Marine governance in New Zealand is fragmented, with several agencies operating under various statutes. But a more collaborative, ecosystem-based approach to better protect the ocean is emerging.
Climate change is making oceans more acidic globally. Now, scientists are finding that large storms can send pulses of acidic water into bays and estuaries, further stressing fish and shellfish.
The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.
The report synthesises the latest science about Australia’s climate – and paints a worrying picture.
There is only a single mooring managed by French researchers that monitors the impacts of climate change on West African Canary Current.
From planting mangroves to dumping minerals in the ocean, there are lots of ideas for ocean carbon dioxide removal – and even more questions.
Humans have failed to take good care of the ocean — and the environment at large — because we undervalue its goods and services.
Tiny seashells draw carbon to the ocean floor when they die. This is the most significant geological process of carbon storage today, and it might increase in a warmer world, as it did in the past.
For the opening of the One Ocean Summit in Brest from February 9 to 11, 2022, France’s marine research institute looks at promising avenues of research to protect the planet’s largest ecosystem.
Sponges are ancient marine animals and have already shown robustness against stresses from climate change. New research now shows they can also tolerate low-oxygen conditions.
The old ways of keeping giant clam species healthy won’t work with climate change. We need new techniques - and fast.
The ocean has been buffering us from the impacts of climate change, but it is reaching the limit of this capacity. Integrating ocean and climate policy will be crucial.
Carbon dioxide can be classed as pollution under the UN law of the sea and countries have an obligation to prevent it from entering the ocean.
Cold-water corals live in the Atlantic’s frigid depths – and the UK is a stronghold for them.
Pacific island nations have shaped the international response to climate change. At the United Nations summit in Glasgow, they’ll draw a line in the sand.
The latest IPCC report makes it clear we can no longer stop the seas from rising, but we can still control how much and how fast sea levels change.
Solar geoengineering could theoretically cool the Earth to slow global warming, and it has been controversial. Still, countries should research its risks and benefits.
Sharks grow slowly and produce few young compared to bony fishes. In many cases, this means that their populations are fished out faster than can be replenished if not well managed.
A study of 183 coral reefs worldwide quantified the impacts of ocean warming and acidification on reef growth rates. Even under the lowest emissions scenarios, the future of reefs is not bright.
A future of heat and strife or humanity’s finest hour – our response to climate change today will define the 21st century.
