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.
Left without treatment, the majority of people infected with HIV will develop signs of HIV-related illness within 5â10 years, although this can be shorter. The time between acquiring HIV and an AIDS diagnosis is usually between 10â15 years, but sometimes longer.
