US Forest Service: US urban trees store carbon, provide billions in economic value
America’s urban forests store an estimated 708 million tons of carbon, an environmental service with an estimated value of $50 billion, according to a recent U.S. Forest Service study. The annual net carbon uptake by these trees is estimated at 21 million tons and their economic benefit at $1.5 billion.

NASA–Jet Propulsion Laboratory: NASA Opens New Era in Measuring Western U.S. Snowpack
A new NASA airborne mission has created the first maps of the entire snowpack of two major mountain watersheds in California and Colorado, producing the most accurate measurements to date of how much water they hold. The agency plans to exand the mapping to other mountain watersheds.

Lawrence Berkeley National Laboratory: New Study: As Climate Changes, Boreal Forests to Shift North and Relinquish More Carbon Than Expected
Boreal forests will likely shift north at a steady clip this century. Along the way, the vegetation will relinquish more trapped carbon than most current climate models predict.

University of Wisconsin: Decline in snow cover spells trouble for many plants, animals
In a warming world, winter and spring snow cover in the Northern Hemisphere is in decline, putting at risk many plants and animals that depend on the space beneath the snow to survive the blustery chill of winter.

University of Calgary: Human impacts on natural world underestimated
A comprehensive five-year study by University of Calgary ecologists indicates that conservation research may not giving enough consideration to the influence of human activity on natural ecosystems and food chains.
