Earth and Environmental Sciences

Dinosaurs  explores how science works and provide practical knowledge about the history of life and how we have come to understand it. We learn how to analyze the evolutionary relationships of organisms and examine how dinosaurs came to be exemplars of a very successful group of organisms dominant on land for 140 million years. We will delve deeply into how direct descendants of small carnivorous theropod dinosaurs evolved into birds, still more diverse than mammals, dominating the air. The Mesozoic, a “hot-house world”, with no ice caps and was the kind of world we are hurtling towards because of our input of greenhouse gases into the atmosphere, and we will look at how their time is a natural experiment for our future. The non-avian dinosaur met their end in a remarkable cataclysm discovered by detective work that we will delve deeply into as a paradigm of the scientific method  Finally, they are fun and spectacular - monsters more fantastic than any person has invented in legend or religion - and they are still with us!  

In responding to the environmental issues we face today, it is critical to recognize the science behind them. This course will teach students the basic concepts in earth science/geology essential to understanding the mechanisms of our current climate crisis. These foundational concepts are crucial for any student who is interested in not only the natural sciences, but for those who wish to pursue careers related to environmental justice, sustainability, and other social science fields. Students will explore how and where natural resources form, as well as how we are rapidly depleting these reserves. Students will also learn about natural disasters and how these affect certain communities more than others. Students will gain an understanding of the formation of rocks and minerals and their economic significance. Students will be able to use the cumulative knowledge they gained during the first weeks of class to have a better understanding of the global climate issues we face and to use this information to conduct presentations on an environmental topic of their choice. The format of the course will be as follows:  Primarily lecture, followed by class discussions, group activities and at least one lab component.

The course examines the modern atmosphere, ocean, cryosphere and other components of the Earth’s climate system, and considers how they have changed in the past. Topics include global energy balance, greenhouse gases, thermodynamics of the atmosphere, moisture and clouds, ocean biology, chemistry and physics. The general circulation of the atmosphere as well as the surface and deep ocean will be considered from first principles and modern observations. Multiple intervals of Earth’s past will be considered, including substantially warmer and colder periods than the modern, as well as the repeated oscillations between glaciations and interglacial episodes of the past two million years. Some emphasis will be place on relatively rapid climate changes that have occurred naturally in the past, and the course will conclude with a consideration of recent trends and future projections.
