In the race to combat climate change, the city of Los Angeles is employing a surprising new tactic — covering its streets in a grayish-white coating known as CoolSeal.
It’s sprayed onto the roadway with trucks, then spread across the surface with squeegees. However, its impact extends far beyond the edge of the pavement.
Los Angeles, like so many other modern cities, is encased in thousands of miles of asphalt. And dark-colored asphalt absorbs between 80 and 95 percent of the sun’s rays, heating up not just the streets themselves but the entire surrounding area.
By cooling the ambient air, lighter-colored asphalt can also help prevent heat-related illnesses and deaths. Its higher reflectivity can save on energy needed to illuminate streets and parking lots when the sun starts to set. And according to the EPA, the air pollution, greenhouse gas emissions and water quality depletion driven by heat islands can be mitigated by cool pavements as well.
The innovative sealcoat is admittedly very pricey, with L.A. reportedly footing a $40,000 bill for every mile it “paints.” But advocates say its benefits may just be priceless.

They'd do better to send The Moonbeam back there instead.
While I think that painting streets white to fight global warming is truly idiotic, it may have an impact on the “heat island” effect as keep a city cooler.
> Idiocy.
Not really, a white roof on large flat buildings makes quite a bit of a difference in air conditioning bills. Just have to wonder how cost effective painting streets is.
So all that white paint is going to be reflecting the suns heat back into space. Cool. On a nice hot July day you’ll walk about two or three blocks and be burnt to a crisp.
“So I’d say the idea isn’t stupid at all.”
The concept makes some sense, possibly. But, as usual with the libs in CA, their implementation didn’t work and wasted millions of dollars, instead of just building and maintaining reservoirs (a proven method).
ROTHotPavementLMAO!!!

Several people responded to me as you did. I understand that light colors reflect heat. That is simple physics. The idiocy I was referring was twofold:
1. Global Warming is a scientific hoax. If anything, the earth is cooling.
2. Even if the earth actually were warming, the notion that painting streets white is going to do anything to affect the earth's temperature is utter nonsense.
