The Seven Levels of Aviation (not for the humor-impaired)

No such thing a warming limited to Global, Mars ice caps
receding, Rovers still running, atmosphere getting thicker,
Pluto warmer, Jupiter has a second spot, comets brighter;
the whole damned solar system is getting a heat wave.

I have read about some of this, also. The only explanation in that case is
that solar output has increased, in which case human activity may not make any
difference at all, which comes as no surprise (human beings like to
overestimate their influence on their environment).
