed. Between 2009 and 2014, ethane emissions in the Northern Hemisphere increased by about 400,000 tons annually, the bulk of it from North American oil and gas activity.

Humans use fire for heating, cooking, managing lands and, more recently, fueling industrial processes. Now, research from the University of Colorado has found that these various means of using fire are inversely related to one another, providing new insight into how people are changing the face of fire.

Here’s a new recipe that might be good for the planet: Add sunlight to a particular nitrogen molecule and out comes ammonia, the main ingredient of fertilizer used around the world. The eco-friendly method of producing ammonia is described in a new study led by the Department of Energy’s National Renewable Energy Laboratory in Golden and involving CU-Â鶹¹ÙÍø.
