Doug,
You tell someone to do their research and back up their claims. Then you make a statement that 'average temperatures and weather patterns haven't changed much at all since
Cook arrived'. Your research and evidence to back up this claim is a graph showing that
Adelaide's average temperature hasn't changed much since 1910.
Well, I'll see your
Adelaide and raise you a
Melbourne where 'there is an apparent significant warming trend since the 1950s' (The Greenhouse Effect and Climate Change - Australian Bureau of Meteorology). Up by over one degree Celsius since 1910.
Or how about the global trend? 'During the last decade or so, global annual mean surface temperatures have been among the
warmest on the instrumental record.' - From the same source (BOM) which you used in your response. Or this 'The annual mean temperature series over Australia is generally consistent with the global trend in showing warming, particularly in recent decades However, this warming trend is not uniform throughout the country'. Presumably this accounts for your ability to use
Adelaide as an example to back up your argument.
Now don't get me wrong, I don't have a really firm view on the climate change issue one way or another. As robak pointed out, the full understanding is probably beyond most of us and I am prepared to admit that it is certainly beyond me. But I think it is a bit rich to tell others to back their point up with research and data, then back your own up with a selective range of evidence and unsubstantiated statements which only support your obviously strong stance.
Matt.
