Tree rings record changing snowpack, research finds

Greg Pederson sees the recent publication of his research on snowpack declines in the West as a prime opportunity to reiterate the difference between climate and weather in this record-setting wet spring.
Pederson, an ecologist with the U.S. Geological Survey in Bozeman, was the lead author of a paper published last week in Science magazine detailing the decline in snowpack observed by examining tree rings from the watersheds of the Columbia, Missouri ... Full Story »

...an interesting article based on a scientific report examining tree rings in the Western states which reflect the decline in snowpack over an extensive period of time. The publication links the declining snowpack to dramatic changes in the weather patterns in recent years without actually speculating on human factors that may have influenced the change.

...the apparent overlap given between the dates of the "Medieval Warm Period"(950-1250) and the Little Ice Age(1150-1850) given in the article can probably be explained by fluctuating mini warming and cooling trends within those time spans. The weather channel carried an interesting documentary on the subject, giving greater detail of the effects on agriculture and human living conditions in Europe.
