Dr. Barry Brook Inaugural Speaker in the Global Environmental Change Distinguished Speaker Series Dr. Barry Brook Inaugural Speaker in the Global Environmental Change Distinguished Speaker Series The first speaker in our “Global Environmental Change Distinguished Speaker” series will be Dr. Barry Brook. He is the Australian Research Council Future Fellow III, Sir Hubert Wilkins Chair of Climate Change, Director of Climate Science, The Environment Institute, The University of Adelaide, South Australia (Profile: http://www.adelaide.edu.au/directory/barry.brook; Blog: http://bravenewclimate.com). Barry cut his teeth as an innovative quantitative population ecologist, studying how genetic variability affects the persistence of small populations. Since then he has proliferated in many directions, with novel applications of simulation and statistical modelling to understand synergistic impacts on the biosphere. He is a terrific and wide-ranging thinker who is keen to meet with folks; please contact Scott Mills ([email protected]) or Marketa Zimova ([email protected]) to arrange a meeting time. Dr. Brook will be giving 2 presentations. All are welcome to both! FIRST TALK, part of the Forestry and Environmental Resources Seminar Series: Monday April 7, 2014, 3:30-4:30 in DANIELS 434 (*Note that this is a different room than usual*). Tipping points and metamodels: forecasting and abating aggregate human impacts on biodiversity The future of biodiversity and natural habitats in the 21st century depends on the degree to which societies decouple environmental impacts like land-use change and pollution from economic growth and rising human prosperity, and avoid crossing geophysical or biological tipping points. Top-down projections and policy scenarios typically forecast an inexorable rise in human population, land use, energy production and calorie consumption in coming decades, to the severe detriment of the biosphere. Yet, this is not inevitable—provided that various ‘technological fixes’ can be deployed, at scale, to tackle the social and fiscal drivers of environmental degradation in a timely way. This talk will show how hierarchical analysis, linked to metamodel simulations and underpinned by robust historical data, can be used to assess the feasibility of interventions. These methods hold the prospect of revealing pathways that achieve win-win outcomes for sustainable development and biodiversity conservation, at regional and global scales. SECOND TALK, more of a general public-oriented talk, April 8, 4 – 5pm. Location: 101 David Clark Labs (across from Dan Allen Parking Deck). Power to save nature? The role of nuclear energy and ‘techno-fixes’ in conserving climate and ecosystems Fossil fuels have supplied most of society’s energy demand for over two centuries. Yet, with the mounting problems of climate change, pollution, security and dwindling supplies, we now face the need for a near-total transformation of the world's energy systems. This talk will provide a critical overview of the challenges in—and potential solutions for—completely ‘decarbonzing’ our energy supplies, while also meeting the growing need for increased prosperity in the developing world. It will be argued that of the options available, it is next-generation nuclear power and related technologies, based on modular systems with full fuel recycling and inherent safety, that offer the best chance of curing our fossil-fuel addiction. Solving the ‘energy problem’ will not just help in mitigating climate change. It will also avoid destructive use of natural and agricultural landscapes for biofuels and diffuse energy generation, and allow societies to reduce their ‘footprint’ by sparing land and resources for biodiversity conservation. .

  • The Nuclear Option Why Is There a Differentiation Between the Nuclear Energy Policy of the Netherlands and Belgium?
    The Nuclear Option Why is there a differentiation between the nuclear energy policy of the Netherlands and Belgium? Name: Bo Snier (6012558) [email protected] th Date: June 20 , 2021. MA-Thesis History oF Politics and Society: Sustainability (GKMV17023) Supervisor: Dr. Hans Schouwenburg Words: 13578 1 Abstract The usage oF nuclear energy has been the subject oF much debate in the past and in the present. Even within the European Union, the use oF nuclear energy is not without complications. For eXample, Belgium is almost dependent on the use oF nuclear energy, while it is hardly used in the Netherlands. This distinction will be analyzed in this thesis, and an attempt will be made to provide an answer to the question: Why is there a diFFerentiation between the nuclear energy policy oF the Netherlands and Belgium? This matter was answered by looking at the trend that has been going on since Second World War and evaluating the actors involved in political and social debates using available source material. These actors are the government, environmental movements, the industrial sector, and scientists, in that order. According to the Findings, there is virtually little variation between Dutch and Belgian policies. The government in the Netherlands, however, made place For environmental groups and incorporated critical voices From scientists in the decision-making process. Although the Dutch government did not Follow the recommendations one-on-one, it did result in a shiFt in policy in Belgium, where these players had little or no impact on political processes; it even appeared that most scientists supported the use oF nuclear energy.

  • Prof. Barry Brook − Brave New Climate

Introduction 2. Energy options 3. Nuclear power and WMD proliferation 4. Ionising radiation and Chernobyl 5. Safety and Fukushima 6. Terra Nullius 7. Radioactive waste 8. The responsible nuclear advocate 9. Conclusion 1. INTRODUCTION This is a review of the nuclear power advocacy of Prof. Barry Brook, a conservation biology / climate change scientist/academic at Adelaide Uni who runs the Brave New Climate (BNC) website. Prof. Brook has over 170 peer-reviewed publications to his name and expertise across a range of scientific disciplines and sub-disciplines. 1 His interest in energy debates stems from his interest in and concern about climate change. He isn't in any way connected to − or in the pay of − the nuclear industry. 2. ENERGY OPTIONS Prof. Brook's view is that "it's nuclear power or it's climate change". Here is a brief outline of how greenhouse emissions can be sharply reduced without recourse to nuclear power in Australia. One of the most practical Australian studies was produced by a group of scientists for the Clean Energy Future Group (CEFG). 2 It is practical in that it makes virtually no allowance for technical innovation, restricting itself to technologies that were commercially available in 2004. It factors in official projections of economic growth and population growth. It stands at the opposite end of the spectrum to studies which make heroic assumptions about technological developments and cost reductions, and those which assume heroic reductions in energy consumption through energy efficiency and conservation.

  • Read the Open Letter to the Coal Industry
    «Salutation» «First» «Last» «Position» «Company» «Address_1» «Address_2» «City» «State» «Postcode» 29 April 2009 Dear «Salutation» «Last», We are writing to you regarding the urgent issue of climate change. We are all closely involved in producing and reviewing climate change science and are extremely concerned about the state of the global climate system. The warming of the atmosphere, driven by human-induced emissions of greenhouse gases, is already causing unacceptable damage and suffering around the world. Evidence is mounting that climate change is occurring faster than previously predicted and we are perilously close to a number of tipping points which, if passed, would amplify the effects of climate change and make it much more difficult to bring further warming under control. We cannot emphasise enough just how serious the situation has become. As you will be aware, the burning of coal is the largest contributor to greenhouse gas emissions in Australia, with more than 80% of Australia’s electricity coming from coal-fired power stations. Emissions from Australian coal-fired power stations are a small but significant contribution to total global emissions, which are directly causing sea level rise and resulting in impacts such as the flooding of coastal communities. Given the urgent need to reduce greenhouse gas emissions, immediate attention needs to be given to changing the way that we use and produce energy. The British government, recognizing the need for these changes, has just announced that no new coal-fired power stations will be built in Britain unless they capture and bury at least 25 per cent of emitted greenhouse gases immediately and 100 per cent by 2025.

  • The Nuclear Power Option: Exploring Boundaries and Limits, Asking Open Questions
    Visions for Sustainability 4: 22-42, 2015 ORIGINAL PAPER DOI: 10.7401/visions.04.04 The nuclear power option: exploring boundaries and limits, asking open questions Elena Camino1, Laura Colucci-Gray2 1Interdisciplinary Research Institute on Sustainability, Italy 2School of Education, University of Aberdeen Abstract. In this article we take up on the debate spurred by a recent paper published by Qvist & Brook on PLoS/ONE (May 2015), in which the Authors encourage ‘a large expansion of global nuclear power’. We approach the topic from a variety of perspectives, drawing on a variety of sources, in order to highlight the complexity of the issue and the social, political and educational implications of presenting the nuclear option as a plain, linear, rational choice. Adopting the paper by Qvist & brook as a ‘case in contest’ we develop a critique of conventional scientific research. We argue that for all scientific studies, authors should specify clearly and correctly the boundaries of the system under consideration which in turn, will determine the range of experimental data being collected. Results should be clearly separated from the conclusions which, in fact, are inevitably influenced by personal interpretations and collective imaginaries, which often remain unchecked. Scientists and referees of scientific journals therefore have a great responsibility when dealing with complex and controversial issues, because their voices can influence both the public and policy makers alike. By virtue of the idea, still deeply rooted in the Western world, that science describes reality, scientific evidence is deemed to 'speak truth to power'(Wildavsky, 1979). Consequently, a model of governance by numbers (Ozga, 2015) seeking to be informed by the promises of scientific certainty (Nowotny, 2015) fails to recognize the areas of uncertainty, the multiple questions which yield opportunities for disclosing alternative imaginaries and visions for sustainability.
