Detailed explanation-1: -Carbon dioxide (CO2) is a greenhouse gas. This means that it causes an effect like the glass in a greenhouse, trapping heat and warming up the inside.

Detailed explanation-2: -increased atmospheric carbon dioxide levels reduce the amount of heat radiating into space from Earth, causing Earth’s climate to warm. (Correct! Carbon dioxide causes global warming via the greenhouse effect, which occurs when greenhouse gases trap heat in Earth’s atmosphere.

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: -Since carbon dioxide also efficiently emits heat, any heat captured by carbon dioxide sooner escapes to space than it finds another molecule to absorb it. As a result, an increase in greenhouses gases like carbon dioxide means more heat is lost to space-and the upper atmosphere cools.

Detailed explanation-5: -CO2 traps heat and does not allow it to escape into space. As a result, the average temperature of the earth’s atmosphere is gradually increasing which results in global warming.
