Bullshit! Any and all sub freezing temps would have killed off most of the beetle pops. Its the Govt.'s strict regulations against logging that has caused their problem, not global warming and not the f'n beetles.........altho Yoko Ono could kill a tennis shoe.
OBTW - There’s a new bettle on the continent, imported from Russian Siberia by accident. Of course they’re proliferating. This has been going on for decades. The good reporter must not have done a Google search.
Pine beetle infestations are a natural part of nature’s cycle. Pine beetles generally infest trees that are drought stricken or competing too heavily with other trees for water and nutrition. The pine beetle causes the affected trees to weep sap, which in turn dries these weaker trees out. Eventually, a forest fire or heavy storms will reduce the over-population of pines allowing the stronger trees to prosper.
