I'm aware of the more ovoid structure of Mars orbit, its distance 
varies from the Earth by about 40 million miles, which is pretty damn 
dramatic, but this happens during the course of its 600+ day year, 
every year, and we've been there for years now, so I'm assuming they 
are talking about something out of the ordinary.  I wasn't aware of 
the term MIlankovitch Cycles, that's interesting.  So if we know all 
this, why are some people so obsessed with supposed man made global warming?
