Why are greenhouse gases bad for the atmosphere?

The right balance of greenhouse gases in the atmosphere provides a steady climate on Earth. It offers a habitable space to all living things. While the atmosphere retains a certain amount of radiation from the sun by itself, greenhouse gases help the Earth trap solar energy and keep heat close to the surface. This heat retention mechanism is called the greenhouse effect.

However, this balance has been distorted by human activity, and subsequently, the greenhouse effect has been increased. Emissions of carbon dioxide, methane and nitrous oxide have skyrocketed in the past century, and there is more heat trapped in the atmosphere. Because of this overly enhanced greenhouse effect, the Earth’s temperature has risen. This increase in temperature has caused negative environmental impacts.
