What is Climate Change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time. While climate change is a natural phenomenon, human activities have been a major driver of recent changes.

What is a positive feedback loop?

Back

It's when outputs from a system reinforce the current trajectory or trend of the system itself.

Why does Earth experience different seasons?

Back

The Earth's rotational axis points in different directions relative to the sun at different times of the year.

Front

How does the greenhouse effect work?

Back

Energy radiated from the Earth’s surface is absorbed by greenhouse gases in the atmosphere which re-radiate it, causing warming by slowing or preventing it from escaping into space.

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 nitrous oxide (N2O).

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate is the long-term average of weather patterns in a specific area.

Front

What role do oceans play in climate regulation?

Back

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

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms.

Front

What is deforestation and how does it affect climate change?

Back

Deforestation is the clearing of forests, which reduces the number of trees that can absorb CO2, contributing to increased greenhouse gas levels.

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.
