I wanted to study how much carbon dioxide is needed to produce a maximum warming effect in a greenhouse. So, I have build some mini-greenhouses, whose CO2 content were varied and temperatures  measured. Dia 1.

Tools for adding the carbon dioxide Dia 2.

Mini-greenhouses were directed to sun with my solar tracking sundial. Dia 3.

Results of my experiment are available  here. I hope that somebody, who lives in a place with more sunshine, will continue the experiment.

FYI read this article http://www.scientificamerican.com/article.cfm?id=global-average-temperatures-are-close-to-11000-year-peak I really doubt that the IPCC and so many other researchers are wrong. there are many natural factors effecting climate and although CO2 is an IR absorber methane is worse. this all gets more complicated because higher temp produces more cloud and thus a higher albedo. all this aside well done for actually attempting to collect your own data there is nothing wrong in trying to confirm what ligature tells us.

Look up the data for ice samples taken in Greenland (I think, it's been a while since I read the data) and the percentages of gases enclosed measured by gas chromatography. Anyway these are deep core samples of ice dating to the 1400's and even farther back. If you look at recorded temperature versus the content of CO2 in the atmosphere, there is actually a reverse correlation to CO2 and temperature, in other words as the temperatures get colder, CO2 levels rise and vice versa, with a slight lag at abrupt changes. CO2 is such a miniscule component of atmospheric greenhouse gases (water vapor being the greatest) that it's effect is nominal at best. Also plug any data in the so called "hockey stick" graph equation (NL Ball stats for example) and you still get a hockey stick because there is a proven yet for some reason, unheralded flaw in the equation. You can BELIEVE anything you wish, but actual data over the millenia is against you.
Regarding this article, the solar tracker is great and I think it's excellent this person decided to get more hands on experience with measuring how CO2 can act as an insulator. <u>However I think the instruments are insufficient depth to simulate infrared getting trapped in an atmosphere. </u>But it really says something that the author was able to get any results at all at this scale.
I don't mean to be a troll. Your design is nice and well thought out. You should use your talents on more useful research. Anthro-progenic Global Warming is a scam started by General Electric in the 80's to sell a new generation of &quot;Green&quot; products. There is even an internal memo stating that very thing. (can't find it currently or I would link) Follow the money. Al Gore is getting stinking rich off his role in the scam. The myth has been further perpetuated by egotistical and gullible naturalist. I say egotistical because man has a tiny effect on the planet as a whole. Man has, only slightly, effected the weather around large metropolitan areas. Rain storms seem to avoid the vertically radiated heat from asphalt and concrete. Other than that the planet is much larger and more resilient than we could possibly destroy. (nuke excluded from statement) If you study the known history of CO2, you will find that the levels of CO2 increase after a warming trend begins. That means it is an effect of the warming cycle not the cause. Then after a warming cycle you usually get a cooling cycle. Maybe that means that CO2 is the cause of Global Cooling. (I doubt that) The main factor in the increase/decrease in global temp is the Sun's cycle of sun spot activity. Mars and Venus average temperatures follow the averages of the earth.
Please tell me about these GE Green products, they don't seem to have made much of an impact in the UK.<br> <br> L<br>
You are kidding right? Do a Google search for GE green products. Almost everything green being sold to the US Gov is made by GE. There was a company wide marketing campaign back around the end of the global cooling scare. They were going to be ahead of everyone else going &quot;Green&quot;. I am still looking for the memo again. Last I saw of it was a couple years ago.
<br> Web-link?<br> <br> L<br>
I'm still looking... Here is a link for a good collection of all sorts of data. <a href="http://schnittshow.newsradio610.com/pages/globalwarming.html" rel="nofollow">http://schnittshow.newsradio610.com/pages/globalwarming.html</a>
Wrong way to go about it. Measuring CO<sub>2</sub> is pretty easy - IR spectrophotometer for one. But other people already measure atmospheric&nbsp; CO<sub>2</sub> and report it. What extra value do you get out of these?<br> <br> L<br>
I am not measuring CO2. I am trying to measure its warming effect, if it has any, and according to my results, in a global scale it has not.
<br> Mmmm, but if you're not looking at &quot;global&quot; you're also not looking at a greenhouse (with some ventilation and plants and soil in it). Do it in a greenhouse,<br> I don't think you'll get meaningful results from the tubes beyond what maths/physics could tell you (about the greenhouse).<br> <br> L<br>
If you do'nt like my measurements, I challenge you to make your own. The sky is free and the sun is there.
<br> I have no &quot;dislike&quot; of your data, as a scientist I'm questioning the relevance / significance of the results.<br> The CO<sub>2</sub> effect can be done with mathematics, the proof you offer is either irrelevant or has been given already&nbsp; a <em>long</em> time ago. People were talking <a href="http://en.wikipedia.org/wiki/Greenhouse_effect" rel="nofollow">&quot;greenhouse effect&quot; </a>before you were born.<br> <br> L<br>
