New Zealand may see more sponge bleaching as the northern coastlines are already experiencing almost continuous marine heatwave conditions, expected to extend into the coming summer.
Our oceans have absorbed almost all the extra heat we’ve trapped with our emissions. Now we know how this heat moves in ocean currents.
While official data is yet to be released, this year’s Mediterranean marine heatwave will likely have devastating ecological consequences.
Three chief authors of the State of the Environment Report provide its key findings. While it’s a sobering read, there are a few bright spots.
Efforts to save the reef aren’t tackling the main cause: climate change. What we need from our next federal government is strong leadership to avert the climate crisis.
Coral reefs that suffer widespread bleaching can still recover if conditions improve, but it’s estimated to take up to 12 years. And that’s if no more bleaching events occur.
For the first time, an IPCC climate report has assessed evidence that weather and climate extremes are already affecting mental health — and are likely to worsen.
Marine heatwaves will happen so often that reefs will struggle to weather successive bleaching events.
2021 was NZ’s hottest year on record, and the current summer heatwave is a reminder that our biodiversity is already being affected.
The old ways of keeping giant clam species healthy won’t work with climate change. We need new techniques - and fast.
Can we breed kelp and other keystone species to survive warming and marine heatwaves? These techniques have promise – but they’re not a silver bullet.
Australia’s southwest is a biodiversity hotspot - and it’s also a climate change hotspot. Something has to give.
The indirect losses from one heatwave in Western Australia caused A$4.14 billion per year worth of damage.
The Blob, a long-lasting mass of warm water, sat off the Pacific coast of North America for years, bringing new species to formerly cold waters. What allows some to survive while others fade away?
The oceans around New Zealand are warming faster in winter than in summer. During the winter of 2021, most coastal areas were warmer than usual, and this is likely to bring more storms during summer.
Academic research can shed light on crucial questions about what life on Earth will be like under the most plausible emissions scenarios. And a warning: the answers are confronting.
The latest IPCC report makes it clear we can no longer stop the seas from rising, but we can still control how much and how fast sea levels change.
Australia may warm by 4℃ or more this century, the IPCC has found. As these IPCC authors explain, there is no going back from some changes in the climate system.
During a 2015 heat wave, scientists watched as a coral reef died before their eyes. By the end of the century, almost all the world’s corals will be gone if climate change continues at this pace.
Researchers found 16% of coral species have not been seen for many years. This finding is alarming, because local extinctions suggest global extinctions may be looming.
