    Daytime temps were high, overnight were lower than average. Dry air will do that. Cloudless days make for higher maxima.

    So to confirm or debunk the above hot winter claim, what was the natural day average temperature for the 2017 Australian winter, and what is the long term average for this ?

    Overnight minima were the lowest in 20 years in some areas, the publicity was all about the daytime temps. Very much a mixed grill, the south has had a coldish winter, the north warmer than normal. There is no winter in the far north, anyway, the distinction being a warm "wet", Nov-April, and a warm "dry" the rest of the year.

    The average temperature would have been a different story.

    I'll have to agree with Mr. E. there, since as far as I can see all the supplied figures are only about the average maximum daily temperature, they don't say anything about how long those maximum temperatures existed, a split second doesn't have many influence unlike many hours, and it also doesn't take the night temperatures into account.

    Since the average temperature of a whole natural day (meaning 24 hours daily) is of a lot more influence than the only for a brief moment existing maximum temperature ± at noon every day, only the natural day (meaning 24 hours daily) average temperature for the 2017 Australian winter, compared to the long term average for this figure, will confirm or debunk the above hot winter claim, I believe.

    In my first post I supplied a link to the Australian Bureau of Meteorology. You can spend many happy hours reading all the in's and out's of temperature collection. For those of us graphically inclined here is a chart:

    "The warming in the ACORN-SAT dataset is very similar to that shown in international analyses of Australian temperature data and very closely matches satellite data and warming of sea surface temperatures around Australia. This agreement provides added confidence for decision makers, and reinforces our understanding of the changing climate."​

    Good news! When your grandchildren ask you "Where were you when the Holocene ended and the Anthropocene began?"' you might be able to say "I was there, and I helped!"

    We'll even have our own geologic markers, such as concrete and chlorines, plastic trash and radioactivity, plus massive disturbances such as caused by bulldozers and all sorts of boreholes. Kind of like "Kilroy was here", but different.

    That is a really short time period as ages go. It is also the natural trend as the Ice Age ends.

    I see this is still going.

    You're not even interested, are you? This is either pure willful ignorance, or a very good imitation of it. Standard operating procedure for anyone who wants to deny any field of science, be it climate science, vaccinations, evolution, or anything else. Regardless of the field being denied, the tactics are always the same.

    I'm sure you have seen the many long term graphs that are online. I'm sure it has been pointed out to you that the last ice age ended thousands of years ago, and that without anthropogenic forcing we would currently be in slight cooling phase.

    I'm also sure that you will continue to ignore any evidence that doesn't suit your preferred dogma.

    We've gone through this before, so I don't have much hope that you will be persuaded. However, here is a chart (which has been presented many times before) showing the estimated temperature for the last 12K years. For most of the last 8K years the average temperature has actually been falling -- which is not too surprising after the peak following an inter-glacial warming. The kicker is that in the last 100 years that downward trend has reversed, and not just a little, but big time. This chart shows that as of 2004 the temperature was back up to +.5C, but now, in 2017, it is closer to +1.0C.

    So it took about 8K years for the temperature to drop from about +0.5C to -0.5C, and then roughly 100 years to go from -0.5C to +1.0C. That's just crazy weird!

    Much effort has been made to explain this temperature rise anomaly by natural means -- change in solar output, orbital cycles, volcanoes, etc. Nothing fits the pattern -- except human-produced or human-triggered greenhouse gas emissions.

    The reporting of the "warm" winter was sensationalized, it cherry-picked one data set. I was under the impression that greenhouse warming had a greater effect of raising overnight temperatures. If the results had showed a distinct increase in that, and especially with the drier than average air, it would be more significant.

    Hope you're enjoying the sensation.

    Why cherry-pick, it put sensationalism ahead of facts. I have no doubt that winters are warmer, and summers are hotter, but "gilding the lily" is not helpful to the cause.

    More like a "wilting of the lily".
