Pluto is roughly 40 times further from the sun than we are.  This implies something like 1600 time less sunlight than we get. You had better read your newspaper with a photomultiplier.  Also better make sure that you keep it warm; at Pluto's ambient temperatures newspaper is likely to shatter if you try to pick it up.

Sorry about the cold comfort. There are compensations to terrestrial global warming...

Cheers,
