Climate

 

I originally wrote the paper, Issues Arising from the Greenhouse Hypothesis, in 1990 and do not see a need to revise it substantially.  Some of the science is better defined and there have been some minor changes in some of the projections; but otherwise little has changed.

In the Introduction to the 2006 update to that paper I wrote:

Climate change has wide ranging implications...  ranging from its impacts on agriculture (through drought, floods, water availability, land degradation and carbon credits) mining (by limiting markets for coal and minerals processing) manufacturing and transport (through energy costs) to property damage resulting from storms.

The issues are complex, ranging from disputes about the impact of human activities on global warming, to arguments about what should be done and the consequences of the various actions proposed.

To the conclusion I added:

Australian impact on global climate is insignificant. Our main contribution is likely to be indirect by way of diplomatic efforts to change global behaviour or through research into solutions that can be applied globally. Climate is likely to change no matter what we do. In Australia we are all too familiar with the effects of natural climate fluctuations. 

The degree to which human activity changes climate is related to our level of resource utilisation.  Although energy consumption is very important in this equation so too are mineral extraction and processing, farming and land clearing, pollution of oceans and lakes and the shear number of humans and their consequent demands for food and shelter.  Not only does excessive population lead to stresses on the biosphere of the planet; it makes huge numbers of people highly vulnerable to relatively minor changes in that biosphere.

Sudden climate change is just one of a number of a range of potential catastrophes that might befall the planet. It is important that while doing all possible to mitigate the impacts of increasing resource exploitation we:

1      commit more resources to means to respond flexibly to climate change than to trying to prevent it and;

2      treat the disease (over-population) not just the symptoms (like greenhouse gasses).

We need to focus on the possible. An appropriate response is to ensure that resource and transport efficiency is optimised and energy waste is reduced. 

Another is to explore less polluting energy sources. This needs to be explored more critically.  Each so-called green power option should be carefully analysed for whole of life energy and greenhouse gas production against the benchmark of present technology before going beyond the demonstration or experimental stage.

Much more important are the cultural and technological changes needed to minimise World overpopulation. We desperately need to remove the socio-economic drivers to larger families, young motherhood and excessive personal consumption (from resource inefficiencies to long journeys to work). 

Climate change may be inevitable. We should be working to climate "harden" the production of food, ensure that public infrastructure (roads, bridges, dams, hospitals, utilities and so) on are designed to accommodate change and that the places people live are not excessively vulnerable to drought, flood or storm.

Only by solving these problems will we have any hope of finding solutions to the other pressures human expansion is imposing on the planet.

The world still predominantly depends on coal and oil for energy as outlined in Energy and a ‘good life’ and A Crude Awakening – Critique on this website.

I have summarised much of this discussion in the Environment chapter within the Meaning of Life essay, also on this website.

Recent extreme weather events appear to confirm the predictions made in my earlier paper.  As the energy of the system increases, so this energy is partly dissipated in more violent weather excursions.  This upward trend in the severity of weather excursions from the norm, as well as the shift in the norm itself, can be expected to continue.

I am still inclined to believe that human overpopulation will soon have further serious consequences for the climate, in addition to other environmental devastation, and I continue to believe that there are grounds for alarm.

In practical terms the resulting climate impacts may mean that different crops or crop varieties and grazing patterns will be required across arable regions and crop yields may be increasingly affected by extreme events; floods; droughts; fire and so on.  Correspondingly some urban and outer urban areas, for example those particularly prone to flooding; fire; or high wind, may need to be relocated.  In other areas significant new infrastructure may be necessary to guard against climate related disaster.

And the real and underlying problem, of runaway population, is no nearer to being addressed.

But politically the World is quite different.  When I originally wrote the paper on climate change scientists were alarmed but very few politicians had any opinion on the matter.  Now it is 'bread and butter'.

Travel

Turkey

 

 

 

 

In August 2019 we returned to Turkey, after fourteen years, for a more encompassing holiday in the part that's variously called Western Asia or the Middle East.  There were iconic tourist places we had not seen so with a combination of flights and a rental car we hopped about the map in this very large country. 

We began, as one does, in Istanbul.

The Greatest Aviation Mystery of All Time

 

 

The search for Malaysia Airlines Flight 370 was finally called off in the first week of June 2018.

The flight's disappearance on the morning of 8 March 2014 has been described as the greatest aviation mystery of all time, surpassing the disappearance of Amelia Earhart in 1937.  Whether or no it now holds that record, the fruitless four year search for the missing plane is certainly the most costly in aviation history and MH370 has already spawned more conspiracy theories than the assassination of JFK; the disappearance of Australian PM Harold Holt; and the death of the former Princess Diana of Wales; combined.

The Origin of Life - according to God

 

 

 

Back in April 2013 I had another visit from our neighbourhood Jehovah's Witnesses,  a pretty young woman and her husband, recently married.   Like Daniel (mentioned elsewhere on this website) before them, they had brought copies of The Watchtower and Awake; which I agreed to read if they were prepared to read my paper: The Prospect of Eternal Life.

I keep a couple of copies of The Prospect of Eternal Life for just such occasions and have also given a copy to the local Anglican minister and to various other active proselytisers in the area; with similar conditions.  Of course I know it will not change their position but I do like to have the debate and amazingly so do they; it beats the usual reception they get; and they get some practice in trying to convert un-believers. 

When the couple asked my position I quickly summarised that in The Prospect of Eternal Life
