This workshop was designed to address a key issue for the USGCRP’s National Climate assessments: providing information about climate-related hazards, risks, and opportunities in formats that are understandable, credible, and useful to decision makers in their efforts to reduce greenhouse gas emissions and to reduce vulnerability and increase resilience to climate change in the regions or sectors for which they are responsible.

This report summarizes the presentations and discussions from a September 2015 workshop convened to examine variability in Earth’s climate on decadal timescales. During the workshop, ocean and climate scientists reviewed the state of the science of decadal climate variability and its relationship to rates of human-caused global warming, and they explored opportunities for improvement in modeling and observations and assessing knowledge gaps.

A new report from the National Academies’ Board on Science, Technology, and Economic Policy asks an important question: rather than trade affordability and reliability for low emissions, is there a way to balance all three?

The impact of aerosols on the atmosphere is widely acknowledged as one of the most significant and uncertain aspects of climate change projections. At the request of the Intelligence Community, the National Academies held a classified workshop in September 2015 that brought together scientists from the civil and intelligence communities to determine the usefulness of …

This report identifies priorities and strategic steps forward for atmospheric chemistry research for the next decade. A major goal is to develop improved predictive capability that foresees environmental changes and societal impacts to inform policy and other decisions.

Video and slides from the release briefing on the new report, Attribution of Extreme Weather Events in the Context of Climate Change, are now available online.

Currently, the accuracy, skill, and scope of extended weather forecasts (those made two weeks to 12 months in advance) is limited. This report presents the vision that, in the next decade, subseasonal to seasonal forecasts will be as widely used as short-term weather forecasts are today.

This new educational resource from the National Research Council’s Polar Research Board is a reader-friendly primer on how the changes currently affecting the Arctic and its diverse people, resources, and environment can, in turn, affect the entire globe.
