Report Identifies 71 Metrics for Monitoring Climate Change

Monitoring Climate Change Impacts: Metrics at the Intersection of the Human and Earth Systems, a new report from the National Research Council, identifies 71 metrics that when taken together may give advance warning of climate-related changes and their impacts across a range of local and global scales.

Currently, many observing systems capture elements of how climate is changing, such as direct measurements of atmospheric and ocean temperature. However, these measurements do not provide information about the impacts, particularly those that affect humans, that are especially relevant for political and economic planning and decision making. The report lays out an illustrative suite of indicators, metrics, and measurements -- and locations worldwide where they can be applied -- that are important for understanding global climate change and providing insight into environmental sustainability. These metrics include sea-level rise, seasonal snow cover, and air quality.
