In general, if the shape of the
daily temperature cycle is changed by increasing greenhouse gases [and there is a sufficiency of theoretical arguments to suggest that it could be (plenty of completely untested hypotheses which are soundly based in accepted physics)-RSB-, then the trends of that shape (the trend of the true 24 - hour
average temperature) may bear no resemblance at all to the trend in the
average of the
daily maximum and
minimum.
On a seasonal basis the ranges between the
