8:03 pm, my watch read. I’m late! I thought. I started running down Commonwealth Ave to get to ultimate frisbee practice. As I started jogging, I felt a few drops of rain fall down my face. I looked up to the sky and couldn’t help but let my mind wander to Earth’s climate change, and to what I’ve been learning in with BU RECS.
I’ve had a great time in class these past two weeks. Drew Christ, our graduate fellow, gave the first two presentations. Last week, he focused on the Earth’s current climate system. He emphasized that the radiation from the sun is not received evenly throughout the Earth, resulting in a large solar radiation imbalance. Several factors contribute to this imbalance, including varying levels of albedo and changes in the Earth’s tilt due to its rotation. This week, Drew concentrated on climate models. He introduced climate proxies, which are indicators of previous climatic conditions. He taught us about collecting data by studying tree rings, caves, and radiometric dating. The lesson concluded with learning about different types of climate models and their uses.
Overall, I’m excited about how much I’ve learned about Earth’s climate in such a short time. I’m looking forward to next week: the first presentation by my peers!
