Front

What is Arctic (or polar) amplification?

Back

The phenomenon that temperature near the poles is increasing at a higher rate than at lower latitudes.

Front

How do human activities contribute to climate change?

Back

Human activities lead to climate change and global warming because there are MORE greenhouse gases in the atmosphere and the temperature is increasing.

Front

What effect do warming seas have on storms?

Back

Warming seas will increase the number of storms.

Front

What is the primary reason for the increase in Earth's average temperature over the past century?

Back

Higher levels of carbon dioxide in the atmosphere.

Front

What is a consequence of melting permafrost?

Back

The melting of permafrost releases greenhouse gases, which increases warming.

Front

Define greenhouse gases.

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm.

Front

What role do oceans play in climate regulation?

Back

Oceans absorb carbon dioxide and heat, helping to regulate the Earth's climate.

Front

What is the significance of carbon dioxide in climate change?

Back

Carbon dioxide is a major greenhouse gas that contributes to global warming.

Front

Explain the term 'climate feedback.'

Back

Climate feedback refers to processes that can either amplify or diminish the effects of climate change.
