Warpstorm,
For scenarios, polar regions are a toggleable preference.
You have no icecap cause you nuked everyone and your warm expressions of joy and delight melted all the ice.
Well at least we have a cylinder world instead of a flat world. Maybe in a future revision we will have a round world.
With the ice melting above Canada some ships are already going thru the northern polar route instead of going around. With navies taking so long, the option of crossing over to the North or South seems like it would add another dimension to the game.
{Good thing I am a perfect coder ;-) }
