| How is Human Activity affecting the Composition of Air? | -More Humans = More Respiration = More Carbon Dioxide. Simple
-More Humans also mean more Energy is needed for their Modern Lives, like Heating and Cooking. Lifestyles also are Changing, in a Better-Off Way. This means, from an Individual Aspect, more Energy is being used per Person.
-And most of the Energy comes from Fossil Fuels, which releases Carbon Dioxide
-More People also means more Land is Needed, so Deforestation takes place for Housing which Decreases Carbon Dioxide and Water Vapor Absorption, and Decreases Oxygen Levels. |
| How has the Level of Carbon Dioxide Changed from 1700 to 2020? | -In the 1700, the Carbon Dioxide Levels was around 0.028%
-In 1850, the Level began Rapidly Increasing due to the Industry Revelation [Percentage here was around 0.029%]
-In 1950, it became 0.031%
-in 2020, it became 0.040%
-Keep in mind it took Millions of Years for it to become 0.028, and it was Constant, and it took only 300 to almost Double it |
| What exactly is the Green House Effect? | -First Step is knowing the Sun gives out EM Radiation
-Most of the Wavelengths can Pass through the Atmosphere, like IR
-EM Radiation that has Short Wavelengths is Absorbed by the Earth - this Warms it Up
-Then, the Earth Radiates some of that Heat that it Absorbed as Infrared Radiation
-This is either Absorbed by the Greenhouse Gases, Transmitted into Space or is 'Bounced' back towards Earth
-If its Absorbed and Bounced Back [Re-Emission] then it makes the Earth Warm. This is the Green House Effect |
| So what happens if the Greenhouse Gases Concentration Increased? What even are Greenhouse Gases? | -If this Concentration Increased, then that means more Heat Radiation is Absorbed, and Less is Transmitted to Space. This makes the Atmosphere Heat up More
-Carbon Dioxide, Water Vapor and Methane are 3 Main Greenhouse Gases |
