The Greenhouse Effect and Climate Change
Read the text and answer the questions.
The greenhouse effect is a natural process that helps keep the Earth warm enough to
support life. It occurs when certain gases in the atmosphere, like carbon dioxide (CO₂),
methane (CH₄), and water vapor, trap heat from the sun. These gases act like the glass
of a greenhouse, allowing sunlight to enter but preventing some of the heat from
escaping back into space. Without the greenhouse effect, the Earth would be too cold
for most living things to survive.
How Does the Greenhouse Effect Work?
1. Sunlight Reaches Earth : The sun sends energy to Earth in the form of light and
heat. Some of this energy is absorbed by the Earth's surface, warming the planet.
2. Heat is Reflected : Some of the heat is reflected back toward space.
3. Greenhouse Gases Trap Heat : Greenhouse gases absorb much of this reflected
heat and radiate it back to the Earth's surface, keeping the planet warm.
This natural process keeps the Earth’s temperature stable. However, human activities
are making this process stronger, leading to global warming.
What is Climate Change?
Climate change refers to significant and long-lasting changes in Earth’s weather
patterns and temperatures. While climate change has occurred naturally throughout
history, human activities have accelerated it in recent years. Burning fossil fuels like
coal, oil, and gas releases large amounts of greenhouse gases, increasing the Earth's
temperature.
Impacts of Climate Change
1. Rising Temperatures : Global temperatures are increasing, leading to heatwaves,
droughts, and wildfires.
2. Melting Ice and Rising Seas : Ice in the Arctic and Antarctic is melting, causing sea
levels to rise and threatening coastal communities.
3. Extreme Weather : Climate change causes stronger storms, heavier rainfall, and
unpredictable weather patterns.
4. Harm to Ecosystems : Many plants and animals struggle to adapt to changing
conditions, leading to habitat loss and extinction.
How Can We Slow Climate Change?
1. Use Renewable Energy : Switching to solar, wind, and hydropower reduces the
need for fossil fuels.
2. Plant Trees : Trees absorb carbon dioxide, helping to reduce greenhouse gases in
the atmosphere.
3. Conserve Energy : Turning off lights, using energy-efficient appliances, and
carpooling can lower emissions.
4. Reduce, Reuse, Recycle :Managing waste responsibly helps reduce pollution.
