June 28, 2013--Climate change threatens forest survival on drier, low-elevation sites (Science Daily)

Predicted increases in temperature and drought in the coming century may make it more difficult for conifers such as ponderosa pine to regenerate after major forest fires on dry, low-elevation sites, in some cases leading to conversion of forests to grass or shrub lands, a report suggests.


June 28, 2013--Cattle grazing and clean water are compatible on public lands, study finds (Science Daily)

Cattle grazing and clean water can coexist on national forest lands, according to research by the University of California, Davis. The study, published in the journal PLOS ONE, is the most comprehensive examination of water quality on National Forest public grazing lands to date.

Having access to fresh water is a human necessity. We rely on fresh water not only for drinking, but also for crop irrigation and food production. And in an ever-changing world, with ever-changing landscapes, many communities are often faced with access limitations to fresh water due to both natural and man-made causes.

Smart irrigation is becoming a hot landscaping specialty as groundwater aquifers are increasingly sucked dry.


June 27, 2013--Fires threaten water quality (Pagosa Sun)

Not only are the fires threatening the landscape, they are also threatening water quality in Pagosa Country. With monsoon season approaching, residents can expect to find silt, ash and debris in their water sources. This turbidity can impact the capacity of reservoirs as well as the quality of water. Until the monsoon arrives, conditions are perilously dry.


June 27, 2013--USDA declares 12 Colorado counties disaster areas to drought (Pagosa Sun)

Colorado U.S. Sen. Michael Bennet has announced the U.S. Department of Agriculture (USDA) has designated six Colorado counties as primary natural disaster areas and six more as contiguous disaster areas due to ongoing severe drought conditions. The designations mean that farmers and ranchers in these counties are eligible for additional Farm Service Agency assistance.

What happens when there's no wind and wind turbines stop turning? What provides the back up power for this clean energy source on calm, windless days?


June 26, 2013--‘Extreme’ dust events can speed runoff by 6 weeks (Summit Voice)

Even before a series of intense dust storms coated the Rocky Mountain snowpack in 2009 and 2010, scientists had calculated that the dust speeds the spring meltdown and reduces runoff in the Colorado River Basin by as much as 5 percent, based on data gathered between 2005 and 2008.


June 26, 2013--Study: Colorado River vulnerable to 'megadrought' (Coloradoan)

How will the Colorado River be affected by drought and climate change? It’s more complicated than studies have previously shown, but the bottom line is the river’s flows are likely to greatly decline, according to an American Meteorological Society paper co-authored by Bradley Udall, director of the Western Water Assessment at the University of Colorado Boulder.
