Direct air capture (DAC) refers to a range of technologies that capture carbon dioxide (CO2) from ambient air.

This report summarizes the current state of understanding of methane emission sources and the measurement approaches and evaluates opportunities for methodological and inventory development improvements.

This report evaluates the draft Fourth National Climate Assessment (NCA4) report to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.

This report provides an independent critique of the draft second State of the Climate Cycle Report, which aims to elucidate the fundamental physical, chemical, and biological aspects of the carbon cycle and to discuss the challenges of accounting for all major carbon stocks and flows for the North American continent.

Although terrestrial carbon sequestration regularly occurs in nature, there are human actions that can help maintain and enhance the carbon sequestration capacity of land—and help mitigate the effects of climate change.

The National Academies of Sciences, Engineering, and Medicine has developed a new infographic on the connection between extreme weather events and climate change that is based on the report Attribution of Extreme Weather Events in the Context of Climate Change.

The National Academies are establishing a new Climate Communications Initiative to coordinate efforts across the institution to facilitate rapid and effective communication of evidence-based insights to an attentive public and critical decision makers.

Watch this short animated video from the National Academies explain how the science of extreme weather event attribution is like baking cookies.

This publication summarizes the presentations and discussions from an Academies workshop in which scientists with different sets of expertise and perspectives explored potential mechanisms driving the evolution of recent Antarctic sea ice variability and discussed ways to advance understanding.

This study aims to develop a detailed research and development agenda needed to assess the benefits, risks, and sustainable scale potential for carbon dioxide removal and sequestration approaches and to increase their commercial viability.

This report reviews the U.S. Global Change Research Program’s draft Climate Science Special Report (CSSR)–a technical document intended to provide an updated, detailed analysis of how climate is changing across the U.S. and to serve as a technical input to the Fourth National Climate Assessment.

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.
