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.

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect. Major greenhouse gases include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, thus warming the planet.

Front

What is deforestation?

Back

Deforestation is the permanent clearing and repurposing of land that was once forested, often for agriculture, urban development, or logging.

Front

What causes ice ages?

Back

Ice ages can be caused by various factors, including changes in Earth's tilt or orbit, volcanic activity, and variations in solar radiation.

Front

What is urbanization?

Back

Urbanization is the process by which an increasing percentage of a population lives in urban areas, often leading to the growth of cities.

Front

What are ice cores?

Back

Ice cores are cylindrical samples taken from ice sheets or glaciers that contain layers of ice, which can provide valuable information about past climates.

Front

Why do scientists study ice cores?

Back

Scientists study ice cores to analyze trapped gases and particles, which helps them understand past climates and atmospheric conditions.

Front

What is the impact of climate change on sea levels?

Back

Climate change leads to rising sea levels due to the melting of ice caps and glaciers, as well as the thermal expansion of seawater as it warms.

Front

What is carbon footprint?

Back

A carbon footprint is the total amount of greenhouse gases emitted directly or indirectly by an individual, organization, event, or product, usually measured in carbon dioxide equivalents.
