This term describes dramatic swings between different kinds of extreme weather.

How did Australia’s climate fluctuate before the large-scale burning of fossil fuels? Old records can help us find out.
Australia’s weather extremes are increasingly arriving back-to-back in a ‘weather whiplash’.
From wombat and mozzie surveillance to deciphering climate history and spotting star explosions, citizen scientists are instrumental in contributing knowledge.
The atmosphere now has the highest carbon dioxide levels in the last 800,000 years – and global heat records have toppled yet again. Coincidence? Of course not
Newspapers were writing about climate change more than a century ago. Here’s why it’s taken so long to start tackling it.
How does this compare to Australia’s previous floods? And can we expect more frequent floods at this scale under climate change? The answers aren’t straightforward.
With climate action more crucial than ever, the IPCC needs to communicate clearly and strongly to as many people as possible. So how is it going so far?
Older records can tell us a lot about Australia’s pre-industrial climate, before the large-scale burning of fossil fuels tainted global temperature records.
Cold fronts swept south-eastern Australia, bringing snow and freezing temperatures. While snow is expected to decrease with climate change, cold snaps are likely to keep coming.
Last year saw plenty of warm weather around the country, but other notable events included dry months in the southeast, some very cold winter nights, and record-warm dry season days in the north.
High-quality climate records only go back to the start of the 20th century. But using handwritten letters, journals and tables, researchers have access to data going back to the 18th century.
Old climate records can help us understand what has happened in the past, and what will happen in the future.
