An intensifying water cycle will likely cause dramatic increases -- nearing 20% by 2100 -- in the amount of nitrogen runoff in the US, according to a new study.
If climate change is not curbed, increased precipitation could substantially overload US waterways with excess nitrogen, according to a new study from Carnegie's Eva Sinha and Anna Michalak and Princeton University's Venkatramani Balaji published by Science. Excess nutrient pollution increases the likelihood of events that severely impair water quality. The study found that impacts will be especially strong in the Midwest and Northeast.
High-speed winds during a thunderstorm may cause trees around an electric grid to crash into the distribution system feeders causing an outage in that area. Currently, most utility companies diminish such accidents by scheduling regular tree-trimming operations. This effort is costly and is based on a rotational approach to different service areas, which may take months and sometimes years before all trees are trimmed.
As part of the Helmholtz Russia Research Group LaBeglo, UFZ researchers are studying the impact of climate change and environmental toxins on the lake's fauna. In a recent study, together with researchers from the Helmholtz Centre for Polar and Marine Research (AWI) and the University of Irkutsk, they addressed the question of how Baikal amphipods that fulfil important ecological functions in the lake react to pollutants in the water.
The early human techno-tradition, known as Howiesons Poort, associated with Homo sapiens who lived in southern Africa about 66,000 to 59,000 years ago indicates that during this period of pronounced aridification they developed cultural innovations that allowed them to significantly enlarge the range of environments they occupied.
A new study shows that difference in water temperature between the Pacific and the Atlantic oceans together with global warming impact the risk of drought and wildfire in southwestern North America.
A coastal zone management plan designed to safeguard Belize's natural assets has produced a win-win opportunity for people and the environment, providing a valuable framework for other coastal nations around the world where overfishing, development, and habitat degradation are increasingly serious problems.
A new study found that Caribbean staghorn corals (Acropora cervicornis) are benefiting from 'coral gardening,' the process of restoring coral populations by planting laboratory-raised coral fragments on reefs.
The US Department of Energy's National Renewable Energy Laboratory (NREL) has confirmed the technical and economic viability of integrating 175 gigawatts (GW) of renewable energy into India's grid by 2022.
With numerous installations of solar power systems for residential homes, there is a challenge to balance supply and demand to make these intermittent energy sources reliable. Demand response is one promising way to increase operational flexibility and energy efficiency, and researchers in Malaysia have incorporated scenarios in case studies based on 100 urban low-voltage network samples to learn more. They report their findings in this week's Journal of Renewable and Sustainable Energy.
