First, I would like to start off with saying, that this debate is going to be on science. If you make any posts trying to ‘ridicule’ or ‘insult’ me, they will be completely ignored, unless if you have included some sort of argument. I understand that most of you are going to come in here and say ‘Not this again!’ which is fine, I don’t want you here anyways.
I figured out the solution to the one argument you all came up with months ago, I just haven’t wanted to post it here, because of the negative responses from the skeptics on this website. But, I have decided I can just ignore all of you, so I am going to.
So without a further ado, my argument against Maulds:
[LEFT]Carbon Dioxide is such a small component of Earth’s atmosphere (380 ppmv) that the “slice” it represents in this chart is really only a “line” about 1/2 as thick as the line shown. Compared to former geologic times, Earth’s atmosphere is “CO2 impoverished.”[/LEFT]
[LEFT]In the last 600 million years of Earth’s history only the Carboniferous Period and our present age, the Quaternary Period, have
witnessed CO2 levels less than 400 ppm, except during periods of glacial expansion during ice ages.[/LEFT]
Late Carboniferous to Early Permian time (315 mya – 270 mya) is the only time period in the last 600 million years when both atmospheric CO2 and temperatures were as low as they are today (Quaternary Period).

There has historically been much more CO2 in our atmosphere than exists today. For example:
http://www.geocraft.com/WVFossils/PageMill_Images/bullet_pin1.gifDuring the Jurassic Period (200 mya), average CO2 concentrations were about 1800 ppm or about 4.7 times higher than today.
http://www.geocraft.com/WVFossils/PageMill_Images/bullet_pin1.gifThe highest concentrations of CO2 during all of the Paleozoic Era occurred during the Cambrian Period, nearly 7000 ppm – about 18 times higher than today.
http://www.geocraft.com/WVFossils/PageMill_Images/bullet_pin1.gifThe Carboniferous Period and the Ordovician Period were the only geological periods during the Paleozoic Era when global temperatures were as low as they are today. To the consternation of global warming proponents, the Late Ordovician Period was also an Ice Age while at the same time CO2 concentrations then were nearly 12 times higher than today – 4400 ppm.
According to greenhouse theory, Earth should have been exceedingly hot. Instead, global temperatures were no warmer than today. Clearly, other factors besides atmospheric carbon influence Earth temperatures and global warming.
All this argument proves is that Carbon, isn’t the only contributing factor to climate; and as it says in the last sentence, that’s all it wanted to prove:
“Clearly, other factors besides atmospheric carbon influence Earth temperatures and global warming.”
And they wasted their time, because we on the other side of the argument agree: There are and have been other contributing factors to climate change then CO2. Where we disagree, is that this warming trend is being driven by Carbon Dioxide. And we too have our own graphs to prove this:
The first graph shows how the environment alone would be effecting temperature’s. The sun, sun spots, oceans, etc. And what the temperature is actually doing. The second graph includes human activity with carbon. And suddenly a correlation reappears. Humans are the only variable in the climate that have changed in the past 150 years. Therefore, they are the only possible cause in the current warming trend, but still, not the only possibility in other climate shifts.
