Would you believe it if I told you that tropical fish are now swimming in temperate waters? Fish are coming up from the Caribbean. They have been seen as far north as Massachusetts. The oceans have been warming since 1975 and the experts now agree this is caused by human induced global warming. Here is an excerpt from Wake Up Call: Oceans Warming Up Showing why this phenomena is occurring:
For one, ocean surface temperatures worldwide have risen on average 0.9 degrees Fahrenheit, or 0.5 degrees Celsius, and ocean waters in many tropical regions have risen by almost 2 degrees F (1 degree C) over the past century. This is 30 times the amount of heat that has been added to the atmosphere, a significant amount even though the ocean has a lot more mass than the atmosphere. Also, the incidence of coral bleaching has increased worldwide since 1979, and scientists now generally link these mass bleachings to global warming. The largest bout of coral bleaching ever (1997-1998) occurred during the warmest 12-month period on record and in nearly every region of the world. It was a wake-up call that global warming was not just a distant threat. Scientists have known for a long time that the ocean plays a huge role in climate. Covering 70% of the globe, it stores 1,000 times more heat than the atmosphere. But often overlooked in the public debate on climate change is the ocean’s synergistic role — how the ocean responds to the growing amount of heat-trapping gases in the atmosphere.
