Climate change has taken place for thousands of millions of years. The extraordinary claim that humans cause climate change must be supported by extraordinary evidence.
It has not been shown that any measured modern climate change is different from past climate changes. In the past, climate has changed due to numerous processes and these are still driving climate change. Past global warmings have not been driven by an increase in atmospheric carbon dioxide (CO2) and, during the time that humans have been on Earth, there has been no correlation between temperature change and human emissions of carbon dioxide. Without correlation there can be no causation.
The underpinning assumption is that human emissions of CO2 drive global warming and, in order to arrest the warming trend, human emissions must be cut.
Emissions of CO2 from human activities such as production of energy, metals and cement; land, air and sea transport; and heating and cooling account for about 3 per cent of total annual emissions. Despite very generous research funding from the public purse, it has yet to be shown that the human emissions of CO2 actually drive global warming.
If it could be shown that the human emissions of CO2 drive global warming, then it would also have to be shown that the natural emissions of CO2, 97 per cent of total annual emissions, do not drive global warming. This has not been done.
Natural emissions are mainly from oceanic degassing and mantle degassing via millions of submarine volcanoes, mid ocean ridge volcanicity and ocean floor fractures, with less voluminous emissions from mantle degassing via terrestrial volcanoes, mountain degassing, fractures, earthquakes and respiration.
In past times, when the earth’s atmosphere had hundreds of times the current CO2 level, there was no runaway greenhouse effect, no irreversible warming and no climate catastrophe. In fact, there were ice ages. The erroneous assumption that the dominant driving force for global warming is the emission of CO2 by humans has been made without considering the effects of the sun, tectonics, earth’s orbital oscillations, oceanic oscillations or extra-terrestrial radiation.
The oceans remove most of the CO2 from the atmosphere. What is rarely considered is that CO2 is plant food, it is rapidly removed from the atmosphere and it has an atmospheric life of about 7 years. Soils and rock weathering also quickly remove CO2 from the atmosphere. There is an underlying assumption that once humans emit a CO2 molecule, it stays in the atmosphere for a very long time or even forever. Any CO2 emitted by humans is part of the carbon cycle that involves recycling of CO2 through the atmosphere, life, water and rocks.
The human-induced global warming ideology is underpinned by the perception that the planet is static and that dynamic change only occurred once humans started to emit CO2. Nothing could be further from the truth. The Industrial Revolution in Europe and the USA triggered a great increase in human emissions of CO2 from the use of fossil fuels. This also led to increased prosperity, health, longevity and the rise of the middle class, many of whom now object to the use of coal.
The planet has been warming over the last 300 years since the Maunder Minimum and it has not been shown that any part of this general warming trend is of human origin. Furthermore, during this general warming trend, there have been both cooling and warming events.
Another Industrial Revolution is taking place in Asia, where fossil fuels are bringing people out of poverty and the rate of emissions of CO2 from burning fossil fuels has accelerated. However, there is no correlation between the emissions of CO2 by humans and temperature. In fact, the increased content of CO2 in the earth’s atmosphere has led to the greening of the planet and increased agricultural productivity. If only human emissions of CO2 drive global warming, then there should have been no warming and cooling events before the Industrial Revolution. However, pre-Industrial Revolution climate changes were fast and cooling events led to depopulation.
The arguments to support human emissions of CO2 driving global warming are based on models whereby the principal variable is CO2. Measurements and observations do not support this hypothesis. Past natural warmings have had a delayed effect on increasing atmospheric CO2. The exact opposite of the populist catastrophist mantra. If climate models are run backwards, past events of cooling and warming are not seen.
We have now had more than two decades of climate models and these models have not predicted what was measured. Without correlation of CO2 with temperature over time, there can be no causation, hence there is only one conclusion: human emissions of CO2 do not drive global warming. This shows that complicated models in a multicomponent chaotic dynamic system are an unreliable and naïve attempt to understand nature.
Models, research and energy policy are underpinned by the fallacious assumption that human emissions of CO2 drive global warming. Such ideology thrives in a dumbed-down educational environment where there is little knowledge of history and geology. Because it has not been demonstrated that there is a relationship between human emissions of CO2 and global warming, then climate policy, renewable energy targets, carbon capture, global warming research and alternative energy are unnecessary, delusional and a waste of money. New financial instruments have been created by an army of spongers to steal money from electricity consumers.
Coal-fired Australian electricity used to be the cheapest in the world. Because of the unsubstantiated belief that human emissions of CO2 drive global warming, Australian electricity is now among the most expensive in the world. Electricity in developing nations such as Ethiopia and Ecuador costs 10 per cent of South Australia, which has intentionally placed itself into sub-third world reliability and costs. Victoria has now joined the suicidal race to the bottom.
Green ideology and frightened politicians detached from reality have led to expensive and unreliable wind energy that is devastating for birds, bats, landscapes and human health. This is not environmentalism. Green ideology is based on false assumptions and unvalidated science and has led to unreliable expensive electricity and environmental devastation. Maybe environmentalism is about total control of people and de-industrialisation, rather than the environment.
