According to Al Gore and the United Nations Intergovernmental Panel on Climate Change Global Warming with all its dire consequences is the result of the increase of Carbon Dioxide (CO2) in the atmosphere from the burning of fossil fuels to power our automobiles and airplanes, our electric power generating plants and our factories. How much do you know about CO2? Let me ask some questions:
Question 1. What percentage of the atmosphere do you think is CO2?
Question 2. What percentage of the CO2 is man-made?
Question 3. Is CO2 is a pollutant?
Question 4. Have you ever seen any evidence that CO2 causes a greenhouse effect?
The answers to these questions are key in evaluating the global warming scare. However, a sampling with these questions proved almost no one knows the correct answers. Without this basic knowledge there is no way you can logically decide whether Global warming is really happening and whether it is natural or not.
Here are some respondents' perceptions followed by the correct answers.
Question 1. What percentage of the air is CO2?
Respondents' answers: nearly all were 20% - 40%, the highest was 75% while the lowest were 10%- 2%.
The Correct Answer: CO2 is less than a mere four 100ths of 1%! As a decimal it is 0.038%. As a fraction it is 1/27th of 1%. (Measurements for CO2 vary from one source to another from 0.036%- 0.039% due to the difficulty in measuring such a small quantity and due to changes in wind direction e.g. whether the air flow is from an industrialized region or a volcanic emission etc)
Nitrogen is just over 78%, Oxygen is just under 21% and Argon is almost 1%. CO2 is a minute trace gas at 0.038%. For a detailed breakup of the atmosphere go to: http://en.wikipedia.org/wiki/Atmosphere_of_Earth#Composition
Question 2. What percentage of CO2 is man-made?
Respondents' answers ranged from as high as 100%, with most estimating it to be between 25% and 75%.
The Correct Answer: Nature produces nearly all of it. Humans produce only 3%. As a decimal it is a minuscule 0.001% of the air. All of mankind produces only one molecule of CO2 in around every 90,000 air molecules! Yes, that's all.
Question 3. Is CO2 is a pollutant?
Respondents' answers: All thought it was a pollutant, at least to some degree.
The Correct Answer: CO2 is a harmless, trace gas. It is as necessary for life - just as oxygen and nitrogen are. It is essential to photosynthesis, the basic process that makes plants grow. Without CO2 there would be no crops, no flowers, trees, grass or bushes. Co2 is a natural gas. It is clear, tasteless and odorless. It is in no way a pollutant.
Calling CO2 a 'pollutant' leads many to wrongly think of it as black, grey or white smoke. Because the media deceitfully show white or grey 'smoke' coming out of power station cooling towers, most think this is CO2. It is not: it's just steam (water vapor) condensing in the air. CO2 is invisible: just breathe out and see. Look at it bubbling out of your soft drinks, beer or sparkling wine. No one considers that a pollutant - because it's not.
Question 4. Have you seen any evidence that CO2 causes a greenhouse effect?
Respondents' answers: Most did not know of any definite proof. Some said they thought the melting of the Arctic and glaciers was possibly proof.
The Correct Answer: There is no proof at all. The Intergovernmental Panel for Climate Change (the IPCC) has never produced any proof. There are, however the following proofs that it can't cause a greenhouse effect.
• It is true that CO2 can absorb heat a little faster than nitrogen and oxygen but it becomes no hotter because it cannot absorb anymore heat than there is available to the other gases. This is against the laws of thermodynamics. All gases share their heat with the other gases. Gas molecules fly around and are constantly colliding with other gas molecules so they immediately lose any excess heat to other molecules during these collisions. That's why the air is all one temperature in any limited volume.
• Even if CO2 levels were many times higher, radiative heating physics shows that it would make virtually no difference to temperature because it has a very limited heating ability. With CO2, the more there is, the less it heats because it quickly becomes saturated. For a detailed explanation go to: http://www.geocraft.com/WVFossils/greenhouse_data.html
The following facts show that even high levels of CO2 can make almost no impact on heating the atmosphere.
1. Glasshouses with high levels of CO2 - hundreds of times higher than in the air to make plants grow faster - heat up during the day to the same temperature as glasshouses with air in them. This is also true for bottles of pure CO2 compared to ones with air.
2. The planets Venus and Mars have atmospheres that are almost entirely CO2 (97%) yet they have no 'runaway' greenhouse heating effect. Their temperatures are stable.
3. The geological record over hundreds of millions of years has shown that CO2 has had no affect whatsoever on climate. At times, CO2 was hundreds of times higher, yet there were ice ages.
4. In recent times when Earth was considerably warmer during the Roman Warming and the Medieval Warming, the higher temperatures then were totally natural because there was no industrialization back then.
Over the last few years Earth has had much colder winters perhaps due to very few magnetic storms on the Sun. These four increasingly colder winters have been particularly noticeable in the northern hemisphere where most of the land is. Because of this, the Arctic has re-frozen and glaciers that were receding are now surging due to the heavy snow falls. The Arctic showed some melting around its edges from the mid 90s to the mid 2000s due to the very high level of solar storm activity at that time. But as the Sun is now entering probably 2-4 decades of low solar activity, this is expected to cause global cooling.
The climate has always been naturally cyclic and variable due to numerous natural drivers of which CO2 is not one. Over millions of years the climate has shown far greater changes in the geological record than we have seen over the last 200 hundred years - and there was no industrialization back then. The very minor variations we have witnessed over the last 100 years have all occurred several times even in that short period. Today's changes in climate are common and completely natural. There are now over 50 books that provide numerous reasons why man-made global warming is false.
What I presented here was mostly written by an Australian man, Gregg D Thompson. I edited and excerpted from his climate posting. He is a Climate Researcher, Astronomer and Environmentalist. He has written two science books, been Business Manager and Director of 3 companies, Author of science magazine articles and Designer and project manager of special effects attractions. He is also a Nature photographer.
When you hear on the news about the government regulating greenhouse gases or the pollutant CO2, another news writer, reporter or editor is displaying dulability, ignorance or bias.
This situation drives me nuts. But, maybe I was sort of nutty before.
