Lets roll the dice.
Almost everyone, including the media (which is politically driven and often ignorant of scientific fact and/or method), seems to be taking all this the wrong way.
Global warming is exactly that, GLOBAL. It can not be related to or pinned on a particular local event such as the bushfires that are being debated here. Freak events occur regardless of general trends. Global warming is about a trend, an increase in average global tempreature over a reasonable period of time.
If you take all the tempreature measurements made by all the weather stations across the globe, and take an average of those measurements you see a long term trend of increase, whats more, the rate at which that increase is taking place is far higher than, or contrary to, that predicted by the natural cycles of the Earth's climate. In other words without the intervention of civilisation there would be less heat energy in the atmosphere.
At this time the differences are slight, to say that people died in the bushfires because of global warming is debatable. To say that more people died than usual is correct. To say that the weather conditions contributed to the higher than usual death toll is also correct. To say that these weather conditions are a result of global warming, is not yet certain.
However, the more we see freak weather events occurring, the more likely it is that global warming is to blame. The event becomes part of a continuing trend. The more events fit into the trend the stronger the evidence in favor of that trend. And this particular trend is contrary to any previously established pattern.
Our best scientific models are showing us of the posibility of global catastrophe, the more we study, the harder we look, the more we find the probability of such events increase.
Nothing is yet for certian, but I know where I am going to place my bet!!

P.S. Has anyone tried to insure a coastal home against flood damage recently??
