* Australia's climate has warmed by an average of 1.47C since national records began in 1910.

* Sea surface temperatures have increased by an average of 1.05C since 1900, leading to an increase in the frequency of extreme heat events over land and sea.

* There has been a decline of about 15 per cent in April to October rainfall in the southwest of Australia since 1970. Across the same region, May to July rainfall has seen the largest decrease, by about 19 per cent since 1970.
