1. Human Impact on the Atmosphere
Notes Right Side

2. Air Pollution
-Air pollution is the contamination of the atmosphere by pollutants from humans and natural sources
-Natural air pollutants include volcanoes, wildfires, and dust storms
-Humans main pollutant is burning fossil fuels with cars and factories
-There are 2 types of air pollutants gases and particulates
-Gases include carbon monoxide, sulfur dioxide, nitrogen dioxide, etc.
-Particulates are tiny particles that are solid that are suspended in the air

3. Humans affect on the air
-The Greenhouse effect is the way by which certain gases absorb and reradiate thermal energy
-Greenhouse gasses are what cause this to happen and humans have caused a dramatic rise in these gases
-37% more CO2 than in the 1700’s
-The Ozone which protects us from Ultraviolet rays is thinning
-Increase in acidity of rain
-can kill off aquatic organisms and change ecosystems
-Smog in large cities can cause lung damage

4. Impact on Humans
-Air quality is the measure of how clean or polluted the air is
-Measured by Air Quality Index and the higher the number the worse the air
-Daily exposure to small amounts of air pollution can cause serious health problems
-Short Term: Coughing, Headaches, Difficulty breathing
-Long Term: Asthma, Emphysema, Allergies, and Lung Cancer
-Global temperatures are expected to rise degrees Celsius by 2100
-This will cause a rise in the water levels
-This could destroy areas that people currently live
