Detailed explanation-1: -Certain gases in the atmosphere absorb energy, slowing or preventing the loss of heat to space. Those gases are known as “greenhouse gases.” They act like a blanket, making the earth warmer than it would otherwise be. This process, commonly known as the “greenhouse effect, ” is natural and necessary to support life.

Detailed explanation-2: -Much of this infrared radiation does not reach space, however, because it is absorbed by greenhouse gases in atmosphere, and is then emitted as infrared radiation back toward the Earth’s surface. This process is known as the greenhouse effect.

Detailed explanation-3: -The greenhouse gases in the dry air in Earth’s atmosphere include carbon dioxide, methane, nitrous oxide, ozone, and chlorofluorocarbons. While making up around 0.05% of Earth’s total atmosphere, they play major roles in trapping Earth’s radiant heat from the Sun and keeping it from escaping into space.

Detailed explanation-4: -To get energy or electricity, we burn fossil fuels like coal, oil, and natural gas. This releases carbon dioxide and other greenhouses gases into the atmosphere. The more greenhouses gases we put into the atmosphere, the more heat they absorb-and the warmer our Earth becomes. This is called climate change .

Detailed explanation-5: -As CO2 soaks up this infrared energy, it vibrates and re-emits the infrared energy back in all directions. About half of that energy goes out into space, and about half of it returns to Earth as heat, contributing to the ‘greenhouse effect. ‘
