The measure is compiled by the Bureau of Meteorology. It dates back to 1910. A separate global reading prepared by the World Meteorological Organisation has 2014 the hottest year since international records began in 1880. Not a single year since 1985 has been below average and every one of the 10 hottest years has been since 1998.

That it's getting hotter is what economists call an empirical question – a matter of fact not worth arguing about, although it is certainly worth arguing about the reasons for the increase and what we may do about it.
