I’m back in Yeppoon. This afternoon I was at Wreck Point, and in the distance, over my left shoulder, you can see Great Keppel Island. According to the New York Times there is mass coral bleaching there (CLICK HERE). A photograph of the corals at Monkey Beach reef featured in an article in that newspaper just yesterday. It was apparently taken on March 5, 2024.
(I’m hoping to see these corals for myself this weekend. To be sure to know what I find out, to be sure to see the photographs I’m hoping to take, consider subscribing for my free email updates (CLICK HERE).)
The New York Times attributes the bleaching to extraordinarily warm ocean temperatures. Of course, there is no chart, no data – no information on actual ocean temperatures.
It is exceedingly rare for any newspaper to ever publish location specific temperature data. In fact, that is the only real type of temperature data: location specific data. Everything else is a construct – a contrived statistic.
The picture of the bleached corals at Great Keppel Island, published in the New York Times, was apparently provided by AIMS (Australian Institute of Marine Sciences). Of course, they also have temperature data. One of their key weather stations is at Square Rocks just to the northwest of Great Keppel Island. There is data for the period December 19, 2009, through to February 19, 2024. This data, consistent with the information I have previously published for the central region does not suggest that ocean temperatures have been particularly warm this last summer.
(There is very little difference in the two temperature profiles at the different depths so there is much overlap in the above chart. For clarity I will also now post these times series separately.
There is sea level data for Rosslyn Bay, just across a little further to the east from Great Keppel Island. (I will be catching the ferry to Great Keppel Island from Rosslyn Bay marina at the end of the week, weather permitting and passing Square Rock.)
This sea level data indicates monthly averages are towards the low end of their annual cycle, and have stalled. This is consistent with an El Nino event and the water sloshing over to the other side of the Pacific Ocean, you can read more about the phenomenon at the NOAA website (CLICK HERE).
Could it be that the bleaching at Great Keppel Island has more to do with lower-than-average sea levels for this time of year, rather than unusually warm water? I’m just asking the question. (It is perhaps better to have questions that cannot be answered, rather than answers that cannot be questioned.)
Square Rock also has air temperature data, and, of course, the two move somewhat in unison except that the air is consistently a little cooler. This is the air that has all the greenhouse gases, that is meant to be warming the ocean.
Of course, only someone who believes the nonsense from the experts and who can’t read a chart could believe that the air warms the ocean!
The sun warms the ocean that warms the atmosphere. That is what happens in the tropics at least, which is where I live.
MORE INFORMATION. UPDATE 17TH APRIL 2024
I’ve looked around for more information, and found water temperature data for Rosslyn Bay, that is just across from Great Keppel Island. This time series that is collected by the Australian Baseline Sea Level Monitoring Project is twice as long, beginning in 1991, and complete for this last summer.
Consistent with the AIMS data for Square Rocks, it does NOT suggest that this last summer has been particularly warm. It shows a distinct seasonal trend; it does not show global warming.
