71% of the earth’s surface is covered by water and large areas of the land are covered by frozen water. Water and water vapour are also significant components of the atmosphere.
The atmosphere and its trace component of carbon dioxide is a very thin skin in close contact with the surface of all of this water. Carbon dioxide is very soluble in water and Henry’s Law says that as the temperature of water changes the quantity of carbon dioxide dissolved in that water will change.
Thus if the sea surface temperature increases, carbon dioxide will be expelled to the atmosphere just like carbon dioxide bubbles are expelled from a warming beer. And as sea surface temperature falls, carbon dioxide will dissolve in the cooling water and this reduces the carbon dioxide in the atmosphere.

The Federal Gallery journal has published this article by Dr Brady in its March 2020 edition. Dr Brady says that “politicians on both sides of the climate debate are making statements that are actually false. In good faith they think that certain propositions are correct”, so he needs to show otherwise.

If you want to witness cases of scientific illiteracy, selfishness and hypocrisy, look no further than the attitudes, actions and comments from a number of banking personnel. When it comes to uninformed opinions about climate change and the lack of concern about delivering affordable energy to the poor in developing countries, some of them appear to have no equal.
Judge for yourself. Continue reading “Do these Bankers Really Care about the Poor?”

Despite alarmist claims of “catastrophic global warming”, there is no empirical evidence to confirm that or any acceleration in global sea level rise. Notwithstanding this lack of evidence many people, often those with vested interests, still cling to the alarmist beliefs that catastrophic sea level rise is imminent.
If you live on an overpopulated island with high unemployment, limited resources and were already dependent on aid from the outside world, there is one sure-fire strategy for bringing in extra money. This involves ignoring the lack of empirical evidence for any acceleration in global sea level rise or increase in extreme weather whilst taking the following steps: Continue reading “Sea Level Alarm – a Nice Little Earner”

In reality there is no such thing as a universal measure of sea level because there is no fixed datum against which measured levels can be compared. Similarly, the term “Global Average Sea Level” is simply meaningless and claims that sea level is rising at an unprecedented rate worldwide are questionable, if not deliberately alarmist.
The average depth of the world’s oceans is around 4,000 metres and for anyone to claim they know that global sea level has changed by 2 or 3 cm over the last few years requires pure imagination, especially in light of the many factors that influence relative sea level.
The array of factors that influence sea level measurements at any particular time and place include: Continue reading “MEASURING SEA LEVEL”

The seas and oceans to the east of Australia forms the largest body of water on Earth. This broadly connected vast body of water presents a genuine sea level. The Sydney Fort Denison Recording Station provides stable, accurate and genuine mean sea level data. The following table shows mean sea levels at 10 year intervals and these levels are related to Chart Datum which is at the lowest spring tide level.

I am a retired Surveyor who spent his whole career (1965 to 2010) measuring and recording:
- Water depths, to enable safe navigation of ships and boats into harbours.
- Coastal features, such as shorelines and beaches, to monitor changes in depth that occur over time.
- Near shore constructions, such as sea walls, groynes wharves, piers and jetties and boat ramps to monitor their effect on the surrounding areas.
In order for these depth measurements to have any coherence they have to be related to a common reference level. In Australia this common reference level or Datum is the Australian Height Datum (AHD).
AHD is a mean sea level datum and was established by analysis of data from recording tide gauges which operate in ports around Australia and which in some cases have been operating for around a century. (see below) I have not found any proposal that this datum be changed due to the rising sea level.

For decades now the IPCC and other alarmists have been threatening us with the ugly spectre of hugely accelerated sea level rise (SLR). Fortunately, none of their dire predictions have come to pass yet this has not caused them take a look at just how ludicrous their predictions really are.
During this time, sea level has continued to putter along just as it has for the past 150 years, at a minuscule rate of about 1-1.5mm/year. This is a very tiny amount of SLR, not even noticeable by the average human. In fact, a person living on the coast of almost any country for 80 years would not notice any change in sea level, from childhood through retirement.
Given that the majority of people tend to live in coastal zones, it is baffling how anyone can give credence to any of the wild claims of METERS of SLR by the end of this century. A rise of 0.30m would be very obvious if it occurred in a matter of just a few years. But when it is spread out over 100 years, with the natural ebb and flow of the tides, it just looks like business as usual. Continue reading “Land and Sea Go Up and Down”

- There has been NO significant sea level rise in the harbour for the past 120 years, and what little there has been is about the height of a matchbox over a century.
- Along the northern beaches of Sydney, at Collaroy there has been no suggestion of any sea level rise there for the past 140 years. Casual observations from Bondi Beach 1875 to the present also suggest the same benign situation.
- A rush to judgement by local councils and State Governments by legislating harsh laws and building covenants along our coastlines now seems misplaced.
- The falsehoods and mendacity of the IPCC and climate alarmists should be rejected out of hand, and efforts be made to ensure that science, not propaganda, defines our school curricula in matters of climate and sea levels
