What Could Possibly Go Wrong?

The official thermometer at Sydney is located immediately adjacent to 22 lanes of asphalt, and across the street from a glass building which reflects sunlight down on to the thermometer.

The thermometer shows rapid warming over the past twenty years.

But the thermometer in Sydney Harbour shows no warming over the past 20 years.

And no change in sea level for 140 years at Sydney Harbour.

There can be little doubt we need massive taxation and loss of freedom to reverse the zero-trend lines.

    The coordinates of the Sydney Observatory are 33.8596°S 151.2047°E. It is surrounded by a park and basins of Sydney harbour. Looks like you spotted the meteo box of Fort Street Public School.

    Sydney harbour today had a difference of 0,9 m between high tide and low tide. Cheap trick to pick the “no change in sea level” pictures, but you overlooked the signs of humidity on the walls that witness a much higher sea level during high tide.

    • tonyheller says:

      That is the box at Sydney Observatory. I’ve stood next to it. The high water mark at Fort Denison hasn’t changed.

      What is the point of your baseless and misinformed comment?

    • R Shearer says:

      Plus I only count 17 lanes, not counting the 4 or 5 on the opposite side of the park.

      Poor Alex, real data is tough on you, isn’t it

      Fort Denison has a mean sea level trend via the tide gauge of 0.65mm/year.

      Recent survey studies have shown that the Fort is subsiding at a rate of about 0.4mm/year

      That gives a real sea level rise of 0.25mm/year over 100 year

      Let’s look at The Observatory Hill thermometer from above

      You can clearly see the footpath as shown in Tony’s picture

      Take another faceplant, bozo !!!

    • MatrixTransform says:


      how is it that excess ‘measured’ humidity when surrounded by water is actual evidence.

      But that excess temperature when surrounded by asphalt (and a car park of idling cars) somehow isn’t.

      do you see the image of the devil every morning when you look at your toast?

      how about the mirror?

    Sounds like a Gary Larson cartoon — Either pay up today or burn in hell tomorrow.

  3. M Bannister says:

    According to the Fort Denison tide gauge the level has increased 0.21 metres in the last 150 years – doesn’t seem a lot !

    • tonyheller says:

      Due to gravity, tide gauges get pulled downwards over time.

      • rah says:

        Of course that could be easily corrected so the measurements over time are more accurate but isn’t.

        It really is a shame. For a fraction of the money being used to pay the Ivory towers to produce their endless stream of climate and weather fiction our surface temperature station and tide gauge networks and could be brought up to date using the best available technology and expanded to provide better coverage.

    I got stuck in that spiral in mid summer once, for about 20 minutes.

    Not a pleasant experience. Heat and fume build-up was incredible.

    Observatory Hill is MASSIVELY urban heat affected

  5. John F. Hultquist says:

    The Sydney Observatory weather station was the topic of a post by Bill Johnston, on Jo Nova’s site awhile back:
    Sydney Observatory

    Historic photos are included, including the 1938-on building of the Cahill Expressway. That is the circular road the wraps around and goes into a tunnel, heading east, passing left of the tall building at the top of Tony’s first photo.

    I find the old photos as beautiful as the ones Tony takes of birds.

    Be of good cheer.

      I just realised that my complain about the wall was already mentioned in your link.

    • R Shearer says:

      Interesting. I was only able to load a couple of days of data for the station but it appeared that there was an impact in temp from rush hour traffic on one of the days. Anyone have a link to the full record with high resolution?

  6. arn says:

    One should also mention the wall right behind the thermometer that stores heat and releases at night,
    +the thermometer is very well protected,not just by the wall but also by trees.
    Only one side is open to get some cooling wind.

  7. Bruce of Newcastle says:

    I’ll add that the building is directly east of the Observatory, so it will reflect sunlight right at the peak of the daily temperature cycle in the afternoon, especially in summer when the Sun travels nearest to east-west.

    Also that pick is of the main highway from the Sydney Harbour Bridge, without much traffic. In peak hour it is absolutely packed. So the afternoon peak is going to have the hot exhausts of thousands of cars added to the ambient air temperature.

    Tmax is going to be ‘way up compared with a better site.

  8. Matthew Bruha says:

    It should also be pointed out that the Observatory temperature records are also used in the homogenisation of temperature records from stations with different weather patterns in different climate zones (ie central NSW and Snowy Mountains)

    It looks like the Aussies have adopted NOAA’s Death Valley weather station placement strategy:

    Death Valley’s “hottest month ever” was likely a product of nearby solar panels and RV’s

    I used to live in Sydney and at one time I lived at Manly, near where Governor Phillip supposedly landed at Manly Cove (a harbour beach) in January 1788 to set up the NSW colony.
    Below is 123 Years of rising sea levels due to CO2-Climate Change (sarc). Manly Cove, Sydney Harbour. Note the retaining wall still exists but the Norfolk Pine trees replaced the previous trees

  11. John of Cloverdale, Western Australia says:

    From my Global Warming-Rising Sea Level Collection of Sydney.
    About 100 years of sea level change at Rocky Point, Balmoral Beach, Sydney Harbour.
    Looking east towards the entrance of the harbour.

    Here in Holland we are facing similar types of problems . The weatherstation at Eindhoven Airport in the past was nicely located in a thermohut in an open field far away from concrete and buildings . Nowadays it is completely surrounded by buildings and concrete since the airport became a commercial hub about 10 years ago . Anyway the new data are “proving” global heating is real and in every school here in Holland youngsters are indoctrinated with this garbage-science . There are a few in Katowice now afraid to dy in the coming years suffocated by carbondioxide and overheated beyond boiling by other greenhouse gases . They intend to sacrifice the poor in our world in order to punish the rich . How foolish can you become . programmed ?

  13. Lasse says:

    Sidney Harbour: 50 Years mean changes shows a clear periodical change in sea levels:

    And a rate of 0,65 mm/year
    That is 0,065 m in 100 Year.
    And how much was the daily change?

    • R Shearer says:


      The beach is a little more crowded today and high rises all around these historic hotels, can’t see any evidence of significant sea level rise from photos, however.

      • dp says:

        The old sea walls are exactly where they used to be. Hansen’s hysterics would have us imagining visitors fishing from the second-story windows.

        On the opposite side of the island Popoi`a Island (Flat Island) is still flat. It was formed as a reef when sea level was much higher than it is today. Given the subsidence rate of the island chain that is quite an accomplishment for a time when there were no SUV’s to drive the climate.
