Humans use water for everything from drinking and bathing to growing crops, supporting livestock and fish farms, shipping goods, generating electricity, and simply relaxing and having fun. Yet climate change is producing profound changes in this precious commodity, threatening water availability, access, and even quality ... read more >>
Science has struggled to explain fully why an ice age occurs every 100,000 years. As researchers now demonstrate based on a computer simulation, not only do variations in insolation play a key role, but also the mutual influence of glaciated continents and climate.
Ice ages and warm periods have alternated fairly regularly in Earth's history: Earth's climate cools roughly every 100,000 years, wi ... read more >>
In Clermont, FL, as glass broke, the ground shook and lights went out, vacationers evacuated a central Florida resort building before a sinkhole caused a section of the villa to partially collapse early Monday. ... read more >>
As abnormal dryness continues to expand eastward, according to the latest U.S. Drought Monitor, forecasts are not showing any indication of above or below normal precipitation through October, the state climatologist at the University of Nebraska-Lincoln said.
There is no signal of improving conditions, but there is nothing there that signals conditions will get worse either, said Al Dutcher, st ... read more >>
Parched Jordan on Wednesday officially inaugurated a near-billion-dollar project to supply the capital with water from an ancient southern aquifer to help meet a chronic shortage.
King Abdullah II pushed the start button to begin pumping water from the 300,000-year-old Disi aquifer, 325 kilometres (200 miles) south of Amman.
"The Disi project will provide the capital and other governorates with ... read more >>
Dimock families and advocacy groups called today on EPA Administrator Lisa Jackson to compel the state of Pennsylvania to provide replacement water to the residents after the Environmental Protection Agency’s own preliminary water test results show their water was contaminated from nearby gas drilling. Controversy has surfaced over EPA Region 3’s initial pronouncements that the water poses no imm ... read more >>
Climate Record From Bottom of Russian Lake Shows Arctic Was Warmer Millions of Years Ago - US National Science Foundation (NSF)
The Arctic was very warm during a period roughly 3.5 to 2 million years ago--a time when research suggests that the level of carbon dioxide in the atmosphere was roughly comparable to today's--leading to the conclusion that relatively small fluctuations in carbon dioxide levels can have a major influence on Arctic climate, according to a new analysis of the longest terrestrial sediment core ever ... read more >>
Global water resources modeling with an integrated model of the social–economic–environmental system
Awareness of increasing water scarcity has driven efforts to model global water resources for improved insight into water resources infrastructure and management strategies. Most water resources models focus explicitly on water systems and represent socio-economic and environmental change as external drivers. In contrast, the system dynamics-based integrated assessment model employed here, ANEMI, ... read more >>
Three Global Climate Models (GCMs) output (precipitation and temperature), bias corrected with the WATCH Forcing Data (WFD), for the A2 and B1 scenarios, are used for drought assessment at a basin scale. The HBV model produced results for flow, soil moisture and groundwater reservoir and shows that decreasing hydrological parameters will result to increasing drought duration. Future scenarios e ... read more >>
