WATCH: What's the state of Australia's climate?

Get the facts in this overview video with key takeaways from the State of the Climate 2020 report.

Co-developed with the Bureau of Meteorology, this sixth, biennial report draws on the latest climate monitoring, science and projection information.

The 2020 report is a synthesis of our current understanding of climate in Australia and includes new information about Australia’s climate of the past, present and future.

Our climate shapes the lives of all Australians.

So how is our climate changing and why?

Despite some slowdown during COVID-19,

global carbon dioxide concentrations are now higher than any time in the last 2 million years.

The enhanced greenhouse effect is a major driver of our changing climate.

[The screen shifts to a graph showing temperature changes over time, text on the right-hand reading Australia's temperatures continue to rise with a graph illustrating an upward trend since 1900]

Australia's temperatures continue to rise, with more frequent and intense heatwaves. These trends are projected to continue.

The number of dangerous fire weather days is increasing,

with longer fire seasons for the east and south of the country.

Over time, long-term rainfall patterns have shifted.

The southern half of Australia is becoming drier during the cooler months,

and combined with warming temperatures, there will be more time spent in severe drought.

In contrast, wet season rainfall over central and northern parts has increased.

[The scene changes to an animated ocean with arrows darting into the water]

[Text comes on screen reading our oceans are acidifying with multiple down arrows next to PH to symbolize the increased acidity of the oceans]

The oceans are absorbing some of the additional carbon emitted by humans.

As this happens they are acidifying.

Ocean temperatures continue to increase,

[The animation shows us a view over a clear ocean with the text ocean temperatures continue to increase]

and marine heatwaves are becoming more frequent and severe.

As a result of the warming oceans, sea levels are rising and the rate of increase is accelerating.

[An animated graph shows the rising sea levels since 1880 and the text above reads sea levels are rising]

Looking ahead, all these trends are projected to continue, though reducing global emissions

will lead to less warming and impacts.

With better science than ever before, State of the Climate can help Australians better plan and adapt for our changing climate.

Australia is experiencing climate change

Australia's changing climate

  • Australia’s climate has warmed on average by 1.44 ± 0.24 °C since national records began in 1910.
  • This long-term warming trend means that most years are now warmer than almost any observed during the 20th century.
  • The frequency of extreme heat events is increasing
  • There has been a decline of around 16 per cent in April to October rainfall in the southwest of Australia since 1970. Across the same region May–July rainfall has seen the largest decrease, by around 20 per cent since 1970.
  • Rainfall and streamflow have increased across parts of northern Australia since the 1970s.
  • There has been a decrease in the number of tropical cyclones observed in the Australian region since 1982.

Greenhouse gas concentrations in the atmosphere continue to rise

Greenhouse gases

  • Global average concentrations of all the major long-lived greenhouse gases continue to rise in the atmosphere.
  • In 2019 the global average CO2 concentration reached 410 ppm.
  • Despite a decline in in global fossil fuel emissions of CO2 in 2020 associated with the COVID-19 pandemic, this will have negligible impact in terms of climate change.
  • Atmospheric CO2 continues to rise, and fossil fuel emissions will remain the principal driver of this growth.

Our oceans are changing

Oceans and cryosphere

  • Global sea level rise is accelerating, reaching a rate of over 3­ cm per decade in recent decades.

  • Global mean sea level has risen by around 25 cm since 1880. Half of this rise has occurred since 1970.

  • Average sea surface temperature in the Australian region has warmed by more than 1 °C since 1900.

  • Warming of the ocean has contributed to longer and more frequent marine heatwaves.

Australia will experience ongoing future climate changes

Future climate

  • Global average concentrations of all the major long-lived greenhouse gases continue to rise in the atmosphere.
  • In 2019 the global average CO2 concentration reached 410 ppm.
  • Despite a decline in in global fossil fuel emissions of CO2 in 2020 associated with the COVID-19 pandemic, this will have negligible impact in terms of climate change.
  • Atmospheric CO2 continues to rise, and fossil fuel emissions will remain the principal driver of this growth.
