Climate Change and Greenhouse Gases

Front

What is climate change?

Back

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

Front

What are greenhouse gases?

Back

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

Front

What is the greenhouse effect?

Back

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

Front

What evidence do we have that the climate is changing?

Back

Increased global temperatures, melting glaciers and arctic ice, and rising sea levels are all evidence that the climate is changing.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient organisms, including oil, coal, and natural gas, used as energy sources.

Front

How do fossil fuels contribute to climate change?

Back

Burning fossil fuels releases carbon dioxide and other greenhouse gases into the atmosphere, contributing to global warming.

Front

What is the relationship between CO2 emissions and global temperatures?

Back

As carbon dioxide concentrations increase, global temperatures tend to increase, indicating a direct relationship.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

Front

What is the role of glaciers in climate change?

Back

Glaciers act as indicators of climate change; their melting contributes to rising sea levels and reflects changes in global temperatures.

Front

What are alternative fuels?

Back

Alternative fuels are energy sources that can replace fossil fuels, such as solar, wind, and biofuels, and are generally more environmentally friendly.
