2020 is a safe bet. From watching TheCryosphere i'd say 2015 is a possibility. Any tankers?

I got 2012 in the pool.  The Mayan prediction for climactic disaster of some sort.  Will it include climactic climate disaster?  That's my guess.  

I think the ice is melting at an ever increasing exponential rate and that will stop the ocean conveyor that powers the Gulf Stream.  Putting north america and europe into an ice age.  That'll cool things off.

How long before it goes back to a more usual pattern?  as long as it takes to reform enough ice, to reflect enough solar heat, to offset the ever more serious excess GHG problem.  Imagine the increase in fossil fuel consumption and GHG release from longer winters in Europe and the US.

This is going to be a global panic.

Will ice melt throw off the Earth's motion somehow effecting the seasonal solar angle?  The weight of ice and water has remade the surface of the Earth for billions of years.  Has it changed the orbital motion as well?  The leap second added every few years because of slowing rotation is due to tidal pull.

so this talk about the antarctic ice INCREASING while the artic is decreasing is bunk, right?

as long as they leave it there.
