Anthropogenic warming is improbable. There is no clear evidence of it only a lot of suspect data and interpretations mostly based on simplistic models. As new and more reliable data is coming to light past assumptions are being repudiated.
All the tiny changes in global temperatures and sea levels currently being recorded are within normal fluctuations. Nothing extraordinary or unprecedented climate-wise is occurring.
Regarding Australia I have researched online the BOM's recorded data for the past 100 years and there is very little change in anything. Overall there is slight warming in most areas but not enough to say it is a trend, and not enough for anyone to notice. Also there is no significant increase in the rate of warming indicated over the past decade.
Out of interest, new data (corrected for past errors by using only reliable sources) from the United States shows their last four hottest recorded years were in order 1934, 1926, 1996 and 2004. There is no trend in that.
