I think ice sheets break off because of difference in rotational speeds. Giant ice sheets that are closer to the poles move slower than the part closer toward the equator. The ice sheets always breaks off nearest to the poles if anyone noticed. If it was because of temps.. it would melt the edges off and break off the side furtherst away from the pole. And even in that case of temperature.. temperatures is warmer away from poles... so it is natural for ice to break off on the edges. Its warmer because its further away from poles.
These ice sheets can extend 40.. 50 miles into the sea. And we all know weather and climate changes significantly with those distances.
