Description: Over the past decade, native bark beetles (Coleoptera: Curculionidae) have killed billions of trees across millions of hectares of forest from Alaska to Mexico. Although bark beetle infestations are a regular force of natural change in forested ecosystems, several current outbreaks occurring simultaneously across western North America are the largest and most severe in recorded history. Bark beetle ecology is complex and dynamic, and a variety of circumstances must coincide for a large scale bark beetle outbreak. While outbreak dynamics vary from bark beetle species to bark beetle species and from forest type to forest type, a combination of several factors appear to be driving current outbreaks, including a changing climate.

Keywords: Global warming, climate change, latitudinal gradient, climate models, climate normals.
