I know there are many different trails, Distrails, Vapor trails, Contrails and Chemtrails and more.

Maybe you're better off going to a pro-chemtrail forum to post your pictures where everyone will pat you on the back for being so open minded.
Many facets of the earth's climatic system are poorly understood. A significant uncertainty associated with the modeling of future climatic changes is due to deficiencies in the understanding of, and in the incorporation into the climate models of, several interactive climate feedback mechanisms. In this discussion of radiative forcing, the planet's heat balance, and these feedbacks and their consequences, emphasis is given to global mean quantities, since, conventionally, the concept of radiative feedback mechanisms is applied to global mean quantities associated with changes from one equilibrium climate to another. Many aspects of these feedback mechanisms are controversial. The conventional wisdom has been challenged on several pointsTo date, most emphasis has been placed on the development and testing of atmospheric models. Even though policymakers' would like them, current capabilities do not allow credible projections of regional effects. The panel finds that these and other aspects of climate models have even greater uncertainty than those associated with global mean temperature projections. However, for purposes of assessing their limits for policy decisions, the primary focus of the examination here is on global mean temperature. Considerable effort has been focused on atmospheric GCM experiments in which the CO2 concentration of the atmosphere is instantaneously doubled and the models are then allowed to achieve a new equilibrium climate. Although these simulations do not provide information on time-dependent (or "transient") climatic changes that would accompany more realistic greenhouse gas. For present purposes the only simulations considered are those that utilize computed clouds; i.e., that incorporate cloud feedback. accumulation scenarios, they do allow a means of testing, understanding, and comparing atmospheric GCMs. books.nap.edu...
