I'm not sure what studies you are looking at that suggest that the amount of CO2 hasn't increased substantially over time but actual studies show that the amount of CO2 in the atmosphere has increased since the industrial revolution. Also people put CO2 in greenhouses because it blocks the short wave radiation from leaving the greenhouse which naturally warms it and increases growth ie GREENHOUSE EFFECT. Just because you think that your too old to believe something doesn't mean it isn't real.
Also try using scholarly peered reviewed journals for your sources. Anybody can put something on the internet if it is peer-reviewed then it is acurate.

LP I thought you may want to read this peer review article.



Washington DC – An abundance of new peer-reviewed studies, analyses, and data error discoveries in the last several months has prompted scientists to declare that fear of catastrophic man-made global warming “bites the dust” and the scientific underpinnings for alarm may be “falling apart.” The latest study to cast doubt on climate fears finds that even a doubling of atmospheric carbon dioxide would not have the previously predicted dire impacts on global temperatures. This new study is not unique, as a host of recent peer-reviewed studies have cast a chill on global warming fears.
