US temperature anomalies have accelerated to 1.18°C above baseline, establishing a new persistent heat regime that threatens infrastructure and asset performance.

Over five years, US temperature anomalies have increased from 0.85°C to 1.18°C, with the sharpest acceleration occurring in 2023 when anomalies jumped to 1.17°C and remained elevated through 2025. The trend shows sustained warming above 1°C for three consecutive years, indicating a structural shift rather than temporary volatility.

If the current trend continues, US temperature anomalies will likely stabilize or drift between 1.1°C and 1.3°C over the next five years, maintaining the elevated heat regime rather than reverting to pre-2022 levels. This trajectory assumes no rapid atmospheric recovery and suggests operators should plan for persistent anomalies exceeding 1°C as the new baseline.

Power infrastructure and cooling systems face elevated stress from sustained demand spikes, while agricultural operations, water supply systems, and transportation networks built to historical temperature ranges experience increased failure risk. Insurance and real estate valuations tied to historical climate models face downside revision as the permanent heat shift reduces asset productivity and increases maintenance costs.
