The Second State of the Carbon Cycle Report (SOCCR2) was led and developed by the Carbon Cycle Interagency Working Group under the auspices of the U.S. Global Change Research Program. Contributing to the Fourth National Climate Assessment, SOCCR2 is designed as a special interagency assessment focused on the advances in the science and the understanding of the carbon cycle across North America since the first SOCCR (2007). Specifically, SOCCR2 focuses on U.S. and North American carbon cycle processes, stocks, fluxes, and interactions with global-scale carbon budgets and climate change impacts in managed and unmanaged systems. The report includes an assessment of the carbon stocks and fluxes in soils, water (including near-coastal oceans), vegetation, aquatic-terrestrial interfaces (e.g., coasts, estuaries, wetlands), human settlements, agriculture, and forestry. It considers relevant carbon management science perspectives and science-based tools for supporting and informing decisions. The status of and emerging opportunities for improving measurements, observations, and projections of stocks and fluxes in the carbon cycle, including uncertainty identification, are part of the report.
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 BAMS special report presents assessments of how human-caused climate change may have affected the strength and likelihood of individual extreme events. This sixth edition of explaining extreme events of the previous year (2016) from a climate perspective is the first of these reports to find that some extreme events were not possible in a pre-industrial climate.
As a key part of the Fourth National Climate Assessment (NCA4), the U.S. Global Change Research Program (USGCRP) oversaw the production of this stand-alone report of the state of science relating to climate change and its physical impacts. The Climate Science Special Report (CSSR) is designed to be an authoritative assessment of the science of climate change, with a focus on the United States, to serve as the foundation for efforts to assess climate-related risks and inform decision making about responses.
As Volume 1 of NCA4, CSSR serves several purposes, including providing (1) an updated and detailed analysis of the findings of how climate change is affecting weather and climate across the United States; (2) an executive summary and 15 chapters that provide the basis for the discussion of climate science found in the second volume of NCA4; and (3) foundational information and projections for climate change, including extremes, to improve “end-to-end” consistency in sectoral, regional, and resilience analyses within the second volume. CSSR integrates and evaluates the findings on climate science and discusses the uncertainties associated with these findings. It analyzes current trends in climate change, both human-induced and natural, and projects major trends to the end of this century. As an assessment and analysis of the science, CSSR provides important input to the development of other parts of NCA4, and their primary focus on the human welfare, societal, economic and environmental elements of climate change. Much of the underlying report is written at a level more appropriate for a scientific audience, though the Executive Summary is intended to be accessible to a broader audience.
The protocol developed and used in this report is unique in that it is an asset-level assessment of the vulnerability of infrastructure to multiple coastal hazards and climate change factors (e.g., erosion, flooding, storm surge, sea-level rise, and historical flooding) over a 35-year planning horizon (2050). The protocol was applied to all buildings and roads in Cape Lookout National Seashore; the results are summarized in the report.
This Technical Report presents results from a large set of sectoral impact models that quantify and monetize climate change impacts in the U.S., with a primary focus on the contiguous U.S., under moderate and severe future climates. The report summarizes and communicates the results of the second phase of quantitative sectoral impacts analysis under the Climate Change Impacts and Risk Analysis (CIRA) project. The effort is intended to inform the fourth National Climate Assessment (NCA4) of the U.S. Global Change Research Program (USGCRP). The goal of this work is to estimate climate change impacts and economic damages to multiple U.S. sectors (e.g., human health, infrastructure, and water resources) under different scenarios. Though this report does not make policy recommendations, it is designed to inform strategies to enhance resiliency and protect human health, investments, and livelihoods.
This report documents the efforts of seven partnerships to build resilience of natural resources in the United States. These partnerships demonstrate the benefits of using existing collaborative, landscape-scale conservation approaches to address climate change and other resource management challenges. Their goal is to build and maintain an ecologically connected network of terrestrial, coastal, and marine conservation areas that are likely to be resilient to climate change, demonstrating some ability to support a broad range of fish, wildlife, and plants under changing conditions.
As climate changes and ocean temperatures rise, the abundance, distribution, and life cycles of fish in federally managed ocean fisheries may change too. Federal agencies managing ocean fisheries have limited information to determine exactly how climate change might harm specific fish populations, and may not always understand the potential effects. To better manage climate-related risks, the report recommends (1) the development of guidance on how to incorporate climate information into the fisheries management process, and (2) finalizing Regional Action Plans for implementing the NOAA Fisheries Climate Science Strategy that incorporate performance measures for tracking achievement of the Strategy’s Objectives.
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.
This guide provides a step-by-step approach for incorporating climate change information into new or existing conservation plans in coastal environments. The guide’s six steps draw from existing strategic conservation planning frameworks, but focus on climate considerations and key resources specifically relevant to the coastal environment, including coastal watersheds.
This report features observed trend data on 37 climate indicators, including U.S and global temperatures, ocean acidity, sea level, river flooding, droughts, and wildfires. It documents rising temperatures, shifting patterns of snow and rainfall, and increasing numbers of extreme climate events, such as heavy rainstorms and record high temperatures. Many of these observed changes are linked to the rising levels of carbon dioxide and other greenhouse gases in our atmosphere, caused by human activities.
Rapidly rising seas threaten to drown tidal marshes and diminish the benefits provided to people and wildlife by these valuable coastal ecosystems. Increasingly, government agencies and non-government organizations are harnessing the power of computer-based models of marsh ecosystems to inform management and policy strategies to sustain tidal marshes. This report covers the entire modeling lifecycle, from developing a modeling approach and working with data to communicating modeling results. While some of the information pertains specifically to the northeastern United States, the report is also intended as a useful resource for modeling of marsh migration in other regions. The report is available online, with a printer-friendly version also available for download.
