Water has a characteristically high specific heat, making it an important vector (or mechanism) for redistributing heat around the globe.
Specific heat can be defined as the quantity of heat required to raise the temperature of one gram of a substance by one degree Celsius. The units of specific heat are usually calories or joules per gram per degree Celsius.
The specific heat of water is 1 calorie (or 4.186 joules) per gram per degree Celsius. The incoming radiation from the sun is responsible for warming up the Earth. Water in particular, has a high heat capacity at 4.18 J/g*C, which indicates that more heat is needed to warm a gram of water. This is the reason that throughout a warm summer day, the water in the ocean does not experience a significant change.
