Recent marine heatwaves have devastated crucial coastal habitats, including kelp forests, seagrass meadows and coral reefs.
Marine heatwaves, like their land counterparts, are growing hotter and longer. Sea species in southeastern Australia, southeast Asia, northwestern Africa, Europe and eastern Canada are most at risk.
As extreme weather events, like Hurricane Florence, become more common it is time to ask what it will take for the world to finally tackle climate change. Encouragingly, there may be a historical precedent: Victoria London’s handling of the ‘Great Stink’, where growth had turned the River Thames into an open sewer.

From Greece, to the UK, to Japan and even Sweden, a slew of places in the Northern Hemisphere are suffering extreme heat. And the chances of extreme heat records tumbling are growing all the time.
It was a hot year for many Australians.
An annual assessment of the health of Australia's environment shows mostly stable conditions in 2017, but ecosystems on land and at sea suffered ever higher temperatures.
Our climate is going to get warmer, and we need to protect ourselves from heat-related illness.
Heatstroke is a medical emergency and often kills. But there are many processes in the body that occur between being exposed to heat and ending up in the ED – and warning signs to look out for too.
Tennis Australia recommends suspending play when the “wet bulb globe temperature”, which accounts for sun, air temperature and humidity, exceeds 34°C.
It seems obvious that a game should be suspended if it's too hot to play, but it's not as easy as implementing a maximum temperature.
Sydney is facing 50℃ summer days by 2040, new research says.
Future extreme heat is worse and coming sooner than you might think. Unless we mitigate and adapt we face increasing death rates.
Who set the guardrails on global temperature rise?
More and more research shows that we are likely to pass the 2 degree Celsius temperature limit much of the world has agreed on. Where did that limit come from, and what if we miss it?
