U.S. - Global Warming Increases Ocean Temperature... A Snowy White Egret in flight above the Morro Bay Estuary,in California. Scientists say a dramatic rise in the ocean temperature led to unprecedented deaths of birds and fish this summer all along the coast from central California to British Columbia in Canada. The population of seabirds, such as Brant Geese, Cormorants, Auklets and Murres, and fish, including salmon and rockfish, fell to record lows. This ecological meltdown mirrors a similar development taking place thousands of miles away in the North Sea. Also caused by warming of the water, the increase in temperatures there has driven the plankton that form the base of the marine food chain hundreds of miles north, triggering a collapse in the number of sand eels on which many birds and large fish feed and causing a rapid decline in puffins, razorbills, kittiwakes and other birds.
