School of Economics and Honors College University of Maine http://umaine.edu/soe/faculty-and-staff/tisher/ Copyright © 2019 All Rights Reserved Sharon S. Tisher A Climate Chronology: International Policy, U.S. Policy, and Science The most challenging of all endeavors in human history will likely be that of understanding the impact of our industrial and technological enterprises on the planet’s climate and ecosystems, and responding effectively to the threats posed by that impact. I began writing this chronology while developing a climate policy course at the University of Maine. It has grown substantially during the ensuing seven years, and continues to grow. By juxtaposing developments in climate science, U.S. policy, and international policy over the previous century, I hope to give the reader new insights into where we have been, where we are now, and where we may be headed in this formidable endeavor. I welcome comments, and suggested additions to this evolving work. It will be updated every January. I owe thanks to George Criner, for asking me to develop the climate policy course; to my University of Maine students, game to explore these turbulent waters and mindful of their import for their lives; to my daughter Annya Tisher, who joined me at the Boston Women’s March with the sign, “Climate Change Matters.” 19th Century overview Humans begin to replace wood and other biomass fuels with a readily available fossil fuel: coal; coal fuels the Industrial Revolution. Humans in parts of Europe and the United States replace the biomass fuels such as wood and peat that had served Homo sapiens for hundreds of thousands of years with coal, a highly energy- intensive fossil fuel. Machine technology and the corporate form of business organization— punctuated by passage of the British Limited Liability Act of 1855—facilitate both the extraction of coal and the deployment of energy to reshape civilization’s infrastructure and way of life. U.S. consumption of fossil fuels surpasses that of wood in the early 1880’s. During the second half of the 19th century, the average U.S. per capita supply of all energy increases by 25%; utilization of coal increases by a factor of ten.* * Vaclav Smil, Energy at the Crossroads: Global Perspectives and Uncertainties (Cambridge: MIT Press, 2005), 1. 20th Century overview Oil and gas join the arsenal of high-energy fossil fuels, spurring rapid global land, sea, and air transport; total energy consumption worldwide experiences unprecedented growth, most dramatically in the United States Oil and gas make new modes of rapid global land, sea, and air transportation possible. Coal is the predominant fuel in the production of electricity. Total energy consumption worldwide experiences unprecedented growth. Between 1900 and 2000, consumption of fossil fuels rises almost fifteenfold. As scientist and policy analyst Vaclav Smil notes,“[I]n spite of the near quadrupling of global population—from 1.6 billion in 1900 to 6.1 billion in 2000—average annual per capita supply of commercial energy more than quadrupled from just 14 GJ [gigajoules] to roughly 60 GJ…” United States residents are far and away the largest consumers of energy. Between 1900 and 2000, annual per capita energy supply in the United States more than triples to about 340 GJ per capita, or more than five times the global average.* * Vaclav Smil, Energy at the Crossroads: Global Perspectives and Uncertainties (Cambridge: MIT Press, 2005), 2. 1824 French mathematician and physicist Jean Baptiste Joseph Fourier first hypothesizes that the atmosphere plays a significant role in mediating temperature on Earth Fourier, in the article “General Remarks on the Temperature of the Earth and Outer Space," likens the effect of the Earth’s atmosphere in regulating global temperature to a glass covered box: “The temperature [of the Earth] can be augmented by the interposition of the atmosphere, because heat in the state of light finds less resistance in penetrating the air, than in re-passing into the air when converted into non-luminous heat.” This analogy would ultimately inspire the term “greenhouse effect.”* *Joseph Fourier, "Remarques Générales sur les Températures Du Globe Terrestre et des Espaces Planétaires."

He also offers a rich collection of photographs of key players, graphs, and other illustrations at http://history.aip.org/climate/illus.htm. 1856 A paper is presented at the annual meeting of the American Association for the Advancement of Science by American scientist Eunice Foote predicting the warming impact of “carbonic acid” (carbon dioxide) on the atmosphere. Foote describes an experiment where she filled separate glass jars with water vapor, carbon dioxide, and air and then measured how they heated up in the sun: “The highest effect of the sun’s rays I have found to be in the carbonic acid glass… The receiver containing the gas became itself much heated — very sensibly more so than the other — and on being removed, it was many times as long in cooling.” Foote goes on to consider what this might mean for our atmosphere: “An atmosphere of that gas would give to our earth a high temperature,” she wrote, “and if as some suppose, at one period of its history the air had mixed with it a larger proportion than at present, an increased temperature from its own action as well as from increased weight must have necessarily resulted.” These findings were presented in a paper titled “Circumstances affecting the heat of the sun’s rays” on August 23, 1856 at the annual meeting of the American Association for the Advancement of Science (AAAS). Foote was able to have her paper presented because her husband, Elisha Foote, was a member of the organization. As reported in ThinkProgress, “She did not present her own work, however. Instead, Professor Joseph Henry of the Smithsonian Institute, spoke on her behalf. In acknowledging that it was Foote’s work, Henry introduced the findings by stating, ‘Science was of no country and of no sex. The sphere of woman embraces not only the beautiful and the useful, but the true.’” As Texas Tech climate scientist Katherine Hayhoe told ThinkProgress, due to the rudimentary set-up of the experiment, Foote “wasn’t measuring what she thought she was measuring, but she actually serendipitously ended up with an understanding that is correct today… She very presciently speculated that the temperature of the planet would be higher if CO2 were higher and as far as I know she was the first person to speculate that.” Hayhoe noted that she didn’t have enough information to be able to say whether John Tyndall [see 1861] was aware of Foote’s work when he published his better known work five years later.* *Kyla Mandel, “This woman fundamentally changed climate science — and you’ve probably never heard of her,” ThinkProgress, May 18, 2018, https://thinkprogress.org/female-climate-scientist-eunice-foote-finally-honored-for-her-contributions-162-years-later- 21b3cf08c70b/ 1861 Irish physicist John Tyndall demonstrates experimentally that water vapor and other gases warm the atmosphere John Tyndall, in the article “On the Absorption and Radiation of Heat by Gases and Vapours, and on the Physical Connexion of Radiation, Absorption, and Conduction,” reports on an experimental apparatus to demonstrate and measure the heat trapping impact of atmospheric gases. His later comment underscores his surprise at this discovery: "Those who, like myself, have been taught to regard transparent gases as almost perfectly diathermanous (transparent to heat), will probably share the astonishment with which I witnessed the foregoing effects….I was indeed slow to believe it possible that a body so constituted, and so transparent to light as olefiant gas, could be so densely opake to any kind of calorific (infrared) rays; and to secure myself against error, I made several hundred experiments with this single substance."* In 1862, Tyndall provides the following analogy: “As a dam built across a river causes a local deepening of the stream, so our atmosphere, thrown as a barrier across the terrestrial rays, produces a local heightening of the temperature at the Earth’s surface.”** In his 1863 book Heat Considered as a Mode of Motion, Tyndall notes the importance of this finding for conditions amenable to life on earth: “Aqueous vapour [water vapor] is a blanket, more necessary to the vegetable life of England than clothing is to man. Remove for a single summer night the aqueous vapour from the air which overspreads this country, and you would assuredly destroy every plant capable of being destroyed by a freezing temperature. The warmth of our fields and gardens would pour itself unrequited into space, and the sun would rise upon an island held fast in the iron grip of frost.”*** * Richard Black, “Tyndall’s climate message, 150 years on,” BBC News, September 28, 2011, http://www.bbc.com/news/science- environment-15093234

  • Paleontology1
    PALEONTOLOGY1 Thoreau’s firm grasp of paleontology laid the groundwork for the climax of WALDEN, which describes the emergence of complexity and beauty from the simple flow of muddy sand at the Deep Cut. It also was the taproot of his lifelong frustration with Christian supernaturalists, who insisted on a fairly brief history of life. Paraphrasing Lyell’s PRINCIPLES, he jested [in A WEEK ON THE C ONCORD AND M ERRIMACK R IVERS]: “It took 100 years to prove that fossils are organic, and 150 more, to prove that they are not to be referred to the Noachian deluge.” Not everyone believes this, even today. Modern “young Earth” creationists still insist that the Elizabethan-era Mosaic chronology of Archbishop Ussher is the correct one, and that we twenty-first century scientists are in error. — Professor Robert M.

  • When Does a Social Problem Become a Legitimate Issue on the Media
    Movement-Countermovement Dynamics in the Global Warming Policy Conflict Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By James Everett Hein, M.A. Graduate Program in Sociology The Ohio State University 2012 Dissertation Committee: J. Craig Jenkins, Co-Advisor Andrew Martin, Co-Advisor Edward Crenshaw ii Copyright by James Everett Hein 2012 iii Abstract In a provocative paper, Michael Shellenberger and Ted Nordhaus (2005) shook the environmental establishment by declaring that environmentalism had died, claiming that the movement pushing for global warming policies had failed because of their framing strategy. A content analysis of pro-global warming policy movement frames deployed in the New York Times from 1981 through 2003 shows support for their claim that the frames were largely technocratic and lacked linkages to larger American values. However, their claim that the movement has framed global warming as solely an environmental problem is not supported by the data. The pro-global warming policy movement first focused their frames on prognostics, or in other words the causes and consequences of the social problem, but after the issue arrived on the international governmental agenda in 1988 the movement’s frames shifted focus to diagnostic frames, or solutions to global warming. Examination of countermovement frames shows that frame debunking fell into two categories: prognostic attacks and diagnostic attacks. The countermovement responded with diagnostic attacks when it mobilized in 1989 and in the 1990s gradually deployed prognostic attacks in equal numbers. Zero-inflated poisson regressions were used to test the sociopolitical factors accounting for frame deployment for both the movement and countermovement.

  • 2016 United Nations Climate Change Conference (COP22/CMP12) Thunder Bay, Canada
    2016 United Nations Climate Change Conference (COP22/CMP12) Thunder Bay, Canada Background and Briefing Notes (for March 18, 2016) This exercise in Geog. 3331 provides a brief history of world positioning and a framework of geopolitical considerations likely to affect progress in the critical area of climate change negotiations. The goal is to simulate a global discussion of climate change policy with Multilateral Negotiations between Parties (in this context - countries represented by students in the classroom). There is an overwhelming scientific consensus that the major cause of global warming is an increase of greenhouse gases such as carbon dioxide and methane from human activities. This enhancement of the greenhouse effect", where heat radiated by the Earth is absorbed and sent back to the surface by the greenhouse gases in the atmosphere, has resulted in a substantial rise in the average global temperature. The current average is 1.5° C higher than the estimated global temperature in pre-industrial times, which means considerably more energy available in the hydrological cycle and other processes. More frequent storms, hotter summers and an increase in flooding have driven up the global insurance industry’s annual weather-related losses to $200B a year according to Lloyd's of London – a fourfold increase in 30 years. Zurich Re and the Canadian Insurance Board (for Canada 4x) have similar estimates. The United Nations Framework Convention on Climate Change (UNFCCC) was adopted unanimously at a Rio de Janeiro conference in 1992 (the “Rio Earth Summit). The Convention committed to stabilize greenhouse gas concentrations "at a level that would prevent dangerous anthropogenic interference with the climate system" and put the onus on developed countries to lead the way.

Basic Radiation Calculations The foundation of any calculation of the greenhouse effect was a description of how radiation and heat move through a slice of the atmosphere. At first this foundation was so shaky that nobody could trust the results. With the coming of digital computers and better data, scientists gradually worked through the intricate technical problems. A rough idea was available by the mid 1960s, and by the late 1970s, the calculations looked solid—for idealized cases. Much remained to be done to account for all the important real-world factors, especially the physics of clouds. (This genre of one-dimensional and two-dimensional models lay between the rudimentary, often qualitative models covered in the essay on “Simple Models of Climate” and the elaborate three-dimensional “General Circulation Models of the Atmosphere.”) Warning: this is the most technical of all the essays.

Tisher Foreword to A Climate Chronology Dr. Sean Birkel, Research Assistant Professor & Maine State Climatologist Climate Change Institute School of Earth and Climate Sciences University of Maine March 12, 2021 The Industrial Revolution brought unprecedented innovation, manufacturing efficiency, and human progress, ultimately shaping the energy-intensive technological world that we live in today. But for all its merits, this transformation of human economies also set the stage for looming multi-generational environmental challenges associated with pollution, energy production from fossil fuels, and the development of nuclear weapons – all on a previously unimaginable global scale. More than a century of painstaking scientific research has shown that Earth’s atmosphere and oceans are warming as a result of human activity, primarily through the combustion of fossil fuels (e.g., oil, coal, and natural gas) with the attendant atmospheric emissions of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and other * greenhouse gases. Emissions of co-pollutants, such as nitrogen oxides (NOx), toxic metals, and volatile organic compounds, also degrade air quality and cause adverse human health impacts. Warming from greenhouse-gas emissions is amplified through feedbacks associated with water vapor, snow and sea-ice

  • How to Proceed After Copenhagen
    How to Proceed After Copenhagen Jan Kunnas European University Institute, Florence , Italy Introduction In 2007, the Nobel Peace Prize was awarded to the Intergovernmental Panel on Climate Change (IPCC), the global body responsible for scientific assessment of climate change, and Al Gore, the panel’s most renowned campaigner. With this decision, the Norwegian Nobel Committee highlighted the link between the risk of accelerating climate change and the risk of violent conflict and wars (Smith, 2007). Climate change was also among the justifications for awarding the same prize to US President Barack Obama two years later (Smith, 2009). In his Nobel lecture, President Obama stated that the world must come together to confront climate change: “There is little scientific dispute that if we do nothing, we will face more drought, more famine, more mass displacement – all of which will fuel more conflict for decades” (Obama, 2009a). The election of Barack Obama as the President of the United States had raised high hopes for a comprehensive new climate treaty to succeed the Kyoto Protocol expiring in 2012. This hope was reinforced in July, 2009 at the G8 Summit in L’Aquila where the G8 leaders, including President Obama, recognized the scientific view on the need to keep global temperature rise below two degrees Celsius above preindustrial levels (G8 Leaders Declaration, 2009). A strong commitment by the United States would remove the major excuse for China not to move ahead. China´s President Hu Jintao had recently reaffirmed that they will not commit to mandatory emissions-reduction targets before the world's wealthy countries take the lead in addressing global climate change.

  • 2. Implementing Carbon Taxes to Reduce Greenhouse Gas Emissions
    West Lake Model United Nations 2019 Hangzhou International School, Hangzhou, China Forum: General Assembly 2 Issue: Implementing carbon taxes to reduce greenhouse gas emissions Student Officer: Christopher Han Position: President Introduction Currently, there are more emissions of greenhouse gases than there ever were before. Emitting those gases have environmental consequences, such as global warming, climate change, and health consequences to people. However, carbon taxes are levied on emissions of these greenhouse gases and incentivizes stakeholders to switch to alternatives whose production involves less carbon emission. However, due to this novel concept as well as disadvantages the carbon tax has, not a lot of countries have this implemented. This report will guide delegates to propose methods that can increase the implementation of carbon taxes in order to more effectively reduce greenhouse gas emissions. Definition of Key Terms Carbon Taxes A tax per unit of carbon emissions of fossil fuels. It is considered by many countries as a policy to deal with climate change (Tragakes) Greenhouse gases (GHGs) Gases that can absorb infrared radiation/heat, that was emitted from the Earth’s surface and can radiate it back to Earth’s surface (Mann). Examples of GHGs include water vapor, carbon dioxide, methane, nitrous oxide, ozone, etc. (Rouse). Research Report | 1 West Lake Model United Nations 2019 Hangzhou International School, Hangzhou, China Greenhouse Effect The exchange of incoming and outgoing radiation that relies on GHGs to trap heat in the Earth’s atmosphere. It is the natural global warming. Without the greenhouse effect, the temperature of Earth would be at a temperature where it is too cold for humans to live in (Lallanila).

  • Theoretical Physics Takes Root in America: John Archibald Wheeler As Student and Mentor
    AN ABSTRACT OF THE THESIS OF Terry M. Christensen for the Degree of Master of Science in History of Science presented on June 12, 2006 Title: Theoretical Physics Takes Root in America: John Archibald Wheeler as Student and Mentor Abstract approved: Signature redactedfor privacy. /\ U I Mary J0 Nye, Ph.D. John Archibald Wheeler (09 July 1911 ) is a familiar name to physicists and historians of physics alike. Among his many contributions to the corpus of knowledge, in 1939 John Wheeler and Niels Bohr co-authored the first paper on the generalized mechanism of nuclear fission. Beyond that seminal work, Wheeler was a key player in the production of the 'Fat Man' plutonium weapon in the Manhattan project, and later, in the development of the Hydrogen Bomb. Wheeler introduced the scattering matrix (or S-matrix) to account for all possible final quantum states of collisions between nucleons. After turning his attention to general relativity, Wheeler and his students made a number of significant contributions to cosmology and cosmology. In fact, John Wheeler coined the term "black hole," and developed the concepts of a "Planck Length," a Planck-time," "quantum foam," and "wormholes" in space-time. Outside the physics community however, considerably less is known about John Wheeler as a mentor of physicists. Mentoring is important because, while there can be no progress in physics without contributions to the corpus of knowledge, these contributions are, by their very nature additive. In contrast, the contributions of skilled mentors such as John Archibald Wheeler are multiplicative through a number of intellectual generations. Until quite recently, studies of mentoring in science were limited to 'laboratory' and/or 'field' disciplines such as chemistry and the life sciences.

    Forthcoming in Agnotology: The Cultural Production of Ignorance, edited by Robert Proctor and Londa Schiebinger, Stanford University Press. Challenging Knowledge: How Climate Science Became a Victim of the Cold War1 Naomi Oreskes and Erik M. Conway The Scientific Consensus on Climate Change On June 2, 2005, California Governor Arnold Schwarzenegger announced an initiative to curb greenhouse gas emissions in California as a step towards addressing global warming. In his speech, the governor declared, “The debate is over. We know the science. We see the threat, and we know the time for action is now.”2 Schwarzenegger had his science right: the scientific debate is over. In fact, it has been for some time. Since the early-mid 1990s, there is a consensus in the scientific community about the basic facts of global warming, which is why the Inter-governmental Panel on Climate Change (IPCC) is able to say with assurance that most of the warming observed over the last 50 years is attributable to human activities.3 What scientific knowledge lies behind this statement? First, that humans have changed the chemistry of the Earth’s atmosphere, most notably by changing the concentration of carbon dioxide from a pre-industrial revolution level of about 280 parts per million to its current level of 385 and rising. (For his systematic work on the measurement of atmospheric CO2 since 1958, Charles David Keeling 1 Forthcoming in Agnotology: The Cultural Production of Ignorance, edited by Robert Proctor and Londa Schiebinger, Stanford University Press. won the 2002 National Medal of Science.) Second, that this carbon dioxide is largely the result of the massive burning of fossil fuels—coal, oil, and gas—since the industrial revolution.4 Third, that carbon dioxide is a greenhouse gas, meaning that it is highly transparent to visible light and less so to infrared, so if you change its concentration, it affects the radiative balance of the atmosphere.
