Forests in the Pacific Northwest are dying twice as fast as they were 17 years ago, and scientists blame warming temperatures for the trend, according to a new study.
The study, to be released Friday in the journal Science, is the first large-scale analysis of environmental changes as contributing factors in the mortality of coniferous forests.
The data for this research was gathered by generations of scientists over a 50-year period at multiple sites in Oregon, Washington, California, Arizona, Colorado, New Mexico and southwestern British Columbia. Seventy-six forest plots, all more than 200 years old, were monitored by scientists doing some of the most rudimentary research -- counting trees.
