Quote by: xyzer  JohnMK ...interesting chart? Who was doing the measuring back in 1890? What sort of devices(other that a sniff test) were used for these measurements and where were they taken?
Where were the ice cores drawn? Is the CO2 concentration universal all over the globe,or are there differences in the concentrations?(seems like they should be higher near greater industial centers)? Could there be some interesting questions about the origin of all global temperature measurements before modern times? How and where were theytaken in some of the remoter areas of the world? Were the instumentas accurate and the data consistiently taken?
Just a few questions that the global climate doomsday types might consider? |
If you're questioning the validity of the data and their assessments, please cite the relevant papers and elaborate on them.
