Hydrologists (engineers interested in what happens to water) who specialize in the Great Lakes have had an interest in how climate change will affect the water levels of the Great Lakes. However, they have defied the usual practices of both the global community of hydrologists and the community of climate modelers, namely by ignoring the very important influence of the Sun on evaporation. One issue is that engineering projects involve putting a device or process in the real world and seeing it sink or swim, while in this case the relevant real world won't exist until multiple decades in the future, so it's engineers using engineering mindsets to do a non-engineering project. Methodologies used by both climate modelers and hydrologists outside of this Great Lakes group rely on principles that are more universal than what became relied upon as immutable truth within this Great Lakes group. In large measure, it became simply an issue of habit. One sentence of the book says, "I spent too much of the 2010s trying to drag this group by the nose from where they had stagnated since 1982 FORWARD to at least where the larger hydrologic community had been since 1948 and the climate modeling community had been since 1965."
