Where to Read about Climate Change ?

      Version 6,  July 1995.    For changes see the contents.

Commented books and articles.  Many entries aim at general readers
with some basic science background.  Where possible, journals that are
difficult to access are avoided.  My spare time has been curtailed,
this may well be the last version.  Grab it  ;-)

Most entries address the science of climate change, although some
material on impacts and responses has been included.  Before turning
to climate change, some might prefer a look at the climate, which
is provided by sections 2.4 to 2.6.  Sections 2.7 to 2.9 go beyond
climate and try to hint a broader view.

For starters:  If you are out for short introductory overviews,
then try section 3.1.  For somewhat broader nontechnical primers
see section 2.1.  The IPCC Reports in section 1 are more thorough;
they are not always easy to read, though accessible to patient
general readers with some basic scientific knowledge.

* 1.1  What is the IPCC ?

The Intergovernmental Panel on Climate Change (IPCC) was set up in 1988
by the World Meteorological Organization (WMO) and by the United Nations
Environment Programme (UNEP).  The IPCC tries to provide the best
possible description of the climate change situation as an input to the
political decision making process.  IPCC Reports address both professio-
nals and interested general readers.  They contain lots of references
and are frequently quoted in the peer-reviewed scientific literature.
They are not easy to read, but the gist is accessible to patient general
readers with some basic scientific knowledge.  Reports and individual
sections are preceded by summaries that are easier to read and provide
acceptable shortcuts.

The IPCC formed three working groups, each of which involves hundreds
of researchers and other specialists from many countries:
  I    Science.   Working Group I is the `climate' group.  Most of
       its participants are climatologists and meteorologists,
       including many of the world's most respected researchers.
  II   Impacts.   Working Group II tries to assess potential
       environmental and socio-economic impacts of climate change.
  III  Response Strategies Working Group (RSWG).  Working Group III
       attempts to lay out a set of response policy options and the
       factual basis for those options.
In late 1992, the tasks of the Working Groups were partly reshuffled:
  I    Science   (more or less unchanged)
  II   Impacts.  Responses:  Emissions control, adaptation
  III  Economics
The bulk of the Second IPCC Assessment is scheduled for late 1995.  Its
first installment was the report on radiative forcing, see section 1.2.
It seems that new scientific findings will not substantially alter the
main results of the 1990/1992 Scientific Assessment.  The Second Assess-
ment on Impacts and Responses by Working Group II is to contain almost
30 chapters and likely to be more detailed than the 1990 Assessment.

Treats carbon dioxide and the global carbon cycle, other trace gases
and atmospheric chemistry, natural and human-made aerosols, radiative
effects of trace gases and aerosols, global warming potentials, and
trace gas emission scenarios.  Knowledge about human-made aerosols
is still fledgling, quantifying their cooling effects more precisely
looks like a Sisyphean task.  Includes summaries and a short index.

Authoritative statement of the contemporary views of the broad majority
of climatologists worldwide.  Often called a `consensus'.  This is true
provided one keeps in mind there is consensus that there are many uncer-
tainties in the predictions.  Uncertainty cuts two ways.  Present best
estimates may well overstate the risk.  They may as well understate it.
The climate change issue resembles a gamble with high stakes.  Narrowing
the uncertainties is likely to take considerable time.  No index :-s

Summarizes knowledge up to mid-1990.  Reliable predictions for regional
climate change are presently not available, thus much of the impacts
research is of the  what if? - variety.  Topics include agriculture,

A good place to start.  John Houghton co-chairs Working Group I, the
`climate' or `science' group of the Intergovernmental Panel on Climate
Change (IPCC).  Readably written for a general audience, the book offers
a well-organized summary of the IPCC's findings, amended by some helpful
basics.  Diligently exposing the uncertainties, Houghton addresses the
science of climate change and, in less detail, potential impacts and re-
sponses.  At times, Houghton strikes a more personal tone, making clear,
though, where science ends and personal judgment takes over.  Amusingly,
the dust-jacket capitalizes on one of the book's rare obvious errors:
garden glasshouses do not work like the atmospheric greenhouse effect.

Allround: science, impacts, responses.  Coverage of topics is a bit
eclectic, though.  Mostly readable, prone to occasional typos.  About
40 authors and 60 reviewers from a large number of countries.  From
chapter 1:  "If you come away from this volume with one understanding,
it should be of the importance of linkages: the interconnections
between risks of rapid climate change and so many other problems
of central concern ... "

A moderate skeptic's view, easy to read, and, barring the polemic
and sloppy introduction by A. Wildavsky, responsibly written.  For
my taste, past climates, the ice record of greenhouse gases, and the
possibility of unpleasant surprises receive too little attention.
The discussion of the modern global temperature record is not entirely
even-handed.  Yet, altogether this is a useful account of many aspects
of the topic.  Balling hopes for rapid progress in understanding and
presumes that the most probable course of events may be relatively
benign.  He cautions, though:  "Only time will tell".

Papers grown out of a workshop held in 1989, including quite a few of
the most respected workers in the field. Somewhat to highly technical,
for readers with a scientific bent only.  As the title suggests, this

        Cambridge University Press, 1993.  788 pages, 35 pounds, $49.95
The first book is a starter, covering the various types of climate
models.  The second text presents, in varying depth, climate related
-  that is: most  -  aspects of the earth system and how to model them.
"Is climate system modelling the ultimate example of hubris, or, by
chopping away at areas of ignorance, will we truly improve our predic-
tive capability ?   A thorough reading of   _Climate System Modeling_
provides support for both points of view."    (David Rind, Nature 363,

     Oxford University Press 1991.   viii, 339 pages
     ISBN 0-19-503963-7   (approx. $60)
Somewhat to highly technical, but many narrative passages and figures
are accessible to interested general readers.  Much space is devoted
to an overview of past climates with emphasis on the past 20,000 years.
For information about climate changes, the past is a unique place to
go.  Yet, there are "no completely satisfactory geologic analogs" for
the expected future climate state (p 254).  On the other hand (p 252),
"the intrepid reader of our book will [realize] that we cannot explain
much of the climate variance over earth history unless the greenhouse
effect is about as large as the models project."

     paper, $ 18.95, 16.95 pounds
"... a readable and up-to-date summary of many of the aspects of global
ecology required for an understanding of the present state of play.
The coverage of topics is necessarily diverse, and brief, ranging from
the astronomical theory of orbital forcing as a mechanism for Quaternary
climate change, to plant physiology, drought and El Nino events.
Emphasis is placed on vegetation responses to global change;  past
vegetational response, the use of forest models and ecosystem responses
comprise most of the book.  ...  will be of use to students new to the
subject but adds little to the knowledge of those already working in the
field."                David J. Beerling,  Nature 364 (1993), 24

This text might serve to supplement the books by Graedel & Crutzen (see

This is an introduction written for College Sophomores and Juniors; it
requires no background beyond Freshman Physics and Chemistry. It heavily
emphasizes chemistry, but does touch on geology, dynamics and radiative
processes.  A particularly valuable part of the book discusses the
methods used for determining the budgets of various trace species in the
environment.  Most of the issues in current research are discussed, but
none of them in much depth  -  this is a place to start, not a place to
find a comprehensive treatment.  My copy has a number of misprints, in-
cluding some in the figures; watch out for them.       (Contributed by

The goal of this interesting book, only part of which deals with
climatology, is to learn  "how to use relatively simple mathematical
methods (often of the 'back-of-the-envelope' variety) to understand
how planet earth and its inhabitants interact."  The math is generally
simple, yet the problem-solving approach is quite informative.  It
covers global mean temperature, the greenhouse effect, CO2 effects,
land use changes, the urban heat island effect, and feedbacks.  The
appendix provides some useful numbers.  Includes many worked out
examples and a moderate bibliography.  (Contributed by Dave Halliwell)

temperature record is currently not feasible.  The climate change issue
resembles a gamble.               (Pointed out by Roger Wilson)

White, then president of the National Academy of Engineering,
formerly president of the American Meteorological Society, summarizes
the history of the field, some of the basic facts and the US debate
up to 1990.  Argues for a `no regrets' policy or, in gambling terms,
for `spreading your bets'.   "What would be unwise is to lapse into
apocalyptic thinking or ostrichlike denial."

* 3.2  If You Need to Dig More Deeply

     M.D. Handel,  J.S. Risbey,   An annotated bibliography
     on the greenhouse effect and climate change
     Climatic Change 21 (1992), 97-255
Over 600 important publications up to early 1992 are reviewed.  The
selection of entries tries to facilitate introduction to important
issues and findings.  The subjects are:  Theory and numerical modelling,
carbon dioxide and other trace gases, climate change observations,
paleoclimatology, impacts and interactions, policy, history, other
causes of climate change, non-technical introduction, miscellaneous.
This bibliography is an invaluable asset if you want or need to dig
more deeply into the matter.  It can spare you lots of searching time.

* 3.3  Impacts and Responses

     Jesse H. Ausubel,  A second look at the impacts of climate change
     American Scientist 79 (1991), 210-221
Easy to read, adapted from an NAS study.  Ausubel is critical about
some conventional wisdoms, but not complacent.  He argues that poor
countries are more vulnerable than rich countries, and he is concerned
about fresh water resources and ecosystems.  Ausubel is certainly right
that narrowing down the uncertainties is crucial.  Unfortunately,
this might take longer than we would like.

     William D. Nordhaus,  Expert opinion on climatic change
     American Scientist 82 (1994), 45-51
19 people with expertise in the area  (economists, social scientists,
natural scientists, engineers)  were asked to estimate the economic
impact of climate change.  Opinions diverged wildly.  As one respondent
quipped, this  "was hardly surprising, given that the economists know
little about the intricate web of natural ecosystems, whereas scientists
know equally little about the incredible adaptability of human econo-
mies."   Food for thought, reminding of Epiktet's opinion that humans
are not startled by things but by their perception of things.

     V. Ramanathan,    The greenhouse theory of climate change:
     a test by an inadvertent global experiment
     Science 240 (1988), 293-299
Useful, mildly technical overview, including the thorny issue of
feedbacks.  This is the most recent easily accessible paper of this
sort I happen to know.  Any proposals for an easily accessible
successor ?     Mark Handel and James Risbey, in their annotated
bibliography on climate change  (Climatic Change 21, 1992, 97-255)
put the following two papers at the top of their list on  "Overviews
of Greenhouse Theory" :

        Rev. Geophys. 27 (1989), 115-139

        radiatively important gases ... read it after ... Mitchell" ]

     History of the greenhouse effect
     Progress in Physical Geography  14, 1 (1990), 1-18
Many interesting tidbits.  In 1827, Fourier compared the influence of
the atmosphere to the heating of a closed space beneath a pane of glass.
In 1909, R.W. Wood found that the glasshouse in your garden retains
heat mainly by lack of convection and advection.  Thus the atmospheric
`greenhouse' effect, which is due to absorption and re-emission of
infrared radiation, is a misnomer.  We won't get rid of it, though ;-)

* 4.2  Global Carbon Cycle

     U. Siegenthaler  &  J.L. Sarmiento
     Atmospheric carbon dioxide and the ocean
     Nature 365 (1993), 119-125
Section 1 of  "Climate Change 1994"  (see above, section 1.2)  discusses
the carbon cycle at some length.  If you prefer something shorter, here
is a nice substitute.  Abstract:  "The ocean is a significant sink for
anthropogenic carbon dioxide, taking up about a third of the emissions
arising from fossil-fuel use and tropical deforestation.  Increases in
the atmospheric carbon dioxide concentration account for most of the
remaining emissions, but there still appears to be a `missing sink'
which may be located in the terrestrial biosphere."

        Discussion: Douglas Sheil, O.P.,  Science 268 (1995), 894-895

In a CO2-rich world, many (especially so-called C3) crops are likely to
grow better and to require less water, provided other growing conditions
like nutrients, temperature and light are favourable.  The long-term
effects of rising CO2 levels on ecosystems are less clear.  Even without
climatic changes, though, the composition of ecosystems will change,
and not necessarily in a way our descendants will celebrate.  Culotta
provides an easy introduction and summary.  Bazzaz and Fajer 1992 (easy)
and Bazzaz 1990 (scholarly) fill in details.  Phillips and Gentry
tentatively suggest that, in tropical forests, a reshuffling of tree
species may already be under way.

        to-century-scale climate variability: climate model results.

     Richard A. Kerr,   Unmasking a shifty climate system.
        Science 255 (1992), 1508-1510

Little is known about natural climatic fluctuations on a decadal to
century scale.  It is unknown what course earth's temperature would have
taken without anthropogenic emissions. Some players that may be involved
in natural climatic variations on this time scale:  Random atmospheric
variations including shifts of the polar front, variations in the circu-
lation of the North Atlantic and of the Pacific Ocean, solar variability,
volcanism.  Unraveling climate's natural vagaries may take a long time:
there is a dearth of sufficiently long and detailed climatic records.

Karl concisely sums up these and other obstacles which currently impede
detecting the effect of human-made greenhouse gases.  Rind and Overpeck
consider potential players in the natural variability game and how they
might be sorted out in the climate record.  They estimate that these
factors, taken together, are unlikely to cause global mean surface
temperature changes exceeding 1 o C.  Kerr recounts a sobering example:
1976/77 something "sudden" happened in the Pacific, including a rise of
tropical Pacific mean surface temperature.  It was, and to my knowledge
still is, unknown whether this was just natural climatic variability
or incipient climate change.  See also Broecker's article (3.1) and
Burroughs' book (2.4).

* 4.5  Night Heat

     Thomas R.Karl,  Philip D.Jones,  and eight more authors
     A new perspective on recent global warming:  asymmetric trends
     of daily maximum and minimum temperature
     Bulletin Amer. Meteorol. Society 74 (1993), 1007-1023
Over many Northern and some Southern Hemisphere land areas a decrease
of the diurnal temperature range has been observed:  nighttime minimum
temperatures went up, while daytime maximum temperatures increased more
slowly and in some regions even decreased slightly.  These changes are
partially related to increases in cloud cover.  The causes are not yet
known, it is open whether the `night heat' is temporary or going to
last.  Possible culprits include the observed global warming and
increases of greenhouse gases, increases in sulfate aerosols, biomass
burning (smoke), natural climate variability and a combination of some
or all of these.

* 4.6  Greenhouse Gases and Climates of the Past

     Thomas J. Crowley,  Geological assessment of the greenhouse effect
     Bulletin Amer. Meteorological Society 74, 12 (Dec 1993), 2363-2373
A concise compendium of the basic knowlegde.  Over the past half billion
years, high levels of carbon dioxide tend to be associated with warm
climate.  Paleoclimate data and climate models so far yield about the
same range for climate sensitivity to greenhouse gas changes.  For warm
periods, climate models indicate warmer tropical surface temperatures
(SST) and cooler high latitude winters than the paleodata.  The models
may well be in error, but at least for tropical SST the data are not
impeccable, moreover the models usually employ present-day geography
and mountain ranges.  As an addendum, skeptics might enjoy a thought-
provoking, though not conclusive, new piece of evidence:

        of hunger.   The Lancet 342 (1993), 1345-1347
        [a summary of the Nature article, easier to read]
So far, one of the most extensive studies of the topic.  Asks how
agriculture may be affected if the warming for a CO2 doubling should be
near the upper end of the estimated range.  Fertilizing effect of CO2
on crops, technological improvements leading to increased yields over
time, and liberalization of food trade are taken into account.  The
results suggest  "only a small decrease in global crop production.
But developing countries are likely to bear the brunt of the problem."
There remain many uncertainties, the results are possible scenarios
but not predictions.

     John Bongaarts,  Can the growing human population feed itself ?
     Scientific American 270, 3 (March 1994), 18-24
Addresses food supply and increasing population in general, with climate
change as a subtopic only.  Bongaarts argues that neither the pessimists
("we cannot feed them")  nor the optimists ("no problem")  are right.
>From the conclusion:  "Feeding a growing world population a diet that
improves over time in quality and quantity is technologically feasible.
But the economic and environmental costs incurred through bolstering
food production may well prove too great for many poor countries.  ...
Whatever the outcome, the task ahead will be made more difficult if
population growth rates cannot be reduced."

* 4.8  Risk Perception and Risk Communication

     M. Granger Morgan,   Risk analysis and management
     Scientific American 269, 1 (July 1993), 24-30
Morgan stresses the roles of risk perception and risk communication.
He is optimistic about his profession's ability to analyze and commu-
nicate risks, but wisely qualifies that the  "public agenda is already
crowded with unresolved issues"  and that complex risks like climate
change are neither well understood nor easy to explain.  Given that
risks are often communicated in fragmentary bits by people who fail to
do their homework or who promote a particular agenda, the  "surprise
is not that opinion on hazards ... may sometimes force silly or
inefficient outcomes.  It is that the public does as well as it does."
