David,

We know that global temperature is increasing--with expected global consequences. We have recorded CO2 levels directly--real time--for many decades now as well. We have separate estimates of use of carbon based fuels consistent with the temperature and CO2 measures. Looking back to earlier times with less powerful measures of both temperature and CO2, combining them with more recent findings, we believe that this temperature/CO2 relationship has accelerated the temperature increase in recent years. Hence, global warming. There may be many other factors that raise or lower global temperature--especially if measured over much longer periods of time--but such changes are not very easy to study short term.

I'm not sure that we can go as far as you have, and suppose a causal relationship between aircraft activity and changes in the jet streams, but I suspect that over the last 50 or 60 years, we have pretty good data on changes in the jet streams and frequency of high altitude flights. I doubt that such data would change our interpretations of global warming, but might well change our predictions of the distribution of rainfall. I'd bet that the data exists.
