Climate Change

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, which leads to an increase in global temperatures.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that contribute to the greenhouse effect by absorbing infrared radiation. Key examples include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

How does carbon dioxide contribute to global warming?

Back

Carbon dioxide traps heat in the atmosphere, leading to an increase in global temperatures, which is a primary driver of climate change.

Front

What human activities release greenhouse gases?

Back

Human activities such as burning fossil fuels (coal, oil, and natural gas), deforestation, and industrial processes release significant amounts of greenhouse gases into the atmosphere.

Front

What is the role of methane in climate change?

Back

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

Front

What is the impact of deforestation on climate change?

Back

Deforestation reduces the number of trees that can absorb carbon dioxide, leading to higher levels of CO2 in the atmosphere and contributing to climate change.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, and oceans. It is crucial for regulating Earth's climate and supporting life.

Front

What are the consequences of climate change?

Back

Consequences of climate change include rising sea levels, more extreme weather events, loss of biodiversity, and impacts on agriculture and human health.

Front

What is global warming?

Back

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