They're nature's ultimate tough guys; amphibians -- like frogs and salamanders -- have survived for millions of years and even through multiple mass extinctions. But scientists at University of California, Berkeley, and San Francisco State University, say they're seeing frogs die off at an alarming rate, which they believe is sending a clear message about the severity of our climate change and global warming. In other words, in their estimation, because amphibians have endured so much in the past, what's happening now with their declining populations is like the canary in the environmental coal mine.
