Dee Boersma

On Wednesday’s CBS "Early Show," co-host Maggie Rodriguez teased an upcoming segment on global warming by fretting: "...are penguins sending us warning signs about global warming?" Later, correspondent Debbye Turner talked to biologist Dee Boersma, who claimed that "Well, penguins are the canaries in the coal mine. Penguins are telling us, as marine sentinels, that our southern oceans are changing."

Boersma, who according to newsmeat.com donated $1,000 to John Kerry’s 2004 presidential campaign, went on to condemn a wide range of human activity that she felt was harming global penguin populations: "Penguins are affected not only by climate variation and climate change, but they're affected by lots of activities that we do from moving oil around, because we spill oil, from plastics that we dump into the oceans, to fishing that takes away their food."

Earlier in the segment, Turner lamented: "We've all seen pictures like these. Polar bears in danger because global warming is literally melting their habitat. But they are far from the only animal affected by climate change." She later discussed the dire situation facing penguins: "Academy award winning documentary March of the Penguins chronicled the Emperor Penguins amazing struggle to reproduce and survive. Experts say because of soaring temperatures and decreasing ice that the day could come that they make their final march."
