Detailed explanation-1: -By adding more carbon dioxide to the atmosphere, people are supercharging the natural greenhouse effect, causing global temperature to rise.

Detailed explanation-2: -When there’s more CO2 in the atmosphere, it makes the atmosphere warmer by trapping heat. Since humans are adding more CO2 to the atmosphere, that helps explain why temperatures are increasing around the world.

Detailed explanation-3: -Increased level of carbon dioxide in the atmosphere traps the heat rays reflected by the earth causing an increase in the temperature on the earth.

Detailed explanation-4: -Dramatic new findings from two climate science professors suggest that an increase in carbon dioxide in the atmosphere follows a rise in temperature rather than coming before it and causing it, throwing into doubt the whole of the current theory of human-driven global warming.

Detailed explanation-5: -When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down.]
