What would be the temperature of the north pole iff the ice melted?
If the ice at north or south pole has just melted and no further energy has been supplied then the temperature will remain 0 degree C. its because when ther ice is melting the heat supplied doesn’t increases the temperature of the ice body but is consumed as energy required to melt down its solid structure.you may have heard about Latent heat in thermodynamics(chapters related to heat). If more energy is supplied then it will be more than zero celsius depending on the quantity of water present there.
