What is Global Climate Change?

Back

Global Climate Change refers to long-term changes in temperature, precipitation, wind patterns, and other elements of the Earth's climate system, primarily caused by human activities such as burning fossil fuels and deforestation.

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat. The main greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.

Front

How do greenhouse gases contribute to climate change?

Back

Greenhouse gases trap heat in the lower atmosphere, preventing it from escaping into space, which leads to an increase in Earth's average temperature.

Front

What is methane and why is it significant in climate change?

Back

Methane is a potent greenhouse gas that is significantly more effective at trapping heat in the atmosphere than carbon dioxide, making it a major contributor to climate change.

Front

What human activities increase greenhouse gas emissions?

Back

Human activities such as burning fossil fuels for energy, deforestation, industrial processes, and agricultural practices increase greenhouse gas emissions.

Front

What is the impact of deforestation on climate change?

Back

Deforestation reduces the number of trees that can absorb CO2, leading to higher concentrations of greenhouse gases in the atmosphere and contributing to climate change.

Front

What role does agriculture play in greenhouse gas emissions?

Back

Agriculture contributes to greenhouse gas emissions through practices such as livestock production (which emits methane) and the use of nitrogen-based fertilizers (which emit nitrous oxide).

Front

What is the significance of renewable energy in combating climate change?

Back

Renewable energy sources, such as wind and solar power, produce little to no greenhouse gas emissions compared to fossil fuels, making them crucial for reducing overall emissions.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, keeping the planet warm enough to support life.

Front

What are some ways to reduce greenhouse gas emissions?

Back

Ways to reduce greenhouse gas emissions include using renewable energy, improving energy efficiency, reducing meat consumption, and increasing forest cover.
