The forcing term in relation to earth's climate system is radiative forcing or climate forcing.It ia the difference between the amount of insolation(sunlight) absorbed by earth and the the amount it radiated back to space.If the amount of sunlight absorbed by earth is more ,then their occurs positive climate forcing.Positive climate forcing creates warming and it will warm the earth.If the amount of sunlight radiated back to space is more than that it is receiving then their occurs negative climate forcing.Negative climate forcing cools down earth.If their is thermal equilibrium then radiative forcing is zero.

Many cities are implementing rent control due to rapidly escalating rents, forcing long term renters out of their housing. Using supply and demand analysis, explain what happens to the market for rental housing in these cities. What will happen to the available housing in these cities versus the demand for housing? Who gains and who loses? What other options are available to solve housing shortages? How might they affect the available supply of rental housing?
