Do high temperatures make us stupid? Maybe not, but this New York Times item says the heat the city is experiencing is stultifying:

"It cannot be compared to the recent record-shattering temperatures in the western United States, but still, it has been quite hot in New York City. With temperatures recorded so far today of 92 degrees in Central Park and 93 degrees at LaGuardia Airport, New Yorkers confronted a second day of stultifying heat and humidity."
