Climate Change

  • The ocean has taken up more than 90% of the excess heat in the climate system. The rate of ocean warming has more than doubled since 1993. (IPCC)
  • Carbon emissions from human activities are causing ocean warming, acidification and oxygen loss. (IPCC)
  • By 2100, the ocean is very likely to warm by 2 to 4 times with low emissions (RCP 2.6) and 5 to 7 times with high emissions (RCP 8.5) compared to observed changes since 1970. (IPCC)
  • Ocean acidity has increased about 26% since pre-industrial times. At this rate, an increase of 100 to 150% is predicted by the end of the century, with serious consequences for marine life. (UN)
