average) covered by pack-ice in the months and latitudes in question. The figure suggests that when 

 the sea becomes free of ice in the early summer, the rise in temperature (December-January) is more 

 rapid in high than in low latitudes. Here again, however, the curves can only be taken as a rough 

 indication of the rise and fall of temperature.
