This new report argues that rising temperatures have impacted the world's oceans to a far greater extent than previously acknowledged. Addressing topics such as sea-level rise, ocean circulation, coral reefs, sea birds and invertebrates, as well as the increasing threats to Salmon, the report predicts a dangerous chain reaction in marine ecosystems if global warming continues unabated. On the positive side, it also argues that decisive actions now to reduce pollution can slow the warming and preserve the world's oceans.
