Greenhouse Effect

The greenhouse effect refers to the process by which certain gases in the Earth’s atmosphere trap and retain heat from the sun, leading to a warming effect on the planet’s surface. These gases, known as greenhouse gases, include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor. The greenhouse effect is essential for sustaining life on Earth, as it helps to maintain an average surface temperature of about 15°C (59°F), enabling the existence of liquid water and supporting a diverse range of ecosystems. However, human activities, particularly the burning of fossil fuels and deforestation, have significantly increased the concentration of greenhouse gases in the atmosphere. This enhanced greenhouse effect, often referred to as anthropogenic or human-induced climate change, is causing the Earth’s climate to warm at an accelerated rate, leading to a range of environmental impacts such as rising sea levels, more frequent extreme weather events, and changes in ecosystems.
