IUCN: Honolulu, Hawaii, 5 September (IUCN) – Ocean warming is affecting humans in direct ways and the impacts are already being felt, including effects on fish stocks and crop yields, more extreme weather events and increased risk from water-borne diseases, according to what has been called the most comprehensive review available on the issue, launched today by the International Union for Conservation of Nature (IUCN) at the IUCN World Conservation Congress in Hawaii.
The report, Explaining ocean warming: Causes, scale, effects and consequences, reviews the effects of ocean warming on species, ecosystems and on the benefits oceans provide to humans. Compiled by 80 scientists from 12 countries, it highlights detectable scientific evidence of impacts on marine life, from microorganisms to mammals, which are likely to increase significantly even under a low emissions scenario.
“Ocean warming is one of this generation’s greatest hidden challenges – and one for which we are completely unprepared,” says IUCN Director General Inger Andersen. “The only way to preserve the rich diversity of marine life, and to safeguard the protection and resources the ocean provides us with, is to cut greenhouse gas emissions rapidly and substantially.” Ocean warming is already affecting ecosystems from polar to tropical regions, driving entire groups of species such as plankton, jellyfish, turtles and seabirds up to 10 degrees of latitude towards the poles, causing the loss of breeding grounds for turtles and seabirds, and affecting the breeding success of marine mammals, according to the report.
National Oceanography Centre scientists have contributed to the publication of an authoritative new report on the impacts of ocean warming on species, ecosystems, and ocean ‘goods and services,’ such as carbon management, fisheries and coastal protection.
