In a warmer future, ocean carbon sinks could help stabilise our planet

15 Feb 22 - We think of trees and soil as carbon sinks, but the world's oceans hold far larger carbon stocks and are more effective at storing carbon permanently.

Here’s how top predator species might buffer climate change impacts on biodiversity

27 Jan 22 - Sometimes even a finger-length fish can make all the difference in an ecosystem. As many of the world’s wild places confront a double-whammy of a warming climate and vanishing species, new research suggests that predators as small as the lowly sculpin could help dampen ecological turmoil triggered by heatwaves.

Companies backing kelp may be rushing ahead of the science

20 Sep 21 - Sinking seaweed could sequester a lot of carbon, but researchers are still grappling with basic questions about reliability, scalability and risks.

Climate change playing havoc with Chagos Archipelago

4 May 21 - The Chagos Archipelago is one of the most remote, seemingly idyllic places on Earth. Coconut-covered sandy beaches with incredible bird life rim tropical islands in the Indian Ocean. But as Sam Purkis writes in the Conversation climate change threatens everything that is unique about the Chagos Islands.

Warming waters could see fewer common fish

10 Jul 20 - As many as 60 per cent of the world's fish species could struggle to breed and reproduce if climate change causes the Earth to warm by 5deg over the next 80 years, according to a new study.

Map of uncharted ocean beds takes shape

22 Jun 20 - The ocean floor is less well known than the surface of Mars and charting it could help show how oceans impact the earth's climate.

Sea warming spurs marine life to rapid migration

16 Jun 20 - Far from the sunlight and even at the lowest temperatures, ocean warming is making marine life uncomfortable.


It's up to us by how much sea levels will rise

22 May 20 - It’s a racing certainty that sea levels everywhere will go on climbing. Unless the world’s nations act to contain global warming, by 2100 the tides around the world will be one metre higher. And by...

Oceans could rebound in 30 years — if we act now

7 Apr 20 - The glory of the world’s oceans could be restored within a generation, according to a major new scientific review.

Poles attract marine life avoiding rising heat

7 Apr 20 - In a warming ocean, some species will swim, others sink. But all agree: the poles attract marine life without exception.

Hunger threat as tropical fish seek cooler waters

3 Mar 20 - Stocks of tropical fish that have provided vital protein for local people for generations may soon disappear as the oceans warm, leaving empty seas in their wake, scientists believe.

Race to exploit seabed set to wreak havoc

29 Jan 20 - New research warns that ‘blue acceleration’ – a global goldrush to claim the ocean floor – is already impacting on the environment.

Seas losing oxygen at unprecedented rate, say experts

9 Dec 19 - Oxygen in the oceans is being lost at an unprecedented rate, with “dead zones” proliferating and hundreds more areas showing oxygen dangerously depleted, experts have warned.

BIG PLASTIC: Don't blame us, it's those public litterbugs

25 Nov 19 - Plastic manufacturers believe they are not to blame for the material choking the world’s oceans. They point the finger at litterbugs.

Look back 125,000 years and sea-level rises are terrifying

8 Nov 19 - Sea levels rose 10 metres above present levels during Earth’s last warm period 125,000 years ago, according to new research that offers a glimpse of what may happen under our current climate change...

Dumped fishing gear biggest ocean polluter

7 Nov 19 - Lost and abandoned fishing gear which is deadly to marine life makes up the majority of large plastic pollution in the oceans, according to Greenpeace.

Seabed carbon storage could help in climate crisis

30 Sep 19 - Climate scientists say seabed carbon storage could be a new ally to help reduce greenhouse gas emissions by a volume greater than all the carbon dioxide pumped into the atmosphere from the planet’s...

RETURN OF THE BLOB? Marine heatwave settles over Pacific

10 Sep 19 - The Pacific Ocean off the western coast of North America is five degrees hotter than usual after warming at an unusually rapid rate.

Changing waves add to coastline worries

20 Aug 19 - A warming planet will alter ocean waves along more than 50 per cent of the world’s coastlines, according to research published today.
