Uncertainty and Risk

  • Uncertainty and Risk Framing Guidelines (2/10/2012)
    This document describes the steps for Author Teams to describe A) the risks (consequences and likelihood) of key vulnerabilities and B) confidence levels and uncertainties for the 3-4 most important findings in their chapter.

  • NCA Confidence Assessment Resources (2/10/2012)
    This document has been prepared as a resource for authors of the USGCRP’s National Climate Assessment 2013 Report. It describes a process that authors are requested to follow in explaining their level of confidence in 3-4 of the main conclusions of their chapters selected from among the larger set of issues they are addressing.

Sustained Assessment and Long-Term Process

  • NCADAC Sustained Assessments Workgroup White Paper
    This document explains the rationale, goal, context, and components of the sustained assessment and long term process for the National Climate Assessment and outlines the roles and upcoming activities for the NCADAC, INCA Taskforce, and NCA staff working on this topic.

International/Global Context


  • Vision for Indicators for the National Climate Assessment
    This document explains the NCA indicator vision, goals, and design criteria, and the process of establishing the NCA indicator system.

  • NCA Indicators: Background, Development, and Examples
    This report from WG 13 of the NCADAC, "Indicators development and evaluation," builds on results from three NCA workshops (5a, 5b, and 5c) to establish a rationale and lay out a framework for a set of climate-related indicators that have an end-to-end character, e.g. they will provide information on greenhouse gases, variability and change in the climate system, status and trends of important sectors that are known to be sensitive to climate variability, and response strategies. Examples of potential indicators are shown in each category.
