Carbon Cycle - Greenhouse Gases, Photosynthesis, Respiration, C Burial, and More

Explore the intricate workings of the carbon cycle and other major elemental cycles in this comprehensive 21-minute video. Delve into the biogeochemical processes involving carbon, oxygen, phosphorous, nitrogen, sulfur, hydrogen, and water. Learn about chemical reservoirs, the greenhouse gas effect, and the crucial role of carbon dioxide in Earth's climate. Understand the photosynthesis-respiration cycle, including how plants utilize oxygen at night. Examine carbon burial, decomposition, and the concepts of negative and positive feedback loops. Discover how carbon isotopes are used to track burial rates throughout Earth's history, study early life on our planet and potential life on other celestial bodies, and provide evidence for human-caused climate change. Gain insights into the isotopic composition of atmospheric carbon dioxide derived from fossil fuels and its implications for current climate trends.
