Climatic phenomenon

• Climate change is the disturbance in the climatic pattern or describes a change in the average condition in a region over a long period of time.
• Climate change is a natural phenomenon and has been occurring since the earth came into being.
• Climate change can be caused by nature and humans.
• Higher global temperature could result in a melting of polar ice caps, rise of sea and ocean levels, changes in ocean current, changes in weather patterns, extreme storms and cyclones, drought, forest and wildfire, and death of flora and fauna.
• A Greenhouse is a building with glass walls and a glass roof.
• Greenhouses are used to grow plants, such as tomatoes and tropical flowers.
• Greenhouse stays warm inside, even during winter.
• Sunlight shines into the greenhouse and warms the planet and air inside.
• Sunlight passes through the atmosphere and reaches the Earth’s surface.
• Sunlight gets absorbed by soil and other objects and is converted into heat.
• This heat is radiated back to the atmosphere.
• Molecules of carbon dioxide and water vapor absorb this heat, preventing it from escaping to outer space.
• The phenomenon of sunlight getting absorbed by the atmosphere and warming the earth's surface is known as the Greenhouse Effect.
• The Earth’s atmosphere is like a Greenhouse.
• Greenhouse Effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat.
• Carbon dioxide and water vapor, referred to as Greenhouse Gases, are gases in the earth’s atmosphere that trap heat.
• During the day, the sun shines through the atmosphere, warming the earth's surface.
• At night the earth's surface cools, releasing heat back into the air.
• Some of the heat is trapped by the greenhouse gases in the atmosphere.
• The greenhouse effect is good because it allows our atmosphere to hold heat, providing temperatures that support life on Earth.
• Without the greenhouse effect, our atmosphere would not be able to retain infrared light and would be incredibly cold, much like the surface of Mercury.
• High concentration of greenhouse gases enhances the greenhouse effect causing an atmospheric temperature higher than needed.
