This paper discusses several key areas where U.S. policy should be reshaped, both domestically and internationally, to ensure we lead the world towards a safe, sustainable future. We should: Establish a price for carbon by adopting an ambitious 2020 emissions reduction target. Make investments and adopt policies to stimulate a green economy. Lead the world toward an effective and equitable global climate agreement Support efforts to stop emissions from deforestation and degradation in developing countries. Contribute to global financing mechanisms for climate mitigation and adaptation in the developing world. Ensure that climate change-related impacts are addressed under the Endangered Species Act. Improve science and information to prepare communities and ecosystems for unavoidable climate change. Build public support for sustained action to fight climate change

This report critically reviews current knowledge about global distributions and properties of atmospheric aerosols as they relate to aerosol impacts on climate. It assesses possible steps to substantially reduce uncertainties in aerosol radiative forcing estimates.

This report discusses the current state of understanding about the characteristics and implications of uncertainty related to climate change and variability to an audience of policymakers, decision makers, and members of the media and general public with an interest in developing a fundamental understanding of the issue.

This document is part of the Synthesis and Assessment Products described in the U.S. Climate Change Science Program (CCSP) Strategic Plan. The U.S. Government's CCSP is responsible for providing the best science-based knowledge possible to inform management of the risks and opportunities associated with changes in the climate and related environmental systems. To support its mission, the CCSP has commissioned 21 "synthesis and assessment products" (SAPs) to advance decision making on climate change-related issues by providing current evaluations of climate change science and identifying priorities for research, observation, and decision support. This Synthesis and Assessment Product (SAP), developed as part of the U.S. Climate Change Science Program, examines potential effects of sea-level rise from climate change during the twenty-first century, with a focus on the mid-Atlantic coast of the United States. Using scientific literature and policy-related documents, the SAP describes the physical environments; potential changes to coastal environments, wetlands, and vulnerable species; societal impacts and implications of sea-level rise; decisions that may be sensitive to sea-level rise; opportunities for adaptation; and institutional barriers to adaptation.

This document contains a draft version of how the agreement in Copenhagen could look like – in legal form. This is very much a work in progress. The purpose of this exercise is two fold : a) to outline to Parties how the agreement could fit together substantively and b) to demonstrate that the two Protocol option is a feasible and desirable outcome for the legal form. Attempts have been made through provisions in both the proposed Copenhagen Protocol and the amendments to the Kyoto Protocol to unify the accounting, reporting and verification of as well as compliance with emission reduction targets for industrialized countries and to create a forum for these bodies (CMCP & CMKP) to jointly develop rules in the future. It is possible that not every T has been crossed or i dotted and further provisions or amendments linking the two may be required.

This Synthesis and Assessment Product focuses on the connection between the scientific ability to predict climate on seasonal scales and the opportunity to incorporate such understanding into water resource management decisions. It directly addresses decision support experiments and evaluations that have used seasonal-to-interannual forecasts and observational data, and is expected to inform (1) decision makers about the relative success of experiences of others who have experimented with these forecasts and data in resource management; (2) climatologists, hydrologists, and social scientists on how to advance the delivery of decision-support resources that use the most recent forecast products, methodologies, and tools; and (3) science and resource managers as they plan for future investments in research related to forecasts and their role in decision support. It is important to note, however, that while the focus of this Product is on the water resources management sector, the findings within this Synthesis and Assessment Product may be directly transferred to other sectors.

This Climate Change Science Program Synthesis and Assessment Product addresses current capabilities to integrate observations of the climate system into a consistent description of past and current conditions through the method of reanalysis. In addition, the Product assesses present capabilities to attribute causes for climate variations and trends over North America during the reanalysis period, which extends from the mid-twentieth century to the present. This Product reviews Past Climate Variability and Change in the Arctic and at High Latitudes. Paleoclimate records play a key role in our understanding of Earth's past and present climate system and in our confidence in predicting future climate changes. Paleoclimate data help to elucidate past and present active mechanisms of climate change by placing the short instrumental record into a longer term context and by permitting models to be tested beyond the limited time that instrumental measurements have been available. Recent observations in the Arctic have identified large ongoing changes and important climate feedback mechanisms that multiply the effects of global-scale climate changes. As discussed in this report, paleoclimate data show that land and sea ice have grown with cooling temperatures and have shrunk with warming ones, amplifying temperature changes while causing and responding to …

This Report (SAP 4.2) focuses on the thresholds of Climate Change in Ecosystems. As defined in this Synthesis and Assessment Report, 'an ecological threshold is the point at which there is an abrupt change in an ecosystem quality, property, or phenomenon, or where small changes in one or more external conditions produce large and persistent responses in an ecosystem'.Ecological thresholds occur when external factors, positive feedbacks, or nonlinear instabilities in a system cause changes to propagate in a domino-like fashion that is potentially irreversible. This report reviews threshold changes in North American ecosystems that are potentially induced by climatic change and addresses the significant challenges these threshold crossings impose on resource and land managers. Sudden changes to ecosystems and the goods and services they provide are not well understood, but they are extremely important if natural resource managers are to succeed in developing adaptation strategies in a changing world. The report provides an overview of what is known about ecological thresholds and where they are likely to occur. It also identifies those areas where research is most needed to improve knowledge and understand the uncertainties regarding them. The report suggests a suite of potential actions that land and resource managers …

The document contains key facts about climate change drawn from UNDP's 2007/2008 Human Development Report. The document also outlines UNDP's work in the area of climate change and provides examples.

In June 2006, Québec established its first climate change action plan that set ambitious goals and established the means to achieve them. Entitled QUÉBEC AND CLIMATE CHANGE: A Challenge for the Future, the 2006–2012 Climate Change Action Plan was a major step on the road to a society where sustainable development is at the core of priorities and collective choices. The government is now moving forward by improving the action plan with new measures and additional funding. The revised action plan allows Québec to maintain its position as a North American leader in the fight against climate change.

This first biennial report of the Climate Neutral Working Group (CNWG) is being issued as required by Executive Order #14-03, signed by Governor James Douglas in September 2003. It is intended to give a brief introduction to the environmental, economic, and social risks that climate change poses to Vermont. It aims to provide a clear summary of the ongoing energy consumption and greenhouse gas (GHG) emissions inventory of Vermont State Government operations. In addition, the report includes potential emission reduction strategies, energy consumption case studies, and other relevant work conducted by the CNWG since the signing of the Executive Order regarding Climate Change.

This proceedings provides possible answer to the question of what social network analysis can contribute to addressing the problem of climate change. In the workshop, social scientists from Japan, the USA, and Europe reported on social network theory, applications and methodology to envision their use for on-the-ground social change regarding carbon management. The earth has always cycled carbon in the atmosphere (mainly as CO2); in the oceans (surface, intermediate waters, deep waters and marine sediments); in terrestrial ecosystems (vegetation, litter and soil); in rivers and estuaries; and in fossil carbon, which is being remobilized by human activities. However, with the rate of fossil fuel burning feeding industrialization, urbanization and transportation and with large scale land clearing, the naturally balanced carbon cycle is in a non-analogous and dangerous state. The participants agreed that current management of the carbon cycle is piecemeal, careless, inconsistent, profligate and shortsighted. Enabled by past and current networks of power, the world has embraced a carbon culture that has spun out of control in the past 100 years. This issue has often been referred to as a problem of scale in the climate change research community (or frames in the social science community). Climate researchers have focused …
