Document Summary
Chapter 1 hw instructor rick di maio. Answer these questions with a brief response total time: 90 minutes: define radiative forcing and climate positive and negative feedback. Radiative forcing refers to an imbalance that develops at the top of the atmosphere between the amount of incoming radiation from the sun and outgoing radiation form the earth. The sun and earth"s natural reflectivity (albedo) are the two most important factors in radiative forcing. Climate positive feedback is when the earth allows more radiation from the sun coming in. Meaning, that changes in the earth"s reflectivity decreases and the earth absorbs more energy from the sun. Negative feedback is when the earth"s reflectivity increases meaning the earth does not absorb as much energy from the sun and it is reflected back into space: provide an example of climate positive feedback and climate negative feedback.
