It’s known as the “urban heat island effect,” and it refers to the pockets of intense heat captured by the concrete, asphalt, dark roofs and the dearth of foliage that define many American cityscapes.
Los Angeles Mayor Eric Garcetti wants to reduce the city’s average temperature by 3 degrees Fahrenheit over the next 20 years.

Los Angeles is the first U.S. city to test cool pavement to fight urban heat, coating streets in a special gray paint known as CoolSeal, that can lower the temperature as much as 10 degrees. The officials say that the hope is that cooler streets will lead to cooler neighborhoods, less air conditioning use and fewer heat-related deaths.
Los Angeles is one of the only cities in the nation that experiences heat-related deaths in the winter, a phenomenon expected to worsen alongside temperatures. “Not everyone has the resources to use air conditioning, so there’s concern that some low-income families will suffer,” says Alan Barreca, an environmental science professor at the UCLA. “That bothers me on a moral dimension. The pavement would provide benefits to everyone. “It can protect people who have to be outdoors,” he added.
The coating costs about $40,000 per mile and lasts seven years, officials said. To determine whether CoolSeal is cost-effective and how it influences drivers, Spotts said his agency has applied the product to designated streets in 14 of the city’s 15 council districts, where it will be monitored and studied through the fall.
Rather than applying oil based paints to the roads and letting them wash away into the ocean when it rains why not invest in lighter colored asphalt surfaces? Bonus you get a new road, less heat, longer lasting surface, AND less lighting needed because the surface is more reflective (reducing light pollution and energy consumption). Further - invest in porous asphalt surfaces (zoab) that recharge groundwater rather than taking everything to the sea. All of this has already been developed and implemented in Europe!

Can we stop spraying the skies with the chemtrails aka "geoengineering" which blanket the skies, trapping in heat like a greenhouse?
Politicians always have a Problem: Reaction: Solution to sell us.

Important to note - this is a small-scale test. NPR's Morning Edition had a small story on this and made sure to mention that they will be measuring the life cycle environmental costs and weighing the benefits the test may or may not find against them. At first glance it appears that the LA streets department's environmental division know what they're getting themselves into.
