We account for 5% of CO2. And also, I'm not an expert as you said in your last line. The warming cycle(yes I am saying it even though you didn't want me to) started in about 1850, which is too early for us to blame the burning of fossil fuels. Also, there has been data recorded that shows that average temperatures were higher than it is now, hundreds of years ago. As for the rapid glacial melting, there are also some glaciers that are actually expanding. There are many websites that explain this... Once I find a good one I will post it.
Ok here is one. This site clearly believes in global warming, and they explain that glaciers are affected more by other things that global warming.
Global Warming May Trigger Ice Sheet Growth
Also, do you have a good website with the IPCC data? If you do it would be helpful
