You mean like how this year is the latest in a long run of parts of the country breaking temperature records year round, as well the general uptick in mean-surface temperature since 1950 - http://www.bom.gov.au/climate/current/annual/aus/2018/#tabs=... ?

Or that we're in one of the longest droughts on record, with many rural towns prior to this (and still actively) running out of water (as in, no water in the pipes at all), and Sydney on water-restrictions?

Mysteriously, Australia has been having a multi-decadal run of consistently seeing the factors which would be worsened by global warming, get worse.

What would you consider as compelling evidence?
