What is the atmosphere?

Back

The atmosphere is a layer of gases surrounding the Earth, essential for life, providing oxygen, regulating temperature, and protecting from harmful solar radiation.

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), contributing to the greenhouse effect.

What is the Kyoto Protocol?

Back

The Kyoto Protocol is an international treaty that commits its parties to reduce greenhouse gas emissions, based on the premise that global warming exists and human-made CO2 emissions have caused it.

What are feedback loops in climate systems?

Back

Feedback loops are processes that can either amplify (positive feedback) or diminish (negative feedback) the effects of climate change, such as the melting of ice reducing albedo and increasing warming.

What is the impact of deforestation on climate change?

Back

Deforestation contributes to climate change by increasing carbon dioxide levels in the atmosphere, as trees that absorb CO2 are removed.

What is the role of oceans in climate regulation?

Back

Oceans absorb a significant amount of CO2 and heat, helping to regulate the Earth's climate, but they can also become warmer and more acidic due to climate change.
