What is the Greenhouse Effect?

The Greenhouse Effect refers to the warming of Earth’s atmosphere as a result of the accumulation of greenhouse gases, such as carbon dioxide, methane, and water vapor. These gases trap heat from the sun, preventing it from escaping back into space. As solar energy reaches the Earth, some of it is reflected back into space, but the greenhouse gases absorb and re-radiate a portion of it, effectively warming the atmosphere. This effect is essential for maintaining temperatures that support life on Earth, but human activities that increase the concentration of these gases can lead to enhanced greenhouse effect, contributing to climate change.

In contrasting aspects of this concept, the cooling of the atmosphere due to pollution, solar radiation reflection, and climate alterations from volcanic activity do not accurately encapsulate the role and mechanism of the greenhouse effect, which primarily underscores the heating impact of greenhouse gas accumulation in the atmosphere.
