To become climate resilient requires collective action. Our efforts must take a Whole-of-Government and Whole Community approach.
The Resilient Nation Partnership Network is working to address this through partnership. The result of our collective action is this Building Alliances for Climate Action resource. It is the work of many organizations and individuals, including federal representatives, faith leaders, community-based organizations, mayors and many more. At a time when many are searching for direction on how to address the climate crisis, this resource represents a unifying voice, helping guide the Whole Community forward
The Working Group II contribution to the IPCC Sixth Assessment Report assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.
This is the FY22 edition of the U.S. Gllobal Change Research Program's annual report to Congress mandated by the the Global Change Research Act. The report provides an overview of the Program’s progress in delivering on its strategic goals as well as a summary of agency expenditures under USGCRP’s budget crosscut.
This report and the accompanying community spotlights provide an overview of climate change science, reasons why action is needed, how science supports decision making and planning, ways to adapt to climate change and limit the severity of its effects, and how such efforts can help build resiliency. The report illustrates the ways in which science can help individuals, communities, businesses, and government agencies make informed decisions. By working together to identify solutions and bring about positive change, we can reduce the risks faced by current and future generations.
The Global Change Research Act of 1990 mandates that the U.S. Global Change Research Program deliver a report to Congress and the President no less than every four years that “1) integrates, evaluates, and interprets the findings of the Program…; 2) analyzes the effects of global change on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems, and biological diversity; and 3) analyzes current trends in global change, both human-induced and natural, and projects major trends for the subsequent 25 to 100 years.” The Fourth National Climate Assessment (NCA4) fulfills that mandate in two volumes. This report, Volume II, draws on the foundational science described in Volume I, the Climate Science Special Report. Volume II focuses on the human welfare, societal, and environmental elements of climate change and variability for 10 regions and 18 national topics, with particular attention paid to observed and projected risks, impacts, consideration of risk reduction, and implications under different mitigation pathways. Where possible, NCA4 Volume II provides examples of actions underway in communities across the United States to reduce the risks associated with climate change, increase resilience, and improve livelihoods. This assessment was written to help inform decision makers, utility and natural resource managers, public health officials, emergency planners, and other stakeholders by providing a thorough examination of the effects of climate change on the United States.
This special report from the Intergovernmental Panel on Climate change describes the impacts of global warming of 1.5 °C above pre-industrial levels. The report also describes potential global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.
This document provides final guidance for federal agencies on how to consider the impacts of their actions on global climate change in their National Environmental Policy Act (NEPA) reviews, providing a framework for agencies to consider both the effects of a proposed action on climate change, as indicated by its estimated greenhouse gas emissions, and the effects of climate change on a proposed action. The memorandum applies to all types of proposed federal agency actions that are subject to NEPA analysis and guides agencies on how to address the greenhouse gas emissions from federal actions and the effects of climate change on their proposed actions within the existing NEPA regulatory framework.
The National Climate Assessment assesses the science of climate change and its impacts across the United States, now and throughout this century. It documents climate change-related impacts and responses for various sectors and regions, with the goal of better informing public and private decision making at all levels.
The assessment draws from a large body of scientific peer-reviewed research, technical input reports, and other publicly available sources; all sources meet the standards of the Information Quality Act. The report was extensively reviewed by the public and experts, including a panel of the National Academy of Sciences, the 13 federal agencies of the U.S. Global Change Research Program, and the Federal Committee on Environment, Natural Resources, and Sustainability.
The Intergovernmental Panel on Climate Change (IPCC) Working Group II's contribution to the Fifth Assessment Report (AR5) relates to climate impacts, adaptation, and vulnerability. A Summary for Policymakers and the underlying scientific and technical assessment are also available.
In 2013, the Baltimore City Department of Planning and Office of Sustainability created the Disaster Preparedness and Planning Project (DP3) as an effort to address existing hazards while simultaneously preparing for predicted hazards due to climate change. This project develops an integrated All Hazards Mitigation Plan, floodplain mapping, and Climate Adaptation Plan program that links research, outreach, and actions to assure implementation of a comprehensive and new risk-preparedness system for addressing existing and future impacts. Integrating hazard mitigation planning, which focuses on past events, with climate adaptation planning, which focuses on what will likely happen in the future, offers a positive, win-win solution for Baltimore City.
This report is the Second National Climate Assessment, summarizing the science and impacts of climate change on the United States. The report discusses climate-related impacts for various societal and environmental sectors and regions across the nation. It is an authoritative scientific report written in plain language, with the goal of better informing public and private decision making at all levels.
