7. Ocean warming has dramatic impact
The coming century will likely bring dangerous and dramatic changes to the planet's oceans, with ever strengthening storms, annual bleaching of almost all coral reefs, loss of biodiversity and severe impacts on fisheries and aquaculture unless humans slash greenhouse gas emissions.
These are the findings of a comprehensive review of the effects of warming oceans, issued by IUCN and compiled by more than 80 scientists from 12 countries. The report chronicles how the seas have absorbed the vast majority of the excess heat trapped in the atmosphere by carbon emissions in recent decades, and how that energy is already altering the planet's weather systems and ecology.
All of these ecological changes have profound impacts on people. Both fisheries and aquaculture would be "severely affected" if humans fail to substantially reduce greenhouse gas emissions, the report said. The impacts will not be uniform, with nations in the tropics and subtropics suffering the worst effects.
