The Hockey Stick and the Climate Wars: Dispatches from the Front Lines, Michael E. Mann (Columbia University Press).
Publisher’s description:
In its 2001 report on global climate, the Intergovernmental Panel on Climate Change of the United Nations prominently featured the “Hockey Stick,” a chart showing global temperature data over the past one thousand years. The Hockey Stick demonstrated that temperature had risen with the increase in industrialization and use of fossil fuels. The inescapable conclusion was that worldwide human activity since the industrial age had raised CO2 levels, trapping greenhouse gases in the atmosphere and warming the planet.
The Hockey Stick became a central icon in the “climate wars,” and well-funded science deniers immediately attacked the chart and the scientists responsible for it. Yet the controversy has had little to do with the depicted temperature rise and much more with the perceived threat the graph posed to those who oppose governmental regulation and other restraints to protect our environment and planet. Michael E. Mann, lead author of the original paper in which the Hockey Stick first appeared, shares the real story of the science and politics behind this controversy. He introduces key figures in the oil and energy industries, and the media front groups who do their bidding in sometimes slick, bare-knuckled ways to cast doubt on the science. Mann concludes with an account of the “Climategate” scandal, the 2009 hacking of climate scientists’ emails. Throughout, Mann reveals the role of science deniers, abetted by an uninformed media, in once again diverting attention away from one of the central scientific and policy issues of our time.

Publisher’s description:
An unprecedented union of scientific analysis and stunning photography illustrating the effects of climate change on the global ecosystem.
In this groundbreaking book, published by W.W. Norton & Company in April 2009 NASA climate scientist Gavin Schmidt and photographer Joshua Wolfe illustrate as never before the ramifications of shifting weather patterns for human society. Photographic spreads show us retreating glaciers, sinking villages in Alaska’s tundra, drying lakes. The text follows adventurous scientists through the ice caps at the poles to the coral reefs of the tropical seas. Marshalling data spanning centuries and continents, the book affirms the headlines with cutting-edge research and visual records, including contributions from experts on atmospheric science, oceanography, paleoclimatology, technology, politics, and the polar regions.
The Long Thaw: How Humans are Changing the Next 100,000 Years of Earth’s Climate, David Archer (Princeton University Press, 2009).
Publisher’s description:
Global warming is usually represented as a hundred-year problem, say to the year 2100. In The Long Thaw, David Archer, one of the world’s leading climatologists, shows how a few centuries of fossil-fuel use will change the climate of the Earth dramatically for hundreds of thousands of years into the future. The great ice sheets in Antarctica and Greenland will take more than a century to melt, we think, but the climate impact from fossil fuel CO2 will last long enough for the ice sheets to respond fully to the warmer climate, changing sea level one hundred times more than the forecast for the year 2100. A planet-wide thaw driven by humans has already begun, but Archer argues that it is still not too late to avert dangerous climate change—if humans can find a way to cooperate as never before.
Reviews:
In this short book, David Archer gives us the latest on climate change research, and skillfully tells the climate story that he helped to discover: generations beyond our grandchildren’s grandchildren will inherit atmospheric changes and an altered climate as a result of our current decisions about fossil-fuel burning. Not only are massive climate changes coming if we humans continue on our current path, but many of these changes will last for millennia. To make predictions about the future, we rely on research into the deep past, and Archer is at the forefront of this field: paleoclimatology. This is the book for anyone who wishes to really understand what cutting-edge science tells us about the effects we are having, and will have, on our future climate.
Richard B. Alley, Penn State University
This is the best book about carbon dioxide and climate change that I have read. David Archer knows what he is talking about
James Hansen, NASA
Books on climate change tend to focus on what is expected to happen this century, which will certainly be large, but they often neglect the even larger changes expected to take place over many centuries. The Long Thaw looks at climate effects beyond the twenty-first century, and its focus on the long-term carbon cycle, rather than just climate change, is unique.
Jeffrey T. Kiehl, NCAR
A great book. What sets it apart is that it expands the discussion of the impacts of global warming beyond the next century and convincingly describes the effects that are projected for the next few thousand years. What also sets it apart is how deeply it takes general readers into the scientific issues of global warming by using straightforward explanations of often complex ideas.
Peter J. Fawcett, University of New MexicoArcher has perfectly pitched answers to the most basic questions about global warming while providing a sound basis for understanding the complex issues frequently misrepresented by global warming skeptics. With a breezy, conversational style, he . . . provides a complete picture of climate change.
—Publishers Weekly[An] enjoyable and fast-paced treatise. . . . Archer leads the reader to a simple yet accurate picture of climate changes, ranging from geological time scales to current warming, ice ages and prospects for the future.
—Susan Solomon, Nature
Dire Predictions: Understanding Global Warming Michael Mann and Lee Kump, (2008).
Publisher’s description:
The Intergovernmental Panel on Climate Change (IPCC) has been issuing the essential facts and figures on climate change for nearly two decades. But the hundreds of pages of scientific evidence quoted for accuracy by the media and scientists alike, remain inscrutable to the general public who may still question the validity of climate change.
Esteemed climate scientists Michael E. Mann and Lee R. Kump, have partnered with DK Publishing to present Dire Predictions–an important book in this time of global need. Dire Predictions presents the information documented by the IPCC in an illustrated, visually-stunning, and undeniably powerful way to the lay reader. The scientific findings that provide validity to the implications of climate change are presented in clear-cut graphic elements, striking images, and understandable analogies.
Readers will be able to understand the IPCC reports’ key concepts such as scientific uncertainty. They will also learn how to build a climate model and use it to predict future climates. Geoforensics is presented as a way to learn from the past by piecing together clues from prior climates.
Independent reviews:
Here’s a powerful, straight-forward guide to how scientists, economists, and engineers really understand the problem of global warming. It makes 20 years of research and consensus-building completely accessible to anyone who cares to know the truth–and to do something about it.
Bill McKibben, author of “The End of Nature”
With its eye-grabbing graphics and reader-friendly prose, “Dire Predictions” walks us through the findings of the world’s leading climate scientists – and places the ultimately responsibility for the human future directly at our feet.
Ross Gelbspan, author of “The Heat Is On” and “Boiling Point”
Dire Predictions is a must read for anyone who wants the straight facts on global warming. It cuts to the heart of the massive 2007 IPCC report, presenting major scientific findings in easy to understand language and graphics. Written by two of the scientific community’s most thoughtful researchers, Dire Predictions’ unbiased message about global warming arrives at a time when people need it most!

Wie bedroht sind die Ozeane?, Stefan Rahmstorf and K. Richardson, (Fischer 2007, in German, English version published 2008)
Publisher’s description:
Die Meere sind eine Grundlage unseres Lebens — sie regulieren unser Klima und sind ein wichtiger Nahrungslieferant. Doch wir zerstören sie durch globale Erwärmung, Überfischung und Verschmutzung. Das wird verheerende Folgen haben, wenn wir nicht rasch umdenken und handeln. Dieser Band zeigt Ansätze auf, wie wir unsere ozeanischen Ökosysteme wirkungsvoll schützen können.
Global warming: Understanding the Forecast, David Archer (Wiley-Blackwell, 2006).
Publisher’s description:
Global Warming: Understanding the Forecast is a comprehensive introduction to all aspects of global warming. Written in an accessible way, this important book examines the processes of climate change and climate stability, from the distant past to the distant future. Examining the greenhouse effect, the carbon cycle, and what the future may hold for global climate, this text draws from a wide range of disciplines, and not only summarizes scientific evidence, but also economic and policy issues, related to global warming. A companion website provides access to interactive computer models of the physics and chemistry behind the global warming forecast, which can be used to support suggested student projects included at the end of each chapter. Global Warming: Understanding the Forecast provides an essential introduction to this vital issue for both students and general readers, with or without a science background.
Independent reviews:
Rigorous but rewarding, David Archer’s book takes us through the science of global warming so that we can more effectively assess where the world may be heading.
Andrew S. Goudie, University of Oxford
David Archer’s book is an accessible, entertaining, but detailed account of how scientists are trying to predict future climate change. It is an excellent book and should be the first port of call for anyone wanting to delve deeper into exactly what goes into those global warming forecasts.
Mark Maslin, University College London, author of Global Warming: A Very Short Introduction
This is a wonderful book. Between the covers of a surprisingly slim paperback, David Archer has distilled nearly everything a concerned undergraduate student could wish to know about the workings of the climate system…overall, this book perfectly hits its target audience.

Solar Activity and Earth’s Climate, Rasmus Benestad, (Praxis-Springer, 2006, 2nd Edition, originally published 2002)
Publisher’s description:
The main purpose of this book is to introduce the reader to the subject of solar activity and the connection with Earth’s climate. It commences with a brief review of the historical progress on the understanding of the solar-terrestrial connection and moves on to an objective scrutiny of the various hypothesis. The text focuses on how knowledge about the solar cycle and Earth’s climate is obtained. It includes discussion of observations, methods and the physics involved, with the necessary statistics and analysis also provided, including an examination of empirical relations between sunspots and the Earth’s climate. The author reviews plausible physical mechanisms involved in any links between the solar cycle and the Earth’s climate, emphasizing the use of established scientific methods for testing hypothesized relationships.

The Forecast in the Streets
The physical impacts of the global warming forecast can be bracketed with some degree of statistical confidence. Biological effects are more difficult to gauge, except in special cases such as the likely demise of polar bears that would result from the demise of Arctic sea ice. The societal effects, however, are nearly uncharted territory, at least to me. Perhaps the topic of global warming suffers from the same sort of cultural divide as university faculties, between the techies and the touchies; that is the sciences and the humanities. A new report (pdf) called The Age of Consequences, just released by the Center for Strategic and International Studies and the Center for a New American Security, tries to bring the social sciences, in particular history, geography, and political science, into the forecast of climate change in the coming century. It makes for fascinating if frightening reading. [Read more…] about The Forecast in the Streets
A barrier to understanding?
People don’t seem to embrace global measures of temperature rise (~0.2ºC/decade) or sea level rise (> 3mm/yr) very strongly. They much prefer more iconic signs – The National Park formerly-known-as-Glacier, No-snows of Kilimanjaro, Frost Fairs on the Thames etc. As has been discussed here on many occasions, any single example often has any number of complicating factors, but seen as part of a pattern (Kilimanjaro as an example of the other receding tropical glaciers), they can be useful for making a general point. However, the use of an icon as an example of change runs into difficulty if it is then interpreted to be proof of that change.
With respect to sea level, the Thames Barrier is a concrete example that has been frequently raised.

Les Chevaliers de l’Ordre de la Terre Plate, Part II: Courtillot’s Geomagnetic Excursion
This article continues the critique of writings on climate change by Allègre and Courtillot, started in Part I . If you would like to read either post in French, please click on the flag icon beside the post title above.
Prelude: It’s the physics, stupid
…which of course is a paraphrase of Bill Clinton’s famous quote regarding the economy. We put the last word in small letters since we’ve learned that it is not a good debating technique to imply (even inadvertently) that those who are having trouble seeing the force of our arguments might be stupid. What we wish to emphasize by this paraphrase is the simple fact that the expectation of a causal link between increasing long-lived greenhouse gases (like CO2) and increasing temperature does not rest on some vague, unexplained correlation between 20th century temperature and 20th century greenhouse gas concentration.
The anticipated increase in temperature was predicted long before it was detectable in the atmosphere, indeed long before it was known that atmospheric CO2 really was increasing; it was first predicted by Arrhenius in 1896 using extremely simple radiation balance ideas, and was reproduced using modern radiation physics by Manabe and co-workers in the 1960’s. Neither of these predictions rests on general circulation models, which came in during subsequent decades and made more detailed forecasts possible.
Still, the basic prediction of warming is founded on very fundamental physical principles relating to infrared absorption by greenhouse gases, theory of blackbody radiation, and atmospheric moist thermodynamics. All these individual elements have been verified to high accuracy in laboratory experiments and field observations. For a time, there was some remaining uncertainty about whether water vapor feedback would amplify warming in the way hypothesized in the early energy balance models, but a decade or two of additional observational and theoretical work has shown that there is no real reason to doubt the way in which general circulation models calculate the feedback. When modified by inclusion of the cooling effect of anthropogenic aerosols, the theory gives a satisfactory account of the pattern of 20th and 21st century temperature change.
No other theory based on quantified physical principles has been able to do the same. If somebody comes along and has the bright idea that, say, global warming is caused by phlogiston raining down from the Moon, that does not make everything we know about thermodynamics, infrared absorption, energy balance, and temperature suddenly go away. Rather, it is the job of the phlogiston advocate to quantify the effects of phlogiston on energy balance, and incorporate them in a consistent way beside the existing climate forcings. Virtually all of the attempts to poke holes in the anthropogenic greenhouse theory lose sight of this simple and unassailable principle.
In a paper entitled "Are there connections between the Earth’s magnetic field and climate?" published recently in Earth and Planetary Science Letters, Courtillot and co-authors attempt to cast doubt on carbon dioxide as a primary driver of recent (and presumably future) climate change; he argues instead that fluctuations in the Earth’s magnetic field (partly driven by solar variability) have an important and neglected role. Like most work of this genre, it is carried out in an intellectual void — as if everything we know currently about physics of climate had to be set aside in order to make way for one new (or in fact not-so-new) idea. But the problems don’t end there. With the help of a Comment published by Bard and Delaygue (available here at EPSL or here as pdf) , we’ll expose a pattern of suspicious errors and omissions that pervades Courtillot’s paper. Sloppiness and ignorance is by far the most charitable interpretation that can be placed on this pattern.
Rolling up the circus tent: Dispatch #7
There’s always a feeling of tristesse when they start pulling down the circus tents and loading the last of the elephants into their trailers. The last day of AGU feels a bit like that. AGU puts one much in mind of those medieval faires, or the Jokkmokk Vintermarknad, where people gathered (and still gather, in the latter case) from time to time to exchange goods and the latest news. Our own faire is a marketplace of ideas, though you can buy some nifty stuff here,too. Like a medieval faire, this is a social event as well — a time of feasting and revels, of renewing old friendships, and of making new ones. Happily, any brawls we have here are rather genteel ones.
But, it’s not over ’til it’s over especially in view of the fact that I was chairing (and giving the last talk at) the very last session of the whole shooting match — on evolution of extrasolar Large Earths. A dedicated group of extrasolar types stayed around for the fun. Closer to home, though, I dropped in on the session on Pliocene climate and the session on geoengineering.
Live (almost) from AGU–Dispatch #6
Today was the all-Union session on Tipping Points, and several people have asked for comments on what went on there. I suppose this session might have been useful for people who had to miss the more detailed discussion in specialized sections, but I don’t have much to say about most of the talks, since they for the most part went over issues like ice sheet dynamics and rapid arctic sea ice loss, which I’ve discussed in earlier dispatches. Myself, I never found the notion of “tipping points” to be a very useful contribution to public discourse. The concept is ill-defined and very prone to be misunderstood — as in: we’ve passed a tipping point so it’s too late to do anything (might as well have a party). In Hansen’s talk, he did try to clarify what he meant by a tipping point. His notion of this has less to do with what mathematicians understand as “bifurcations,” and more to do with a kind of inertia in the climate system. He means things like having passed a threshold of CO2 which, given warming in the pipeline and the lifetime of CO2, commits a certain discrete event — e.g. loss of perennial sea ice or the Amazon rainforest– to occurring even if we were to later reduce emissions to zero. He tried to distinguish between reversible and irreversible tipping points. The talk was good cheerleading, after a fashion, but rather thin on real examples of what might be a tipping point in his definition. Everything he said was true (especially the emphasis on the importance of a rapid phase-out of coal burning) but the talk had much more to do with energy policy and lamentation of the power of entrenched fossil fuel interests than it had to do with climate science.

Notes from The Gathering #5: Arctic sea ice: is it tipped yet?
The summer of 2007 was apocalyptic for Arctic sea ice. The coverage and thickness of sea ice in the Arctic has been declining steadily over the past few decades, but this year the ice lost an area about the size of Texas, reaching its minimum on about the 16th of September. Arctic sea ice seems to me the best and more imminent example of a tipping point in the climate system. A series of talks aimed to explain the reason for the meltdown.

Ptarmigans are Back! Fans of the Sheep Albedo Feedback will remember these little fellows over on the right (photo credit: Ken Tape) from the immortal paper by Squeak and Diddlesworth on the influence of ptarmigan populations on the Laurentide Ice Sheet. In Session C33A on Wednesday, Ken Tape of the University of Alaska presented a paper on the influence of ptarmigan grazing on shrubbification of the Alaskan tundra. It seems that when there is deep snow cover, ptarmigan browsing is concentrated on those few willows that stick up above the snow. They eat the buds, which inhibits willow growth. These tall willows are the ones that have managed to benefit most by climate warming, but the ptarmigan provide a stabilizing feedback, up to a point. An interesting thing is the ptarmigan don’t like to perch. 98% of the winter buds within a half meter of the snow surface get eaten, but only 48% of the buds above that browse level. So, if the shrubs grow fast enough to get above the browse level, they can beat the ptarmigans. This seems to be happening more and more.
