Causes?

, in addition to the overabundance of toilet flushing there's gravity, melankovitch climate cycles, solar radiation, current disarray of earths magnetic field, Atlantic and Pacific decadel oscillations . Lots of reasons why and we find out more everyday, and as much as some would like to think otherwise there isn't one damn thing you can do to change any of it. Like a big truck, going down a big hill, with no brakes, sea levels are gonna rise. So go out buy some mountain property inland while it's still cheap your great, great great grand children will think well of you. Because it will become very costly ocean front property in the near future.
