These whales have been falsely accused of breathing out enough carbon dioxide to contribute to the greenhouse gas build-up causing climate change, says Trish J.

"The first analysis of whales' effect on greenhouse gases determined that warm-blooded residents -- with whales as the dominant force -- might be respiring 25 percent of the carbon fixed in the Southern Ocean, she says. Later estimates have revised their share downward, and the most recent calculation puts their contribution at 0.3 percent. "

25% revised down to 0.3%? How can this science be credible with such divergent calculation results?
