An Analysis of Radiative Equilibrium, Forcings, and Feedbacks…with some other random stuff

I have recently posted on the 2009 Mathematics Awareness Month, a forum by the American Mathematical Society, the American Statistical Association, the Mathematical Association of America, and the Society for Industrial and Applied Mathematics that is a national-level event to spread awareness of the importance of Math. This year’s theme was Math and Climate.

I have recently submitted a paper to add to their list of Climate Articles entitled “An Analysis of Radiative Equilibrium, Forcings, and Feedbacks.” It’s a 21 page PDF file.

Mathematics and Climate

Every year in April, there is a Mathematics Awareness Month with the goal to increase public understanding and appreciation for mathematics. This year, the theme for the event is Mathematics and Climate.

GISS summary of Aerosol direct, indirect, and BC albedo effects

Aerosols have played a large role in climate change over the 20th century and have partially offset greenhouse gas warming, leading to a net warming that is smaller than a purely GHG-forced 20th century climate change. They affect climate though their direct ability to reflect shortwave radiation, but also through their indirect influence on cloud cover. A recent study (in press) by some folks at GISS using ModelE have published on aerosol effects from 1890-1995 and I’ll summarize some of their work:
