The Five Things You Need To Know About The Global Warming Myth
1). Carbon Dioxide, CO2, is not a pollutant. Carbon Dioxide is a naturally occurring element in our atmosphere. Carbon Dioxide is no more a pollutant than say, oxygen or nitrogen. Without CO2 there would be no life on earth. http://www.eoearth.org/article/Carbon_cycle . Carbon Dioxide is the food which keeps plants alive. Through photosynthesis plants transform CO2 into plant food. Oxygen is produced as a waste product. All living things are dependent on this ”Cycle”. http://earthobservatory.nasa.gov/Features/CarbonCycle/carbon_cycle2.php
Carbon Dioxide is called a “green house gas” because it allows visable light to pass through while it absorbs infrared and near infrared rays. http://en.wikipedia.org/wiki/Carbon_dioxide
The human body produces CO2 naturally. The Human Respiration System is the system that controls the exchange of oxygen for CO2 in the Human Body. Everytime you breath out you are exhaling CO2.
Carbon Dioxide is not a pollutant. Carbon Dioxide is a natural atmospheric element. All life on earth is dependent on CO2. Without CO2 there would be no life on earth. Compared to past history, the Earth’s atmosphere is currently CO2 “impoverished”.On average, there is less CO2 in the atmosphere today than there has been since life formed on earth.
2). Even at present levels, Carbon Dioxide is a trace gas. Current CO2 levels are only a small fraction of the Earths atmosphere, CO2 represents less than 1/2 of one percent of the atmosphere today.
The CO2 content in the atmosphere is measured in terms of CO2 parts per million (ppm) by volume. At present the globally averaged concentration of CO2 is stated as 387 PPM. http://en.wikipedia.org/wiki/Carbon_dioxide For every million parts (1,000,000,000 parts) in the atmosphere 387 of those parts are CO2. CO2 levels have increased over the past 50 years from 320 PPM to today’s 387 PPM, an increase of 67 PPM.
The CO2 level today, 387 PPM, can be compared to with a level of 8000 PPM (20X todays levels) 500 million years ago or CO2 levels of 2000 – 3000 PPM (5 to 6 times todays levels) during the Jurasic Period, when the Great Dinosaurs roamed the earth. http://earthguide.ucsd.edu/virtualmuseum/climatechange2/07_1.shtml
During the ice ages CO2 levels fell to between 200PPM and 280 PPM. During interglacial periods the CO2 Level has been measured at between 280 – 310 PPM. One does not need a calculator to see that current CO2 levels are much nearer to those recorded during the Ice Age and the interglacial periods than that time when Earth’s great green forests were first formed. CO2 is essential for plant life and growth.
In a longer historical context – Earth’s current CO2 Levels are quite low. http://ff.org/centers/csspp/library/co2weekly/2005-08-18/dioxide.htm
In fact, in Earth’s entire history there have only been two prior periods where CO2 levels were this low, . http://ff.org/centers/csspp/library/co2weekly/2005-08-18/dioxide.htm , ”Today, at 370 PPM our atmosphere is CO2-impoverished” http://www.geocraft.com/WVFossils/Carboniferous climate.html . “So far the signal of a discernible human contribution to global climate change has not emerged from this natural variability or background noise.”
“Without the warming caused by natural levels of CO2 and water vapor in our atmosphere, the average surface temperature of our planet would be well below freezing.” http://www.whoi.edu/oceanus/viewArticle.do?id=17726
3). Human’s produce a very small percentage of the CO2 found in the Atmosphere:
Over 95% of the total CO2 emissions into our atmosphere would occur even if humans were not present on Earth. For example, the natural decay of organic material in forests and grasslands, such as dead trees and grasses, results in the release of about 220 gigatonnes of carbon dioxide every year. This carbon dioxide alone is over 8 times the amount emitted by humans. There are many other sources of CO2 in the Earth’s atmopshere.
The Earth’s Oceans contain 50 times more CO2 than the atmosphere. http://en.wikipedia.org/wiki/Carbon_dioxide , http://www.whoi.edu/oceanus/viewArticle.do?id=17726 .
If 5% of todays CO2 is produced by human activity (95% would occur if no humans existed on the planet) then a simple calculation will provide us with an absolute figure for Human CO2 production. 387 PPM CO2 x 5% = 19.35 PPM.
How does this compare to the Earth’s total atmosphere?
Well for every 1 Million (1,000,000) parts of atmosphere, there are Seven Hundred Eighty One Thousand (781,000) parts Nitrogen, Two Hundred Ten Thousand (210,000) parts Oxygen, Nine Thousand Parts (9,000) Argon and Three Hundred Eighty Seven Parts (387) CO2. All other gases account for the remaining 500 plus parts. http://web.rollins.edu/~jsiry/VapgasAt.htm
Total CO2 presence in the atmosphere represents less than 4/10 of 1 percent. (CO2 is less than half of one percent of the atmosphere – If the atmosphere were a $100 dollar bill - all the CO2 in the atmosphere would equal 40 cents). http://www.geocraft.com/WVFossils/atmos_gases.html . Man made CO2 represents 1/20th of that amount or 2 cents out of every $100 Dollar Bill.
I asked a scientific friend to help me conceptualize this amount with an everyday example. Just how big is the total contribution of manmade CO2 to the Earth’s atmosphere? The friend couldn’t remember where he first heard this comparison, so I cannot provide a site, he didn’t want to take personal credit, but here goes; “Imagine a Farmers field 100 miles long and 100 miles wide. It is filled with corn. A mouse sitting in the middle of the field farts.” Ask yourself,”Will the fart affect the crop?” As much as manmade CO2 affects our global temperatures.
4). Temperature Impacts CO2 Level - CO2 levels do not drive Temperature Change
First, CO2 levels rise and fall with the seasons or time of day. CO2 levels rise in the Autumn and Winter as green plants go dormant or die. The plants cease to “process” CO2 as part of their food chain. In the spring and summer CO2 levels fall as these same plants come back to life and consume CO2 in photosyntesis. Likewise CO2 levels fluctuate in the night and day. http://www.learner.org/courses/envsci/visual/animation.php?shortname=anm_co2_levels

CO2 levels follow changes in temperature, not the other way around. http://icecap.us/images/uploads/CO2,Temperaturesandiceages-f.pdf .
“ There is, overall, a good match between temperature and CO2 and temperature. One important piece of information that can be determined from ice core data is whether changes in temperature follow or proceed changes in CO2.” “Changes in temperature precede changes in CO2″ http://www.brighton73.freeserve.co.uk/gw/paleo/400000yrfig.htm
First, the total increaase in Global Temperatures over the last 100 years is ………. 7/10s of one degree. That is right, total Global warming over the Century is less than 1 degree. During that same century the Sun’s measurable intensity or heat has increased.
“Actual climate history shows no such correlation (that CO2 caused an increase in temperature) and there is no compelling evidence that the recent rise in temperature was caused by CO2. http://www.friendsofscience.org/assets/documents/FOS%20Essay/Climate_Change_Science.html#Correlation
Numerous papers published in major peer-reviewed scientific journals shows the Sun is the primary driver of climate change. http://www.co2science.org/articles/V6/N26/EDIT.php , http://www.worldclimatereport.com/index.php/2007/03/16/the-coming-global-cooling/ , http://www.friendsofscience.org/assets/documents/FOS%20Essay/Climate_Change_Science.html#Sun_Activity , http://www.geocraft.com/WVFossils/ice_ages.html
5). Current Global Warming trends are neither catastrophic nor are they unusual given the Earth’s very recent past.
Global Warming Alarmists state that man made CO2 is responsible for what is becoming a catastrophic increase in Global temperatures. (You know the 1 degree increase in the last century).
Science has told us for decades (decades prior to the Global Warming Alarmist taking the stage) that earth’s last ice age (referred to as the “little ice age”) began sometime near the year 1400 and lasted until approximately 1860. This “little ice age” was responsible for disasters like the “Irish Potato Famine”. The end of the “little ice age” was not preceeded by an increase in CO2 levels. Other natural causes were responsible for the “global warming” which followed the end of the “little ice age” and continues to this date. http://www.geocraft.com/WVFossils/ice_ages.html , http://www.friendsofscience.org/assets/documents/FOS%20Essay/Climate_Change_Science.html#Hockey
During the Middle Ages (1066 – 1485) a time that saw the Norman’s conquest of England, King Richard The Lion Hearted, The Crusades – all 7 of them, the Early Italian Renaissance - a period of time long before the ”Industrial Revolution”, mankind contributed very little to Global CO2 levels. The Middle Ages experienced a period of global warming that exceeds the global warming of today. Yes, temperatures were higher than they are now, significantly higher. http://www.friendsofscience.org/assets/documents/FOS%20Essay/Climate_Change_Science.html#Hockey , http://www.theage.com.au/articles/2003/04/06/1049567563628.html ,
“A review of more than 240 scientific studies has shown that today’s temperatures are neither the “warmest ever” nor are the Temperatures producing extreme conditions “never seen before”. The findings of these 240 studies stand in stark contrast to the claims of the alarmists. The findings prove that the world had a medieval warm period between the ninth and 14th centuries, with world temperatures significantly higher than today’s. They also confirm claims that a little Ice Age began in about 1300, with the world cooling dramatically. Just before the turn of the century, in 1900, the world began to warm up, but as of today, has still to reach the balmy temperatures of the Middle Ages. The end of the little Ice Age is significant because it implies that the records used by climate scientists (THE ALARMISTS) date from when the Earth was relatively cold, thereby exaggerating the significance of today’s temperature rise. According to the researchers, the evidence confirms suspicions that today’s alleged “unprecedented” temperatures are simply the result of examining temperature change over too short a period. http://www.theage.com.au/articles/2003/04/06/1049567563628.html
The Global Warming Alarmists have choosen the “Little Ice Age” to begin their temperature measurements and comparisons. By choosing the coldest period in Earth’s history over the last 10,000 years, the Alarmists are assured of finding data that will show a warming trend. But the warming trend is not unusual when compared to all of Earth’s prior warming trends.
Philip Stott, emeritus professor of bio-geography at the University of London, said: “What has been forgotten in all the discussion about global warming is a proper sense of history.” http://www.theage.com.au/articles/2003/04/06/1049567563628.html , http://www.michaelkeller.com/news/news575.htm , http://www.stanford.edu/~moore/history_health.html , http://www.freerepublic.com/focus/f-news/886494/posts , http://www.climateaudit.org/?p=2514
If mankind were to cease all economic production and cease buring all carbon fuels, at best, a 2% reduction in CO2 levels could be had. Additional reductions from manking would need to involve an end to “respiration” – manking would need to stop breathing. Having achieved these miniscule reductions, at fantastic cost and loss of personal freedom, nature could, in the bat of an eye, dramatically reverse any man made reduction. You see, temperature drives the CO2 level, CO2 levels do not drive temperature.

Recent studies call into question wether Global Warming is continuing - the studies refute the wild claims concerning the amount of ”warming” that occurred in the 1990’s. Even the ultra-green “Discovery Channel” has noted studies which indicate “global warming” is on “hold” and may not reappear for decades. That “Global Temperatures have flatlined since 2001″. http://www.msnbc.msn.com/id/29469287/
The Boston Globe has asked, “Where is the Global Warming?”, before noting, “But for many people, the science of climate change is not nearly as important as the religion of climate change. When Al Gore insisted yet again at a conference last Thursday that there can be no debate about global warming, he was speaking not with the authority of a man of science, but with the closed-minded dogmatism of a religious zealot. Dogma and zealotry have their virtues, no doubt. But if we want to understand where global warming has gone, those arenít the tools we need.” http://www.boston.com/bostonglobe/editorial_opinion/oped/articles/2009/03/08/wheres_global_warming/
