An Unexpected Victim of Climate Change: Moose

Polar bears serve as the poster children for climate change. But global warming also threatens many other species that don't get as much news coverage.

Moose in the Rocky Mountains become the latest climate change catastrophe icon recently, as their populations have plummeted with warming temperatures. But it's not just heat stress that is killing them off. Biologists are finding brain worms, liver flukes and ticks, as many as 150,000 on a single moose, are infecting the population to death.

Increased temperatures are allowing northern forest ticks to survive over the winter, when the blood-suckers and their eggs would normally die. This leaves an infected moose with no respite as the ticks breed again in the spring. The moose will continue to scratch and rub off its fur, develop anemia, and eventually die of emaciation.
