The Last Warning CO2, Peak Oil, Overpopulation Planning for Survival [Sequel: The Climate Change Controversy] |

The universe is said to have started 13.7 billion years ago with a big bang, however the generally accepted theory is disputed on several grounds. The Hubbard deep field telescope has pictures that are 2 billion years short of the event, a remarkable achievement, but it is unlikely to get any closer. When it comes to the stars we are on much surer ground, we know more about stars than we know about life at the bottom of the ocean, due to the examination of light they emit and knowledge of atomic interactions. From this we are able to work out their distance, their weight, their composition and speed of recession, even their life. Astronomers have a good deal of fun telling us that we are made of stardust. There are said to be 3 generations of stars. The first generation, known as population 3, consisting only of hydrogen and helium, had a short life and if they were heavy enough they finished by exploding, creating the heavier elements as dust which condensed to form the second generation. The current generation (population 1) now had all the elements including carbon, oxygen, nitrogen etc. necessary for life to form, thus stars had to evolve and explode before life was possible. Our sun was born some 5 billion years ago and the earth came a little later at about 4.5 billion years ago. Being hot, with many active volcanoes, the atmosphere was mainly CO2 that kept the planet warm, important because the young sun was 25% cooler than it is now. The first life to develop was a microbe, very different to us as it lived in CO2 and regarded oxygen as a poison. It is important to realize that CO2 is a greenhouse gas, that is, it allows sunlight to pass through it and hit the earth. 30% is reflected and would leave the earth, but as reflected light is at a lower frequency (infra red) where CO2 is no longer translucent, the gas warms up, retaining the heat on earth. We must also realize that some CO2 is needed, it is the carbon component which builds all trees and plant life. There was no free oxygen in the early atmosphere and it was not until 1.5 billion years ago that photosynthesis produced oxygen using cyanobacteria and later from plants. For another billion years the oxygen reacted with rocks as recorded in Banded Iron Formations. It wasn’t until 0.6 billion years ago that there was sufficient oxygen to form the ozone layer allowing animals and plants to spread across the land. Numerous fossils tell the history of the resulting development right up to Homo Sapiens in the most recent two million years. This development was interrupted by five extinction events, the big one took place about 251 million years ago. 95% of all animal and plant life was exterminated. New life forms developed. It took 100,000 years for life to recover. The most recent event was 65 million years ago. The dinosaurs were wiped out, mammals took their place. Well might we ask, "How the bloody hell did we get here?" It does seem to be a sporadic, chancy affair, not repeated anywhere else in the universe that we know of.
In June 1999 the Ice Core data from Vostok, Antarctica was published. The core was 2.2 miles long and represents a huge achievement. Only a small amount of rain falls each year but is sufficient to trap tiny bubbles of air and dust which are analyzed with the results shown in graph (1). |

THE SEQUEL: The Climate Change ControversyBeing the editorial written for the South Australian Humanist Post, March 2007It is of course election year and this year our politicians will be trying to convince us that their method of combatting climate change is the only reasonable one, all others should be rejected. So, I write this with the object of clearing up several of the many misconceptions held on this subject. Firstly, what has this to do with Humanism anyway? I will answer, everything, we often point out that this is the only life we have and therefore we had better make sure it is a good one. Likewise this is the only earth we have, other planets are a long way away and very inhospitable, so we had better look after the one we have. Religious people are often confused when they try to answer the same question. Some remember the doctrine of Stewardship but often don’t connect it with pollution. Others say God will look after us but don’t like the comment "God only takes care of those who look after themselves." There are those who say "look the weather is lovely, sure there is a drought but no worse than we have had in previous years, surely what you say is greatly exaggerated?" To answer this I would start with the story of Dr Suzuki’s petri dish. A Petri dish is a glass dish about the size of a saucer. You fill it with water and nutrient. A microbe or germ culture is placed in it and if the temperature is right it proceeds to grow. The way it grows is of great interest to scientists. At five minutes to midnight one microbe is heard saying to another, "All this talk about us being overpopulated is ridiculous, look there is plenty of space" Midnight strikes, and the petri dish becomes a stinking, lifeless, mess. The biologist will tell you that this always happens unless the dish is cleaned up first. The Earth is one, big, in-side-out petri dish with a very thin film of water and gas as any astronaut will tell you. Even he is entirely dependent on that small part of it he took with him. It is not difficult to alter the atmosphere by amounts that can be catastrophic for most life forms. The readings of CO2 at the Mauna Loa observatory in the Pacific show the forests drawing down the CO2 in summer but in winter it cannot cope with the double whammy of the natural emissions plus our industrial and domestic output of CO2. The current levels peak at about 386 ppm where as from 600,000 years ago to about 200 years ago the trees kept the CO2 down to a level never exceeding 280 ppm. The temperature moves in step with the greenhouse gasses and scientists predict with the help of computer models that another 2°C and the climate will "tip" to a situation which is hotter, catastrophic to agriculture, and will never restore itself. The solution is to build atomic power stations. There are countries without solar, wind and geothermal sources. Such countries should use atomic power in lieu of coal and oil. In Australia we do not need to do this. Those who argue for atomic power are thinking about water cooled reactors which are inefficient and expensive. The world has about 440 of them working at present. If the world were to double that, the energy capacity would only go up by a few per cent but the high grade ore would be used up within 10 years and poorer ores would need more energy to process. Other types of reactors are still experimental. The high cost of developing an atomic reactor will take resources away from other greenhouse projects. We need to develop all types, including Geothermal, various forms of solar and wind power and all new inventions. Alternative energy is more costly and does not provide a base load. Coal and oil have been very cheap, but we will pay far more if we don’t make corrections immediately. Geothermal energy will provide the base load in Australia for the next 100 years. The project at Paralana alone will be capable of providing 8 times South Australia’s present consumption. Salt Power Towers are being built o/seas capable of 10 megawatts, the heat in the salt lasts many hours so power is produced day and night. Solar cells are costly but have the advantage that they can be put on almost any roof so power is produced locally. While they feed the grid they reduce our dependence on the grid. Real subsidies should be provided. NEW! Green and Gold Sun Cube commencing production in South Australia. 600Kwh/year for AU$1,365.00 fixing extra. So cheap subsidies not required! <http://www.greenandgoldenergy.com.au> Sequestration will solve the problem of coal fired
generators. The ground in many places in Australia is unsuitable
for sequestration. The huge volume of waste to be placed underground may
make it a very temporary solution. The time it will take to make
sequestration work is excessive. Owners and shareholders of coal fired
generators should consider that the following policy might not produce
higher profits than sequestration: Coal and Oil used in Australia is only a small amount of world consumption. We must use oil and coal in order to compete. Per Capita, Australia is the highest user of oil and coal, it is therefore up to us to set an example to the rest of the world, manufacture and export greenhouse systems. We have to stop using oil and coal in order to survive. There is plenty of Oil , it will take 35 years before we reach Peak Oil. Those who believe in large quantities of oil being available do so because they take into account the large quantities locked up in shales and sands in North America. Only recently have they found a solution by applying heat using gas. To burn the gas, then burn the resulting oil sounds like a double dose of CO2 production, but they have built factories in Canada where they have caused serious pollution to Canadian Rivers and the USA has indicated that they would prefer the gas. We are still in the position that Peak Oil is here and now, and that oil production will be 32% down by 2020 forcing us to use alternative transport which includes upgrading rail and tram, extending disused tracks, manufacturing electric cars, (also miniCAT cars which run on compressed air but need an electric pump). V8's and similar cars to be banned in 5 years time. Electric cars do not have the range and power to drive in Australian conditions. They will be smaller, lighter and will carry less people. But some models will drive fast if so designed. Petrol stations will become recharging stations where you can swap your discharged battery for a fully charged battery and continue on your way. The overall cost per kilometre will be much less. They will be more suitable for driving in metropolitan conditions where most of our driving is done anyway. Carbon tax should be applied to all fossil fuels on a world wide basis. This would make the renewables more cost effective, however this and Kyoto policies are palliatives to industry and don’t solve all problems. A carbon tax is giving a licence to someone to pollute, it encourages a "business as usual" attitude, not recognising the need for reform. We need to keep the main objective in view, the provision of clean energy sources and green transport. Because of the large amount of infrastructure required we shall need some coal and oil, any taxes would only be passed back to us making it more difficult to afford the infrastructure. All industries are expected to covert to green energy so that dependence on coal and oil should reduce to a low level in the first 5 year plan. Coal and oil provide a large amount of employment. At the cost of the demise of civilisation. The new infrastructure will provide lots of employment, its maintenance will provide more. Education will be needed to cope with the new technology, TAFE will have to be upgraded, we should not rely on importing labour, especially from third world countries. Financial problems: The increasing price of oil will make the use of petrol guzzlers uneconomic and cause hardship to those still paying them off. The need to build infrastructure as soon as physically possible will require the provision of capital preferably at nil rate of interest. It is essential to build new infrastructure within the next 15 years as it may be too expensive thereafter. These matters should be discussed with financial experts and plans prepared now. Concentrating solar thermal technologies CST involves concentrating the sun’s rays to produce heat generating electricity directly or to heat a fluid to operate a turbine. It is a proven technology with nine existing plants feeding the Californian Grid. Mr. Peter Andren, independent MP for Calare has sent me a report issued by CRC for Coal in sustainable development. He says: The report confirms that solar thermal technology can supply Australia’s base load energy needs and could be price competitive with coal supplied energy within 5 years if built to a large scale. This report had been shelved by the government but was leaked to the Canberra Times last year and is now on the WWW. The report gives details of five high temperature systems, three of which are commercially available. It is possible to store some of the heated fluid which can be used 6 - 13 or more hours later when there is no sun. Australia has a lot of sun, all that is needed is a large vacant area to take the solar collectors, situated away from coastal areas. The engineering details are well known, there are no adverse impacts, environmentally or socially. Why should the CRC for Coal in Sustainable Development produce such a report? A good question, but part of the report is concerned with the possibility of having a hybridised system which would have economies, as the same turbine generator system can be used. There would be similar economies in a hybridised CST and Geothermal system The great advantages of these systems is that they have a large capacity, can be built far faster than most systems, can be exported to most places in the world and are the greenest of all systems. There is positively no excuse, Australia should build several such plants without delay. Please remember that the many innovative reforms advocated here are recommended not only because of climate change but also because of Peak Oil and Overpopulation. If one problem does not eventuate, the others will! DC. |
