The Greenhouse Effect is a natural process where certain gases in Earth’s atmosphere trap heat, preventing it from escaping into space. These gases, like carbon dioxide (CO2), methane (CH4), and water vapor (H2O), absorb and re-emit infrared radiation, warming the planet’s surface. Without the greenhouse effect, Earth would be too cold to sustain life. However, human activities, particularly the burning of fossil fuels, have increased the concentration of these gases, leading to enhanced global warming.
