Math 595 MP
Special Topics in Math/Physics
Topic for Spring Semester2020:
Mathematical
Climate Modeling
 


The global climate crisis is the greatest threat humanity has ever faced. At the current rate of greenhouse gas emissions, climate models predict a global average temperature rise of 4˚C to 7˚C beyond pre-industrial averages by the year 2100.  Climate scientists warn that a temperature rise within this range would likely lead to the collapse of civilization, and may even pose an existential threat to humanity and other life on this planet.  In 2018, the Intergovernmental Panel on Climate Change (IPCC) released a report to all governments of the world warning that drastic cuts in emissions of greenhouse gases must occur within the next eleven years to avoid irreversible consequences to Earth’s climate system. 

In this context, climate science has emerged as a leading scientific discipline at universities all around the world, and mathematics plays a key role (see for example, Mathematics of Planet Earth, 2013).  This semester, Math 595 MP will be devoted to the mathematical modeling of Earth’s climate with an emphasis on low dimensional models of the atmosphere and oceans. Topics include Energy Balance Models, Oceans and Climate, Introduction to Dynamical Systems, Radiative transfer, Hydrodynamics, Elementary Thermodynamics, and other topics as time permits.

Exam dates and Homework Assignments


Assignment 1: Read Part 1 of Capitalism & Climate Change: The Science and Politics of Global Warming
and be able to explain clearly and concisely the green house effect (without equations).  Understand how the
carbon cycle works, and know which planet, Mercury or Venus, has the higher global average temperature and why.

Assignment 2: Read and understand Chapter 1 of Mathematics & Climate. 

Assignment 3.  Do these problems and turn in your solutions Wed Feb 5 in class.

Assignment 4.  Do these problems and turn in your solutions Wed Feb 12 in class.

Assignment 5.  Read Chapter 2 of Mathematics & Climate.  Read only: Exercises 1, 2, 3 (you essentially did these already
