In 2010, global temperatures continued to rise. A new analysis from the Goddard Institute for Space Studies shows that 2010 tied with 2005 as the warmest year on record and was part of the warmest decade on record. (Image credit: NASA/Earth Observatory/Robert Simmon)
Glacial Retreat in Glacier National ParkPredictions suggest all glaciers in Glacier National Park will have melted by 2030.Should the name then be changed to Glaciated National Park?
River flows in Montana depend mostly on snow pack, infiltration of melted snow into soil surfaces, and ground water movement to streams.

Earlier runoff may force construction of more storage reservoirs & heavier reliance on ground water.
Fire even without a warming climate can cause earlier snow melt…Copper Bottom snow water equivalent as compared to other Snotel sites before fire in 2000 vs. Copper Bottom after fire in 2006NRCS figures from Scott Oviatt
Multiple studies show that total discharge increases from relatively small research watersheds are statistically significant when ~20 to 25% of a basal area is removed from forests.

Discharge before and after failure of a beaver dam shows the water table dropped about 8 cm during 14 hours after of the dam failed, water table before dam failure. This water level is suitable for persistent wetlands formation before dam failure.Westbrook et.al. WATER RESOURCES RESEARCH, VOL. 42, 2006
Examples of beaver-influencd channel form. Photos a, c, and e show channel avulsions or splits where an abandoned beaver dam is present.

Example of Riparian RestorationWillow Planting - Pueblo Canyon Santa Fe NF, 2008In this example both channel narrowing and aggradation have occurred. Eventually beaver could establish a population once there is sufficient willow for food and dam construction.
