climate change


The following is based on historical scientific evidence. It is empirical science, not theoretical or predictive quasi-science. Don’t worry, I will not be analyzing gas molecular structure for its pliability, nor examining the ins and outs of El Nino nor talking about elliptical eccentricities. This is an overview of what most of us learnt in Yr. 10 science.                                                                                                                                                                                                                                                               There are 3 categories of major causes of global temperature fluctuations, [climate change]. FIRST, there are astronomical causes: sunspots, our planet’s variable tilt and orbit [varying every 21,000 years, the planet’s “wobble” [cycling every 41,000 years], and variations in the earth’s orbit cycle [100,000 years]. SECOND, there are atmospheric causes: the gases causing the greenhouse effect, then there’s solar reflectivity due to clouds, dust and reflection off polar caps. THIRD, there are tectonic causes: that’s shifts of land masses and sea-floor spreading. There it is in a nutshell. One can see that atmospheric gas is just one cause of a change to climate.                                                                                                                                                                                                                                                                                                                                                           And, of these greenhouse gases, how much is CO2? ANSWER: Less than 1/10 of 1%. The vast majority of atmospheric gas is water vapour [which cannot be mitigated]. Historical evidence shows that in the last 600 million years, the atmosphere now contains less CO2 than ever before, [this is determined from ice core samples taken up to 2km. deep]. We need more CO2 not less. And CO2 is not a pollutant, it is vital to life. Humans need oxygen [and expel CO2], while vegetation must have CO2  and expel oxygen….the cycle of life! AND, of the tiny amount of CO2 in the atmosphere, human activities contribute an even tinier amount to that. In fact, plant decomposition adds more CO2 to the air than human activities such as coal-burning. But, does a rise in earth’s tenperature happen when there is an increase of CO2 in the atmosphere. NO! But you will have to take my word per the evidence available as I don’t want to get into all the detailed evidence, graphs, charts etc., but all this is available in textbooks or on-line. In summary: Yes, global warming is a real phenomenon, the earth’s temperature is increasing slightly, the greenhouse effect is real and mainly caused by water vapour, but this is minor because the MAIN cause of changing temperatures is due to the eccentricities of the earth’s orbit [it has never been constant] and variations in the SUN’S OUTPUT, [sunspots].                                                                                                                                                                                                                                                                             Some years ago, there was an ad. in the local paper for a symposium on the coming Ice Age. WHAT? We have some scientists warning of warming and here we have a symposium to be held by scientists at U.W.A. telling us we are heading into another Ice Age. Turns out that both are right – but the warmists are simply latching on to a natural phenomenon to panic us into actions we do not need to take. Explanation: Periods of alternating warming and cooling occur in marked cycles. Small-scale cycles of aprox.40yrs. exist within cycles of aprox.400yrs., which occur in cycles of 20,000yrs. which occur in clear cycles of 100,000yrs. The earth in fact only has a reprieve from ice ages for about 20,000 years. We have been warming now for roughly 18,000 years overall, [even though small ice ages happen in that period, such as happened in the 18th century]. So we are actually only a few thousand years from the next big freeze. We are NOT heading for a cataclysmic frying.
