Answer:
C. Average temperatures would increase.
Step-by-step explanation:
If radiative forcing increases in a portion of the earth, the average temperature over that area would increase.
There is a direct proportionality between temperature and radiative forcing.
Radiative forcing is aslo know as climate forcing. It is defined as the differences between the sunlight absorbed or insolation and the part radiated back.
Incoming solar radiation can be absorbed, reflected or diffused. When solar radiation is absorbed on the earth surface, it warms the surface and heating occurs. This makes temperature rises. When it reflects, it goes back and does not change temperature significantly.
Radiative forcing is also known as climate forcing. The higher the differences between absorbed radiation and the component reflected the higher the radiative forcing and the more temperature rises.
If radiative forcing is low, more radiation is reflected and the temperature is not affected for much.
Radiative forcing is a key aspect of climate change debates and other climatic discuss.
