Joe Littman GLG 141 B 3T/TH The title of this article is “Long-Duration Drought Variability and Impacts on Ecosystem Services: A Case Study from Glacier National Park, Montana.” This journal relates precipitation to many changing factors in Glacier National Park: Changes in the climate, “ Timing of snowmelt, Summer streamflow, Timing and quantity of snowmelt alters stream temperature, Reduction in winter recreational opportunities, Loss of sense of place associated with glaciers, Loss of cultural and religious icon, Changes in snow alters whitebark pine demography and productivity with consequences for grizzly bear habitat, Fire extent, frequency, and severity, Pathogen outbreaks, Recreation sites and roads close due to fire and fire risk, Drought increases access.” This study can help predict how the climate may change based on recent precipitation statistics. The conclusions of this article also relate the size and melting of glaciers to the mount of precipitation. I am not a supporter of global warming and these

Unformatted text preview: factors may be the driving force behind the reduction of glacial mass in last 30 years. Interesting Quote: “Persistent shifts in moisture regimes related to decadal and multidecadal climate variability are a major driver of landscape changes in Glacier NP. Interactions between snowpack and summer drought over decadal to multidecadal time scales appear to have a particularly strong impact on fire regimes in the Glacier NP region. On annual and interannual time scales, fire within Glacier NP is undoubtedly driven by summer drought and possibly snowpack conditions.” If I were asked to share what I learned with others I would explain to them the connections between precipitation amounts and the climate of Glacier National Park. It would also be important to explain to them that these changes in climate don’t happen based short term precipitation changes, but happen based on long-term changes in precipitation, usually over one or more decades of a trend in precipitation....
