The effects of global climate change from greenhouse gas emissions (GHGs) are diverse and potentially very large, and probably constitute the most serious long-term environmental issue currently facing the world. This paper is prepared as task 1 of the project 'Modelling support for Future Actions - Benefits and Cost of Climate Change Policies and Measures', ENV.C.2/2004/0088, led by K.U.Leuven, Katholieke Universiteit Leuven. The paper provides a rapid review and analysis of the impacts and economic costs from climate change. The objective is to provide estimates of the benefits of climate change policy, i.e. from avoided impacts, for support to the Commission in considering the benefits and costs of mitigation efforts, and to support DG Environment in its report to the Spring Council 2005 and in future international negotiations on climate change.

An act to establish the legislative commission on global climate change: to direct the commission to study issues related to global warming, the emerging carbon economy, and whether it is appropriate and desirable for the state to establish a global warming pollutant reduction goal; and, if the commission determines that the establishment of a goal is appropriate and desirable, to authorize the commission to develop a recommended goal.

The Global Land Project (GLP) Science Plan and Implementation Strategy represents the joint research agenda of IGBP and IHDP to improve the understanding of land system dynamics in the context of Earth System functioning. This plan is therefore a first critical step in addressing the interaction between people and their environments. It is part of the broader efforts to understand how these interactions have affected, and may yet affect, the sustainability of the terrestrial biosphere, and the two-way interactions and feedbacks between different land systems within the Earth System. GLP will play a clear role in improving the understanding of regional and global-scale land systems, as well as promoting strong scientific synergy across the global change programmes. This Science Plan and Implementation Strategy develops a new integrated paradigm focused on two main conceptual aspects of the coupled system: firstly, it deals with the interface between people, biota, and natural resources of terrestrial systems, and secondly, it combines detailed regional studies with a global, comparative perspective. GLP takes as its points of departure ecosystem services and human decision making for the terrestrial environment. These topics are at the interface of the societal and the environmental domains, and serve as conceptual lenses …

In the context of this agenda item discussion took place on the management plan for the AR4 SYR. The Panel agreed that further consideration will be given by the Bureau to aspects of arrangements for management of the AR4 SYR, and progress reported to the Panel.

The meeting highlighted recent progress in the work of the IPCC, in particular the completion of the two Special Reports on Safeguarding the Ozone Layer and the Global Climate System (SROC), and on Carbon Dioxide Capture and Storage (SRCCS) and the preparations for the Fourth Assessment Report (AR4). Among other speakers, the Executive Director of the United Nations Environment Program (UNEP), Mr Klaus Töpfer addressed the Session on the linkages between science and climate change policy and the increasing need for information from the IPCC. He reaffirmed UNEP's commitment to the IPCC and supported early planning for the period beyond AR4. The Deputy Secretary-General of the World Meteorological Organization (WMO), also addressed the Panel on the importance of the principles of impartiality, transparency, scientific authority and integrity for the past success of the IPCC, the linkages of WMO programmes and IPCC assessments, and WMO's commitment to the IPCC.

Climate change and greenhouse gas (GHG) emissions are a continuing issue in the 109th Congress. Bills directly addressing climate change issues range from those focused primarily on climate change research to comprehensive emissions cap-and-trade programs. Additional bills focus on GHG reporting and registries, or on power plant emissions of carbon dioxide, as part of wider controls on pollutant emissions. The bills vary in their approaches to climate change issues. This report briefly discusses the basic concepts on which these bills are based and compares major provisions of the bills in each of the following categories: climate change research, technology deployment, GHG reporting and registries, and emissions reduction programs.
