Killer heat fueled by climate change could cause an additional 150,000 deaths this century in the biggest U.S. cities if no steps are taken to curb carbon emissions and improve emergency services, according to a new report. The three cities with the highest projected heat death tolls are Louisville, with an estimated 19,000 heat-related fatalities by 2099; Detroit, with 17,900, and Cleveland, with 16,600, the Natural Resources Defense Council found in its analysis of peer-reviewed data, released on Wednesday.
Concentrated populations of poor people without access to air conditioning are expected to contribute to the rising death tolls. Thousands of additional heat deaths were also projected by century's end for Baltimore, Boston, Chicago, Columbus, Denver, Los Angeles, Minneapolis, Pittsburgh, Providence, St. Louis and Washington, D.C., the report said. June, July and August are expected to see above-normal temperatures over most of the contiguous United States, from inland California to New Jersey, and from as far north as Idaho and Wyoming to Texas, Florida and the desert Southwest, the National Oceanic and Atmospheric Administration said in a May 17 forecast.
