The climate ‘hiatus’ doesn’t take the heat off global warming

Over the past decade, warming air temperatures at Earth's surface appear to have slowed. But that ignores the vast majority of heat going steadily into the ocean. And, a new paper shows, that makes no difference to the long-term prognosis.

Why are Australia’s marine parks being reviewed so soon after they were signed off?

Australia's network of marine parks - a decade in the making and announced in 2012 - haven't been implemented yet, and the Abbott government has already placed the plans under review. Why the hurry?

Shark-counting divers off Costa Rica reveal limits of marine reserves

Divers at the famed Cocos site off Costa Rica record declines in a number of shark species – a sign that marine preserves are limited protection against illegal fishing.

Marine heatwaves threaten the future of underwater forests

Western Australia’s marine environment is unique. Two world heritage areas, the largest fringing coral reef in Australia, and more than a thousand kilometres of underwater forests, supporting incredible…

Six ways Australia is selectively reporting to the UN on the Great Barrier Reef

The Australian government’s latest report on the Great Barrier Reef, submitted to the UNESCO World Heritage Centre last Friday, has been carefully crafted and word-smithed, with many of its claims supported…

Ten years after the Boxing Day tsunami, are coasts any safer?

Ten years ago we witnessed one of the worst natural disasters in history, when a huge earthquake off the coast of Sumatra triggered a devastating tsunami which swept across the Indian Ocean. An estimated…

Your coastal town’s climate score? There’s a website for that

Australia’s coastal towns, many built around fisheries and tourism, are particularly vulnerable to climate change. South east and south west Australia are marine hotspots — they are warming much faster…

15 years from now, our impact on regional sea level will be clear

Human activity is driving sea levels higher. Australia’s seas are likely to rise by around 70 centimetres by 2100 if nothing is done to combat climate change. But 2100 can seem a long way off. At the moment…

Climate change threatens Western Australia’s iconic Shark Bay

In the summer of 2010-2011 Western Australia experienced an unprecedented heatwave — but not on land. Between December 2010 and April 2011, sea temperatures off the WA coast reached 3C above average, and…

Southern oceans heating up faster than scientists realised

The upper layers of the world’s oceans have been warming much faster than oceanographers realised over the past few decades…

Redrawing the map could reveal ocean garbage patch culprits

Most of us have littered at one time or another, and in the process we probably contributed to the enormous of amounts of plastic that enter the ocean every year, eventually ending up in one of the five…

Track boats with GPS to stop illegal fishers draining the seas

The ocean, seen from a beach or from a plane, seems vast, ancient and invulnerable. It’s hard to imagine that 90% of life on earth lives below the waves, across 1.3 billion cubic kilometres of water and…

Drought in store as El Niño’s western cousin to grow stronger

Over the past few months, a lot of attention has been paid to the potentially strong El Niño event brewing in the Pacific Ocean. But there is also the potential for an emerging climate phenomenon in the…
