Coral reefs share genetic material across wide areas, with help from ocean currents. This ability is especially important during episodes like the mass bleaching currently occurring.

Hardening electric transmission systems and monitoring ocean temperatures are two key priorities.
Baby corals may hold promise for building coral reef resilience in Seychelles and beyond.
New research shows climate change can drive sudden ocean cooling too. This can have devastating effects on marine life such as bull sharks and manta rays.
Coastal fishing communities in west Africa face increased poverty as fish stocks decline.
Just as the world’s zoos breed critically endangered animals in captivity to repopulate the wild, scientists are building a global effort to freeze corals for reef restoration.
The best strategy to protecting Earth’s coral reefs is to dramatically cut greenhouse gas emissions. But in the meantime, we must urgently make corals more resilient.
Even a small rise in sea level can have big impacts on coastal properties, so we must do all we can to limit the changes while taking them into account in coastal land-use planning.
Severe bleaching is forecast to hit 12 Indonesian marine protected areas every year by 2030 – then spread to other areas. Here’s what locals, experts and the government say we need to do to save them.
Muttonbird ‘wrecks’ are becoming more common. Despite speculation about many possible causes, the evidence points to changes in the Arctic ocean ecosystem from where the birds migrate to Australia.
The same instruments used to measure earthquakes pick up vibrations as ocean waves put pressure on the sea floor. Four decades of data tell a story about ocean storms.
Australian is experimenting with marine cloud brightening to cool and shade the Great Barrier Reef. Here’s how it works.
New Zealand’s kelp forests provide food and shelter for many marine species of commercial and cultural value. But they are at risk from warming oceans, run-off from land and marine invaders.
This may buy us time, but many reefs are still doomed without serious action on climate change.
New Zealand’s marine policies are scattered across multiple laws and regulatory institutions. A dedicated ministry would overcome this fragmentation and help protect vital ecosystems and resources.
Climate change is relentless and largely predictable, but it is influenced by natural variability. This means the largest temperature rise usually comes at the end of an El Niño event.
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.
Scientists have detected a 30% slowdown of the deep ocean currents that form in Antarctica, with profound consequences for Earth’s climate, sea level and marine life.
There’s a 98% chance of a record hot year by 2028, and a 66% chance of exceeding the 1.5°C threshold for at least that year, according to the latest World Meteorological Organization update.
The world’s oceans regulate our climate, but they are entering uncharted territory, with record surface warming and changes to Antarctica’s deep meltwater which drives global currents.
