NASA Strategy For Urban Heat island NYC
Temperatures in New York City and other urban areas are typically warmer than in the surrounding countryside. A phenomenon called the urban heat island effect is the cause; air quality, public health and energy demand are all affected.

NASA researchers, using NASA satellite observations, weather pattern data and computer models, have recently assessed how well city officials, activists and community organizations are doing in reducing the effect in NYC. Their results were discussed during the 2006 American Meteorological Society’s annual meeting in Atlanta, Ga., which took place last week.
"We need to help public officials find the most successful ways to reduce the heat island effect in New York. With ever-increasing urban populations around the world, the heat island effect will become even more significant in the future," said Stuart Gaffin, an associate research scientist at Columbia University, New York, and a co-author of the new NASA study. "The summertime impacts are especially intense with the deterioration of air quality, because higher air temperatures increase ozone. That has health effects for everyone. We also run an increased risk of major heat waves and blackouts as the heat island effect raises demand for electricity."
The heat island effect in cities is caused by the non-natural heat-absorbing materials used in enormous buildings, streets, sidewalks and other public works. According to the NASA study, the heat island effect in urban areas can be most effectively reduced with more green space (vegation offers moisture to cool the air). Also, light-colored surfaces can reflect sunlight, and should be used on rooftops.
As you know, science fiction writers often take a larger view of problems. For example, in his 1970 novel Ringworld, Larry Niven had to help an entire species, the Puppeteers, sentient herd animals whose vast cities and works covered their entire planet. What can you do for a species whose entire planet is a heat island?
"I had explained," said Nessus, "that our civilisation was dying in its own waste heat. Total conversion of energy had rid us of all waste products of civilisation, save that one. We had no choice but to move our world outward from its primary."
"Was that not dangerous?"
"Very. There was much madness that year. For that reason it is famous in our history. But we had purchased a reactionless, inertialess drive from the Outsiders. You may have guessed their price. We are still paying in installments. We had moved two agricultural worlds; we had experimented with other, useless worlds of our system using the Outsider drive. In any case, we did it. We moved our world."
"In short, we found that a sun was a liability rather than an asset. We moved our world to a tenth of a light year's distance, keeping the primary only as an anchor...
