The exploration of Mars has fascinated humanity for decades. Once a warm, wet planet, Mars now showcases a cold, arid environment. This dramatic transformation offers valuable lessons about atmospheric changes, the greenhouse effect, and the role of water in shaping landscapes and climates. By comparing the climate histories of Mars and Earth, scientists can identify patterns and processes that influence climate change. Both planets have experienced shifts in axial tilt, orbit, and solar output, demonstrating how celestial mechanics can drive climate variations over millions of years. Mars missions have deepened our understanding of the geological processes that impact climate change. The presence of dust storms and the interaction between the Martian soil and atmosphere highlight how surface features can influence climate. These studies prompt us to consider how Earth’s surface and ecosystems might respond to ongoing climate shifts. Because the Martian surface and atmosphere lack the diverse organic compounds produced by living organisms, changes in Mars’ climate are easier to study. Dr. Auld will lead a discussion on how exploring Mars provides valuable insights into climate change on Earth, offering a unique perspective on the evolution and response of planetary climates to various factors.
