If you had only one way to determine co2 levels and nothing to collaborate these calculations you could be right, but when you have dozens of pieces of data collabotating what the mud cores, ice core, fossil records, mineral deposits, etc, you should question your source that is trying to discredit a very sound methodology of calculating atmospheric composition.......
And again, can you come up with a global warming period that did not have high levels of co2????
And next, can you explain how you can dump billions of tons of gasses into the atmosphere, annually, and expect no changes?
And a little info on the author of the post you copied a link to:
Jaworowski is a global warming skeptic.
His works on ice cores were published in Jaworowski (1994, 1992) and in reports Jaworowski (1990, 1992).
Quote:
Jaworowski has suggested that the long-term CO2 record is an artifact caused by the structural changes of the ice with depth and by postcoring processes. However, increases in CO2 and CH4 concentrations in the Vostok core are similar for the last two glacial-interglacial transitions, even though only the most recent transition is located in the brittle zone. Such evidence argues that the atmospheric trace-gas signal is not strongly affected by the presence of the brittle zone. [1]
Similarly Hans Oeschger [2] states that "...Some of (Jaworowski's) statements are drastically wrong from the physical point of view".

Stephen Schneider said of him that "Jaworowski is perhaps even more contrarian than most, claiming that he can prove the climate is going to get colder through his work excavating glaciers on six different continents, which he says indicates what we should really be worrying about is 'The approaching new Ice Age...'."[2] Jaworowski wrote The current sunspot cycle is weaker than the preceding cycles, and the next two cycles will be even weaker. Bashkirtsev and Mishnich (2003)[3] expect that the minimum of the secular cycle of solar activity will occur between 2021 and 2026, which will result in the minimum global temperature of the surface air. The shift from warm to cool climate might have already started..
When approached to see if he would bet on future cooling, Jaworowski denied making any prediction, stating "I do not make my own detailed projections. In my paper I referred the reader to B&M paper, and that is all."[3]
Jaworowski published several papers (Jaworowski, 2007; Jaworowski, 1999; Jaworowski, 1997) in 21st Century Science and Technology, a non-refereed magazine published by Lyndon LaRouche.[4]
Jaworowski has also written that the movement to remove lead from gasoline was based on a "stupid and fraudulent myth," and that lead levels in the human bloodstream are not significantly affected by the use of leaded gasoline. [5]

You also need to understand that this man is not arguing that there is not link between co2 and warming, he is trying to say that the co2 now is nearly the same as co2 before 1850!!!!!!!!!!!!!!!!!!!!!!!!! The amount of co2 has increased by nearly 35 parts per billion in my lifetime, which would lead a pre-schooler to believe he is wrong..........
Also, if this guy is who you are relying on, he is trying to say we are heading to a cooling of the planet, and he maybe right..... And it does not matter, a drastic change in climate in either direction will make the planet hostile to the life that has been evolving for the past 90 million years............
Lastly, I never said you do not know what you are talking about, I only asked for more information..............
