Climate change causes and impacts

Front

What is climate change?

Back

Climate change refers to significant and lasting changes in the Earth's climate, particularly an increase in temperature due to human activities, primarily the burning of fossil fuels.

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect. Major greenhouse gases include carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O).

How did the Industrial Revolution contribute to climate change?

Back

The Industrial Revolution contributed to climate change by accelerating greenhouse gas release through increased fossil fuel consumption.

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, preventing it from escaping into space and thus warming the planet.

What is albedo?

Back

Albedo is the measure of how much sunlight is reflected by a surface. Surfaces with high albedo, like ice, reflect more sunlight, while darker surfaces absorb more.

What is a positive feedback mechanism in climate change?

Back

A positive feedback mechanism amplifies changes in the climate system. For example, melting ice reduces albedo, leading to more heat absorption and further ice melt.

What is a criticism of climate treaties?

Back

A common criticism of climate treaties is that they are not legally binding, which can lead to insufficient commitment from countries.

What is the impact of climate change on agriculture?

Back

Climate change can lead to shifts in growing areas, affecting where certain crops can be cultivated due to changing temperature and precipitation patterns.

What role do ocean currents play in climate?

Back

Ocean currents help regulate the Earth's climate by distributing heat around the planet, influencing weather patterns and temperatures.

What is the significance of carbon dioxide in climate change?

Back

Carbon dioxide (CO₂) is a major greenhouse gas released through human activities, such as burning fossil fuels, and is a key driver of climate change.
