We looked at some of the atmospheric consequences for using natural gas last week, and this week we’re taking a closer look at water. Water lost to fracking may be mitigated by water savings during power generation.

April 4th, 2014Tsegay Wolde-Georgis, of the INSTAAR program Consortium for Capacity Building (CCB), is leading a project to introduce the cultivation of apple trees irrigated by water-filled, buried clay pots to the mountainous, dry region of Atebes, a village of 4000 people in northern Ethiopia. Over the last 30 years, land degradation and climate change have exacerbated existing constraints of drought, soil erosion, deforestation, poor food supply consisting entirely of cereal grains, and lack of access to water. The goal of the clay pot project is to improve the resiliency of the community to climate-related hazards through demonstration and capacity building. So far, the project has led not only to the cultivation of high-value fruits and vegetables, but to erosion control and improved water supplies.
December 5th, 2013INSTAAR faculty and graduate students will share their research at the American Geophysical Union (AGU) Fall Meeting (http://fallmeeting.agu.org/2013/) held in San Francisco, 9 to 13 December.

October 3rd, 2012The NSF has awarded a $12 million grant to a CU-Boulder-led team, including the leaders of the CWERC research center, to explore ways to maximize the benefits of natural gas development while minimizing negative impacts on ecosystems and communities. The team will examine social, ecological and economic aspects of the development of natural gas resources, including fracking, and the protection of air and water resources. The project will focus on the Rocky Mountain region, where natural gas development, as well as objections to it, are increasing.
September 10th, 2012A new University of Colorado Boulder-led study that ties forest “greenness” in the western United States to fluctuating year-to-year snowpack indicates mid-elevation mountain ecosystems are most sensitive to rising temperatures and changes in precipitation and snowmelt. Led by CU-Boulder researcher Ernesto Trujillo and Assistant Professor Noah Molotch, the study team identified the threshold where mid-level forests sustained primarily by moisture change to higher-elevation forests sustained primarily by sunlight and temperature. Being able to identify this “tipping point” is important because it is in the mid-level forests--at altitudes from roughly 6,500 to 8,000 feet--where many people live and play in the West and which are associated with increasing wildfires, beetle outbreaks and increased tree mortality.
September 7th, 2012Warmer air temperatures since the 1980s may explain significant increases in zinc and other metal concentrations of ecological concern in a Rocky Mountain watershed, reports a new study led by CU-Boulder and the USGS. Rising concentrations of zinc and other metals in the upper Snake River just west of the Continental Divide near Keystone, Colo., may be the result of falling water tables, melting permafrost and accelerating mineral weathering rates, all driven by warmer air temperatures in the watershed. Researchers observed a fourfold increase in dissolved zinc over the last 30 years during the month of September.
July 31st, 2012In conjunction with the “Discover Earth: A Century of Change” exhibit, Jim White and Mark Williams will lead climate science-focused presentations at the Rifle Branch Library, 207 East Avenue, on Thursday, Aug. 9 and Thursday, Aug. 16.

December 20th, 2010James Syvitski was elected a Fellow of the American Geophysical Union (AGU) for "bringing new insights to the disciplines of oceanography, river and fjord processes, and sediment transport". Fellowship is bestowed on less than 0.1% of the total AGU membership of about 58,000 in any given year and recognizes scientists who have attained acknowledged eminence in the Earth and space sciences.
December 10th, 2010Caitlin Crouch and Diane McKnight found that rising concentrations of zinc in the Snake River watershed on Colorado's Western Slope may be the result of earlier spring snowmelt. They observed a four-fold increase in dissolved zinc over the last 30 years during September and October, the lowest water flow months. They also noticed that the low flows have become lower - and probably the soil along the stream drier - as air temperatures have risen and snowmelt has begun two to three weeks earlier.

September 17th, 2003The ability of several of Colorado's prime ski areas to respond to winter drought is threatened by acidic runoff from abandoned mines, according to researchers at the University of Colorado at Boulder and the Northwest Colorado Council of Governments. Contamination known as acid-rock drainage enters waterways, such as Summit County's Snake River, that are used for making artificial snow. When the snow melts, the water can run into streams not previously polluted, further spreading the contamination, said the research team.

January 11th, 2019Glacial lake outburst floods (GLOFs) are sudden, fast flowing releases of glacial lake water that move downslope as a result of ice- or moraine-dam failures. As water rushes downslope, it picks up rock, mud, and debris, endangering people, infrastructure, fields and livestock in its path. Recent research, published in Landslides, provides new understanding of GLOFs by studying their trigger mechanisms and disaster impacts.
