In the ocean, phytoplankton helped by diazotrophs play an outstanding role in withdrawing CO₂ from the atmosphere. But climate change is disturbing this delicate balance.
The Pacific Ocean produces oxygen, helps regulates the weather, provides food and livelihoods. It's a place of fun, solace and spiritual connection. But its delicate ecology is under threat.

What if the nightly news had regular updates on forest clearing, ocean temperatures and fossil fuel consumption? These indicators sit alongside temperatures as signs of climate change.
The IPCC report provides fresh details on scope of the effects of climate change.

A new Intergovernmental Panel on Climate Change report makes clear human-induced climate change threatens the health and function of the ocean and cryosphere - the frozen regions of the Earth.
Resilient corals are offering hope for bleached reefs.

Acidic oceans are disrupting a major part of the carbon cycle, slowing how seas absorb carbon from the atmosphere. This could massively speed up the effects of climate change.v

In a study that cultivated coral 'gardens' with varying numbers of species, plots with more species were healthier. This finding could inform strategies to help coral reefs survive climate change.
Australia is facing an increase in extreme heat, fire danger weather, floods and marine heatwaves, according to the latest biennial snapshot from the Bureau of Meteorology and CSIRO.

Marine sponges are ancient organisms that have survived mass extinctions. Many are more tolerant of climate change and may dominate over corals in future reef systems.
Researchers studied reef sands at Heron Island, Hawaii, Bermuda and Tetiaroa. In this photo, white areas show the predominance of sand on reefs.

Ocean acidification poses an increasing threat to the sediments that form the framework of coral reefs - within around 30 years, these carbonate sands may no longer be able to form.

The federal government's new funding aims to spread the net wide in investigating possible ways to protect the Great Barrier Reef's corals. Winning this battle will require a wide range of weapons.
A tank can give a good idea of what will happen out in the wild.
A new study suggests the benefits of a boost to marine plant growth from increased carbon dioxide will be cancelled out by the increased stress to fish species.
The oceans are filled with sounds produced by animals. However, a recent study shows that ocean sounds are diminishing due to nutrient pollution and ocean acidification.
