What is global warming?

Back

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

Front

What is the greenhouse effect?

Back

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

Front

Why is the natural greenhouse effect important?

Back

The natural greenhouse effect is essential for maintaining temperatures that allow life to exist on Earth.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

What is the primary greenhouse gas responsible for human-caused global warming?

Back

Carbon dioxide (CO2) is the primary greenhouse gas responsible for human-caused global warming.

Front

How can we reduce global warming?

Back

We can reduce global warming by using energy more efficiently, shifting to renewable resources, reducing deforestation, and slowing population growth.

Front

What role does deforestation play in global warming?

Back

Deforestation contributes to global warming by reducing the number of trees that can absorb CO2, increasing the amount of greenhouse gases in the atmosphere.

Front

What is the impact of methane on global warming?

Back

Methane is a potent greenhouse gas that is significantly more effective than CO2 at trapping heat in the atmosphere, contributing to global warming.

Front

How do polar ice caps provide evidence of past climate?

Back

Polar ice caps contain layers of ice that trap air bubbles, preserving a record of Earth's past atmosphere and climate conditions.

Front

What is the significance of renewable resources in combating global warming?

Back

Renewable resources, such as solar and wind energy, produce little to no greenhouse gas emissions, making them crucial for reducing global warming.
