This article is part of a Special Issue on "National Indicators of Climate Changes, Impacts, and Vulnerability" edited by Anthony C. Janetos and Melissa A. Kenney Introduction Climate assessment efforts in the USA are a legally required and important process to share the state of knowledge about status and projected trends of climate changes and impacts and are used to support risk management decisions and policies (Jacobs et al. [11]). Contributions to this special issue The first paper in this special issue is I A framework for national climate indicators i (Kenney et al. [19]). In the first topical paper, I Toward an integrated system of climate change and human health indicators: a conceptual framework i (Liu et al. in preparation), the human health implications of climate change were explored to identify indicators. In I Indicators of climate change in agricultural systems i (Hatfield et al. [10]), the authors develop a conceptual framework that links the climate system to crop and livestock productivity as well as the impacts of land on other grassland and forest systems.
