Climate change

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes.

Front

What are greenhouse gases (GHGs)?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat. They include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

How does deforestation contribute to climate change?

Back

Deforestation leads to increased carbon dioxide levels in the atmosphere because trees absorb CO2. When trees are cut down, this stored carbon is released, contributing to global warming.

Front

What is the impact of fossil fuel combustion on the environment?

Back

Burning fossil fuels releases greenhouse gases, particularly carbon dioxide, which contributes to air pollution and climate change.

Front

What are some alternatives to fossil fuels?

Back

Alternatives to fossil fuels include renewable energy sources such as solar, wind, hydroelectric, and geothermal energy.

Front

What role do electric vehicles play in reducing pollution?

Back

Electric vehicles produce zero tailpipe emissions, which helps reduce air pollution and greenhouse gas emissions compared to traditional gasoline-powered vehicles.

Front

How does food production contribute to climate change?

Back

Food production contributes to climate change through greenhouse gas emissions from agricultural practices, transportation, and processing.

Front

What is the significance of the atomic bombings in relation to climate change?

Back

The atomic bombings of Hiroshima and Nagasaki released large amounts of energy and pollutants into the atmosphere, contributing to environmental changes and climate effects.

Front

What is the relationship between population growth and climate change?

Back

Population growth increases demand for resources, leading to more energy consumption, waste production, and greenhouse gas emissions, exacerbating climate change.

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 waste, and promoting sustainable transportation.
