The State of the Climate Report 2022, released this week by the CSIRO and the Bureau of Meteorology, says changes to weather and climate extremes are happening at an increased pace across Australia.
The report, released every two years, shows an increase in extreme heat events, intense heavy rainfall, longer fire seasons and a rise in sea levels.
CSIRO Climate Science Centre director Dr Jaci Brown said concentrations of greenhouse gases, such as carbon dioxide, were the highest levels seen on Earth for at least two million years.
“The concentrations of greenhouse gases in the atmosphere are continuing to rise, and this is causing Australia’s climate to warm,” Dr Brown said.
Dr Brown said the report documented the continuing acidification of the oceans around Australia, which have also warmed by more than one degree since 1900.
“The warming of our oceans is contributing to longer and more frequent marine heatwaves, and this trend is expected to continue,” Dr Brown said.
“We’re seeing mass coral bleaching events more often and this year, for the first time, we’ve seen a mass coral bleaching on the Great Barrier Reef during a La Niña year.
“The rate of sea level rise varies around Australia’s coastlines, but the north and south-east have experienced the most significant increases.”
BOM Climate Environmental Prediction Services manager Dr Karl Braganza said the report projected increases in air temperatures, more heat extremes and fewer cold extremes in coming decades.
“Australia’s climate has warmed on average by 1.47 degrees since 1910,” Dr Braganza said.
“We’ve seen contrasting rainfall trends across the north and the south of the country.
“There’s been an overall decline in rainfall between April and October across southern Australia in recent decades, but in northern Australia, rainfall has increased across the region since the 1970s.”
During La Niña events in 2021-22, eastern Australia experienced one of its most significant flood periods observed.
The report shows heavy rainfall events are becoming more intense and the number of short-duration heavy rainfall events is expected to increase in the future.
Dr Braganza said the length of fire seasons has increased across the country in recent decades.
“We’re expecting to see longer fire seasons in the future for the south and east, and an increase in the number of dangerous fire weather days,” he said.
State of the Climate 2022 is the seventh report in a series by the Bureau of Meteorology and CSIRO.

What a load of woke socialist lefty greenie garbage. Who funds this crap? Go woke and we go broke. It’s called weather. History shows that the climate runs in cycles along with the seasons.
Those “woke, socialist, lefty greenies” are actually CSIRO and Bureau of Meteorology scientists and researchers who have spent years, probably decades, learning their trade. They have access to data from monitoring sites around the world, real-time satellite information and some of the best computers on the planet to model that data.
But what would they know, hey? They are probably drinking soy lattes and sipping chardonnay as they plot the downfall of the west.
