How Are Wildlife Populations Affected by Climate Change?
Find out which animals are most at risk by even small changes in temperature. “Most researchers agree that even small changes in temperature are enough to send hundreds if not thousands of already struggling species into extinction unless we can stem the tide of global warming. And time may be of the essence: A 2003 study published in the journal Nature concluded that 80 percent of some 1,500 wildlife species sampled are already showing signs of stress from climate change. The key impact of global warming on wildlife is habitat displacement, whereby ecosystems that animals have spent millions of years adapting to shift quickly. Ice giving way to water in polar bear habitat is just one example of this. Another, according to The Washington Post, is the possibility that warmer spring temperatures could dry up critical breeding habitat for waterfowl in the prairie pothole region, a stretch of land between northern Iowa and central Alberta. Affected wildlife populations can sometimes move i
