=== Atlas.6.5 Summary ===

<div id="h2-29-siblings" class="h2-siblings"></div>

There is ''very high confidence'' that the climate of Australia warmed by around 1.4°C and New Zealand by around 1.1°C since reliable records began in 1910 and 1909 respectively, with human influence the dominant driver. Warming is ''virtually certain'' to continue, with a magnitude roughly equal to the global average temperature. A significant decrease in April to October rainfall in the south-west of the state of Western Australia observed from 1910 to 2019 is attributable to human influence with ''high confidence'' and is ''very likely'' to continue in future, noting consistent projections in CMIP5 and CMIP6. Other observed and projected rainfall trends are less significant or less certain. Model representation of the climatology of Australasian temperature and rainfall has improved since AR5, through an incremental improvement between CMIP5 and CMIP6, and the development of coordinated regional modelling through CORDEX-Australasia. Snow cover is ''likely'' to decrease throughout the region at high altitudes in both Australia and New Zealand ( ''high confidence'' ).
