Impact of Carbon Dioxide on Climate

Alec discusses the carbon cycle, focusing on its movement through the atmosphere, biosphere, and lithosphere. The biosphere's role in carbon storage is highlighted, with emphasis on photosynthesis and respiration. Human activities like burning fossil fuels and deforestation increase atmospheric carbon dioxide, contributing to climate change. This results in environmental impacts such as temperature rise, altered ecosystems, and species displacement.
