Warmer Winter Temps May Be Tied to More Crime

Crime rates may be related to how outside temperatures affect our daily lives, according to a new study published in the journal GeoHealth. The researchers say that milder winter weather has increased regional crime rates in the United States over the past several decades.

The new findings support the theory that three major ingredients come together to bring about crime: a motivated offender, a suitable target, and the absence of a guardian to prevent a violation of the law. During certain seasons — particularly winter — milder weather conditions increase the odds that these three factors come together, and that violent and property crimes will take place.

Surprisingly, warmer summer temperatures were not linked with higher crime rates. Therefore, the new findings do not support the existing theory that hot temperatures drive aggressive motivation and behavior, according to the study’s authors. Instead, the researchers suggest that crime is related to the way climate alters people’s daily activities.

“We were expecting to find a more consistent relationship between temperature and crime, but we weren’t really expecting that relationship to be changing over the course of the year,” said Ryan Harp, lead author of the study and a doctoral candidate in the Department of Atmospheric and Oceanic Sciences at the University of Colorado Boulder.

“That ended up being a pretty big revelation for us.”

Understanding how climate influences crime could expand the boundaries of what scientists would consider to be a climate and health connection, Harp said.

“Ultimately, it’s a health impact,” he said. “The relationship between climate, human interaction, and crime that we’ve unveiled is something that will have an impact on people’s well-being.”

Earlier studies have suggested a link between temperature and the incidence of crime, but none have investigated the relationship on a regional level and only some have controlled for underlying seasonal changes, allowing researchers to identify the potential mechanism.

In the new study, the researchers conducted a systematic investigation into the link between large-scale climate variability and regionally aggregated crime rates, using a technique that allowed them to group together detailed spatial data on seasonal temperature and crime rates from across the country.

They compared crime and climate data from the Federal Bureau of Investigation’s Uniform Crime Reporting (UCR) Program and the National Oceanic and Atmospheric Administration’s North American Regional Reanalysis (NARR). The data involved 16,000 cities across five defined U.S. regions — Northeast, Southeast, South Central, West, and Midwest — from 1979 to 2016.

The finding that violent crime is almost always more commonplace when temperatures are warmer in the winter months was especially notable in areas with the harshest winters, like the Midwest and Northeast, according to the researchers.

Revealing that increasing temperatures matter more in the winter than in the summer is interesting, said Dr. Marshall Burke, assistant professor of Earth System Science at Stanford University, who was not involved with the new study.

“The authors rightly suggest that this is more consistent with warmer temperatures altering people’s patterns of activity, like going outside more, than a physiological story about temperature and aggression,” he said.
