This and a companion report constitute one of twenty-one Synthesis and Assessment Products called for in the Strategic Plan for the U.S. Climate Change Science Program. These studies are structured to provide high-level, integrated research results on important science issues with a particular focus on questions raised by decision-makers on dimensions of climate change directly relevant to the U.S. One element of the CCSP's strategic vision is to provide decision support tools for differentiating and evaluating response strategies. Scenario-based analysis is one such tool. The scenarios in this report explore the implications of alternative stabilization levels of anthropogenic greenhouse gases (GHGs) in the atmosphere, and they explicitly consider the economic and technological foundations of such response options. Such scenarios are a valuable complement to other scientific research contained in the twenty-one CCSP Synthesis and Assessment Products. The companion to the research reported here, Global-Change Scenarios: Their Development and Use, explores the broader strategic frame for developing and utilizing scenarios in support of climate decision making.

This report outlines a strategy for the new AOGCM/ESM modeling components in terms of aerosols/atmospheric chemistry and carbon cycle/dynamic vegetation components that are under development and implementation in ESMs that involves a proposed experimental design that integrates impacts and scenarios (represented in IPCC WG2 and WG3, respectively) and physical climate science (WG1). We summarize with a suite of recommendations for the joint WGCM, AIMES and IPCC communities.

The annual report summarized the FY2006 status of the environment and the establishment of a sound material-cycle Society in Japan. It provides an overview of Global Warming and the technologies for mitigating Global Warming. The report also describes the government's role in environmental conservation, and the formation of a sound material-cycle society.

The IPCC Panel at its 26th session called on partnerships and collaboration to address climate change, as well as a better understanding of social and economic dimensions of mitigation and adaptation. The Panel recalls its support for decoupling the climate modeling work from the emission scenario development work, in order to allow climate modelers a quick start with their work after the completion of the AR4. Also, the Panel now requests the Steering Committee on New Scenarios to prepare a few benchmark concentration scenarios through the IPCC Expert Meeting 19-22 September 2007 in Noordwijkerhout, The Netherlands. These benchmark concentration scenarios should be compatible with the full range of stabilization, mitigation and baseline emission scenarios available in the current scientific literature.

The Twenty-Seventh Session focused on the adoption and approval of the draft Synthesis Report of the IPCC Fourth Assessment Report (AR4). as indicated in the agenda, a discussion paper about the future of the IPCC was introduced, among other items that required consideration and decision by the Panel.

Monsoon Asia Integrated Regional Study (MAIRS) is an IRS research program over monsoon Asia under START and the Earth System Science Partnership (ESSP). It was established to address questions about the coupled human and environment system in the monsoon Asia region. The vision of MAIRS is to significantly advance understanding of the interactions between the human and natural components of the overall environment in the monsoon Asian region and implications for the global earth system, in order to support strategies for sustainable development. Regional-scale studies of global change provide the knowledge base for undertaking vulnerability analyses, identification of hotspots of risk and studies of environmental degradation which are crucial for the sustainable development. Regions may manifest significantly different environmental dynamics, and changes in regional biophysical, biogeochemical and anthropogenic components may produce considerably different consequences for the earth system at the global scale. Regions are not closed systems and thus the linkages between regional changes and the global earth system are crucial. This specific report focuses on Planning Workshop on MAIRS Mountain Zone Implementation that held in China. Integrated Regional Studies (IRSs) should have relevance for people living in the regions and should provide a sound scientific basis for the sustainable …

The current plan is formulated on the basis of the Outline of the 11th Five-Year Plan for the Development of National Economy and Social Development and the Decision of the State Council on the Implementation of the Scientific Outlook on Development and Strengthening Environmental Protection [No.39 document of the State Council (2005)]. The current plan is an important part of the national 11th Five-Year Plan system, and aims at expounding the objectives, tasks, investments, and key policy measures in the field of environmental protection during the 11th Five-Year Plan period. The plan identifies the responsibilities and tasks of the government and the environmental protection departments at all levels, guiding and mobilizing the participation of enterprises and civil society and striving for environmentally friendly society.
