Guest essay by Eric Worrall

According to the Australian CSIRO, Australia has already warmed by 1.4 ± 0.22C. But the CSIRO assures us bad things are happening, really. And they’re going to get worse. But they admit tropical cyclones have decreased, and while overall river flow is down, tropical wet season rainfall is up.

Key points

Australia

  • Australia’s climate has warmed
    on average by 1.44 ± 0.24 °C since national records began in 1910, leading to an increase in the frequency of extreme heat events.

  • There has been a decline of around 16 per cent in April to October rainfall in the southwest of Australia since 1970. Across the same region May–July rainfall has seen the largest decrease, by around 20 per cent since 1970.

  • In the southeast of Australia there has been a decline of around
    12 per cent in April to October rainfall since the late 1990s.

  • There has been a decrease in streamflow at the majority of streamflow gauges across southern Australia since 1975.

  • Rainfall and streamflow have increased across parts of northern Australia since the 1970s.

  • There has been an increase in extreme fire weather, and in the length of the fire season, across large parts of the country since the 1950s, especially in southern Australia.

Anomalies in annual mean sea surface temperature, and temperature over land, in the Australian region. Anomalies are the departures from the 1961–1990 standard averaging period. Sea surface temperature values (data source: ERSST v5, www.esrl.noaa.gov/psd/) are provided for a region around Australia (4–46 °S and 94–174 °E).

Australia’s climate has warmed since national records began in 1910. The oceans surrounding Australia have also warmed.

2 Report at a glance

  • There has been a decrease in the number of tropical cyclones observed in the Australian region since 1982.

  • Oceans around Australia are acidifying and have warmed by around 1 °C since 1910, contributing to longer and more frequent marine heatwaves.

• Sea levels are rising around Australia, including more frequent extremes, that are increasing the risk of inundation and damage to coastal infrastructure and communities.

Future

In the coming decades Australia will experience ongoing changes to its climate. Australia is projected to see:

  • Continued increases in air temperatures, more heat extremes and fewer cold extremes.
  • Continued decrease in cool season rainfall across many regions of southern and eastern Australia, likely leading to more time in drought, yet more intense, short duration heavy rainfall events.

• A consequential increase in the number of dangerous fire weather days and a longer fire season for southern and eastern Australia.

• Further sea level rise and continued warming and acidification of the oceans around Australia.

• Increased and longer-lasting marine heatwaves that will affect marine environments, such as kelp forests, and raise the likelihood of more frequent and severe bleaching events in coral reefs around Australia, including the Great Barrier and Ningaloo reefs.

• Fewer tropical cyclones, but a greater proportion projected to be of high intensity, with large variations from year to year.

As someone who lives in a warm part of Australia, I’ve got to say 1.4C warming since 1910 does not feel like the end of the world.

There is substantial evidence Australia experienced warm spells in the 1800s comparable to today. 435 people died in a heatwave in 1894, a few years before the starting point of the CSIRO’s warming trend. Even more people died in the early 1900s (see the top of the page). JoNova has some information about extremely warm Australian temperatures recorded in the 1800s which the CSIRO and BOM usually seem to leave out when preparing climate reports.

If the drop in rainfall in the south is a genuine trend rather than just an example of Australia’s multi-decadal climate noise, the CSIRO has a solution on the drawing board which would drastically increase water availability for Australian farmers; a tropical megadam scheme which could capture some of that increased wet season rainfall, instead of continuing to allow it flow out into the sea.

If our politicians stopped frittering cash on renewables and pumped hydro schemes which cannot possibly have a measurable impact on global warming, there might be some money to spare to ensure water security for our farmers, regardless of any changes to Australia’s rainfall patterns.

    • Spot on Roy. This is the key failing in the CSIRO/BOM “study” which invalidates all of its key conclusions.

      And the CSIRO/BOM have been doing this for some time now, frantic to avoid any meaningful discussion of the 1896-1903 Federation Drought which saw extreme temperatures, numerous business failures and a sizeable human death toll.

      The CSIRO/BOM have used a series of arguments why the Federation Drought weather data cannot be used in analysis of Australia’s modern temperature variations, including poor quality recording, different measuring equipment, different recording enclosures, site moves, lost data etc etc etc. You get the idea.

      And so almost all of the discussion and graphical presentation of the Australian temperature data starts in ca 1910, neatly and deliberately avoiding the Federation Drought extremes of only a few years earlier.

      When the Federation Drought temperature/rainfall data is included, a different picture emerges. And horror of horrors – some of the averaged annual temperature in that period were hotter than today!

  1. They obviously don’t take the temperature in southwest Vic , two long cold winters in a row here , so if its not everywhere then its not global and not happening.

  2. The starting point of the CSIRO’s warming trend 1910 was the coldest year of the 20th century. Just as all the global warming presentations that I attended between 2000 and 2010 had temperature graphs beginning in 1970 and ending in the El Nino year 1998.
    The year 1998 was only exceeded in temperature a tiny amount by 2016 but in the latest temperature graphs it has been retrospectively cooled to ensure a smooth uptrend.

    • You can confect an uptrend from data that actually conforms to a pure sine wave, i.e. actually has no real uptrend, simply by ‘creatively’ making sure you start the set in a ‘trough’. Easy Peasy and apparently its ‘science’. I actually saw it in a peer reviewed, published paper on sea levels where the sinusoidal element in the data was clear as day yet they did a trend line fit that was 80% due to the periodicity effect and maybe 20% showing an actual uptrend. If these people are being paid for schlok like that then who can blame people like me being highly skeptical?

  3. Eric,
    There is not only the “tropical mega dam scheme” which is valid in its own right but also the New Bradfield Scheme which will be well known to you.
    The New Bradfield Scheme proposes to channel some of the Tully River and 4 other rivers in North Queensland over the Great Dividing range to the Hells Gate dam and via pipelines and weirs ultimately to the Murray Darling system to re-invigorate and water vast stretches of inland Queensland, New South Wales and finally South Australia.
    At present Northern Australia is getting enormous amounts of water in the wet seasons much of which is wasted in flowing into the Coral Sea.
    As has been noted by all sides, Australia is getting hotter and WETTER not hotter and drier. The rainfall is in the North while it is the South East predominately with less rainfall.
    Bradfield’s scheme was workable in the 1930s and 40’s but was canned because the money was not available during the Depression and post-WW11 years.
    Sir Leo Hielscher ( now 93) and Sir Frank Moore have championed the Scheme for years and have slowly gained Federal and State Government support to the extent of closely investigating it and expending money for feasibility studies.
    The opposition seems to come from the Green Left (“ even the rains that fall won’t fill our dams again” etc.)
    The estimated cost is A$16 billion which is not excessive in these days of fantastic spending post CoVid.
    Australia desperately needs this Scheme if it is to be the food bowl of Asia which our politicians repeatedly trumpet.

          • During day by excess solar power … we have a ridiculous amount of excess electricity that is destabilizing the grid during daylight hours.

          • Nuclear like in the UAE which also produce electricity. The Nuclear reactors provide heat for high pressure steam. The high pressure steam passes through turbines which drive electricity generators and the low pressure steam is used for desalination. The UAE has started one 1400MWe unit with 3 more being built.

          • Australia doesn’t have any nuclear reactors bar a small one used to produce isotopes and Western Australia has none so we can hardly use that.

            There is no effective gas powered generation used for any desal plant in WA they are 100% powered from renewable energy because it is in useless excess when it is being generated and they have to dump it somewhere.

            The Perth desal plant gets it’s energy from the 80 MW Emu Downs Wind Farm near cervantes and the local Perth grid from Solar when in excess. Binningup desal uses excess renewable energy from the South West Interconnected System (SWIS) which is solar panels and wind farms in the south west mainly near Merredin. They both run as sheddable loads if the renewable energy stops.

          • It would appear to me that, although desalination is fairly expensive (energy intensive), one could use Off Shore Wind to power the process. I mean the wind is free right?
            Seems that a practically “Free Energy Source” would eliminate most of the operating costs for an energy intensive project that needs to happen at the coast anyway.
            Or is wind energy Not So Free

  4. Clearly one the key findings will be increased funding to the CSIRO so they can wrap more reverse engineered BS around their predictions of doom. What a pathetic alarmist outfit they have become.

    CSIRO, JCU, ABC, SBS and co, the alphabet soup of alarmist nonsense

  5. The CSIRO have swallowed the global warming pill,they should walk outside and sniff the air now and again.
    They may be pleasantly surprised that the world has not changed, perhaps if they actually did some research into history . Then some planetary and solar studies they may come to rather different conclusions.

  6. In the middle of OZ we have a salt lake around 32 Ft below sea level, it has been my thought for a long time to dig a channel from the top of OZ which have big tides and fill the lake. That amount of water would give rainfall and greening of a large amount of our desert could be achieved.

    • The channel would have to come from the south, much shorter, don’t know if it would work, the evaporation would make for a very very salty sea. Unless you could make the channel a couple of miles wide or more.

      • Don’t need to cut a channel, run a pipeline from whichever ocean or river source to the depression, prime the system by pumping water through it, and like siphoning gasoline from a higher tank to a lower gas can, the water will flow into the depression without further pumping and can be used to generate “green” power.

    • There’s been similar ideas going around to fill the Dead Sea in Israel, to generate power from the flowing water coming in from the Mediterranean and to freshen up the waters that have been getting lower and saltier, as well for other depressions in Libya, Egypt, I think even Death Valley in the USA. Australia seems to have an easier way in that water diversion project could be use to fill up the central salt flat with fresh water. The other projects I read about involved salt water being gravity siphoned into the depression and some of the electricity generated would go to desalination. Sounds like a great project for OZ, would turn the central desert areas into a paradise garden, and $16 billion is peanuts especially if GWs of power can come from from the dams.

  7. How accurate are the numbers before World War II?
    Was the starting point or decade unusually cool?

    What months / seasons of the year warmed the most?
    What time of the day/night warmed the most?
    An average, especially based on shaky data
    from over 100 years ago, hides what people
    really want to know. No one lives in
    an average temperature.

    Warming or cooling is to be expected.
    Our planet is always warming or cooling.
    Our planet has been warming for hundreds of years.
    20,000 years, from a longer term point of view.
    An average rise could consist of warmer winter nights?
    That sounds like good news.
    An average rise could be warmer summer days?
    That could be bad news.
    It is the details and data accuracy that really count.

    Why would anyone care about +1.4 degrees C. in 110 years?
    It warms +1.4 degrees C. every day of our lives after sunrise.
    Do people complain about that?
    Do they get depressed?
    Suicidal?
    I mean from the +1.4 degrees C. warming every morning.
    Not from reading the CSIRO report.

  8. With the state of Australia’s surface stations, some 40% being totally unfit for anything but propaganda,

    …. I really don’t see how CSIRO could possibly make any reliable claims about Australia’s temperature.

    Meanwhile UAH Australia shows no warming since 1998

    https://i.postimg.cc/XJLLfXs6/UAH-Australia-1998-onward.png

    (and no, it is not measured from the El Nino peak, because it didn’t exist in Australia)

    There was a step change though.

    Ans before that step change.. again, no warming.

    https://i.postimg.cc/g0tSQNCB/UAH-Aust-1980-1996.png

    Just like in the USA, there is absolutely NO CO2 WARMING SIGNAL…

    .., just El Nino surge/step, UHI smeared all over the place where it doesn’t belong….

    and, of course, the obligatory DATA ADJUSTMENTS and infilling.

      “Meanwhile UAH Australia shows no warming since 1998”

      It often pays to be suspicious of fred’s “no warming since…” claims, especially when his accompanying chart doesn’t contain a trend line. Add a trend line and you clearly see the +0.12C/dec warming trend reported in UAH AUST since 1998:

      https://i.postimg.cc/htshNXSp/UAH-AUST-1998-present.png

      “Ans before that step change.. again, no warming.”

      This time fred’s chart marked “UAH Aust 1980-1996” does contain a trend line . Alas, the data he shows actually stops in mid-1995, not Dec 1996. So what happens when you properly show UAH Aust from Jan 1980 to Dec 1996, as the chart’s title suggests? You guessed it, warming again, this time at +0.10 C/dec:

      https://i.postimg.cc/fTphyZ8D/UAH-AUST-1980-1996.png

      So what does the UAH AUST data tell us when we don’t chop out the bits we don’t like or don’t mislabel our charts or do show trend lines that we claim don’t exist? An overall warming trend of +0.19 C/dec; slightly faster than the UAH global land average over the same period:

      • You poor mathematically INCOMPETENT fool.

        Actually thinking that a 0.1C/decade MEANS anything..

        When the measurement error is far larger.

        TOTALLY HILARIOUS !!!

        And THEN you use the El Nino step to FAKE a linear trend..

        Will your mathematical INEPTITUDE and totally lack of mathematical understanding never end !!!

        You really have put the Final Nail in any credibility you might once have had.

        • “Actually thinking that a 0.1C/decade MEANS anything..”

          We can agree that over a period as short as you highlighted and over a single region no trend really means anything. Makes me wonder why you brought it up though?

          “And THEN you use the El Nino step to FAKE a linear trend..”

          Would that be the El Nino you said “didn’t exist in Australia”? Lol!

          “You really have put the Final Nail in any credibility you might once have had.”

          Really? I would have said that mislabelling charts and omitting trend lines you don’t like the look of then pretending they don’t exist is more of a challenge to someone’s credibility, but there you go.

      • You poor muppet.. Take out the El Nino and there is no warming.

        ABSOLUTELY ZERO evidence of any CO2 warming signal

        The fact that you have to use that El Nino shows that the only warming came from that El nino

        So sad you fell straight into the abyss left for an idiot like you to fall into …

        1… Do you have any empirical scientific evidence for warming by atmospheric CO2?

        2… In what ways has the global climate changed in the last 50 years , that can be scientifically proven to be of human causation?

        See if you are as incompetent as all the other AGW apologists. 😉

        • “Never interfere with an enemy while he’s in the process of destroying himself” TFN, by lowering WUWT’s standards Fred’s shouty, spittle-flecked lying is inadvertently helping.

          • Poor loy-dumb , yes I am watching you and Rusty destroy yourselves… .

            Do you or Rusty, even in your most DELUSIONAL anti-mathematical states, really think the measurements are accurate enough to detect a warming of 0.1ºC/decade?

            HILARIOUS. !!

            And if that is all CO2 is capable of. …. WOW !…. SCARY , hey !

            You are obviously have a TOTALLY IRRATIONAL and DELUSIONAL FEAR of atmospheric CO2…..

            and yet…… you have absolutely NO EVIDENCE that it is does anything except enhance plant growth.

            Do you have any empirical scientific evidence that atmospheric CO2 has increased the temperature over Australia by a SCARY 0.1ºC/decade ????????

            You are a JOKE, loy. !

          • Loy = 🙈🙉

            No warming between El Ninos.. END OF STORY.

            Only warming in the satellite data era is from those El Nino events.

            No amount of DENIAL on your behalf will change that FACT.

            Or you could just continue to yap mindlessly behind your ignorance.

          • Because of the STRONG SERIES of solar cycles, there has only been one medium La Nina in the satellite period, balanced by balanced by the 2010 El Nino.

            If you take them both out you are still left with a ZERO TREND .

            WAKE up and try to use your brain, if you can.

  9. Tried to load the report.
    Nothing happening. Do they turn the server off on weekends?

    Would like to know if they used the RCP8.9 scenario?

      • LdB,
        Have you discovered that we have a train of BOM historic temperature versions that cpntains at least, Raw, High Quality, AWAP, gridded, ACORN-SAT version 1, ACORN_SAT version 2 and now ACORN-SAT version 2.1.
        What does an author do on discovering that the meticulous paper just written, used an outdated version? What if the newest version affects the conclusions so academically derived? Geoff S

        • Calling it a meticulous paper is a bit rich it is a glossy piece of pseudo junk with some random graph and drawings on it.

          • LdB,
            I was discussing a hypothetical author writing a report that stands or fails depending on which version of data was used.
            Certainly, I was not commenting on the quality of the CSIRO report. Geoff S

  10. The January 2009 Heatwave in south east Australia was one on the worst in recent times.
    374 deaths were attributed to the heatwave.
    Total Australian deaths in January 2009 – 11609
    Total Australian deaths in July 2009 – 13183

    A standard Australian winter causes more deaths than even the hottest summer.
    Australia is similar to USA when it comes to retirement.
    More citizens migrate to hot states than to cold states, when the retire,
    A warmer climate is net beneficial to the health of Australians

    • How many hot deaths are due to electricity being to expensive for retires and the poor to run AC? I live in Arizona and am retired, in my presently cost of electricity for me is not a problem nor will it ever be. But cross over to the state line west of me it is a problem for a great may people. California electric rates are three time what I pay.

  11. The usual half-truths and distortions.
    For instance:
    “… There has been a decrease in streamflow at the majority of streamflow gauges across southern Australia since 1975 …”.
    The decade 1970 – 1980 was an unusually wet period across Southern Australia particularly the SE where most of the streams are.
    And the trend doesn’t bear much relationship to the CO2 trend, if that is the supposed inference.
    http://www.bom.gov.au/tmp/cc/rain.seaus.0112.37190.png
    Similarly:
    “… In the southeast of Australia there has been a decline of around 12 per cent in April to October [cooler seasons] rainfall since the late 1990s …”.
    But there has been an increase during the warmer seasons resulting in no overall trend since 1900.
    http://www.bom.gov.au/tmp/cc/rain.seaus.0112.3863.png
    In my opinion replacing legacy thermal electricity generating plant with more wind and solar farms in Australia will gradually impoverish most citizens while making bu99er-all difference to the future climate.

  12. “….more time in drought, yet more intense, short duration heavy rainfall events.”
    Virtually every government agency has been spouting this BS for more than 10 years.
    It is a total BS alarmist statement with no valid evidence.
    It only designed to scare.

  13. Life has NEVER been better for humanity, but think if took the money wasted on “green” ideology and made life even better…

  14. One might argue that the people in the 1800s were hardier than the city dwellers of today who have become used to air conditioning in their cars and buildings.

  15. There is a photograph ‘123 degrees’ at my hometown, Mildura in 1906, and the Mildura record has been extensively adjusted and then readjusted and the location of the recording site moved and then the thermometer converted to electronic, with a period of overlap – that is difficult to access raw data from :

  16. CSIRO need to take a long hard look at the Nino34 region and ask why it has been steady for the last 40 years. This region is considered a key to forecasting major weather events in Australia.

    Tropical cyclones are one of the major temperature control mechanism. The fact that there is no increase in intensity or frequency is a clear indication that there is no warming.

    The only source of warming in Australia is data fiddles; or its technical term – data homogenisation. Without that there is no warming.

  17. Oz Liberal politicians should hang their heads in shame at this D grade report.
    Oh – did I forget to say I mean the Quality of this report not the state of climate that it tries to paint.
    The research and analysis is so poor that it, surely, could not achieve any proper academic score.

    Take a close look at the list of references.
    I went straight to the “Marine heatwaves and coral reefs” section to see who CSIRO think know what they are talking about. Not a single dissenting view in the list … why am I not surprised?
    This echo-chamber of “authorities” even includes a short (400 word?) puff-piece in Their Conversation by Terry Hughes and Morgan Pratchett (JCU “BS-professors”) with no data and really subjective data gathering (eg “Two observers, from the ARC Centre of Excellence for Coral Reef Studies and the Great Barrier Reef Marine Park Authority, scored each reef visually, repeating the same procedures developed during early bleaching events.”) Is that a citable “reference”?
    Yet no reports from Peter Ridd or Jennifer Marohsay that show counter positions and need to be debated or included for balance in their analysis.
    Just really bad science. CSIRO has become the anti-science centre of Oz?

  18. I do find it so interesting that there is a peak in heat deaths during the 1930’s in australia, Exactly at the same time as all the heat records in the US that they are busily trying to erase. A global occurance?

  19. ‘As someone who lives in a warm part of Australia, I’ve got to say 1.4C warming since 1910 does not feel like the end of the world.’

    but it didn’t just gradually move up so all the temps were just 1.4 degrees… that represents and awful lot of seasonal heatwaves and 40 degree plus temperatures.

  20. Heatwaves, droughts and floods are all just relative terms and have no useful meaning when discussing large areas with different climates.

  21. LdB,

    More extremely hot days and fewer extremely cool days

    A continued decrease in cool season rainfall is likely to lead to more time in drought, yet more intense, short duration heavy rainfall events,

    On page 9 there is “Healthy Appetite for Innovation”, with the sub title “The CSIRO is pioneering a bold, strong and profitable future after COVID-19”.
    The first paragraph starts:
    “After years in drought, most grain-growing regions in Australia are about to pull in their first decent crop in a long time. For our livestock farmers the recovery will be slower as they rebuild herds and flocks. If it wasn’t for CSIRO we might be more optimistic about the bumper harvest the Australian Bureau of Agricultural and Resource Economics and
    Sciences forecasts. It foresees a 91 per cent increase in wheat production on last year and potentially the biggest crop since the record high of 2016-17. But global economic decline and decreased consumer demand due to the pandemic have lowered prices, and Australia’s export earnings are not predicted to increase. …..”
    Not a dickey bird about Climate Disasters! As the Yanks might say “Go figure”!

  23. Precipitation seems reciprocal to amount of Green electricity, according to the “Wet Season Rainfall” map in the post.

    Stop Green, it’s causing drought!

  24. The study includes hot wind gusts for several seconds at airports which weren’t used back in 1910. Cut by 50% and it’s in the ballpark.

  25. Since Aussie politicians are so fond of telling us that Carbon Dioxide causes Global Warming/Climate Change, when are they going to stop exporting Millions of Tons of Carbon every year (Coal, Petroleum, and Natural Gas) to China where that Carbon is burned and produces Carbon Dioxide? Or will those politicians continue to hide their cognitive dissonance and hypocrisy behind a screen of virtue signalling?

    • Maybe we should let The Greens “win” and totally stop exports of thermal coal and natural gas. Then our usage will be relatively insignificant vs the amount no longer consumed overseas.

      May as well stop exports of metallurgical coal as well since The Greens can’t distinguish between the different types. And The Greens can also provide detailed plans for all the green, renewable jobs for the displaced mining workers- fully costed, of course.

    • Shhhh we might smoke dope but we don’t inhale silly.

      On that note our dwindling oil refineries have like coal fired power stations been running on sticky tape and string to eke the last of the revenue out of them. To that end and no Gummint wanting to lower the boom on them we still have Euro5 vehicle emissions standards running 91 octane petrol with higher sulphur content because there’s no economic case for upgrading them to cleaner 95 and 98 RON. Introduce higher fuel standard and they’d all close but Covid has brought forward the crunch time for them suddenly and decisions decisions as to whether Federal and State Gummints of different persuasions will kick their can down the road-

      Only the impotent are pure in politics particularly at a time of high unemployment and cash splashes with Covid for all sorts of hungry mouths.

  26. From the article: “There is substantial evidence Australia experienced warm spells in the 1800s comparable to today.”

    We don’t have to go back to the 1800’s to show it was just as warm in the recent past as it is today.

    Australia Tmax temperature chart:

    https://bobtisdale.files.wordpress.com/2018/12/Figure-12-2.png

    As you can see from the chart, it was just as warm in the Early Twentieth Century (ETC) in Australia as it is today, so claiming Australia’s temperatures have increased since the ETC is just wrong. Provably wrong. The proof is right in front of everyone’s eyes.

    Funny how lots of people seem to ignore this aspect of the temperature record. And I don’t mean alarmists. I expect them to ignore the written temperature records because they invalidate the Human-caused Climate Change claims, so naturally they are going to ignore them and downplay them.

    What I don’t understand is why more skeptics don’t start pointing at the written temperature record as evidence that CO2 is an insignificant player in the Earth’s atmosphere.

    Since it was just as warm in the ETC as it is today, and yet there is much more CO2 in the atmoshere today than in the ETC, this has to mean that CO2 is a minor player in the Earth’s atmosphere. Much more CO2 in today’s atmosphere, but it’s no warmer now than in the ETC, equals CO2 not being a big factor in Earth’s temperatures.

    It seems too many people on both sides have been hypnotized by the Bogus, Bastardized Modern-era Hockey Stick Global Surface Temperature chart, which changes the temperature profile from a cyclical pattern (warm, cold, warm again), which is shown by regional temperature charts from all over the world, into a “hotter and hotter” pattern, which is unique and does not represent the real global surface temperature.

    No regional surface temperature chart resembles the bogus, bastardized Modern-era Hockey Stick chart. The Hockey Stick is all by itself. It is computer-generated, greed-generated, science fiction used to promote the science fiction of Human-caused Climate Change.

    Here’s a comparison of the US surface temperature chart (the REAL temperature profile of the Earth) on the left, and the bogus, bastardized Hockey Stick on the right.

    http://www.giss.nasa.gov/research/briefs/hansen_07/

    All unmodified regional surface temperature charts look like the US surface temperature chart which shows it was just as warm in the ETC as it is today. That’s why I say the US surface temperaute chart represents the real temperature profile of Earth. The real temperature profile of the Earth shows us we have nothing to worry about from CO2.

    No unmodified regional surface temperature chart resembles the bogus Hockey Stick chart. That ought to tell you that the Hockey Stick chart does not represent reality in any way, shape or form.

    The written temperature record is reality. The computer-generated Hockey Stick record is science fiction. Reality says we don’t have to worry about CO2. Science Fiction says, “It’s worse that we thought!”

    • ” it was just as warm in the Early Twentieth Century (ETC) in Australia as it is today, so claiming Australia’s temperatures have increased since the ETC is just wrong. Provably wrong. The proof is right in front of everyone’s eyes..”

      No it isn’t. Bob’s graph ends in 2012, excluding the warmest years. Even without them, the trend line on his graph looks to be climbing.

      The missing 8 warmest years. “Funny how lots of people seem to ignore this aspect of the temperature record.” Mmm.

      • You mean excluding the years just after the end of the strongest period of solar cycles in many hundreds of years.

        The warming caused by a large El Nino event.? That warming ??

        An event that had NOTHING to do with any human causation whatsoever. ??

        Only warming in the satellite era has come at El Nino events

        UAH Australia show 2020 year to date as being below 1998 and 2013, about equal to 2002, 2005

        ….. so your comment is YET AGAIN, based on ignorance.

        Would you like to try to provide some evidence for your continued propaganda parrot droppings?

        1… Do you have any empirical scientific evidence for warming by atmospheric CO2?

        2… In what ways has the global climate changed in the last 50 years , that can be scientifically proven to be of human causation?

      • “The missing 8 warmest years”

        Only in BOM’s much adjusted and UHI affected fabrication.

        Where past data has been stored in the freezer.

        …. or in the case of pre-1910 data… given to the dog to bury in the back yard.

      • “The missing 8 warmest years. “Funny how lots of people seem to ignore this aspect of the temperature record.” Mmm.”

        Well, you see, Loydo, Austrailia has its own homegrown Data Manipulators in the form of the BOM, and like their counterparts in other parts of the world, they bastardize the temperature records for political purposes.

        Here’s an example of how the Data Manipulators have manipulated the US surface temperature record. The first link is the actual tempratures before the data is manipulated, and shows that it was warmer in the 1930’s than it is today. The second chart is the bastardized one where the Data Manipulators have changed a cyclical temperature profile into a “hotter and hotter” temperature profile that conforms with their Human-caused Climate Change Hoax.

        Austrailia’s Data Manipulators have done the same thing to Austrailia’s surface temperature chart.

        US Tmax Raw chart compared to bastardized Tmax:

        https://realclimatescience.com/wp-content/uploads/2019/09/USHCN-RAW-TMAX-Vs-Year-1895-2019-At-All-US-Historical-Climatology-Network-Stations-Red-Line-Is-5-Year-Mean-USHCN-RAW-TMAX-vs-Year.png

        https://realclimatescience.com/wp-content/uploads/2019/09/USHCN-FINAL-TMAX-Vs-Year-1895-2019-At-All-US-Historical-Climatology-Network-Stations-Red-Line-Is-5-Year-Mean-USHCN-FINAL-TMAX-vs-Year.png.

        None of the internal US regional surface temperature charts resemble the “hotter and hotter” temperature profile. They all show cyclical movement and they show that the Early Twentieth Century was just as warm as today. I bet Australia’s internal unmodified regional surface temperature charts don’t show a “hotter and hotter” profile either.

        Show me an unmodified Austrailian regional temperature chart with a “hotter and hotter” temperature profile.

  27. History shows civilisations collapse from over burdening their surrounding land.

    Australia is 7.692 million km2.

    Australia has removed 40% forest / woodlands in 200 years predominately east coast, mostly last 50 years.
    https://www.serca.org.au/research/2012/Bradshaw.pdf

    “Desertification in some form is estimated to have occurred over about 42% of the 5 million km2 of arid and semiarid lands in Australia.”
    Ludwig, J.A., Tongway, D.J. Desertification in Australia: An eye to grass roots and landscapes. Environ Monit Assess 37, 231–237 (1995). https://doi.org/10.1007/BF00546891

    Broadscale deforestation / grass woodland removal has huge impact on regional and localised rainfall and temperatures. The changes seen in Australia coincide with land use change acceleration, ie past 50 years or so.

    Why is this not part of the conversation from either side?

  28. Breaking news……

    “Perth has recorded its wettest November on record — and we’re only halfway through.

    As of 5pm today, heavy showers had dumped 76mm of rainfall in the first two weeks of the month.

    The downpour has trumped the 1984 November rainfall record of 73.2mm.

    More than three times the November rainfall average of 23mm has been recorded so far, and four times the 2019 November average of 18.4mm.

    Perth has also recorded its coldest start to November in eight years, with three days where the temperature didn’t get above 19C.”

  29. The problem with the BoM’s State of the Climate claim of increasing extreme heat events and annual hot days (see http://www.bom.gov.au/cgi-bin/climate/change/extremes/timeseries.cgi?graph=HD35&ave_yr=0) since 1910 is that they’re based on homogenised ACORN rather than original RAW temperature observations.

    ACORN reduces the number of 35.0C+ hot days in the first half of the 1900s as it does the average temperatures.

    A comparison of hot days in RAW and ACORN can be viewed at http://www.waclimate.net/very-hot-days.html

    I’ve added a couple of graphics today plus some text, including …

    Two examples are Boulia in Queensland and Marble Bar in Western Australia, which provide many of the hot and very hot days within the total for all 112 ACORN weather stations. In 1910-1963, the 60 ACORN stations with maximum observations available since 1910 had 131,519 days above 35.0C in original RAW, and 115,202 in homogenised ACORN (-12.4%). Among these, 21,500 were at Boulia and Marble Bar in RAW (16.4% of Australian total), and 13,587 in ACORN (11.8% of Australian total).

    • Throw into this mix:
      1. Relocation of stations from Post Offices to regional Airports.
      2. Increasing size of aircraft using regional airports.
      3. Replacing LIG thermometers with faster response electronic temperature gauges.

      All contribute to measured temperature rise.

      Warming is all rubbish. If there is a recorded temperature change as a long term trend, look for the inconsistencies in the actual measurement system rather than them being an accurate representation.

      The temperature of tropical ocean cannot increase; cloud coverer over tropical oceans increases asymptotically as SST approaches 32C. The sun never shines on the surface below under these conditions. It is impossible for the SST in open water to exceed 32C. The only place on Earth where SST exceeds 32C is the Persian Gulf. The hot, dry desert winds prevent dense cloud formation despite very high rates of evaporation at ground level as well as high humidity in the near surface layer. But very low cloud cover and only sub-tropical sea surface above 27C that has not experienced cyclone.

  30. So the CSIRO puts out a report to support itself. That’s actually what’s going on here.

    It’s quite plain to see….

    Quote from the report…..

    “Our role at CSIRO is to accelerate this decarbonisation of electricity, industry and transport sectors by delivering transformational science, technologies and solutions”.

    You see? That is their ”role”. Therefore, would you expect anything but the third rate garbage they have submitted?
    FOLLOW THE MONEY.

    Conflict of interest much??

  32. Well, congratulations to CSIRO (and BOM) for getting it up!
    We all know that a lot of hard work and effort went into this.
    Remember, climate statistics don’t just happen.
