The story of extreme heat in Brooklyn, New York is not unique, but Brooklyn possesses characteristics which, when combined with predictions of temperature change, make it uniquely suited to be the site of a Heat Watch Campaign. Firstly, if considered as an individual city, Brooklyn would be the third largest by population and the second most densely populated in the United States. The massive size of Brooklyn generates substantial social and economic incentive to better understand and mitigate the negative impacts of extreme heat. There are also many parts of Brooklyn where residents are at high risk of illness or death during extreme heat events- 10 out of 18 Brooklyn Community Districts are very- to severely-vulnerable to the effects of extreme heat (due to factors such as minimal green space, fewer air conditioners, and abundant heat-absorbing surfaces in those areas). Extreme variation also exists on a scale much smaller than Community District. A preliminary analysis of Landsat-8 imagery shows that land surface temperature variation around public school buildings in Brooklyn is exceptionally high- more than 10°C on a sunny day in July- creating vastly different learning environments for students in those schools. The need for detailed maps of land surface temperature in Brooklyn stems from the racial, economic, and physical diversity within the city and the amount of data necessary to create an accurate picture of the summer environment for all residents.

Campaign Goals / Anticipated Outcomes

The detailed data set created through the Heat Watch campaign will be used by multiple researchers, government agencies, and local partners working to better understand the impact of the urban heat island effect at the local level and to address community disparities in land surface temperatures and exposure to extreme heat. The campaign is also designed to further engage individuals of all ages and from all Brooklyn neighborhoods in the effort to make our city and our communities more resilient in the face of a changing climate.

About Us

NIHHIS is an integrated information system that builds understanding of the problem of extreme heat, defines demand for climate services that enhance societal resilience, develops science-based products and services from a sustained climate science research program, and improves capacity, communication, and societal understanding of the problem in order to reduce morbidity and mortality due to extreme heat.  NIHHIS is a jointly developed system by the Centers for Disease Control and Prevention (CDC) and the National Oceanic and Atmospheric Administration.
