Firstly I said: CO2 levels are approaching levels not seen since Dinosaur times: Source: http://www.biocab.org/Geological_Timescale.jpg We are not there yet, but we are approaching it. Notice the sharp increase in CO2 after being stable the last million years.
Secondly, the Dinosaurs all died out, who is to say CO2 levels were innocent in the extinction? Do you have any proof of this? Models? Evidence? (see, your argument against you, no fun right? Either way, this was not meant to be a serious argument.)
Thirdly, it is irrelevant, as I perfectly explained earlier. We are not looking at your cabin temperatures last summer, we are looking at a global temperature increase since the industrial revolution. If the Industrial Revolution is not the culprit, who is? I would love for you to prove me wrong on this, and if you manage it, you will get the nobel price for sure.
Actually no. The average has not increased in the last 17 years, and hence why the IPCC is scrambling to explain it (they have not been able to so far).
Excellent, you have proven that global warming does not follow a linear line. The point still stands. Look at the bigger picture than the last couple of decades. As I said earlier, it's complicated. If you look at the graph at the top of my post, you can see we may have turned a cooling period around with the industrial revolution, what do you think will happen when we are supposed to have a natural rise in temperatures, as well as the "possible" human made rise?
Edit: http://www.ncdc.noaa.gov/sotc/service/global/global-land-ocean-mntp-anom/201201-201212.png found this. Notice the plateau in the 40's to 60's? This is not new, and we will very likely expect a sudden rise in global temperatures the coming decades if you believe that graph. Will that persuade you if it happens? Also notice that we haven't had a real decrease in global temperature since the 40's. That's a really long time for it just keep climbing or "plateauing". In 2040 if we keep going as we have, we will have had a steady increase in global temperature over 100 years, and that is probably unprecedented.
