Now it's the Caribou suffering because of global warming. They've experienced a 60% decline in the last 30 years, and the future looks even worse. The reasons:
Earlier spring green-ups now occur before migrating herds arrive north. This deprives mothers and calves of quality feeding.
Warmer summers cause more intense insect activity, harassing animals and affecting their feeding.
The impact of more freezing rain, in place of snow, has negatively impacted lichens that animals feed on during the colder months.
One can only wonder how many extinctions it will take before the denialists wake up to what is becoming increasingly obvious to everyone else.
