Perth Climate- less rain, warmer, more fires

Western Australia government websites state that;

"Western Australia's climate has changed over the last century, particularly over the last 50 years. Average temperature has risen about 1°C. Rainfall has increased over the north and interior, declined along the west coast, and declined by about 20% over the lower south-west" (main agriculture region). "Fire risk has increased across the state. The decline in rainfall over the south-west is consistent with increasing greenhouse gas concentrations and cannot be explained solely by natural climate variability or changed land use, such as land clearing." (https://www.agric.wa.gov.au/climate-change/climate-trends-western-australia).

I have graphed rainfall vs cumulative land clearing and there appears to be some correlation between land clearing (16,000,000 hectares) and decreased rainfall (30-40% fall) since 1920.

Assuming 156 trees per hectare (WWF) and no regrowth, Western Australia would have to replant 2.5 billion trees to replace 16,000,000 ha of cleared land- this may help reverse the fall in rainfall and have the added benefit of; increased native wildlife, CO2 capture, increased tourism, etc.

The land area cleared is about the size of Florida or larger than the area of Greece.
