At this NASEM workshop, participants discussed the science and applications drivers for BL observation, emerging technology to improve observation capabilities, and strategies for the future.

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

This new publication summarizes a webinar and workshop that addressed direct air capture of carbon dioxide (CO2), which refers to a range of technologies that capture CO2 from ambient air.

This report evaluates the draft Fourth National Climate Assessment 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.

A new committee on carbon dioxide removal and reliable sequestration will develop a research and development agenda to assess the benefits, risks, and sustainable scale potential for carbon dioxide removal and sequestration approaches.
