Atmospheric, marine, environmental, biological and medical scientists join in calling for more focus on the damage being wrought by climate change.

Tiny organisms change ocean acidity to benefit themselves.

'Smell-free seas' would be a disaster for marine life.
Nice to see you: parrotfishes prey on seaweed, which consume seaweeds that can outcompete, smother or even poison corals.
A combination of factors – pollution, disease and overfishing – is harming corals but scientists have found clues to effective treatment by studying corals' microbiome.
South Africa’s oceans offer numerous economic opportunities, if ocean acidification is dealt with properly.
South Africa has the opportunity to benefit from its ocean economy. But to do that, the country needs to put better policies in place to counter ocean acidification.
Don’t dismiss what science has to say about the fate of coral reefs.
Marine scientists have been accused of being biased towards 'doom and gloom'. But it's not bias if the outlook for coral reefs really is gloomy.
Corals grow better in the more alkaline ocean conditions that existed in pre-industrial times.
By artificially going 'back in time' to more alkaline ocean conditions, researchers have shown the damage that ocean acidification is already doing to the Great Barrier Reef.
The Great Barrier Reef is made up of thousands of individual reefs.

Ocean acidification will hurt some parts of the Great Barrier Reef more than others.
Adult corals need a good developmental start to establish themselves on the reef.

Without action to curb the rising acidity of our seas, corals will start to develop deformed skeletons at a crucial young stage of their lives.
The mussel hustle.
Shellfish will have more brittle shells as oceans get more acidic – making them more vulnerable to predators. New research gives a fascinating glimpse into how they will adapt.
Jelly invasion: is this a vision of the future for our oceans?
We know a lot about the potential negative effects of ocean acidification on marine creatures. But might some species actually benefit? The answer is yes, but this isn't necessarily a good thing.

Many corals can't make it through the bleaching events caused by warming ocean waters. But some can – and scientists are trying to learn more about the sources of their resilience.
Coral reefs are vulnerable to both rising temperatures and acidifying oceans.

It should not be assumed that policies intended to deal with the climate will simultaneously stop ocean acidification.
Tuna and other top predators could run out of food in warming seas.

Over the past five years we've seen a significant increase in research on ocean acidification and warming seas, and their effect on marine life. Overall, unfortunately, the news is not good.
Gamba Grass is altering fire regimes in the Top End, threatening human life and property, natural assets including Kakadu and Litchfield National Parks, and compromising savanna burning programs.
One of the Australian government's new research priorities is "environmental change". But can be hard to know how to tackle such huge and interlinked issues as climate change and species extinctions.
Time to get cracking: a Canadian research vessel in the Arctic.

A melting Arctic means new areas will be open to commercial fishing but scientists – and bordering countries – say they need time to study the ecological and economic risks.
Icy waters off the western Antarctic Peninsula.
Hundreds of meters below the surface of the freezing ocean surrounding Antarctica, the seafloor is teeming with life. The animals living there have no idea that an army is on the brink of invading their tranquil environment.
The tropical orange blotch surgeon fish has been moving south into New South Wales.

As warmer seas move further south, tropical wildlife is going with them, giving us a dramatic insight into how global warming is changing our oceans.
Acehnese fishers are among the quarter of the world’s population who live on the coast, and for whom climate-driven changes to the oceans would make life much harder.

Failing to stick to the world's agreed global warming limit of 2C won't just affect the atmosphere - it will play havoc with the oceans too, potentially ruining ecosystems on which much of humanity depends.
The Great Barrier Reef is one of the most magnificent wonders of our world.
With the United Nations set to decide on whether to list the Great Barrier Reef as officially in danger, we look at the various threats to the reef's survival, starting with the biggie... climate change.
