Top Pro & Con Arguments
Ocean temperatures are rising at an unprecedented rate due to anthropogenic global warming.
Peter Gleckler, PhD, a climate scientist at Lawrence Livermore National Laboratory, said, “The bottom line is that… most of the observed global ocean warming over the past 50 years is attributable to human activities.”  The IPCC stated in a report that due to human-caused global warming, it is “virtually certain” (99-100% probability) that the upper ocean warmed between 1971 and 2010.  The oceans absorb more than 90% of the heat generated by human-caused global warming.  Since 1970, the upper ocean (above 700 meters) has been warming 24-55% faster than previous studies had predicted. 
Warmer ocean waters can harm coral reefs and impact many species including krill, which are vital to the marine food chain and which reproduce significantly less in warmer water.  Warming oceans also contribute to sea level rise due to thermal expansion, and can add to the intensity of storm systems. Read More
