Betsill has been an author or editor of 6 books. Her first book,
Cities and Climate Change: Urban Sustainability and Global Environmental Governance, was coauthored with
Harriet Bulkeley and published in 2003.
Cities and Climate Change examines the role of cities, and networks of cities, in implementing climate change policies. Betsill and Bulkeley argued that attempts to understand the implementation of climate change policies had been limited by a focus on national governments, but that meaningful policies could also be implemented at the level of city governments or non-governmental organizations, both within and across national borders and potentially without the participation of other levels of government. Focusing on the
Cities for Climate Protection program and five case studies of specific cities, Betsill and Bulkeley investigate why it is difficult for networks of cities to implement meaningful
sustainability policies in the context of
urban planning. Abby Lindsay Ostovar situated this attempt to "analyze the evolution, constitution, and meaning of the emergent system of cross-border efforts between state and nonstate actors to address climate change" in the context that state-led efforts to combat climate change have not yet been effective, prompting voluntary initiatives to attempt to fill the gap, but with as-yet unknown results. In 2008, Betsill co-founded the Earth System Governance Project, which became the world's largest network of environmental political scientists. In 2015, Betsill became the chair of the political science department at Colorado State University. A 2019 citation analysis by the political scientists Hannah June Kim and
Bernard Grofman listed Betsill as one of the most cited political scientists working at an American university in 2 different categories: the top 40 most cited women scholars, and the top 25 most cited political scientists who earned their PhD between 2000 and 2004 (inclusive).
