It has long been known that sea otters, nursed back from brink of extinction in the past several decades, provide huge benefits for the vitality of undersea kelp forests. But a pair of UCSC scientists recently found that those benefits extend into the atmosphere, finding a strong connection between otters, kelp and global warming. The new research has found that if otters covered the globe, the resulting growth in kelp forests would strip 10 percent of the carbon dioxide from the atmosphere. [Source: San Jose Mercury News]
