What would we do without experts?
Study: If we painted every rooftop in 100 major cities white, it would offset the entire planet’s carbon dioxide emissions for one year.

A side bonus is that you wouldn’t see a trace of pigeon shit.
Excellent, John! Also, after several years, the shit would act as an insulator, saving even more energy!
But..that’s not right. If you paint stuff white then all that light gets reflected back up into the atmosphere where it heats up those tiny CO2 molecules.
I mean isn’t that what the AGW people say..its the radiation coming up from the earth that is absorbed by CO2.
Now I am confused. Maybe its all BS
Wait how about the cost of mining megatonnes of titanium diooxide pigment?
And the loss of solar gain at high latiitudes leading to burning more fuel to stay warm in winter
and…
More drivel on energy efficiency. You folks are right to be skeptical of this twit. In Canada, the furnace is on about nine months of the year. Its heating load is offset to some degree by the absorbed heat from the black shingled roof. So, paint your roof white and you get reduced heat for three months when it helps reduce air conditioning demand, and hinder for nine months when it will increase the furnace load. The same argument applies, by the way, to the stupid ban on incandescent light bulbs.
Remember, if it comes from California by definition it’s a silly idea.
Oh, and sustainablog or whatever that waste of electrons is called can’t even get the institution name right. It’s the Lawrence Livermore National Laboratory, not “Lawrence Berkeley National Laboratory”.
Kind of reminds me of this one:

C’mon, now be nice. He gets beat up enough on his own comments page…:^))
Speaking of bullshit, it’s the fourth anniversary of Dan Rather’s “Bush National Guard scoop” which comically ended his own career instead of that of the intended victim. Went to the well once too often and finally got caught.

“Repaving roads with lighter-colored materials would have a similar impact to painting rooftops.”
How bout for “lighter-coloured materials” we use all those useless environmentalist skulls; or are they too green?
Painting roads white must make sense lefty minimalist art deco peabrains. Once they drain all the color from the TransCanada highway’s asphalt, they can show us how to drive semi-trucks across the Prairies during a heavy January snowfall at night.
They may find out that the seemingly wide lanes aren’t as wide as they appear. I can only imagine headlight glare
I recently read an article where Walmart will be putting a white plastic membrane on all their roofs to reflect heat. The figure they’ll save money by not having to air condition as much.
…white? I’m partial to blue.
richfisher: Environmentalists’ skulls are too soft for road paving. However, they’d make a nice petroleum-free substitute for bubble wrap.

Double duty.

But Kathryn…..what happens to all that hot air when we pop them???
tenski,
Reflected light would pass through the atmosphere in without heating up much of anything. Light has to be absorbed by something, then re-radiated at a shorter wavelength, in the IR part of the spectrum, to be absorbed by molecules in the atmosphere. So painting your roof white wouldn’t cause more heating. It might cool your house a little depending on the white paint you use. Some white paint reflects well, some absorbs a fair amount of light, causing the underlying surface to gain heat. That’s why the old Stevenson Screens that the weather stations use have to be coated with whitewash, not oil or acrylic paint.
Its still a goofy idea though and I’m sure that the greens would figure out a way to stop it even if they did want to do it in the first place. The only acceptable solution to our catastrophic situation is to get rid of all technology and return to the dark ages. Of course we’d have to keep a few private jets for the leaders of the new world order to fly around in.

Thanks for the clarification.
IMAGINE THIS. You paint every roof of every house and building of every major city in N. America using a standard paint. On the last can of paint, you notice the following words on the side of the label. CAUTION; CONTAINS LEAD
Enjoy!!!
What the hell is going on here–my comments aren’t showing up. What am I, a Liberal or something??
…are you typing white font on white background?
😉
Actually, I was using black letters on charcoal “blackground.” Just kidding!!
I think they should go to Africa and paint all the n…..agh..Mmmmmmm…gaaa….well lets just say I’m white and that can be considered the superior colour in this case:-)))))
