Passionate about solving environmental challenges? Having a hard time understanding the theories and data? Let's approach them in the form of stories! Earth operates as a system with the interactions between atmosphere, hydrosphere, lithosphere, and biosphere. The changes in one part will result in the positive or negative feedback in the entire system. As we entered Anthropocene in the mid-20th century, the anthroposphere will be included in the discussion. In this podcast, we will piece the puzzles together to form a big picture of Earth system using the clues of observations, data, and evidence. We will also address some of the challenges you may face such as forming testable hypothesis, dealing with uncertainty, and applying theories and equations. Our first theme is systematic approach towards climate change.
