Jane Holtz Kay, Predictor of Climate Change, Dies at 74 Jane Holtz Kay calculated in her 1997 book, "Asphalt Nation," that in less time than it takes you to read this sentence, Americans riding around in cars and trucks will dump another 180,000 pounds of carbon dioxide into the atmosphere - and thereby accelerate global warming and hasten the advent of catastrophic flooding in coastal cities like New York. Ms. Kay, an architecture critic who died in Boston on Nov. 5 at 74, based her prediction on government statistics and well-established scientific evidence. Her book, subtitled "How the Automobile Took Over America and How We Can Take It Back," proposed ways to reverse the environmental damage caused by suburban sprawl: by returning to the city, using public transit, living one's daily life, as much as possible, within walking distance. But, like so many other messengers, Ms. Kay said she felt like a voice crying in the wilderness. People either believed they were "powerless to do things" about the looming disaster, she told an interviewer, or were angry at her for being such a Cassandra-like scold. " "This is kind of old stuff," " she quoted them as saying. Ellen Goodman, Ms. Kay's sister and a former columnist for The Boston Globe, said Ms. Kay had grown up and raised her own children in the suburbs but decided to give up her car and move to an apartment in Boston when she began writing "Asphalt Nation" in 1991. Ms. Goodman said her sister was one to act on her ideas: "She was a big believer in doing things." She died of complications of Alzheimer's disease, Ms. Goodman said. Ms. Kay wrote three books on conservation of natural resources and urban environments. "Lost Boston" (1980) was a love letter to the many architectural treasures demolished in her native city in the rush to build roads, malls and parking spaces, and an appeal to make future changes with the human biped in mind. With Pauline Chase Harrell, she made a similar appeal in "Preserving New England" (1986). "Asphalt Nation," considered her most ambitious book, offered a unified vision for saving the cities and the planet and achieving social harmony by overthrowing the cultural dominance of the internal combustion engine. "Here at the so-called top of the food chain," she wrote, "the water we drink, the food we eat, the entire way we live, is corrupted by a toxic artifact. The car, its pollutants, its highways, its trips. The revered urbanist Jane Jacobs, the author of "The Death and Life of Great American Cities," said Ms. Kay's book had "given us a profound way of seeing the automobile's ruinous impact on American life." Jane Holtz was born in Boston on July 7, 1938, the elder of two children of Jackson and Edith Holtz. In the 1950s her father, a lawyer, twice came close to winning election as a Democrat in what was then the Republican-held 10th Congressional District in Boston. The seat has been held since 1981 by the Democrat Barney Frank, who is retiring and will be replaced in January by Joseph Kennedy III. Ms. Holtz graduated from Radcliffe in 1960, began her career in journalism at The Quincy (Mass.) Patriot Ledger, and worked for many years as an architecture critic, first for The Boston Globe and later for The Nation. In addition to her sister, survivors include two daughters, Julie Kay and Jacqueline Cessou, and four grandchildren. Until three years ago, when illness kept her from working, Ms. Kay was working a follow-up to "Asphalt Nation," called "Last Chance Landscape." Its subject was global warming, and how it was likely to change our lives sooner rather than later.
