The hottest year in the last decade was 1936 when Co2 levels were down, and when the co2 levels were higher in later decades co2 was higher, Co2 levels are so low really compared to other gasses in the atmosphere that it is very strange to correlate a connection with global warming.
Have a look at historical data and something strange has occurred with interpretation. The graphs are not big enough.
The earth has cooled at times and heated up, glaciers have retreated and also grown, the antartic ice sheet isn't melting.
