Greenhouse gases can be removed from the atmosphere by various processes, as a consequence of: 1  a physical change (condensation and precipitation remove water vapor from the atmosphere). 2  a chemical reaction within the atmosphere. 3  a physical exchange between the atmosphere and the other compartments of the planet.
What we can say is that the vast majority of people infected with HIV will develop AIDS sometime during their life (an average of 10 years or more after infection), and with early intervention and treatment, they could potentially live with AIDS for many years more.
How long can or does the HIV virus remain dormant in the Human Body before it becomes AIDS virus? For the majority of patients who have HIV, the dormancy period lasts about 10 years. About 10 percent to 20 percent of patients progress to having AIDS within 5 years. It is estimated that another 5 percent to 10 percent of patients will not reach the AIDS phase for more than 15 years.
