Short introductory paragraph on Greenhouse Effect – World Geography
The Greenhouse Effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth, some of it is reflected back to space, and the rest is absorbed and re-radiated by greenhouse gases in the atmosphere. This retained heat keeps the Earth’s temperature at a level suitable for life. However, human activities, such as burning fossil fuels and deforestation have increased the concentration of greenhouse gases, intensifying the greenhouse effect and contributing to global warming and climate change.
