What is climate change?

Back

Climate change refers to significant and lasting changes in the Earth's climate, particularly an increase in temperature due to human activities such as burning fossil fuels.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat, including carbon dioxide (CO2), methane (CH4), and water vapor.

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 is global warming?

Back

Global warming is the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases.

Front

What are some effects of climate change?

Back

Effects of climate change include increased temperatures, rising sea levels, more extreme weather events, and changes in precipitation patterns.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of carbon dioxide and water, releasing oxygen as a byproduct.

Front

What role do forests play in climate change?

Back

Forests act as carbon sinks, absorbing carbon dioxide from the atmosphere and helping to mitigate climate change.

Front

What is a positive feedback loop in climate change?

Back

A positive feedback loop in climate change occurs when an initial change causes further changes that amplify the original effect, such as increased evaporation leading to more water vapor and further warming.

Front

What is a negative feedback loop in climate change?

Back

A negative feedback loop in climate change occurs when an initial change triggers processes that counteract the change, helping to stabilize the system.

Front

What are renewable energy sources?

Back

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