AI's extreme heat challenge is moving from prediction to protection
Cities and researchers are using AI to map and predict extreme heat risk, but new research suggests it's used far more to identify where people are in danger than to help officials respond. Why it matters: As climate change intensifies extreme heat, better predictions won't protect vulnerable communities unless governments can turn them into action. U.S. deaths associated with high temperatures…
The growing threat of extreme heat is prompting cities and researchers to turn to artificial intelligence (AI) to map and predict extreme heat risk. However, a new study reveals that AI is being used more often to identify vulnerable populations than to aid officials in responding to heat emergencies.
The study, published in Climate Risk Management, indicates that 98.4% of existing research on AI and machine learning in extreme heat management focuses on prediction and prevention, while only 10.4% addresses response, 3.2% recovery, and 1.6% preparedness. This research-to-implementation gap highlights the need for more effective use of AI in decision-making processes.
Karishma V. Patel, a RAND policy researcher who co-authored the study, emphasized that AI's true value lies in its ability to provide more granular predictions and scale. Cornell researcher Jennah Gosciak added that robust data systems are crucial for turning AI predictions into government action.
Google's expansion of its AI-powered Heat Resilience data to over 50 cities worldwide is a promising example. The data, which uses AI and high-resolution imagery to map roof reflectivity down to individual buildings, has already helped inform decisions in several cities, such as implementing cool-roof ordinances and adaptation plans.
However, simply having more information does not guarantee better outcomes. Gosciak compared simpler heat-vulnerability indexes with complex predictive algorithms, noting that predictive algorithms are more useful for time-sensitive decisions, while simpler indexes are better suited for long-term planning. She also pointed out the importance of explicitly choosing vulnerable populations to prioritize in heat decisions.
The future of AI in extreme heat management may lie in connecting predictions to interventions. By integrating changing signals and providing hyperlocal forecasting at granular levels, AI could help officials make near real-time decisions and better understand compound threats involving heat, air pollution, wildfire smoke, and drought. Ultimately, the goal is not just to build AI-enabled technology but to ensure it solves a problem or removes a bottleneck in heat risk management.
