Even the measurement of atmospheric CO2 hasn't been subject to proper scrutiny. Almost all figures are based on the data from Mauna Loa and they do generally show a steady increase. However Hawaii is not as isolated from the industrial world as many seem to believe and Mauna Loa at 3,400 m is certainly high enough to avoid surface produced CO2 variations. However a major source of CO2 at altitude comes directly from aircraft and Hawaii has a thriving and increasing air transport system. It is the major means of transport of people from island to island and the activity has increased over the same period as the CO2 measurement have also been shown to have increased. Coincidence? Maybe, but where is the graph that relates air traffic in Hawaii with Mauna Loa's CO2 data? If there is no relationship, it should be easy to show that as all the figures are easily available. I suspect you will never see the comparison simply because it will demonstrate an inconvenient doubt! Air travel around the islands tends to have seasonal variation as well increasing in the peak tourist seasons and decreasing during less popular periods. Just check the graphs here, esrl.noaa.gov and see if you can pick the top tourist travel periods...
