A reicing courtesy of the conveyor shutting down would be a best case scenario.

The worst possibility is a recasting of the Permian extinction where the increased heat nixes the O2 dissolved in the cold seawater. Animals die and sink, sulpher content increases as the oceans become acidic killing most of ocean life and making the water inhospitable to phytoplankton. The ocean burps methane and sulpheric gases, stops producing adequate 02 and the creatures on the land start dying off in great numbers.

Next to that a new ice age seems to be a pretty good day.
