First, do you all remember that chart that Al Gore showed in his movie "An inconvenient truth?" In case you don't, here it is:

So, I've looked at this chart many times and the every time I looked at it, there seemed to be something that was just not right. Throughout the Earths history the lines seemed to always match up until now. Now, the CO2 line has skyrocketed but the temperature line is still far below peak. Why is that? Simple. CO2 DOES NOT DRIVE TEMPERATURE! The fact is, temperature actually drives CO2. So, for the history of the Earth, as temperatures would go up, it would cause an increase in CO2 which is why the chart always seemed to match until humans came into the picture and we drove up CO2 ourselves. So, why does CO2 go up when the Earths temperature goes up? The answer is at the beach! Oceans hold massive amounts of CO2, when the oceans are cooler, they absorb CO2, but when the oceans temperatures get warmer, the oceans release CO2. Now it takes hundreds of years of warmer temperatures to heat the oceans to the point that they begin to release this CO2, which is why the data actually shows a lag of between 800 and 1,000 years between temperature rise and CO2rise. So, the Earths global temperatures go up and CO2 levels increase, lagging behind temperature by 800 - 1,000 years. Then the Earths temperatures begin to cool and CO2 decreases, lagging behind by 800 - 1,000 years. Bottom line, increases in CO2 DO NOT cause an increase in global temperatures. If it did, then the above chart would show current temperatures above all the previous peaks since CO2 is "higher than ever"
Now let's talk about something else. Data manipulation. The question is this: Is CO2 at an all time high right now? The answer might surprise you. You know that chart that I showed you above, the one that Al Gore used to show just how much greater CO2 is now than ever before? Have you ever wondered where he got that data? Well, I am going to show you exactly how he got that data and it is going to freak you out. Here is the raw chart Al Gore uses:

Okay seems pretty straight forward. Seems to show that CO2 has absolutely increased a great deal. BUT WAIT. It turns out that this chart is actually of CO2 data that has been collected using 2 different methods and from 2 different places.
The first part of the chart is made from ice core data collected in siple Antarctica. The second half of the chart is from air flask samples from Mauna Loa Hawaii. Humm, aren't there a lot of volcanoes in Hawaii that spew out CO2? At any rate, here are the charts before the full manipulation happens:

Notice how there is data missing between 1891 and 1950? Also notice how CO2 seems to drop between those dates? So what do they do obvucate the facts? Well, they just shift the chart 83 years masking the falling CO2 and when the use the data they try to make you belive it all came from the same location using the same collection methods. Does this make any sense? It does if they are trying to decieve you.
First why would they use 2 different types of collection methods? Knowing that direct air sampling is a more direct and precise measurement of CO2 in the air (as was done at Mauna Loa), did they just not have air flask data that went back far enough? Well, as it turns out, they did. So, why then would they not just use these samples? When you see the chart you will understand why:

So,now you see. If they showed you this data, you're going to say "Hey it looks like CO2 was actually higher than today back in the 1800's" and you know what? You would be correct. So, instead of showing this, they create their own charts by combining to different charts, all in an effort to make you believe what they are telling you.
Add to that the unreliability of ice core data and you have a real mess. Wait what was that? Did I just say that ice core data is unreliable? YES I DID? Here let me allow the smart guys to explain it by quoting them. I will also link directly to where you can find the quote for yourselves.
"The air occluded in ice sheets and glaciers has, in general, a younger age (defined as the time after its isolation from the atmosphere) than the surrounding ice matrix because snow is first transformed into open porous firn, in which the air can exchange with the atmosphere. Only at a certain depth (firn-ice transition) the pores are pinched off and the air is definitely isolated from the atmosphere. The firn-ice transition depth is at around 70 m under present climatic conditions at Summit, central Greenland. The air at this depth is roughly 10 years old due to diffusive mixing, whereas the ice is about 220 years old. This results in an age difference between the air and the ice of 210 years. This difference depends on temperature and accumulation rate and did not thus not remain constant during the past." Here's the link

So, the bottom line is, don't just take what you hear at face value. Question and investigate for yourselves before you make up your mind. Heck you have almost all of the worlds knowledge at your finger tips SO USE IT.
