Search the map: How summer heat in Chicago varies by region


While other cities face increased risks of hurricanes, wildfires and droughts, climate change is projected to upend life in Chicago, largely through extreme heat and precipitation. Urban flooding is taking a toll on Chicago homeowners, especially in the south and west, but the heat is far more deadly.

Chicagoans already know that some communities are hotter than others. As the saying goes, it’s cooler by the lake. However, heat varies in a more complex way from city to city, mainly due to differences in the built environment.Mapping helps identify hotter community And it leads to a treatment that lowers body temperature.

To make local temperature trends accessible to Chicagoans, the Tribune worked with researchers at the Boston University Center for Climate Health to provide information on average summer surface temperatures and races by census block group in the city. I have created a searchable map showing. and ethnicity of the inhabitants. A block group is a cluster of blocks used by the Census Bureau to display population data. Each typically contains 600 to 3,000 people.

The map shows surface temperatures, which are more extreme than those quoted in weather forecasts. However, these measurements, collected via satellite, made it possible to analyze differences in heat exposure across cities.

The Tribune and Boston University found that Latinos disproportionately shoulder the burden of Chicago’s heat disparities, while white residents disproportionately benefited from living in areas with the coldest average temperatures. clarified. He has more than 300,000 people living in an area that’s hotter than 90% of the rest of Chicago—5 to 10 degrees above the city average, according to Census estimates. These hotter regions are mainly on the southwest side.

In Illinois, the National Weather Service issues a heat wave advisory when the combined temperature and humidity heat index reaches at least 105 degrees Celsius and is not expected to drop below 75 degrees Celsius in the evening. This advisory kicks off the city’s Emergency Management Communications Agency’s heat plan, which will phase into an alert if the heat index rises further.

City officials are facilitating the use of six official cooling centers and other air-conditioned public facilities such as libraries during the heat advisory. But the Tribune’s research partners at Boston University found that a significant portion of the city’s most vulnerable neighborhoods, with the highest average surface temperatures, had no access to public air conditioning within an 80-minute walk.

Those high need areas are shown in red on the map below. Search the map further to investigate the location of cooling resources.

The site says: Certain groups face an increased risk of heat stress for a variety of reasons, some better known than others. However, heat stroke can happen to anyone. For example, athletes and people who work outdoors are exposed to more heat than office workers. Children and the elderly are particularly vulnerable, and pregnancy and certain medical conditions also increase risk. People in low-income areas and those who are homeless are also disproportionately affected because they lack the resources to recover from heat exposure and often have greater exposure to pollutants, exacerbating the effects of heat. increase.
