The 2021 Pacific Northwest heatwave outstripped even the most severe climate prections. A new study simulated 45,000 years of weather at Seattle Tacoma airport to try and figure out why.

New research has unravelled the mystery of why sea sponges die when the water gets too warm. The cause of death appears to be the sudden loss of microbes that usually act to detoxify sponge tissue.
The oceans are getting hotter, with a likely El Niño and climate change responsible.
El Niño can trigger intense and widespread periods of extreme ocean warming known as marine heat waves. They can devastate marine life.
We know the oceans are warming, but we have fewer measurements in coastal waters where most fisheries and aquaculture operate. Now the fishing industry is helping scientists to track the changes.
The first comprehensive audit of marine life around Australia, deploying an army of volunteer research divers alongside scientists, has revealed southern reefs are suffering the most.
Climate change is adding energy to the atmosphere and the oceans. This in turn fuels more intense storms and heavy rainfall.
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.
