The Technical Paper addresses the issue of freshwater. Sea level rise is dealt with only insofar as it can lead to impacts on freshwater in coastal areas and beyond. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a change in any other. Freshwater-related issues are critical in determining key regional and sectoral vulnerabilities. Therefore, the relationship between climate change and freshwater resources is of primary concern to human society and also has implications for all living species.

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 document is part of the Synthesis and Assessment Products (SAP) described in the U.S. Climate Change Science Program (CCSP) Strategic Plan. This report is meant to reduce uncertainty in projections of how the Earth's climate and related systems may change in the future. It provides scientific information for supporting the decision-making audience and the expert scientific and stakeholder community.

This Synthesis and Assessment Product (SAP 3.1) focuses on the Climate models. Scientists extensively use mathematical models of Earth's climate, executed on the most powerful computers available, to examine hypotheses about past and present-day climates. Development of climate models is fully consistent with approaches being taken in many other fields of science dealing with very complex systems. These climate simulations provide a framework within which enhanced understanding of climate-relevant processes, along with improved observations, are merged into coherent projections of future climate change. This report describes the models and their ability to simulate current climate.

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 national scientific assessment integrates and interprets the findings of the U.S. Climate Change Science Program (CCSP) and synthesizes findings from previous assessments, including reports and products by the Intergovernmental Panel on Climate Change (IPCC). It analyzes current natural and human-induced trends in global change, and projects future trends impacting the natural environment, agriculture, water resources, social systems, energy production and use, transportation, and human health. It is intended to help inform discussion of the relevant issues by decisionmakers, stakeholders, and the public. As such, this report addresses the requirements for assessment in the Global Change Research Act of 1990.1

This is a children's book where the characters build a time machine that lets them visit alternate futures based on the decisions they make in the present. The story provides a glimpse of a post-apocalyptic dystopia as a result of severe global climate change, as well as a future utopian ideal that comes as a result of implementing massive changes to land use and food and energy production.

This document is an interim committee report based on discussions from the environmental perspective what considerations Japan should abide by as a basis for international negotiations on the climate regime beyond 2012. A wide range of viewpoints are considered.

Climate change has reached the apex of the global agenda at a time when China faces significant development and energy security challenges. The political leadership and leading intellectuals are debating the direction of a new development pathway that provides both growth to meet development objectives, and dramatically reduces energy intensity and pollution. While the official position has not changed significantly, there are four key aspects that illustrate how climate change is conceived by the Chinese leadership. This signals that China may come to play a much more important role in global mitigation of climate change than was thought only a couple of years ago.

This extended report of the IPCC Expert Meeting on the Science of Alternative Metrics that was held in Oslo 18-20 March 2009 is provided in response to an invitation from the UN Framework Convention on Climate Change Ad Hoc Working Group on Further Commitments for Annex I Parties under Kyoto Protocol (UNFCCC AWG-KP) to the Intergovernmental Panel on Climate Change (IPCC) to undertake further technical assessment of alternative common metrics which are used to calculate the CO2 equivalence of anthropogenic emissions by sources, and removals by sinks, of greenhouse gases listed in Annex A to the Kyoto Protocol. The outcome of the expert meeting was an agreed set of key conclusions and recommendations to UNFCCC in response to the request of the AWG-KP as well as more specific recommendations to the scientific community regarding research needs and ones relevant to the scoping of the IPCC's Fifth Assessment Report (AR5). These were presented to the IPCC Plenary in a short report at its 30th session in Antalya, 21-23 April 2009. The current full report of the expert meeting amplifies those conclusions and recommendations and includes the extended abstracts of the meeting presentations as well as a general bibliography.

This book is the most comprehensive report to date on the wide range of impacts of climate change in the United States. It is written in plain language to better inform members of the public and policymakers. The report finds that global warming is unequivocal, primarily human-induced, and its impacts are already apparent in transportation, agriculture, health, and water and energy supplies. These impacts are expected to grow with continued climate change - the higher the levels of greenhouse gas emissions, the greater the impacts. The report illustrates how these impacts can be kept to a minimum if greenhouse gas emissions are reduced. The choices we make now will determine the severity of climate change impacts in the future. This book will help citizens, business leaders, and policymakers at all levels to make informed decisions about responding to climate change and its impacts. Likely to set the policy agenda across the US for the next few years Features examples of actions currently being pursued in various regions to address climate change. Summarizes in one place the current and projected affects of climate change in the United States

This booklet highlights key findings of Global Climate Change Impacts in the United States, a state of knowledge report about the observed and projected consequences of climate change for our nation and people. It is an authoritative scientific report written in plain language, with the goal of better informing public and private decision making at all levels. The report draws from a large body of scientific information including the set of 21 synthesis and assessment products from the U.S. Global Change Research Program, the assessments of the Intergovernmental Panel on Climate Change, and much more. It also includes new information published since these assessments were released. While the primary focus of the report is on the impacts of climate change in the United States, it also discusses some of the actions society is already taking or can take to respond to the climate challenge. These include limiting climate change by, for example, reducing emissions of heat-trapping gases or increasing their removal from the atmosphere. The importance of our current choices about heat-trapping emissions is underscored by comparing impacts resulting from higher versus lower emissions scenarios. Choices about emissions made now will have far-reaching consequences for climate change impacts, with lower …

Contrary to popular perception, ECA faces significant threats from climate change, with a number of the most serious risks already in evidence. Vulnerability over the next ten to twenty years will be dominated by socio‐economic factors and legacy issues. Even countries and sectors that stand to benefit from climate change are poorly positioned to do so. The next decade offers a window of opportunity for ECA countries to make their development more resilient to climate change while reaping numerous co‐benefits.
