Exploring the Carbon Cycle

The video explains global warming and its connection to the greenhouse effect, where gases like carbon dioxide trap heat in the atmosphere. It delves into the carbon cycle, highlighting how carbon is recycled through respiration and photosynthesis. The role of decomposers in breaking down dead matter and forming fossil fuels over millions of years is discussed. The video emphasizes the impact of burning fossil fuels on global warming and the importance of managing carbon dioxide levels to mitigate climate change.

What is global warming often associated with?

• Increased rainfall

• More frequent earthquakes

• Rising global temperatures

• Decreased sunlight
