Abstract: Humid heat across subtropical-to-tropical regions is rarely extreme, yet it remains dangerous—persisting across diurnal cycles for weeks to months at a time. Because of its lack of extremity, this form of heat danger is frequently underrecognized in climate analysis research and adaptation planning (including communication strategies). This work utilizes remote sensing and observational data across a seasonally wet and muggy region to explore and examine thermal patterns for: 1) better understanding potential unique patterns for heat in humid regions; 2) informing tools and methods for better capturing heat hazards across humid regions; and 3) informing relevant adaptation strategies. Results show the need for an improved understanding of place-specific heat stress metrics and thresholds, as well as improved urban cooling mechanisms that account for the impact that increased air moisture can have on the surface and the human body.

Bio: Nkosi Muse is an Environmental Fellow at Harvard University's Center for the Environment. With a background in meteorology (B.S., UNC Charlotte), his research identifies climate hazards, particularly humid heat hazards at lower latitudes, and also informs his adaptation policy writing and analysis (PhD, Environmental Science and Policy, University of Miami). Applied across all of this work is a climate and environmental justice lens to equitably recognize exposures and vulnerabilities, as well as propose and implement solutions.
