In a 2025
New York Times opinion article, Marshall argued that climate change is already producing material impacts on households and that Americans deserve access to verified climate-risk information on home listings so they can make informed decisions to protect their financial security. In March 2025, peer-reviewed scientific journal
Global Environmental Change published an article co-authored by John Marshall and experts at
Yale University, including
Anthony Leiserowitz, who leads the
Yale Program on Climate Change Communication. The research tested the effect of three climate messages across 23 countries and found that climate change messages have the potential to strengthen public support for climate action. The
National Observer wrote about how Marshall has promoted simplifying language around climate change when speaking to the general public, such as avoiding terms like decarbonization.
Fast Company covered how Marshall has argued that statistical benchmarks, such as global temperature targets, are often ineffective in motivating broader audiences.
The Washington Post quoted Marshall on how Potential Energy’s report on electric vehicles found that abstract messaging around EVs as job creators or as a path to energy independence doesn’t work as well as pointing out how EVs cut pollution and the cost of owning a car. Marshall has also been quoted in
TIME on how companies should talk about climate change.
The Guardian noted that Potential Energy Coalition’s
Talk Like a Human guide on how to talk about climate change should be recommended reading to delegates of
United Nations Conference of the Parties (COP) conference,
politicians, business leaders,
teachers, and
journalists. John Marshall is a co-author of ''That's interesting'' newsletter, which publishes Potential Energy Coalition’s findings on climate communication. == Public Engagement ==
