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.
Together, this background suggests that the majority of individuals who are diagnosed with the disease are likely to live with it for at least 20 years (if diagnosed at age 50) and potentially as long as 55 years (if diagnosed at age 20).
