The significance of the greenhouse effect on Earth's climate primarily lies in its role in regulating temperature. Certain gases, known as greenhouse gases (such as carbon dioxide and methane), trap heat in the atmosphere, maintaining temperatures conducive to sustaining life. While the greenhouse effect is a natural phenomenon essential for life, human activities—especially the burning of fossil fuels—have intensified its impact, leading to global warming and climatic changes. Understanding this effect is vital for developing strategies to mitigate climate change and promote environmental sustainability.
