Water's specific heat is 4.184 J/g degrees Celcius. Although the ocean is salt water, its specific heat is relatively the same as pure water, and for the last century the temperature of the world's oceans have collectively increased by 2.0 degrees Celcius. If the specific heat of ocean water was instead 2.092 J/g degrees Celcius, what would you expect the total temperature change of the ocean to be over the last century? Explain your reasoning.
