Climate Change and Energy Budget Flashcard

Front

What is the primary cause of the increasing concentration of carbon dioxide in the atmosphere?

Back

Industrial emissions are the primary cause of the increasing concentration of carbon dioxide in the atmosphere.

Front

Why is the tropical climate warmer than the climate at the north and south poles?

Back

The tropical climate is warmer due to the angle of solar radiation, which is more direct compared to the poles.

Front

What is the effect of sea ice on warming due to increased greenhouse gases?

Back

Sea ice enhances warming through a process called positive feedback, as it is highly reflective and its reduction leads to more solar radiation absorption by the ocean.

Front

What would the theoretical global average temperature be without the greenhouse effect?

Back

Without the greenhouse effect, the theoretical global average temperature would be -17°C.

Front

What prevents the tropics from getting hotter and the poles from getting colder?

Back

The circulation of the Earth's atmosphere and oceans prevents the tropics from getting hotter and the poles from getting colder.

Front

Define greenhouse gases.

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat, such as carbon dioxide, methane, and water vapor.

Front

What is the greenhouse effect?

Back

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

Front

What role do oceans play in the Earth's energy budget?

Back

Oceans absorb, store, and redistribute solar energy, playing a crucial role in regulating the Earth's climate.

Front

Explain the concept of positive feedback in climate change.

Back

Positive feedback in climate change occurs when a change in the climate system causes further changes that amplify the initial effect, such as melting ice reducing reflectivity and increasing warming.

Front

What is deforestation and how does it contribute to climate change?

Back

Deforestation is the clearing of forests, which contributes to climate change by increasing carbon dioxide levels in the atmosphere as trees that absorb CO2 are removed.
