This book employs computer simulations of ‘artificial’ Universes to investigate the properties of two popular alternatives to the standard candidates for dark matter (DM) and dark energy (DE). It confronts the predictions of theoretical models with observations using a sophisticated semi-analytic model of galaxy formation. Understanding the nature of dark matter (DM) and dark energy (DE) are two of the most central problems in modern cosmology. While their important role in the evolution of the Universe has been well established—namely, that DM serves as the building blocks of galaxies, and that DE accelerates the expansion of the Universe—their true nature remains elusive. In the first half, the authors consider ‘sterile neutrino’ DM, motivated by recent claims that these particles may have finally been detected. Using sophisticated models of galaxy formation, the authors find that future observations of the high redshift Universe and faint dwarf galaxies in the Local Group can place strong constraints on the sterile neutrino scenario. In the second half, the authors propose and test novel numerical algorithms for simulating Universes with a ‘modified’ theory of gravity, as an alternative explanation to accelerated expansion. The authors’ techniques improve the efficiency of these simulations by more than a factor of 20 compared to previous methods, inviting the readers into a new era for precision cosmological tests of gravity.
"Defying all odds, governments participating in the global climate negotiations at Bali, Indonesia reached agreement on a roadmap towards a global climate change agreement to be completed by the end of 2009, ready to fill the gap when the commitments under the Kyoto Protocol expire in 2012. The contributions in this book examine some of the most difficult and controversial questions that global climate change negotiators face between now and the emergence of a 'Copenhagen Protocol' in 2009, and even beyond. Written by authoritative experts in the field, the various chapters are organised around the four principal elements in the Bali Action Plan - mitigation, adaptation, technology and financing - presented from different country, stakeholder and political perspectives."--BOOK JACKET.
The present energy economy, with its heavy dependence on fossil fuels, is not sustainable over the medium to long term for many interconnected reasons. Climate change is now recognized as posing a serious threat. Energy and resource decisions involving the carbon fuels therefore play a large role in this threat. Fossil fuel reserves may also be running short and many of the major reserves are in politically unstable parts of the world. Yet citizens in nations with rapidly developing economies aspire to the benefits of the modern energy economy. China and India alone have 2.4 billion potential customers for cars, industries, and electrical services. Even so, more than half of the world's citizens still lack access to energy. Decisions involving fossil fuels are therefore a significant part of the development equation. This volume explains how the law can impede or advance the shift to a world energy picture significantly different from that which exists today. It first examines the factors that create the problems of the present carbon economy, including environmental concerns and development goals. It then provides international and regional legal perspectives, examining public international law, regional legal structures, the responses of international legal bodies, and the role of major international nongovernmental actors. The book then moves on to explore sectoral perspectives including the variety of renewable energy sources, new carbon fuels, nuclear power, demand controls, and energy efficiency. Finally, the authors examine how particular States are, could, or should, be adapting legally to the challenges of moving beyond the carbon economy.
This book argues that government action alone will not prevent dangerous climate change, but that private governance can fill the gap.
Climate change and declining fossil fuel reserves make the current energy economy unsustainable. Developing nations aspire to the modern energy economy, yet over half the world's population still lacks access to energy. This volume explores how the law can impede or advance the shift to a significantly different world energy picture.
An assessment of policy options for future global climate governance, written by a team of leading experts from the European Union and developing countries. Global climate governance is at a crossroads. The 1997 Kyoto Protocol was merely a first step, and its core commitments expire in 2012. This book addresses three questions which will be central to any new climate agreement. What is the most effective overall legal and institutional architecture for successful and equitable climate politics? What role should non-state actors play, including multinational corporations, non-governmental organizations, public–private partnerships and market mechanisms in general? How can we deal with the growing challenge of adapting our existing institutions to a substantially warmer world? This important resource offers policy practitioners in-depth qualitative and quantitative assessments of the costs and benefits of various policy options, and also offers academics from wide-ranging disciplines insight into innovative interdisciplinary approaches towards international climate negotiations.
The world of trade is changing rapidly, from the 'rise of the South' to the growth of unconventional projects like fair trade and carbon trading. Beyond Free Trade advances alternative ways for understanding these new dynamics, based on historical, political, or sociological methods that go beyond the limitations of conventional trade economics.
In the past 25 years or more, political observers have diagnosed a crisis of the sovereign nation state and the erosion of state sovereignty through supranational institutions and the global mobility of capital, goods, information and labour. This edition of the European History Yearbook seeks to use "cultural sovereignty" as a heuristic concept to provide new views on these developments since the beginning of the 20th century.
Today, climate change is among the most hotly-debated topics. The Clean Development Mechanism (CDM), one of the three financial mechanisms under the Kyoto Protocol open to developing and developed countries, was devised to assist in mitigation of global warming. This book discusses what China should do to make full use of the CDM to promote sustainable development and to meet the challenge of climate change from a legal perspective. The findings lead to the conclusion that the CDM has limitations in promoting sustainable development in China, and thus should be regarded only as a complementary instrument in combating climate change. Legal strategies for improving the implementation of CDM projects under the legal framework in China are thus put forward, and some proposals for China to meet the challenge of climate change in the post-2012 era are made. This book offers new insights to academics and policymakers both in the public and private sector. It is intended for legal practitioners and researchers on carbon trading as well as policymakers interested in the role of developing countries in climate change law. In addition, it is of interest to stakeholders of CDM projects.
Does the diagnosis of irreversible destruction of both forests and their biodiversity actually mask a wide range of patterns? Based on the results of natural and social scientists, this book attempts to answer fundamental questions such as: what is deforestation and how do we mesure it? What changes result from deforestation and how do human societies manage these changes? It explores the many and varied aspects of deforestation, a process whose effects are not always as negative as perceived.
