Human Impact on Climate Change

Brian from the Scientist in Every Florida School program introduces Dr. Andrew Zimmerman, an associate professor at UF Geological Science Department. Dr. Zimmerman discusses his research on carbon, organic matter, and the carbon cycle, emphasizing their importance in understanding climate change. He explains the internal and external factors affecting Earth's climate, including solar energy, Earth's orbit, and greenhouse gases. The discussion highlights the role of human activities, such as deforestation and fossil fuel use, in altering the climate. Dr. Zimmerman also touches on the natural and anthropogenic variations in greenhouse gases and their impact on global warming. The video concludes with a brief mention of potential solutions and future research directions.
