A key aspect of successful agriculture is being able to manage seasonal variability and climate change.
One way that helps to do this is by looking at annual rainfall and temperature information over the years – past trends can aid in predicting what our climate will be like in the future.
We have prepared posters with this information, based on historical records from 1910 to 2019.
These two posters show that:
- rainfall variability will continue to be driven by our key climate drivers.
- recent decades have been hotter.
Climate change projections successfully predicted this trend and maximum temperatures is expected to continue to rise in future decades. This is caused by heat trapping greenhouse gases in the atmosphere.
Annual rainfall decile maps 1910–2019
This poster shows rainfall values across across Australia since 1910.
You can see how longer term annual rainfall has been variable over the years.
This variability will likely continue into the future and is driven by our key climate drivers (see Understanding weather, climate and forecasting).
