Climate Change is a change in the mean or variability of one or more measures of climate, for example temperature or precipitation, that persists for an extended period, typically decades or longer. Although climate variations are well documented in the Earth’s history the current warming trend differs from earlier shifts. Earth’s climate has been rapidly changing during the 20th century and the rate of change has been faster since the 1950s

In the Pacific Northwest, increased greenhouse gases and warmer temperatures have resulted in a number of physical and chemical impacts. All of these changes will cause major perturbations to ecosystem conditions, possibly imperiling species that evolved in response to local conditions.
