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.
People who have HIV and donât get treatment almost always die from the virus. But with medication, people with HIV can be healthy and live a long time. Whatâs the difference between HIV and AIDS? HIV is the virus that causes AIDS. AIDS stands for Acquired Immune Deficiency Syndrome. HIV and AIDS are not the same thing. And people with HIV do not always have AIDS. HIV is the virus thatâs passed from person to person. Over time, HIV destroys an important kind of the cell in your immune system (called CD4 cells or T cells) that helps protect you from infections. When you donât have enough of these CD4 cells, your body canât fight off infections the way it normally can.
