This summer's record-breaking coral bleaching on the Great Barrier Reef was made 175 times more likely thanks to climate change.
Australia’s mountains may be small but each year they deliver enough snow for winter sports.
Australia's snow season is notoriously fickle - so what determines whether we'll get a good fall?

The summer of 2015-2016 was the hottest on record for Australia's oceans.
Million-year-old ice likely lies more than 3km below Antarctica’s surface.

Ice cores tell us vital information about how the world's climate has changed - and how it will change in the future.
Pencil pines are found nowhere else in the world, and are extremely sensitive to fire.
Bushfires are threatening Tasmania's World Heritage area and ancient plants, warning us of a possible future under climate change.

El Niño dominated global climate in 2015, but in Australia the story was more complicated. 2015 was Australia's fifth warmest year on record, and saw the return of very dry conditions to parts of Australia.
From making renewable energy practical to revolutionising farming, the chemicals industry could make a huge contribution to the environment.
Floods during warm periods of human history likely inspired the Noah’s Ark myth.

2015 will likely be a degree warmer than before people started pumping greenhouse gases into the atmosphere. The last time the world was this hot wasn't great for civilisation.

The Millennium Drought was bad, but the most detailed record of droughts since 1500 reveals there were far more severe super-droughts in the past.
Caves, such as Cathedral Cave at Wellington Caves Reserve, can tell a great deal about past climate.

A new study looking at mineral deposits in caves is revealing insights into climate from the distant past.
When the Indian Ocean combines with El Niño dry conditions come to Australia.

We thought the big El Niño might not bring drought. And then the climate turned dry. And hot.
Low carbon choices such as solar power are essential for the African continent, if it intends to stop the harmful global warming effects.
For the sake of mitigating climate change, the African continent needs to make low carbon energy choices.
This summer’s El Niño is likely to bring more frequent heatwaves to a large swathe of Australia’s north and east.
The link between El Niño and heatwaves is complicated. But what we can say is that this summer's strong El Niño conditions are likely to bring more heatwaves to much of Australia's north and east.

A huge El Niño on the horizon bodes ill for drought and forest fire.
Is Australia’s 2030 climate target really going to protect the coal industry?
Australian Prime Minister Tony Abbott has said his government's 2030 climate target will be good for the environment and jobs – and good for protecting the nation's coal industry.
The large 1982 El Niño contributed to the Ash Wednesday bushfires that killed 75 people in south east Australia.
El Niño has arrived, it's getting stronger, and it's not about to go away soon. And already there are rumblings that this could be a big one.

Over the past 80 years sardine and anchovy have become icons of modern-day marine biology, oceanography and climate research.
South Africa’s tropical fish may be hardest hit with climate change.
Climate change will hit South Africa's fish population.
Gathering data at the calving front of the Ilulissat Glacier, Greenland.
To create accurate models that predict how ice sheets and oceans will react to changing climate, modelers need precise current data. One researcher heads to the ends of the earth to collect just that.
Future snows will mostly happen in big falls.
This weekend is predicted to be the coldest of the year in Australia. But it has otherwise been a slow start to the snow season, and my research shows that this is a sign of things to come.
