Hacked Emails Show Climate Science Ridden with Rancor

No they are not evenly distributed due to air currents and differences in locally produced CO2 (both from natural such as forest fires, and man made causes), which is why i say localized, however ice cores are drawn from areas both in the northern and southern hemispheres. It does though indicate general trends in CO2 concentrations across the globe. To my knowledge though, CO2 tends to concentrate more at the poles, which is why warming there is higher then the global average.

The data should all come from ice core samples only, but it takes a few years for the snow to turn to impermeable ice which permanently traps air, so there is a lag period. Good scientists would not take air samples above the impermeable ice. As for that chart, I can't speak of it as I do not no the source. But the 0 point is 1950 and that area doesn't quite match the information I have (but it does continue to climb). If you like I can dig up some data.
