Leadership
Dr. Gyami Shrestha is the Founder & CEO of Carboneers LLC. She is a senior earth systems leader with over 20 years of experience spanning science, policy, and data-driven strategy. Previously, she led the interagency U.S. Carbon Cycle Science Program Office under the auspices of a White House National Coordination Office, supporting multi-agency earth system science priorities, policies and coordinated funding for 11 years. She also served as a National Program Leader at the U.S. Department of Agriculture, overseeing investments in data science, artificial intelligence and emerging tech, including societal impacts. Gyami brings domain expertise, cross-sector governance experience, and a collaborative, impact-focused approach to board and advisory roles.

See Publications and Public Engagements for additional examples. The catalog below concludes with full chapters from the last U.S. Global Change Research Program (USGCRP) Assessment on carbon, the Second State of the Carbon Cycle Report (SOCCR2), which Dr. Gyami Shrestha co-led with 200+ scientists and practitioners. Since the USGCRP’s globalchange.gov, where each chapter and associated metadata were hosted and published, is no longer operational since early 2025, an attempt has been made here to maintain public access to this federally funded decadal assessment of North American carbon.

These chapters introduce the carbon cycle—what it is and why it is important. They assess the present state,
trends, and potential future directions of the North American carbon budget—the balance of carbon fluxes,
stocks, and transformations—and how this budget fits into the carbon cycle at a global scale.
Chapter 1 Overview of the Global Carbon Cycle
Chapter 2 The North American Carbon Budget
Download
These chapters highlight fluxes and processes in social-ecological systems, including urban areas, energy systems, agricultural enterprises, societal institutions, and lands belonging to Indigenous communities. The carbon cycle in these sectors is inextricably linked to human needs and actions as well as to societal decision-making outcomes.
Chapter 3 Energy Systems
Chapter 4 Understanding Urban Carbon Fluxes
Chapter 5 Agriculture
Chapter 6 Social Science Perspectives on Carbon
Chapter 7 Tribal Lands
Download
These chapters present carbon cycle fluxes and processes in different physical and ecological domains, including the atmosphere, soils, inland and coastal waters, and the coastal ocean, as well as in terrestrial ecosystems such as forests, grasslands, and those in Arctic regions. Understanding these ecosystems is fundamental to assessing and predicting net carbon sources and sinks, including feedbacks to and from the climate system. These ecosystems also represent key carbon reservoirs with sensitivity to changes in climate and atmospheric composition.

Chapter 11 Arctic and Boreal Carbon
Chapter 12 Soils
Chapter 13 Terrestrial Wetlands
Chapter 14 Inland Waters
Chapter 15 Tidal Wetlands and Estuaries
Chapter 16 Coastal Ocean and Continental Shelves

These chapters outline future projections of rising atmospheric carbon and its associated consequences. They detail how science can inform decision making at the federal, provincial, state, tribal, and local levels across North America, and how those decisions could affect the carbon cycle in the future.
