GEOL-342CC Seminar in Geology: 'Global Effects of Climate Change'

Spring. Credits: 4

Climate change is shifting the historical climate due to temperature increases and changing weather patterns. Historical monitoring of atmospheric gases has shown that anthropogenic contributions since the Industrial Revolution are the leading causes. Today, the effects of climate change vary by location and are most visible in weather patterns, where some locations are becoming wetter or dryer. The global temperatures of land surfaces and oceans have increased over time, and these shifts have also directly affected biodiversity and human activity. This discussion-based seminar aims to cover peer-reviewed articles on the effects of climate change in different regions of the world.
