Researchers find increases in nitrous oxide emissions, outpacing global predictions
The term ''greenhouse gas'' is often used interchangeably with carbon dioxide, due to its prevalence in our atmosphere - more than 80 percent of all greenhouse gas emissions, estimates the Environmental Protection Agency. But another greenhouse gas, nitrous oxide (N2O), can have effects with far greater impact. And, according to a recent study, N2O emissions are increasing at a ''devastating'' rate, faster than predictions introduced by the Intergovernmental Panel on Climate Change. (2020-10-08)

Phosphorus deficit may disrupt regional food supply chains
Phosphorus-based fertilizer is essential in modern agriculture. In regions with high population growth, more phosphorus will be needed to produce more food. A new study shows that world regions with high population growth rates are also the regions with the highest phosphorus deficit. It also quantifies the environmental impact of a business-as-usual scenario in the phosphorus supply chain to 2050 and identifies alarming rates of pollution and greenhouse gas emissions associated with the phosphorus supply.
