  • Global Environment 1 20 Global Environment Robyn Eckersley
    CH-20: Global environment 20 Global environment Robyn Eckersley Chapter contents Introduction XXX Environmental multilateralism and the USA XXX Explaining US foreign environment policy XXX Conclusion XXX Introduction This chapter critically explores the evolution of US foreign policy on environmental issues over four and a half decades, from the Nixon administration to the Obama administration, with a brief examination of pro- spects under the new Trump administration. It shows that while the USA was widely regarded as an envi- ronmental leader during the Cold War period, it has more often than not been an environmental laggard in the post-Cold War period. The Obama administration’s reengagement in climate diplomacy stands out as a significant exception but its efforts have been rapidly wound back by the new Trump administration. The larger trend of waning environmental leadership has occurred at the same time as international environmen- tal problems, most notably climate change, have increasingly moved from the periphery towards the centre of international politics. This trend is attributed to the more challenging character of the new generation of global environmental problems that emerged in the late 1980s (particularly climate change), increasing do- mestic political polarisation on environmental issues exacerbated by an organised campaign by conservative think tanks, general concerns over economic competition with a rising powers in the global South and a gen- eral political failure to recalibrate US grand strategy in the light of the increasing threats of catastrophic global environmental risks despite increasing engagement with energy and climate security by the US mili- tary. 1 CH-20: Global environment During most of the period of the Cold War, the environment was widely regarded as a matter of ‘low poli- tics’ for state foreign policy makers as well as international relations scholars (Smith 1993).

  • Chapter Five Ecology and Political Theory Chapter 6 Is Concerned with Explanatory Social Theory; This One Is About the Encounter
    From Ecology and Society, Polity Press, 1994, Luke Martell See published book for notes and references Chapter Five Ecology and Political Theory Chapter 6 is concerned with explanatory social theory; this one is about the encounter of ecology with normative political theory. Radical greens claim that ecology constitutes a new perspective in political theory which leaves behind the older longstanding traditions. They argue that there is a green view of society and politics and that specific social and political arrangements can be argued for on green grounds. Just as there are conservative, liberal and socialist political theories and forms of social and political organization, so there is a green political theory and green forms of social and political organization. The main issue in the encounter of ecology with political theory is whether ecology does undermine traditional political theories and constitutes a new theory itself. In the light of the rise of ecology are traditional political theories put into question or how should they be altered? Does ecology constitute a new paradigm through which environmental, social and political issues can be answered on green grounds? These are important questions because they determine which theoretical perspectives can help with fundamental environmental, social and political concerns. There are two issues: (1) the implications of ecology for traditional political theory and (2) the possibility of a green political theory. 1 Ecology as revolutionary for political theory. Ecologists do bring new insights to political theory. They bring in nature in two mould-breaking ways. First, they show that there are natural limits to social and political life.

  • Tim Flannery, the Weather Makers: the History and Future Impact of Climate Change
    Tim Flannery, The Weather Makers: The History and Future Impact of Climate Change. Melbourne: Text Publishing, 2005. ISBN 1-920-88584-6 Paul Starr There are three modes of analysis in Tim Flannery’s recent climate change book: the historical, the diagnostic, and the prescriptive. The first two modes – charting the history of climate change, the history of climate science, and working out the parameters of our current predicament – take up almost all of the book. The move into prescription out of diagnosis, into what people can do to avoid or mitigate the impacts of climate change, happens in the last pages of the book, and this imbalance points to an important bind in which popular non-fiction writing about climate change for a general audience often finds itself. I will come back to this bind at the end of this review. Tim Flannery is well known in Australia, and to a lesser extent overseas, as a science- based provocateur. Earlier books based on his fieldwork in Papua New Guinea have drawn on archaeology and anthropology to explain issues such as biodiversity loss to a general audience. Books such as The Future Eaters and Throwim Way Leg contributed to popular debates on issues as diverse as the impacts of human cultures on historical ecosystems and the causes of past extinction events (such as those of Australian giant marsupials), through to the capacity of current societies to see how their behaviours contribute to, or detract from, the quality of human and non-human futures. Climate change was in many ways a new subject for Flannery.

  • Tim Flannery's
    ‘He can visualise our world in fifty years, and this vision haunts him’: Tim Flannery’s ‘Now or Never: A Sustainable Future for Australia?’1 Issue 9, December 2008 | David Hodgkinson If human beings follow a business-as-usual course, continuing to exploit fossil fuel resources without reducing carbon emissions or capturing and sequestering them before they warm the atmosphere, the eventual effects on climate and life may be comparable to those at the time of mass extinctions. Life will survive, but it will do so on a transformed planet. For all foreseeable human generations, it will be a far more desolate world than the one in which civilization developed and flourished during the past several thousand years. - Professor James Hansen, Director of the NASA Goddard Institute for Space Studies and Adjunct Professor of Earth and Environmental Sciences, Earth Institute, Columbia University2 Until a few years ago Tim Flannery was best known for his book The Future Eaters,3 an ecological history of Australia. The Future Eaters is, in part, about the subtle interaction that makes an ecosystem work. It also presents an argument for sustainability, and climate change in a sustainability context has been the focus of Flannery’s work ever since. He was the Australian of the Year in 2007. In September 2008 Flannery appeared on Enough Rope with Andrew Denton, and Denton said to him: ‘Australian of the Year is not supposed to be political in his or her comments. Was it perhaps a useful place to put you, where you couldn’t be political?’4 He responded: ‘it might have been, but I sort of made it clear on the day that I got the Award that I wasn’t going to shut up.

  • Explosive Cyclogenesis: a Global Climatology Comparing Multiple Reanalyses
    6468 JOURNAL OF CLIMATE VOLUME 23 Explosive Cyclogenesis: A Global Climatology Comparing Multiple Reanalyses JOHN T. ALLEN,ALEXANDRE B. PEZZA, AND MITCHELL T. BLACK The University of Melbourne, Melbourne, Victoria, Australia (Manuscript received 17 September 2009, in final form 23 August 2010) ABSTRACT A global climatology for rapid cyclone intensification has been produced from the second NCEP reanalysis (NCEP2), the 25-yr Japanese Reanalysis (JRA-25), and the ECMWF reanalyses over the period 1979–2008. An improved (combined) criterion for identifying explosive cyclones has been developed based on preexisting definitions, offering a more balanced, normalized climatological distribution. The combined definition was found to significantly alter the population of explosive cyclones, with a reduction in ‘‘artificial’’ systems, which are found to compose 20% of the population determined by earlier definitions. Seasonally, winter was found to be the dominant formative period in both hemispheres, with a lower degree of interseasonal variability in the Southern Hemisphere (SH). Considered over the period 1979–2008, little change is observed in the frequency of systems outside of natural interannual variability in either hemisphere. Significant statistical differences have been found between reanalyses in the SH, while in contrast the Northern Hemisphere (NH) was characterized by strong positive correlations between reanalyses in almost all examined cases. Spatially, explosive cyclones are distributed into several distinct regions, with two regions in the northwest Pacific and the North Atlantic in the NH and three main regions in the SH. High-resolution and modern reanalysis data were also found to increase the climatology population of rapidly intensifying systems. This indicates that the reanalyses have apparently undergone increasing improvements in consistency over time, particularly in the SH.
