So what if we told you that according to many of the world's leading scientists, such changes have already begun -- not over an instant, but due to global warming, the next 100 years, and that we stand on the brink of a mass extinction. ABC7's Wayne Freedman: "It's the equivalent of?" Dr. Terry Root, Stanford biologist: "The extinction that was felt when the dinosaurs went extinct."
Dr. Terry Root, a biologist at Stanford University is home today from an international meeting of climate specialists who have reached a consensus, that from studying endangered species, they can link humans, fossil fuels and global warming. Dr. Terry Root: "We are going to have an increase in temperature by about two degrees. We really can't stop that."
The big deal about global warning is that wildlife is coordinated. In Southern California, for instance, the Checkspot butterfly relies on nectar from a wildflower that used to bloom at just the right time for the butterfly to spread its pollen. But if one reacts to temperature, and the other to sunlight, they fall out of sync and both disappear. Dr. Terry Root: "Right now, today, we have species A relying on species B, and species B relying on species C, species C relying on species D. Now if something happens to species D, (then) C, B and A all are in turmoil."
But unless we know where to look, this mass extinction, they say, remains subtle, affecting many little-known creatures in far away places. But in another context, they describe it as watching the wave of a deadly tsunami while still offshore. A rise of one degree in the last century may not sound like much, unless it accelerates into the next one.
