Study Links Climate Change to Hotter Urban Heat Islands

Cities are hot and getting hotter, thanks to global warming and the urban heat island effect.  With urbanization on the rise globally, extreme heat threatens human health, strains energy grids, and impacts global economies around the world.

Extreme heat is now ranked as the number one weather-related killer in the United States.  With over eighty percent of Americans now living in cities, urban heat islands and record high temperatures could cause serious health problems for hundreds of millions of people during the hottest months of the year.

Climate Central just released an analysis of government records for summer temperatures in 60 U.S. cities (1970 to date).  This study found that single-day heat island differences reached 27 degrees F in some cities, and that since 2004, at least 12 cities experienced 20 additional days a year above 90°F than surrounding rural areas.

This study also ranks the top ten urban heat islands in the United States.  Washington, DC ranks number 6 on this hit parade of urban heat.

Climate Central has prepared a useful interactive tool to help you learn more.

cool urban initiatives and synoptic climatology

We at the University of Miami’s Synoptic Climatology Laboratory have just completed a study to determine how an increase in albedo and vegetation within an urban area will contribute to a healthier city. We used a novel approach: determining whether cooling associated with these urban changes will alter the air mass type over a city from one that historically leads to negative health outcomes to one that is more benign. We did determine some important improvements. To see the manuscript, please go to this site:https://www.coolrooftoolkit.org/wp-content/uploads/2014/07/Three-City-Heat-Health-Report-FINAL.pdf

UK Study Predicts 257% Jump in Heat-Related Deaths by 2050

A study recently released in London by Public Health England (PHE) and the London School of Hygiene and Tropical Medicine predicts that heat-related deaths in the United Kingdom will increase by 257% by 2050, as a result of climate change.
