What do you believe is the single most important factor driving up the cost of living in Nigeria?

A new study conducted by a team of researchers from Arizona State University, University of Washington and the University of Texas at Austin reveals that extreme heat significantly alters how people go about their daily lives, influencing everything from time spent at home to transportation choices.

The study, titled "Understanding How Extreme Heat Impacts Human Activity-Mobility and Time Use Patterns," was recently published in Transportation Research Part D and underscores the urgent need for policy action as cities around the world grapple with rising temperatures.

The study provides detailed insights into how extreme heat affects daily activity-travel behavior and time use patterns for different socio-demographic groups. It draws on data from the American Time Use Survey (ATUS) and weather data from the National Oceanic and Atmospheric Administration (NOAA), focusing on 11 major U.S. metropolitan areas: Atlanta, Chicago, Dallas, Houston, Los Angeles, Miami, New York, Philadelphia, Phoenix, Seattle and Washington, D.C.

The collaborative effort emphasizes the importance of understanding the effects of extreme heat on everyday activities and mobility choices to inform policy solutions that can address growing climate challenges.
