As you went spelunking through snowdrifts in recent days, pondering the moral necessity of pet-friendly ice melt and perhaps noting in horror the story of a Manhattan woman who froze to death hiking in subzero New Hampshire temperatures over the weekend, you were thinking about the future, defined in the moment as July. City functionaries were looking further ahead to a potentially more “Hunger Games” epoch.

Extreme weather has coincided with the release of a report by the New York City Panel on Climate Change. It isn’t the sort of thing that will leave you guiltlessly saying, “Just give me 15 minutes to pack my takeout meal and arrange my nine-irons” the next time a well-meaning venture capitalist offers you a ride on his Gulfstream to Palm Springs.

The panel, including scientists and infrastructure and risk-management experts, was established during the Bloomberg years to forecast climate trends and advise on resiliency. Its report projects that sea levels will probably rise four to eight inches in New York City in the 2020s and perhaps up to 75 inches by the beginning of the 22nd century. By 2080, mean temperature in New York City during a typical year “may bear similarities to those of a city like Norfolk, Va.,” the report states.

Other unsettling predictions (based on NASA modeling tools) abound. From 1971 to 2000, mean annual temperature in New York City was 54 degrees; by 2100, the report said, the mean temperature could be as high as 66 degrees. By the 2050s, the number of heat waves per year is expected to more than double in the city (relative to the 29-year base period between 1971 and 2000) with the number of days at or above 90 degrees reaching somewhere between 32 and 57. By the 2080s, there could be 75 days a year of 90-degree weather. And of course there is no statistical apparatus available to forecast the uptick in distemper likely to accompany these changes.
