The Impact of Greenhouse Gases on Climate Change

1. What are greenhouse gases?

Options:

A. Gases released from factories
B. Gases that trap heat in the atmosphere
C. Gases found in greenhouses

2. How do greenhouse gases contribute to global warming?

Answer:

Explanation:

Greenhouse gases are gases that trap heat in the Earth's atmosphere, leading to the greenhouse effect. These gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases.

Greenhouse gases are essential for maintaining Earth's temperature, but human activities, such as burning fossil fuels and deforestation, have increased the concentration of these gases in the atmosphere. As a result, more heat is trapped, causing global temperatures to rise.

Carbon dioxide is the most prevalent greenhouse gas emitted through human activities. It is released from vehicles, power plants, and industrial processes. Methane, a potent greenhouse gas, is produced by livestock, landfills, and natural gas operations. Nitrous oxide comes from agricultural practices and industrial activities.

The accumulation of greenhouse gases in the atmosphere leads to climate change, resulting in more frequent and severe heatwaves, droughts, floods, and extreme weather events. It also contributes to the melting of polar ice caps and rising sea levels, endangering coastal communities.

To mitigate the impact of greenhouse gases on climate change, it is crucial to reduce emissions by transitioning to renewable energy sources, improving energy efficiency, and adopting sustainable land use practices. International cooperation and policies are essential to address this global challenge and safeguard the planet for future generations.
