**B: Sunk Costs Because Climate Research Is Irreversible — What Users Are Learning in the U.S. Today** In a world where climate change is no longer a future threat but an unfolding reality, one pressing reality stands out: some investments—once made—cannot be undone. The growing recognition of *sunk costs* in climate research reflects a deeper shift in how individuals, communities, and institutions confront irreversible changes. As data accumulates and impacts intensify across the U.S., the cost of delayed action is becoming harder to ignore. What does it mean to grapple with these irreversible investments, and how are public conversation, science, and policy evolving in response? The term “sunk costs” typically describes spending resources—time, money, effort—that cannot be recovered. In climate research, these costs manifest not in individual dollars lost, but in the irreversible changes already underway: rising temperatures, shifting weather patterns, and escalating natural disasters. As flooding, wildfires, and droughts become more frequent and severe, society faces the hard truth that some outcomes, once triggered, cannot be reversed—only adapted to and mitigated. A growing awareness of these irreversible stakes is fueled by accessible climate data and real-world consequences. More Americans are engaging with research that reveals how early warnings were punctuated by action—or inaction—so today’s decisions carry heavier weight. The realization that past investments in observation, modeling, and mitigation now define the scope of future resilience has sparked both concern and curiosity. For many, this shift marks a turning point: understanding sunk costs is no longer just about economics or science, but about personal, community, and national accountability.
