ScienceDaily (Feb. 28, 2011) — Lodgepole pine, a hardy tree species that can thrive in cold temperatures and plays a key role in many western ecosystems, is already shrinking in range as a result of climate change -- and may almost disappear from most of the Pacific Northwest by 2080, a new study concludes.

The pine bark beetle may not leave much for climate change to work on.

I think the article is suggesting that the reason for the Pine Bark Beetles is because of warmer temperatures.

"Now their populations and pheromone levels are getting so high they can more easily reach epidemic levels and kill almost all adult trees," he said. "Less frost, combined with less snow favors heavier levels of bark beetle infestation. We're already seeing more insect attack, and we project that it will get worse.
