A massive new study of bumble bees has linked their rapid decline to climate change that is shrinking bee ranges across Europe and North America. Biologist Jeremy Kerr of the University of Ottawa says bees are not migrating north like some other species as the climate warms, and are losing habitat in the south due to the heat. (The study, the first of its magnitude, suggests bumble bees are losing nine kilometres of their southern ranges per year -- and the trend is the same across continents in the northern hemisphere. The study took into account the impact of pesticides such as neonicotinoids, which are known to be harmful to bees, but found the declining bee populations pre-date the use of the insecticide and track closely with changes in climate.)
