New South Wales has just had its hottest summer on record – an event that was made 50 times more likely by humans' impact on the climate.
Cows don’t do well in the heat.
As the climate changes and extreme weather effects become more common, cattle and other livestock are becoming more stressed.
Emergency crews tackle a bushfire at Boggabri, one of dozens across NSW during the heatwave.
Heat records have tumbled across New South Wales as the state suffered through the weekend's heatwave. A new analysis shows that climate change made this kind of event much less of a rarity.

2016 is the third consecutive hottest year on record. How can we adapt?
Cyclone Oswald caused flooding that forced the evacuation of more than 100 patients from Bundaberg Hospital to Brisbane in January 2013.
Most of our hospitals were not designed to cope with the health impacts of future extreme weather. And hospital infrastructure has not been adapted to secure health care during such events.
When New South Wales burned in 2013, Tony Abbott was quick to point out that individual events can’t be attributed to climate change. But they can.

The science of attributing extreme weather events to human-induced climate change has evolved rapidly in recent years. But how we communicate it to the public has not kept pace with this advance.
Australia’s oceans are heating up.
The new State of the Climate report outlines Australia's rising temperatures and its regional rainfall declines - and the trends that are locked in for the coming few decades due to greenhouse emissions.
Huge swathes of Tasmania have burned this year.

A comprehensive analysis of Tasmania's natural disaster risks has identified bushfire as the biggest threat, alongside emerging issues such as disease epidemics and heatwaves.
An electric fan cools you down in extreme heat, but not if you're old.
The Great Barrier Reef is already feeling the effects of climate change.
Limiting global warming to 1.5℃ already looks out of reach, so where do we go from here?
Victoria was one of several states to suffer bushfires as temperatures soared in late 2015.

2015 was the world's hottest year on record. The US State of the Climate report has rounded up the litany of temperature and other records that were broken all over the globe.
Around 15,000 Parisians died in the August 2003 heatwave. So what lessons have been learned?
Scorching temperatures in Jammu, northern India. This month has seen records smashed in nearby Rajasthan.
The city of Phalodi has set a temperature record for India, hitting 51℃. Until now, India's smog problem has curbed extreme temperatures. But that could be about to change.
Tasmania’s bushfires damaged pristine bushland and stretched emergency services to the limit.

This summer has seen Tasmania suffer through drought, bushfires, floods and the worst marine heatwave on record. Is this what life under a climate-changed future will be like?
Bushfires and heatwaves are expected to increase and significantly impact on Australian cities and urban communities.
How well does the 'smart' city respond to the devastating scale and impact of urban heat threats such as bushfires and heatwaves?
Nice day for the beach. In fact there have been rather a lot of those in Sydney lately.

Sydney is in the process of smashing the record for the longest run of days above 26℃. Weather, El Nino and climate change are all playing their part.
Extreme weather could trigger ecosystem collapse, including mass tree deaths.

Extreme weather will affect people and animals, as well as whole ecosystems. Research using satellites shows that ecosystems worldwide are vulnerable to collapse.
The cover that trees provide transforms cities into much more hospitable places, especially in hot weather.
Six years after Black Saturday, it's worth remembering that heatwaves kill more people than bushfires do, so shade can be a life-saver. But tree cover and shade are not evenly distributed in cities.
Rural southern Australia has been drying out over the past several decades. Pictured here, Burra in South Australia.
Australia is the land of drought of flooding rains, driven by events such as El Nino. But despite this variability, some parts of Australia are clearly drying out.
A hot end of the year contributed to Christmas Day fires in Victoria.

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.
