At a glance
- Under a high greenhouse gas concentration scenario (RCP8.5), temperatures in Australia will increase by between 2.8 and 5.1°C by 2090 compared to 1986-2005.
- Rainfall trends are more uncertain, however rainfall amounts are expected to decrease over southern Australia, accompanied by more frequent and more severe droughts.
- Global sea levels are expected to increase by 45 to 82 cm by 2090 for the high concentration scenario. These levels may be higher if a tipping point is reached which commits one or more land-based ice sheets to irreversible melting. Projected increases around Australia are very similar.
- Extreme high sea-level events will occur more frequently in future, increasing the risks of flooding and erosion in coastal areas.
- In line with global trends, seawaters around Australia are becoming more acidic, as the oceans absorb some of the CO2 released by human activities."
