Sawz:

The word "global" has two distinct meanings which you should differentiate between. One means referring to the globe.   The other means throughout an entire system or frame of reference.

Bruce:

Your argument appears to have some merit. This graph for example has a trend that is consistent with the planetary temperature trends I have linked to elsewhere. It is not as closely correlated as the CO2 graphs I have also linked to but it does align with the general trend. I don't think we have all the data though.
