A dialogue of sorts, poetic and to the images of Michael E. Mann's series on Climate Science.

Video Clip #1: This video clip should discuss Feedback Mechanisms. Positive feedback is one that multiplies the forcings. For example, the water vapour feedback; a warmer atmosphere can hold more water vapour. Since water vapour is a potent greenhouse gas, this leads to further warming, this is one of the largest positive feedback systems in the earth's climate system. The Ice Albedo Feedback is another important feedback system within the climate system. As the surface of the earth warms there is less snow and ice. This leads to less reflection and greater absorption of that incoming shortwave solar radiation (heat). This is another important positive feedback. Cloud Radiative Feedbacks and can be both positive and negative. For example, if a warmer atmosphere happens to produce more low clouds, the primary impact of this greater cloud cover would be to reflect more solar radiation (heat) hour to space and would be a cooling effect and would therefore be negative feedback. On the other hand, if a warmer atmosphere produces more high clouds, like cirrus clouds the primary impact of these thin high clouds is to increase the greenhouse effect due to their ability to trap much of the outgoing longwave terrestrial radiation but they will remain transparent to incoming shortwave radiation. That would be positive feedback.

Video Clip #2: This video clip should discuss how activities such as fossil fuel burning do not regulate the concentration of the greenhouse gases such as carbon dioxide but instead govern the atmospheric emissions which interact with the climate system.

Video Clip #3: This video clip should discuss how the ocean and the terrestrial biosphere and the marine biosphere - life on earth, all interact with the atmosphere in what is known as the global carbon cycle. For our purposes what is important here is when we put carbon dioxide into the atmosphere, by burning fossil fuels, at least some of that carbon dioxide has been absorbed by the climate system. Either by trees and forests on land or by marine life like plankton and algae in the ocean and it turns out that the ocean, the marine biosphere and the terrestrial biosphere have been absorbing nearly half the CO2 that we’ve been putting into the atmosphere. That leads to CO2 concentrations that have not increased as rapidly as we would have expected if all the carbon dioxide remained in the atmosphere.
