Animals Going Awry As Earth Warms, Scientists Say

Publication: National Geographic News   Date: August 12, 2005   View Article

The world on average is about 1ºF (0.6ºC) warmer today than it was a century ago. That may not sound like a lot, but it’s enough to concern some scientists.

The temperature rise has put feathered, furry, and scaly animals alike in a state of flux. Some are seeking higher ground, others are breeding earlier, and many can’t find enough to eat.

Scientists expect the current bout of global warming to cause animals—as during past climate changes—to shift their habitat ranges and to alter the timing of events like breeding and hibernation.

But these changes—like the warming itself—are already happening more quickly than most researchers expected.
