In general, yes, repeating to ourselves "It's just a game, I should really just relax" is probably the way out.

I do like radiant heat from corruption energy making a permanent land breeze (incidentally pushing precipitation away from the interior of the country) as an explanation for Aram's ludicrous climate, but, again, the deserts pre-date the wastelands.

A simpler hand-wave is that since the dragons needed a magical element of some sort for sustenance, their biology was radically different, and their bones are made of some other set of compounds that was non-digestible by regular decomposers and less liable to erosion.
