A recent email I sent to a group of hydrogeologists and fellow travelers reiterated my desire to establish an online community for groundwater and IWRM. I am still working towards that and am searching for a suitable platform. Over 100 people have indicated they would like to be included.
The email elicited a number of responses and a few relevant publications. Here I have posted five publicat ... read more >>
A new paper in the journal Nature Climate Change assesses which human factors are the most important drivers of greenhouse gas emissions.
The authors note know that for every 1 percent increase in human population, greenhouse gas emissions go up by slightly more than 1 percent. But which aspects of human life contribute most—more people, more consumption, or both—and how might that play out in ... read more >>
Hard lessons from around the American West and Australia could help improve groundwater management and protect ecosystems in California, Stanford researchers find. ... read more >>
There is little doubt that natural gas, which is plentiful and cleaner than coal, could help with the country’s energy and climate problems. But as Interior Secretary Ken Salazar once warned, the drilling technique known as hydraulic fracturing could be natural gas’s Achilles’ heel unless the public can be sure it will not pollute water supplies or the air.
Hydraulic fracturing, combined with de ... read more >>
The nation's food supply may be vulnerable to rapid groundwater depletion from irrigated agriculture, according to a new study by researchers at The University of Texas at Austin and elsewhere. ... read more >>
The nation's food supply may be vulnerable to rapid groundwater depletion from irrigated agriculture, according to a new study by researchers at The University of Texas at Austin and elsewhere. The study, which appears in the journal Proceedings of the National Academy of Sciences, paints the highest resolution picture yet of how groundwater depletion varies across space and time in California's ... read more >>
Effect of groundwater use: Using water from wells leads to sea level rise, cancels out effect of dams
As people pump groundwater for irrigation, drinking water, and industrial uses, the water doesn't just seep back into the ground -- it also evaporates into the atmosphere, or runs off into rivers and canals, eventually emptying into the world's oceans. This water adds up, and a new study calculates that by 2050, groundwater pumping will cause a global sea level rise of about 0.8 millimeters per y ... read more >>
The UN Social Commission for Asia and the Pacific Statistical Yearbook for 2011 states that changing weather patterns across the world have increased the occurrence and intensity of the earth’s natural hazards such as torrential rain, floods, droughts and cyclones; which affect countries such as Australia, China, Myanmar and, most importantly, Pakistan. ... read more >>
Wahr’s study clearly notes that lower-altitude glaciers and ice caps are melting, to the tune of about 150 billion tons of ice annually, which the study predicts could lead to an overall rise in sea levels.
Glaciers grow and shrink based on how much snow falls and the temperatures in the area, LiveScience said. Why the Karakoram range isn't melting is still a mystery.
(If you have $18 to rea ... read more >>
Researchers at the University of Pittsburgh have joined an international group of scientists to study past climate changes in the Arctic. Comprising geologists from Pitt's Department of Geology and Planetary Science, the team has analyzed sedimentary and geochemical records of water-level changes in Rantin Lake, located in the boreal forest of Canada's southeastern Yukon Territory. The results we ... read more >>
