Abstract

According to the Intergovernmental Panel on Climate Change, extreme weather events are expected to increase in intensity, duration, and frequency with global warming. Intense cold spells as low as -40 to -45°C have swept through Quebec over the past decade. However, more recent winters have generally been milder, especially in 2018, when a long period of thaw was followed by freezing cold in mid-March. These leaps in temperature were an opportunity for Canadian Forest Service researchers to assess the impact of such phenomena on the winter survival of young spruce budworm larvae.
