Human Activities and Climate Change

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat. They include 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 from the sun in the Earth's atmosphere, keeping the planet warm enough to support life.

Front

How do human activities contribute to climate change?

Back

Human activities, such as burning fossil fuels, deforestation, and industrial processes, increase the levels of greenhouse gases in the atmosphere, leading to climate change.

Front

What is global warming?

Back

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities and the greenhouse effect.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, including coal, oil, and natural gas, that are burned for energy.

Front

What is renewable energy?

Back

Renewable energy comes from sources that are naturally replenished, such as solar, wind, hydroelectric, and geothermal energy.

Front

What is energy efficiency?

Back

Energy efficiency is using less energy to provide the same service or achieve the same result, reducing energy waste.

Front

What role do forests play in climate change?

Back

Forests absorb carbon dioxide from the atmosphere, helping to reduce greenhouse gas levels and mitigate climate change.

Front

What is carbon footprint?

Back

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

Front

What are some effects of climate change?

Back

Effects of climate change include rising sea levels, more extreme weather events, loss of biodiversity, and changes in agricultural productivity.
