RESULTS OF OUR CO2 MONITORING PROJECT CLICK HERE
The role of CO2 in earth processes is very large relative to the modest quantities of it that are present in the atmosphere. In this course we will study all aspects of the physics, chemistry and biology of CO2. The course is structured around the new atmospheric CO2 monitoring facility in the E&ES department.
In addition we will look into the structure of CO2 molecules, techniques to measure CO2 , and carry out experiments with growing plants.
The E&ES CO2 monitoring site will begin collecting data when the course starts. We will compare the Wesleyan CO2 record with those from elsewhere and interpret variations in measured CO2 contents at different time scales (day/night; weekly, seasonal, long-term) in terms of local and regional fluxes of CO2.
We will extract CO2 databases from the WEB and replot them with our data, calculate fluxes of absolute amounts from data series, and other computer exercises.
We will do some class lab exercises with the program SIMEARTH - you can manipulate the intensity of the sun, the extent of the biosphere, atmospheric CO2 and more, and create your own ice ages and global warming scenarios.
Student groups will create scenarios of global warming
for emission densities of CO2 in the world, and write essays
or give presentations on scientific and political aspects.

==> CLIMATE FUNDAMENTALS (HANDOUTS)
Calculate the "blackbody temperature" of Venus, Earth and Mars, assuming
no atmosphere on these planets. The distances from the center of the sun
to the center of the planets are as follows: Venus:108 million km; Earth:
150 million km; Mars:228 million km. All other constants are in the table
in the back of the handout. To do it right, you can express the distance
from the sun to the planets in units of solar radii. Use Boltzman and Wien,
knowing that the maximum wavelength in the solar spectrum is around 0.48
