Consequences of Global Warming: Ecosystems at Risk

The video discusses the greenhouse effect and its role in maintaining Earth's temperature balance. It highlights the impact of fossil fuel emissions on climate change, leading to increased carbon dioxide levels, ocean acidification, and rising sea levels. The effects on marine life, melting ice, and ecosystems are explored, emphasizing the interconnectedness of Earth's systems. The video concludes with a review and questions to reinforce learning.

What is a potential effect of losing the Arctic ice cap?

• Colder winters in Europe

• More hurricanes in Asia

• More droughts in North America

• Increased rainfall in North America

What is a significant threat to low-lying coastal areas due to climate change?

• More frequent earthquakes

• Rising sea levels
