Improving Characterization of Anthropogenic Methane Emissions in the United States (2018)

Understanding, quantifying, and tracking atmospheric methane and emissions is essential for addressing concerns and informing decisions that affect the climate, economy, and human health and safety. Atmospheric methane is a potent greenhouse gas (GHG) that contributes to global warming. While carbon dioxide is by far the dominant cause of the rise in global average temperatures, methane also plays a significant role because it absorbs more energ... More >>

Review of the Draft Fourth National Climate Assessment (2018)

This review from the National Academies of Sciences, Engineering, and Medicine evaluates the draft Fourth National Climate Assessment (NCA4) developed by the U.S. Global Change Research Program (USGCRP). The USGCRP is mandated by Congress to issue a national climate assessment every four years to evaluate the state of climate science and the broad range of impacts of climate change in the United States. The review concludes that the draf... More >>

Review of the Draft Second State of the Carbon Cycle Report (SOCCR2) (2018)

This review by the National Academies of Sciences, Engineering, and Medicine evaluates the draft Second State of the Carbon Cycle Report (SOCCR2) -- a report that feeds into the overall climate science assessment process developed by the U.S. Global Climate Research Program. The SOCCR2 assessment aims to elucidate the fundamental physical, chemical, and biological aspects of the carbon cycle and to discuss the challenges of accounting for al... More >>

Integrating Social and Behavioral Sciences Within the Weather Enterprise (2017)

Our ability to observe and predict severe weather events has improved markedly over the last few decades. Forecasts and warnings are being made with greater accuracy, geographic specificity, and lead time, which allows people and communities to take appropriate protective measures. Yet, as many recent hazardous weather events have illustrated, social and behavioral factors -- including people’s contexts, experiences, knowledge, perceptions, an... More >>

Review of the Draft Climate Science Special Report (2017)

The United States Global Change Research Program (USGCRP) is moving towards a sustained assessment process that allows for more fluid and consistent integration of scientific knowledge into the mandated quadrennial National Climate Assessment. As part of this process, the USGCRP is developing the Climate Science Special Report (CSSR), a technical report that details the current state-of-science relating to climate change and its physical impacts...
