Heads are being pulled out of the sand, only to be met with more bad news regarding the warming of the Earth.
Scientists now have evidence that changes are occurring in the Gulf Stream, the warm and powerful ocean current that tempers the western European climate. Without the influence of the Gulf Stream and its two northern branches, the North Atlantic Drift and the Canary Current, the weather in Britain could be more like that of Siberia, which shares the same latitude.
Wadhams and other scientists say the slowing of the Gulf Stream could contribute to other severe effects on the planet, such as the complete melting of the Arctic ice cap in the summer months. That could eliminate the habitat and lead to the extinction of Arctic wildlife, including the polar bear. Current predictions indicate that could happen as early as 2020 or as late as 2080.
Look, I don't mean to sound harsh... and this IS just one piece of the evidence puzzle... but if you've been skeptical about global warming, it's time to wake up. The clear scientific data is overwhelming, and the process appears to be moving faster than anyone predicted.
