Manmade ocean acidification will have profound impacts on marine life, even without a further increase of CO₂ emissions. Latest evidence shows that sea water chemistry is already changing and only rapid and huge reductions of fossil fuel use and deforestation can help restore ocean’s health, according to IUCN. A new guide, Ocean Acidification: Questions Answered, states that ocean acidification is now happening ten times faster than that which preceded the extinction 55 million years ago of many marine species. If the current rate of acidification continues, fragile ecosystems such as coral reefs, hosting a wealth of marine life, will be seriously damaged by 2050. The guide provides the latest science on the speed and scale of impact that CO₂ emissions will have on the ocean and on humanity. Learn More
