Reducing greenhouse gas emissions from livestock production provides authoraitative reviews on measure GHG emissions from livestock as well as the range of methods that can be applied to reduce emissions, ranging from breeding to animal health and manure management. The collection also reviews nutritional approaches such as improving forage quality and the use of plant bioactive compounds and other feed supplements to limit emissions by modifying the rumen environment.

Even as the evidence of global warming mounts, the international response to this serious threat is coming unraveled. The United States has formally withdrawn from the 1997 Kyoto Protocol; other key nations are facing difficulty in meeting their Kyoto commitments; and developing countries face no limit on their emissions of the gases that cause global warming. In this clear and cogent book-reissued in paperback with an afterword that comments on recent events--David Victor explains why the Kyoto Protocol was never likely to become an effective legal instrument. He explores how its collapse offers opportunities to establish a more realistic alternative. Global warming continues to dominate environmental news as legislatures worldwide grapple with the process of ratification of the December 1997 Kyoto Protocol. The collapse of the November 2000 conference at the Hague showed clearly how difficult it will be to bring the Kyoto treaty into force. Yet most politicians, policymakers, and analysts hailed it as a vital first step in slowing greenhouse warming. David Victor was not among them. Kyoto's fatal flaw, Victor argues, is that it can work only if emissions trading works. The Protocol requires industrialized nations to reduce their emissions of greenhouse gases to specific targets. Crucially, the Protocol also provides for so-called \"emissions trading,\" whereby nations could offset the need for rapid cuts in their own emissions by buying emissions credits from other countries. But starting this trading system would require creating emission permits worth two trillion dollars--the largest single invention of assets by voluntary international treaty in world history. Even if it were politically possible to distribute such astronomical sums, the Protocol does not provide for adequate monitoring and enforcement of these new property rights. Nor does it offer an achievable plan for allocating new permits, which would be essential if the system were expanded to include developing countries. The collapse of the Kyoto Protocol--which Victor views as inevitable--will provide the political space to rethink strategy. Better alternatives would focus on policies that control emissions, such as emission taxes. Though economically sensible, however, a pure tax approach is impossible to monitor in practice. Thus, the author proposes a hybrid in which governments set targets for both emission quantities and tax levels. This offers the important advantages of both emission trading and taxes without the debilitating drawbacks of each. Individuals at all levels of environmental science, economics, public policy, and politics-from students to professionals--and anyone else hoping to participate in the debate over how to slow global warming will want to read this book.

In Into the Clear Blue Sky, climate scientist and chair of the Global Carbon Project Rob Jackson explains that we need to redefine our goals. As he argues here, we shouldn't only be trying to stabilize the Earth's temperature at some arbitrary value. Instead, we can restore the atmosphere itself in a lifetime--and this should be our moral duty. Restoring the atmosphere means reducing the amount of greenhouse gases in the air to pre-industrial levels--starting with super-potent methane--to heal the harm we have done. Emissions must be cut, first and foremost. But to safeguard a livable planet for future generations, we must repair the damage we have caused.

Carbon Capture and Storage, Second Edition, provides a thorough, non-specialist introduction to technologies aimed at reducing greenhouse gas emissions from burning fossil fuels during power generation and other energy-intensive industrial processes, such as steelmaking.

N2O is a powerful greenhouse gas contributing both to global warming and ozone depletion. While fungi have been identified as a putative source of N2O, little is known about their production of this greenhouse gas. Here we investigated the N2O-producing ability of a collection of 207 fungal isolates. Seventy strains producing N2O in pure culture were identified. They were mostly species from the order Hypocreales order—particularly Fusarium oxysporum and Trichoderma spp.—and to a lesser extent species from the orders Eurotiales, Sordariales, and Chaetosphaeriales. The N2O 15N site preference (SP) values of the fungal strains ranged from 15.8‰ to 36.7‰, and we observed a significant taxa effect, with Penicillium strains displaying lower SP values than the other fungal genera. Inoculation of 15 N2O-producing strains into pre-sterilized arable, forest and grassland soils confirmed the ability of the strains to produce N2O in soil with a significant strain-by-soil effect. The copper-containing nitrite reductase gene (nirK) was amplified from 45 N2O-producing strains, and its genetic variability showed a strong congruence with the ITS phylogeny, indicating vertical inheritance of this trait. Taken together, this comprehensive set of findings should enhance our knowledge of fungi as a source of N2O in the environment.

When climate scientist Joëlle Gergis set to work on the United Nations' Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report, the research she encountered kept her up at night. Through countless hours spent with the world's top scientists to piece together the latest global assessment of climate change, she realized that the impacts were occurring faster than anyone had predicted. In Humanity's Moment, Joëlle takes us through the science in the IPCC report with unflinching honesty, explaining what it means for our future, while sharing her personal reflections on bearing witness to the heartbreak of the climate emergency unfolding in real time. But this is not a lament for a lost world. It is an inspiring reminder that human history is an endless tug-of-war for social justice. We are each a part of an eternal evolutionary force that can transform our world. Joëlle shows us that the solutions we need to live sustainably already exist - we just need the social movement and political will to create a better world. This book is a climate scientist's personal guide to rekindling hope, and a call to action to restore our relationship with ourselves, each other and our planet.

We discuss connections of toroidal compactifications and Borel-Serre compactifications in view of the fundamental diagram of extended period domains. We give a complement to a work of Goresky-Tai, and generalize it to the non-classical situation. Key words: Hodge theory; moduli; toroidal compactification; Borel-Serre compactification.

Canada has been an engaged participant in global climate change negotiations since the late 1980s. Until recently, Canadian policy seemed to be driven in large part by a desire to join in multilateral efforts to address climate change. By contrast, current policy is seeking a made in Canada approach to the issue. Recent government-sponsored analytic efforts as well as the government's own stated policies have been focused almost entirely on domestic regulation and incentives, domestic opportunities for technological responses, domestic costs, domestic carbon markets, and the setting of a domestic carbon price at a level that sends the appropriate marketplace signal to produce needed reductions. A Globally Integrated Climate Policy for Canada builds on the premise that Canada is in need of an approach that effectively integrates domestic priorities and global policy imperatives. Leading Canadian and international experts explore policy ideas and options from a range of disciplinary perspectives, including science, law, political science, economics, and sociology. Chapters explore the costs, opportunities, or imperatives to participate in international diplomatic initiatives and regimes, the opportunities and impacts of regional or global carbon markets, the proper mix of domestic policy tools, the parameters of Canadian energy policy, and the dynamics that propel or hinder the Canadian policy process.

Let $k$ be an infinite field. Let $R$ be the semi-local ring of a finite family of closed points on a $k$-smooth affine irreducible variety, let $K$ be the fraction field of $R$, and let $G$ be a reductive simple simply connected $R$-group scheme isotropic over $R$. Our Theorem 1.1 states that for any Noetherian $k$-algebra $A$ the kernel of the map $$\\begin{eqnarray}H_{\\acute{\\text{e}}\\text{t}}^{1}(R\\otimes _{k}A,G)\\rightarrow H_{\\acute{\\text{e}}\\text{t}}^{1}(K\\otimes _{k}A,G)\\end{eqnarray}$$ induced by the inclusion of $R$ into $K$ is trivial. Theorem 1.2 for $A=k$ and some other results of the present paper are used significantly in Fedorov and Panin [A proof of Grothendieck–Serre conjecture on principal bundles over a semilocal regular ring containing an infinite field, Preprint (2013), arXiv:1211.2678v2] to prove the Grothendieck–Serre’s conjecture for regular semi-local rings $R$ containing an infinite field.
