Autumn 2016 was Australia's hottest, beating the previous record set in 2005.
The records keep on falling.

Another month, another broken temperature record. Scientists are already confident 2016 will be the hottest year ever, a record only set in 2015.
Some materials and surfaces radiate much more heat (red areas) than others, as can be seen in this thermal image of Arncliffe Street in Wolli Creek, Sydney.
Hot spots occur at the scale of where people live – the building, the street, the block – which means urban design and building materials have profound implications for our health and well-being.
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?
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.
Health issues from extreme heat are a reality for many in Africa.
Africa must find ways of dealing with extreme heatwaves or suffer a range of health problems, including fatalities.
We all love a shady courtyard, but it's tough to know just how effective trees are at beating the heat.
Gas bill got you feeling grey? A reverse cycle air conditioner could save you money.
Heating your home using electricity is not just cheaper, it's more efficient and can be considered renewable.
All that precious heat is going to waste.
Heat should be valued, preserved and put to use
High temperatures can make students restless, listless and unable to pay attention.
High temperatures have been found to have a negative effect on learning, so how are schools in northern Australia coping?
Keeping office workers from feeling too hot or too cold is no simple task.
If you work in an office, chances are you or the person sitting next to you has grumbled about it being too hot or cold.
Heat is costing the Australian economy through productivity losses.

Heat cost Australia nearly A$7 billion in 2014, which is bad news given climate forecasts of hotter and more frequent heatwaves.
Magnets have mysterious powers – now shown to influence heat and sound.

Sound waves are made of particles called phonons. New research shows they're affected by magnetic fields, with researchers able to steer heat magnetically.
Women often report that they feel colder than men in the same environment.
Fever indicates a problem, but is there anything wrong with feeling excessively cold rather than actually being cold?
If you’re not regularly active, extreme exercise and exercise in extreme heat is unwise.
Exercise alone can be hard, but exercising in the heat is a whole lot harder. Put simply, this is due to the balance between how much heat the body generates and how much it is capable of losing.
Well, maybe it’s not quite
this electrifying, but the prototype is pretty cool.
