What is a Positive Feedback Loop?

Back

A Positive Feedback Loop is a process that amplifies or accelerates changes in a system, leading to an increase in the effect of the initial change.

Front

What is a Negative Feedback Loop?

Back

A Negative Feedback Loop is a process that counteracts changes in a system, promoting stability by reducing the effect of the initial change.

What does Albedo refer to?

Back

Albedo is the measure of how much light that hits a surface is reflected without being absorbed. It is a key factor in Earth's energy balance.

Front

What is Earth's Energy Budget?

Back

Earth's Energy Budget refers to the balance between the energy Earth receives from the sun and the energy it radiates back into space.

Front

How does a Positive Feedback Loop affect global warming?

Back

A Positive Feedback Loop can exacerbate global warming by increasing the effects of warming, such as ice melting, which reduces albedo and leads to further warming.

Front

How does a Negative Feedback Loop help stabilize the climate?

Back

A Negative Feedback Loop helps stabilize the climate by reducing the effects of warming, such as increased cloud cover reflecting sunlight and cooling the Earth.

Front

What is an example of a Positive Feedback Loop in climate change?

Back

An example is the melting of polar ice, which decreases albedo, leading to more heat absorption and further ice melt.

Front

What is an example of a Negative Feedback Loop in climate change?

Back

An example is increased cloud formation due to evaporation, which reflects sunlight and can lead to cooling.

Front

What role does the greenhouse effect play in Earth's energy budget?

Back

The greenhouse effect traps heat in the atmosphere, affecting the balance of energy entering and leaving the Earth system.

Front

What happens to Earth's energy budget if more greenhouse gases are added?

Back

If more greenhouse gases are added, it can lead to an imbalance in Earth's energy budget, resulting in global warming.
