Hi again, It has been a while

I have a question to the scientists out there,
Would there be more CO2 in the atmosphere if ice melts, like the glaciers have since we came out of the ice age?
And by looking at this lovely little chart would you come to the same conclusion as me that it looks like we (humans) have absolutely nothing to do with global warming?


The graph above shows the temperature changes of the lower troposphere from the surface up to about 8 km as determined from the average of two analyses of satellite data. The best fit line from January 2002 to April 2009 indicates a decline of 0.25 Celsius/decade. The Sun's activity, which was increasing through most of the 20th century, has recently become quiet, causing a change of trend. The green line shows the CO2 concentration in the atmosphere, as measured at Mauna Loa, Hawaii. [4]

Just something to ponder
