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.
It's the virus that causes AIDS, acquired immune deficiency syndrome. Someone with HIV can get sick from things that don't usually affect people, and people with AIDS tend to get certain uncommon diseases and illnesses. Anyone can get HIV. Both men and women can spread HIV. A person with HIV can feel OK and still give the virus to others. According to the CDC, about 1.2 million people in the U.S. are living with the HIV infection, and there are about 50,000 new HIV infections each year. Having HIV does not always mean that you have AIDS. It can take many years for people with the virus to develop AIDS.
