Detailed explanation-1: -The greenhouse effect is a good thing. It warms the planet to its comfortable average of 57 degrees Fahrenheit (13.9 degrees Celsius) and keeps life on earth, well, livable. Without it, the world would be a frozen, uninhabitable place, more like Mars.

Detailed explanation-2: -Total radiative forcing is dominated by the positive radiative forcing of carbon dioxide. Methane and ozone also contribute positive radiative forcings.

Detailed explanation-3: -The greenhouse effect is the way in which heat is trapped close to Earth’s surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.

Detailed explanation-4: -The Short Answer: The greenhouse effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.
