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.” [42] 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. [29] The oceans absorb more than 90% of the heat generated by human-caused global warming. [41] Since 1970, the upper ocean (above 700 meters) has been warming 24-55% faster than previous studies had predicted. [41]

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. [166] Warming oceans also contribute to sea level rise due to thermal expansion, and can add to the intensity of storm systems. [167]
