Ocean warming affecting fish stocks and crop yields

The warming of the world’s oceans is spreading dangerous diseases and affecting fish stocks and crop yields, a major new report has warned.

Conservationists warned the world is “completely unprepared for” the impacts of warming oceans on wildlife, natural systems and humans, some of which are already being felt.

Even with action to significantly reduce the greenhouse gas emissions which are causing ocean warming, there will still be a high risk of impacts, according to the report launched by the International Union for Conservation of Nature (IUCN).
