Their eggs are kill ed by extreme cold events, which no longer occur Rising temperatures have also stressed the trees, making them more vulnerable to mountain pine beetle mortality. The mortality trees is now so extensive that the forests are projected to become a net carbon source instead of a carbon sink, releasing 200 megatons of carbon per year by the year 2020. The response of mountain pine beetles to warmer temperatures can be described as: () acclimation adaptation O radiative forcing range shift phenological shift
