Ocean scientists and NGOs call time on government neglect of earth’s life support system | Interamerican Association for Environmental Defense (AIDA) Skip to content Skip to navigation

The Intergovernmental Panel on Climate Change (IPCC) Special Report on the Ocean and Crysophere in a Changing Climate reveals the extent of the crisis facing humanity as the ocean and its services begin to show signs of collapse.

Although the ocean is inextricably linked with the climate, the two working together to make planet Earth habitable, this is the first time that the IPCC has turned its attention to the marine realm.  The resulting report conveys what marine scientists and NGOs have been saying for years, that the ocean is beginning to crumble under an onslaught of needless stressors from overfishing to pollution, compounded by climate breakdown.

The effect of climate breakdown is the most serious, creating acidification, heating and deoxygenation. These three factors have been present in every mass extinction event in Earth’s history; all three are active in the ocean now.

Professor Dan Laffoley of the IUCN World Commission on Protected Areas: “We are an ocean world, run and regulated by a single ocean and we are pushing that life support system to its very limits through heating, deoxygenation and acidification. We are well past 'wake up calls' - what we need now is enlightened self-interest to deliver the actions that protect the ocean and climate and which in turn protect and support humanity.”

The timescales at work within the ocean mean that changes already put into its system – such as warming – will remain at work for hundreds of years, consequently, even with immediate action to curb temperature rise and cut CO2 emissions, ocean services to the planet could still be at risk.

This is why it is so important that all extraneous stressors on the ocean which can be controlled, are.  Overfishing, pollution, destruction of habitats, ecosystems and biodiversity are all stressors which can be stopped to support the resilience of the ocean to withstand the climate crisis.

Gladys Martínez, senior attorney of the Interamerican Association for Environmental Defense (AIDA): “The IPCC report makes it crystal clear that time is running out for ocean action. We have a small window of opportunity to achieve a strong High Seas Treaty by 2020 and to protect at least 30% of the ocean by 2030, two measures that will help defend the resilience of the ocean. The treaty is being negotiated before the United Nations and states must complete it by 2020, in line with the UN General Assembly resolution and demonstrating high ambitions.”

Although the picture painted by the IPCC is undeniably bleak, there are measures which can be taken now to help bolster the resilience of the ocean and which governments need to finally and robustly take action on.

State parties to the legally binding Convention on Biological Diversity will negotiate new targets to protect biodiversity at a meeting in 2020. The target for marine biodiversity should be to protect at least 30% of the ocean through implemented highly and fully protected areas, with the remaining 70% of the ocean sustainably managed.

Bringing an end to overfishing and pollution in all its forms and preventing further biodiversity, ecosystem and habitat loss are essential measures within our reach.

Tackling climate breakdown and holding warming at or as close to 1.5 degrees Celsius as possible is essential if the ecosystem services of the ocean are to survive. All states need to commit to new and more ambitious plans (NDCs) in 2020 to achieve this.
