I am releasing version 1.0 of my Skeptical Layman's Guide to Anthropogenic Global Warming.  You may download the pdf (about 2.7 mb) from the link above or by clicking on the cover photo below.  In the next few days, I will also be posting an online HTML version as well as offering a printed version at cost.

Update:  The HTML version is here, and the book can be purchased at cost through this link

The purpose of this paper is to provide a layman's critique
of the Anthropogenic Global Warming (AGW) theory, and in particular to
challenge the fairly widespread notion that the science and projected
consequences of AGW currently justify massive spending and government
intervention into the world's economies. This paper will show that despite good evidence that global temperatures
are rising and that CO2 can act as a greenhouse gas and help to warm the Earth,
we are a long way from attributing all or much of current warming to man-made
CO2. We are even further away from being
able to accurately project man's impact on future climate, and it is a very
debatable question whether interventions today to reduce CO2 emissions will substantially
improve the world 50 or 100 years from now. 

I am not a trained expert on the climate. I studied physics at Princeton University before switching my
major to mechanical engineering, where I specialized in control theory and
feedback loops, a topic that will be important when we get into the details of
climate change modeling. For over ten
years, my business specialty was market prediction and sales forecasting using
modeling approaches similar to (if far less complex than) those used in climate.

My goal for this paper is not to materially
advance climate science. However, I have
found that the global warming skeptic's case is seldom reported well or in any
depth, and I wanted to have a try at producing a fair reporting of the
skeptic's position.  I have been unhappy
with several of the recent documentaries outlining the skeptic's case, either
because they skipped over a number of critical issues, or because they
over-sold alternate warming hypotheses that are not yet well understood.  To the inevitable charge that as a
non-practitioner, I am not qualified to write this paper --I believe that I am
able to present the current state of the science, with a particular emphasis on
the skeptic's case, at least as well as a good reporter might, and far better
than most reporters actually portray the state of the science. Through this paper I will try to cite sources
as often as possible and provide links for those who are reading this online,
this report is best read as journalism, not as a scientific, meticulously
footnoted paper.
