Public Lecture - Some Thoughts on Global Warming by Harvey Lam

Harvey Lam
Princeton University

Date:  7 November 2012
Time:   2:30 - 4:30 pm
Place:  Room M1603, Li Ka Shing Building

Sau-Hai (Harvey) Lam received his B.S.E. degree in aeronautical engineering from Rensselaer Polytechnic Institute in 1954, and did his graduate work at Princeton University as a Daniel and Florence Guggenheim Jet Propulsion Fellow. After his Ph.D. in 1958, he went to Cornell University as an assistant professor, and came back to Princeton in 1960. At Princeton, he rose through the ranks, and served for six years as the chair of the Department of Mechanical and Aerospace Engineering. He retired in 1999, and is now Edwin Wilsey ’04 professor emeritus. After his retirement, he taught graduate fluid mechanics at Stanford University as a visiting professor . He was elected fellow of the American Institute of Aeronautics and Astronautics in 1996, and member of the American National Academy of Engineering in 2006.
 
Lam’s research interests include: unsteady boundary layers, weakly ionized plasmas, thermionic energy conversions, vibrational relaxations (CO lasers), RNG theory of turbulence, methodologies of singular perturbation and computational singular perturbations, Lagrangian dynamics, non-linear control theory, multi-component diffusions, and global warming modelings.

Abstract
Global warming is caused by excessive atmospheric carbon dioxide because it absorbs (outward) infrared radiations of the earth. The following questions will be addressed and discussed:

- The physics of green house effects, specifically that caused by atmospheric carbon dioxide,

- How much does the globe warms for a given amount atmospheric carbon dioxide increase?

- How much carbon dioxide annual emissions are allowed for a given ceiling of atmospheric carbon dioxide?

- The role of the Earth's thermal inertia,

- How long does it take to achieve stabilization using our best efforts?

- Since “All Men Are Created Equal," how much carbon dioxide can each good citizen of the  Earth emit annually?

- How much of what we know about global warming have been validated by real data, and what  are the uncertainties?

- How much does it cost to solve the problem? Some policy issues.
