Los Angeles painting city streets white in bid to combat climate change

he misrepresented all of the facts in the article

even down to the color of the sealer not paint

its light gray

Then you should be able to answer my question. Why paint your engine block black?

You chickened out answering how many streets where painted white/light grey in Bermuda?
 
Its light grey


its sealer


the cost is high because its a test project


they already have to reseal roads with tar at a cost every few years


its so fucking stupid to pretend this ideas is a bad one


it will create a better,cooler street everywhere its used

its costs will greatly reduce if they decide to expand its use


and people who live on these streets will use less electricity cooling their homes


but the idiot right wing fucks hate new promising ideas

they are just that fucking lame
 
I guess I need to return the op's nickname of Havened Moron. These are the times it's pointless to try and discuss things. :palm:

You don't know if any of that is true, and I'll be very surprised if it has anything more than a marginal effect at best. What makes me laugh most though, is when you tell people that there is an urban island effect around weather stations, they attempt to dismiss it out of hand!

making my hood 10 degrees cooler in summer makes it worth it right there


fuck off

its not your home or your money dickbait
 
Never trust Havened Moron with anything on global warming, he want things to rag about, and basically is on a level of just trolling the issue. Unless he is just that dumb, that he can't even read his own sources. Him and global warming are the same as Text Drivers Are Killers, and race. The shit hit the fan years ago, and they have no integrity, or legitimacy on the issue. They are comparable to a howler monkey throwing a tantrum.

It's not even his country, and that's the real joke. Just put a troll stamp on him, since he's either distorting, or too stupid to know he's distorting.

This made me laugh, painting roofs white can actually increase temperatures.


Seemed like a cool idea: paint the world's roofs white to reflect more sunlight, and it could help cool down both cities and the planet. A new study, however, finds it's a lot more complicated – even as it dispels climate change deniers' claims that urban "heat islands" are a major cause of apparent temperature increases.

The land covered by urban areas more than doubled between 1992 and 2005, to about 0.128% of Earth's surface, Mark Z. Jacobson and John E. Ten Hoeve of Stanford University report in the Journal of Climate. Roofs and roads cover about half of that land, and help heat up urban areas by preventing evaporation of water and absorbing sunlight. Exactly how these urban heat islands affect global temperatures, however, has been unclear. But Jacobsen says some skeptics of climate science have argued that heat islands – and not the buildup of warming gases in the atmosphere – may be responsible for observed temperature increases, since some monitoring stations are near urban areas.

In a bid to get a better handle on the issue, Jacobsen and Ten Hoeve developed a model that meshed data on land use, vegetation, albedo (the reflective capacity of different land uses) and soil-type. Then, they ran two 20-year-long simulations to see how much heat islands contributed to "gross global warming" (warming before cooling factors) – and what impact a lot of white paint might have.

Overall, "the urban heat island (UHI) effect may contribute to 2-4% of gross global warming," they found, "although the uncertainty range is likely larger than the model range presented, and more verification is needed." In contrast, greenhouse gases are responsible for about 79 percent of warming, Jacobsen told the Stanford News Service, and dark particulates about 18 percent.

Jacobson says his high-resolution study – which divided the world into 1 kilometer squares — was the first to calculate the impact of urban heat islands on global sea-surface temperatures, sea ice, atmospheric stability, aerosol concentrations, gas concentrations, clouds, and precipitation. "This study accounted not only for local impacts of the heat island effect, but also feedbacks of the effect to the global scale," he says.

"A worldwide conversion to white roofs," they found, could actually warm the Earth slightly due a complex domino effect. Although white surfaces are cooler, the increased sunlight they reflect back into the atmosphere by can increase absorption of light by dark pollutants such as black carbon, which increases heating. The study, however, did not account for how white roofs might reduce electricity use for cooling, which could help lower temperatures by reducing emissions from power plants.

"Cooling your house with white roofs at the expense of warming the planet is not a very desirable trade-off," Jacobson says. "There are more effective methods of reducing global warming."

Ok Stoned Ox just how does painting streets a reflective color help solve "global warming"? I'll tell you it doesn't!
