So, in this diagram, I've tried to sum up all the current research on sea level rises. What will happen, when it will happen, and where the sea water is coming from.

It turned out that the swarms were coming down at sea - on any ships they could find, but also in the water itself.

I snapped this coming down from our first run, the sharp line at the top of the cloud bank made it seem like a sea that was slowly encroaching on the hut at the base of the lift.
