Supplemental
Peterson et al. (2008), The myth of the 1970's global cooling scientific consensus, Bulletin Amer. Meteo. Soc., 34, 1325. Based on number of journal publications and reports by official scientific organizations, the dominant concern during the 1970's was global warming, not global cooling, as sometimes alleged.
Holdren et al. (2008), Science and Technology for Sustainable Well-Being, Science, 319, 424-434. Outstanding overview of human needs from a global perspective by the former President of the American Association for the Advancement of Science and current science advisor to President Obama. Holdren advocates for a more active and effective role of science in addressing those needs. Article discusses climate change, but serves to put climate change into a larger context of critical problems facing the world (and opportunities for addressing them).

IPCC 2007 Working Group I: Technical Summary (73pp). Scientific Assessment. The "Technical Summary" (TS) is longer than the "Summary for Policymakers" (SPM), but worth looking at for the many excellent graphics and more complete discussions and explanations.
Working Group I: Frequently Asked
Questions. Background explanation of several key topics, aimed at the
general reader. Very useful.
IPCC 2007, WG I, Chap 1: Historical Overview of Climate Change Science. Mostly a review of science over the period of IPCC reports (1990-2007). Contains a lot of useful information, although style is pretty dry. Reads more like a textbook than a critical analysis.
The Carbon Dioxide Greenhouse Effect, by Spencer Weart
Excellent
scientific history showing how 19th and early 20th researchers pieced together
an understanding of how trace constituents in the atmosphere are responsible
for keeping the Earth's surface warm and habitable and of how of how an
initially skeptical scientific community came to understand that burning fossil
fuels was in fact causing the global concentration of carbon dioxide to
increase.
Gardner and Stern (2008), The short list: The most effective actions US households can take to curb climate change, Environment, Sept/Oct, 2008. Many lists exist, but rarely are they prioritized. This article quantifies and compares the energy savings from various actions and, more generally, discusses strategies for more effective use of voluntary action by individuals. WARNING: Article is best read on-line. The print version is poorly formatted and lacks the references.

Kerr (2006), Getting warmer, however you measure it, Science, 304, 805. Something of a watershed moment for global warming science. Satellite temperature data seemed to show absence of warming, contradicting the surface thermometer record. This was a key argument of the so-called "global warming skeptics". UW professor Qiang Fu and graduate student Celeste Johanson found a problem in the way the satellite data had been analyzed. When corrected, satellite and surface records agree - Earth is getting warmer.

Hansen et al., 1988, Global climate changes as forecast by the Goddard Institute for Space Studies three dimensional model, J. Geophys. Res., 93, 9341-9364.
This article
contains specific climate-model predictions for how the Earth's temperature
will change over the next 50 years - including rate of increase and
geographical pattern of increase (where it will warm the most and the
least). The first 20 years of
predictions can now be compared to the actual changes that have been measured. This is one of the best ways we can evaluate
confidence in climate models. How well
did Hansen and colleagues do?

Caldeira et al. (2003) Climate sensitivity uncertainty and the need for energy without CO2 emissions, Science, 299, 2052-2054. Present uncertainty in climate sensitivity translates into far higher (truly enormous) uncertainty in how much carbon the world can emit prior to crossing a threshold of "dangerous climate change". Nevertheless, even for low sensitivity, there will need to be radical changes in energy sources during this century. See, too, an excellent related article (Hoffert et al., 2002) on potential sources of carbon-free energy.
Keenlyside et al. (2008), "Advancing decadal-scale climate prediction in the North Atlantic sector" Nature, 453, 84-88. The title is innocuous, but the implications of this article (if it is right) are politically and scientifically explosive. A method for short-term climate predictions (10-20 years) is presented based on cycles of large-scale ocean currents. The model predicts that global mean temperatures will be flat for the next decade. Since they have already been flat since 1998, this would mean 2 decades of flat temperatures, very much in contrast to IPCC predictions that Earth will warm at a rate of about 0.2 C/decade. A nice summary and context by Richard Wood ("Natural ups and downs") is provided in the same issue of Science.

Baliunas (2003) and critical review by Mann
(2003)
Soon and Baliunas
reanalyze climate proxy data and claim that the 20th century was not unusually
warm when viewed in the context of the past 1000 years. This analysis dramatically contracted the
IPCC 2001 report which had, in fact, emphasized exactly the reverse. The report was published in a fairly obscure
journal and was quickly discredited within the scientific community (e.g. the
Mann et al. review above). But it was
seized upon with great enthusiasm by global warming skeptics and the Bush White
House even attempted to re-write an EPA report on global warming featuring the
results of this article instead of the IPCC.
Global
Warming Petition and Fake Article (1998), Report
on same by Robert Park (1998):
In 1998, thousands
of U.W. scientists received a petition on global warming. The mailing included a background paper on
the subject, formatted to look like a peer-reviewed publication. In fact, it was simply a rambling attack on
the global warming theory which was never peer reviewed or published. Those receiving the petition were mostly not
climate scientists and, therefore, would not necessarily recognize the numerous
mistakes and inaccuracies contained in the article. It was a shoddy act of manipulation, but many
scientists fell for it. The petition
results were then used to assert that most U.S. scientists do not believe
global warming is real.
Lomborg, Bjorn. Cool It: The Skeptical Environmentalist's Guide to Global Warming. Knopf, 244 pp. Lomborg is not a climate scientist but an economist/statistician. His basic argument is that money spent trying to reduce GHG emissions would be better spent directly combating human problems like poverty, hunger, disease, and vulnerability to extreme weather. This is certainly worth considering. However, the vast bulk of the book is a series of efforts to minimize the dangers of global warming and these arguments are not, for the most part, based on sound science.

Lockwood, M. and Froehlich, C (2007). "Recent oppositely directed trends in solar climate forcings and the global mean surface air temperature", The Royal Society, 14 pp. A favorite argument of global warming skeptics is that recent climate changes are tightly correlated with solar variations, implying that they are caused by the Sun and not by any human factors. Unfortunately (for this hypothesis), the correlations fall apart when data from the last decade are included.

Pielke, Jr. et al., 2008, Dangerous Assumptions, Nature, 452, 531-532.
This article reveals a little-known but extremely important aspect of the IPCC Business-as-Usual emission scenarios - namely, that the predicted emissions assume there will be steady improvements in energy efficiency. Thus, when governments tout improved efficiency as evidence that they are tackling the climate change problem, it is likely that they are, in fact, just following the predicted BAU trajectory. In other words, to get off the BAU trajectory requires much more change than is commonly assumed.
Prins and Rayner, 2007, Time to ditch Kyoto, Nature, 449, 973-975.
This 3-page commentary provides a hard-hitting critique of international attempts so far to control GHG emissions.

Two responses were published a few weeks later - one agreeing that Kyoto has failed but disagreeing with the diagnosis; the other defending Kyoto and current international policy efforts.

Solomon et al., 2009, Irreversible climate change due to carbon dioxide emissions, Proc. Nat. Acad. Sci., 106, 1704-1709.
It is likely that CO2 concentration in the atmosphere will peak during this century and slowly decline thereafter, as the world transitions away from energy sources that emit CO2. However, "peak CO2" could be anywhere from 450 ppm (for extremely rapid emissions reductions) to 1200 ppm (for continued reliance on fossil fuels until they are mostly gone). This article argues that the "peak CO2" concentration caused by the present generation humans will set the level of climate change for the next 1000 years. During this 1000 year period, temperatures will remain about the same and sea level will continue to rise.

Fargione et al., 2008, Land clearing and the biofuel carbon debt, Science, 319, 1235-1237.
From the Abstract: "Converting rainforest, peatlands, savannas, or grasslands to produce food-crop-based biofuels in Brazil, Southeast Asia, and the United States creates a 'biofuel carbon debt' by releasing 17 to 420 times more CO2 than the annual greenhouse gas reductions that these biofuels would provide by displacing fossil fuels." This is one of a pair of articles published
Laurance, W. F., 2007, Switch to corn promotes Amazon deforestation, Science, 318, 1721.
This brief letter outlines the problem of crop subsidies in the U.S. intended to support "renewable energy" by encouraging production of corn-based ethanol actually have the effect of promoting tropical deforestation in Brazil as well as increasing food prices world wide.
Searchinger et al., 2008, Use of U.S. croplands for biofuels increases greenhouse gases through emissions from land-use change, Science, 319, 1238-1240.
The title pretty much says it all. Switching from gasoline to corn- and soy-based ethanol results in an increase of greenhouse gas emissions, even though corn-based ethanol is a "renewable" fuel. The problem arises because of the global food market. By reducing food supply, you drive up food prices which results in more tropical forest being cleared to grow crops. The carbon released from the tropical forests more than offsets the carbon saved by using corn-based ethanol. This is one of a pair of articles published in Science that shook up thinking with regard to biofuels. The other article is Fargione et al., 2008.

information
Several recent
studies have shown Greenland and Antarctic glaciers breaking up faster than
what was expected even a 5 years ago. Richard Kerr reviews this recent
evidence and ponders whether these might be the early signs of a major change
in understanding about global warming. Bindshadler provides another
review of the evidence. The Overpeck
article is more substantial and detailed.
He approaches this issue by comparing climate predictions for the next
100 years to what we know about a slightly warmer period in the distant past -
the previous interglacial period of 130,000 years ago. All of these
articles should be incorporated into your report, along with the 2008 update
(see below). (You probably don't need the Overpeck "Supplemental

The open nature of the IPCC review process is quite unusual in science. For the most part, peer-reviews and author replies are confidential and known only to journal editors and the involved parties. However, given the importance of the IPCC findings, it has been decided that all comments and author responses (through two rounds of review) will be made publicly available on the web. This information is potentially of enormous value to scholars studying the scientific process and the interface between science and society.

Lovelock, James. The Revenge of Gaia: Earth's Climate Crisis and the Fate of Humanity, Basic Books, 159 pp. Lovelock is a tremendously creative and important earth-system scientist. This book, however, is a bit over-the-top in presenting the gravity of the threat to humanity posed by global warming. And it is downright peculiar in the solutions it advocates: wind-energy is terrible because it destroys the aesthetics of the rural English countryside; nuclear energy is great because ... well, because Lovelock is certain all the dangers can be easily overcome.
Baird et al. (2008) "Coral Adaptation in the Face of Climate Change". Science, 320, 315. Letter and response. The letter is a comment on an article by Hoegh-Guldberg et al. (2007) that estimated worldwide damage to coral reefs from rising temperatures and ocean acidification. Baird et al. argue that coral mortality may have been overestimated because the coral may be more adaptable than Hoegh-Guldberg assume. There is also a response by Hoegh-Guldberg.

Caldeira et al. (2003) Climate sensitivity uncertainty and the need for energy without CO2 emissions, Science, 299, 2052-2054. Present uncertainty in climate sensitivity translates into far higher (truly enormous) uncertainty in how much carbon the world can emit prior to crossing a threshold of "dangerous climate change". Nevertheless, even for low sensitivity, there will need to be radical changes in energy sources during this century. See, too, an excellent related article (Hoffert et al., 2002) on potential sources of carbon-free energy.

From the Abstract: "Converting rainforest, peatlands, savannas, or grasslands to produce food-crop-based biofuels in Brazil, Southeast Asia, and the United States creates a 'biofuel carbon debt' by releasing 17 to 420 times more CO2 than the annual greenhouse gas reductions that these biofuels would provide by displacing fossil fuels." This is one of a pair of articles published

impact of increasing atmospheric carbon dioxide, Science, 213, 957-966.
An outstanding
overview of global warming science and prediction of what is to come. As
it is now more than 20 years later, the predictions can be tested to a great
extent. How well did they do?
Hansen et al., 1988, Global climate changes as forecast by the Goddard Institute for Space Studies three dimensional model, J. Geophys. Res., 93, 9341-9364.
This article
contains specific climate-model predictions for how the Earth's temperature
will change over the next 50 years - including rate of increase and
geographical pattern of increase (where it will warm the most and the
least). The first 20 years of
predictions can now be compared to the actual changes that have been
measured. This is one of the best ways
we can evaluate confidence in climate models.
How well did Hansen and colleagues do?
Hoegh-Guldberg et al. (2007). "Coral Reefs Under Rapid Climate Change and Ocean Acidification", Science, 1737-1742. Updated estimate of worldwide damage to coral reefs from rising temperatures and ocean acidification. (CO2 is the main cause of both effects. It is a greenhouse gas in the atmosphere, and the part that dissolves into the ocean forms carbonic acid.) A comment (by Baird et al.) and response (by Hoegh-Guldberg et al.) were published in 2008.

science in addressing those needs. Article discusses climate change, but
serves to put climate change into a larger context of critical problems facing
the world (and opportunities for addressing them).
Keenlyside et al. (2008), "Advancing
decadal-scale climate prediction in the North Atlantic sector" Nature,
453, 84-88. The title is innocuous, but
the implications of this article (if it is right) are politically and
scientifically explosive. A method for
short-term climate predictions (10-20 years) is presented based on cycles of
large-scale ocean currents. The model
predicts that global mean temperatures will be flat for the next decade. Since they have already been flat since 1998,
this would mean 2 decades of flat temperatures, very much in contrast to IPCC
predictions that Earth will warm at a rate of about 0.2 C/decade. A nice summary and context by Richard Wood ("Natural ups and
downs") is provided in the same issue of Science.
Kerr, R. (2006), "A Worrying Trend of Less Ice, Higher Seas", Science, 311, 1698-1701.
Kerr (2006), Getting warmer, however you measure it, Science, 304, 805. Something of a watershed moment for global warming science. Satellite temperature data seemed to show absence of warming, contradicting the surface thermometer record. This was a key argument of the so-called "global warming skeptics". UW professor Qiang Fu and graduate student Celeste Johanson found a problem in the way the satellite data had been analyzed. When corrected, satellite and surface records agree - Earth is getting warmer.
Kerr, R. (2008). "Greenland Ice Slipping Away but Not All That Quickly", Science, 320, 301. This is a 1-page news report discussing the latest findings on the possibility of rapid disintegration of the Greenland ice sheet. Substantial sea-level rise this century due to Greenland now seems unlikely, although there are remaining mysteries. Much better monitoring would help.

oppositely directed trends in solar climate forcings and the global mean
surface air temperature", The Royal Society, 14 pp. A favorite argument of global warming
skeptics is that recent climate changes are tightly correlated with solar
variations, implying that they are caused by the Sun and not by any human
factors. Unfortunately (for this
hypothesis), the correlations fall apart when data from the last decade are
included.
Lorius et al., 1990, The ice-core record: climate sensitivity and future greenhouse warming, Nature, 347, 139-145.
An excellent
example of using the energy-balance theory of climate change. Lorius and
colleagues diagnose how sensitive the earth's climate is by looking at
temperature changes and greenhouse gas forcings associated with the last
ice-age.

Peterson et al. (2008), The myth of the 1970's global cooling scientific consensus, Bulletin Amer. Meteo. Soc., 34, 1325. Based on number of journal publications and reports by official scientific organizations, the dominant concern during the 1970's was global warming, not global cooling, as sometimes alleged.
Pielke, Jr. et al., 2008, Dangerous Assumptions, Nature, 452, 531-532.
This article reveals a little-known but extremely important aspect of the IPCC Business-as-Usual emission scenarios - namely, that the predicted emissions assume there will be steady improvements in energy efficiency. Thus, when governments tout improved efficiency as evidence that they are tackling the climate change problem, it is likely that they are, in fact, just following the predicted BAU trajectory. In other words, to get off the BAU trajectory requires much more change than is commonly assumed.
Prins and Rayner, 2007, Time to ditch Kyoto, Nature, 449, 973-975.
This 3-page commentary provides a hard-hitting critique of international attempts so far to control GHG emissions. More importantly, it provides specific recommendations for how to change course and do better. Two responses were published a few weeks later - one agreeing that Kyoto has failed but disagreeing with the diagnosis; the other defending Kyoto and current international policy efforts.

Raupach et al. (2007). "Global
and regional drivers of accelerating CO2 emissions", PNAS,
10288-10293. Despite the Kyoto treaty,
global emissions of CO2 have accelerated in the last 5 years such that emission
rates now exceed the worst-case scenarios laid out a decade ago by IPCC. This article documents the steep increase and
the economic/technological forces that are driving it.
Searchinger et al., 2008, Use of U.S. croplands for biofuels increases greenhouse gases through emissions from land-use change, Science, 319, 1238-1240.
The title pretty much says it all. Switching from gasoline to corn- and soy-based ethanol results in an increase of greenhouse gas emissions, even though corn-based ethanol is a "renewable" fuel. The problem arises because of the global food market. By reducing food supply, you drive up food prices which results in more tropical forest being cleared to grow crops. The carbon released from the tropical forests more than offsets the carbon saved by using corn-based ethanol. This is one of a pair of articles published in Science that shook up thinking with regard to biofuels. The other article is Fargione et al., 2008.

Solomon et al., 2009, Irreversible climate change due to carbon dioxide emissions, Proc. Nat. Acad. Sci., 106, 1704-1709.
It is likely that CO2 concentration in the atmosphere will peak during this century and slowly decline thereafter, as the world transitions away from energy sources that emit CO2. However, "peak CO2" could be anywhere from 450 ppm (for extremely rapid emissions reductions) to 1200 ppm (for continued reliance on fossil fuels until they are mostly gone). This article argues that the "peak CO2" concentration caused by the present generation humans will set the level of climate change for the next 1000 years. During this 1000 year period, temperatures will remain about the same and sea level will continue to rise.
Strand, S. E. and Benford, G. (2009), "Ocean sequestration of crop residue carbon: Recycling fossil fuel carbon back to deep sediments", Environ. Sci. Technol., in press. Lead author is UW professor in College of Forest Resources. Authors claim that dumping bales of crop residue into the ocean is far more efficient that other proposed methods of carbon sequestration and could be implemented now with existing technology and infrastructure. It could remove about 0.6 GtC/yr, or about 15% of current rate of global increase in atmospheric CO2.
