In Section 1.1 it was mentioned that $280 \mathrm{~km}^3$ of ice was being melted each year in the Arctic. Assume when all the ice is melted that the energy required to melt the ice now can be used to heat the atmosphere, how many ${ }^{\circ} \mathrm{C}$ will the atmosphere increase in temperature each year? Note the heat capacity of air is remarkably independent of pressure until extremely low pressure and can be assumed constant for the purposes of this calculation.

Key Concepts

Latent Heat of Fusion

This concept refers to the amount of energy required to change a substance from a solid to a liquid at its melting point without changing its temperature. It is critical in calculations involving phase transitions, as it determines how much energy is needed for the melting process.

Volume-to-Mass Conversion

When dealing with a given volume of material, such as ice, it is necessary to convert this volume to mass using the density of the substance. This conversion is essential to quantify energy transfer in terms of mass-dependent properties.

Specific Heat Capacity

The specific heat capacity is the amount of energy needed to raise the temperature of one unit mass of a substance by one degree. This property is crucial for understanding how much the temperature of a substance, like air, will increase when it absorbs a given amount of energy.

Energy Conservation in Heating

This concept involves applying the principle of energy conservation to relate the energy released during one process (such as melting ice) to the energy absorbed to increase the temperature of another system (such as the atmosphere). It provides the framework for calculating temperature change from energy input.
