    You're the one always banging on about extremes (or lack of). I'd say that 39 degrees in Sydney in October quite is extreme, don't you think?

    Aren't airports temp typically hotter anyways? Because of all the asphalt?

    I'm confused about somebody debating about temps not increasing for 17 years then stating that temps have nothing to do with climate change???

    If you read my posts, I was referring to 'extreme events' like floods, cyclones, droughts etc. You know, the ones that are so catastrophic that humans may cease to exist by 2030. A hot day here and there is not an 'extreme event'. We will always set records, both hot and cold ones.

    The ABC needs to get their facts right. The previous record, using the observatory hill station, was 38.2C on 13 Oct 2004. Not 2008. The hottest Oct day in 2008 was 35.0.

    Not really. Thermometers are supposed to all be standard in their siting IAW the World Met Organisation. They do not all follow this unfortunately - which opens up another can of worms regarding dodgy data and the loss of thousands of temperature sites.

    Well last I checked, extreme heat can cause bush fires. Is that not catastrophic enough?

    They can add to a fire, just like wind. But more importantly, poor fuel management and burnoff control are major factors.

    A bushfire would not be too concerned about a 0.8C change in temperature.

    On a side note, there has been no increase in bushfires due to 'global warming'.

    I just want to put a little perspective around this.

    One of the biggest issues of increased temperatures if the adverse effects it will have on a lot of life forms. Evolution is the process in which these life forms have developed to the particular features, characteristics and practices they currently exhibit. The thing is that evolution is an incredibly slow process.

    The earth is estimated to be 4.5 billion years (4,500,000,000) old.

    It took a billion years just to get simple celled organisms. The first primates are estimated to have appeared 60 million years ago.

    In regard to the barrier reef, the earliest evidence of complete reef structures is estimated to have been 600,000 years ago and the current, living reef structure is believed to have begun growing on the older platform about 20,000 years ago.

    When we talk about 15 years, 17 years etc how do you really think that compares in the scheme of things?

    The fact remains that humans are responsible for emitting amounts of gases in the atmosphere that are impacting climates above and beyond natural cycles and thus life on earth as we know it.

    Of course! *Reaches for air con remote control*

    Hmm, my air con runs off electricity that requires fossil fuel burning and well, um, there might be a hiccup with that...
