Almost all of Australia, including the capital cities, is very likely to experience another "unusually warm" winter, according to the Bureau of Meteorology's (BOM) official winter outlook.

A new report by a team of international climate scientists shows the staggering amount of extreme heat days each country across the globe experienced last year, with the majority made more likely by human-induced climate change.

Eastern Australia will continue to shiver through unusually cold temperatures for the rest of the week, with some capitals facing their coldest morning of the year so far, days out from the winter solstice.

Large parts of Australia have woken to their coldest morning of the year in the past two days, as icy weather continues to blast Australia's east ahead of the winter solstice.

If you're in eastern Australia, it's been pretty hard to avoid small talk about the cold this past week.

Global average temperatures have been at or above the Paris Agreement target of 1.5C for 12 months in a row.

Despite the varying climate, the capitals – outside of Darwin – all have one thing in common. They've just shivered through what is historically their coldest week on the calendar.

It feels like the seasonal switch has already been flicked in the eastern states.

Heatwaves loom as a growing threat to humanity in a warming climate. This summer alone, in the northern hemisphere, thousands have died during extreme heat events. It's driving researchers to find out more about the point when heat turns deadly.

Large parts of Australia are set for an early taste of summer starting this weekend, along with elevated fire danger, as a tongue of heat spreads across the country.
