small changes make a BIG difference (C)

Two photos: a side-by-side comparison of residential streets in a big city. The first shows cars parked next to apartment buildings on a street without trees. Air temperature is shown as 40°C, and ground temperature is shown as 46°C. The second picture shows a similar street with cars parked next to buildings, but this time with a canopy of large trees. Air temperature is shown as 32°C, and ground temperature as 34°C.

@breadandcircuses Maintenance costs,tree pruning,leaf sweeping etc?

@DJHVII @breadandcircuses A street gains so much more from those trees than money can express.

Sun damage to paint, cars, pavement, increased air conditioning costs, medical costs from extreme heat. Are you serious?

@Osteopenia_Powers @DJHVII @breadandcircuses Trees are good. No trees is bad. I am pro tree. The 'pruning costs' outweigh the benefits of having trees.

At a moment in time when we are losing topsoil, tree leaves are a good thing. We need mulch. We need compost. We need messy trees.

@DJHVII @breadandcircuses that's not a cost, it's a benefit. It creates an employment opportunity which will boost the local economy.

@breadandcircuses We'll have to do large awnings, too, or even completely cover streets in some cases.

@breadandcircuses I can personally attest to this truth. I am recently semi retired and set up a wood working bench under the trees at the edge of where I live next to a pasture sometimes populated by cows. The walk across the yard in the middle of the day here in TN in the summer is HOT. Once I get to the trees it instantly feels cooler. It may still be humid, but it IS cooler immediately. We need more trees everywhere!

@breadandcircuses

Just cycling beside a woodlot after being out in open farmland one gets a reprieve of 3-4 degrees.

Every bush and tree is natural solar-powered a/c at work.

And for those curious, that temperature drop is quite real—and far less from the shade provided than from that vegetation drawing down solar energy and storing it in hydrocarbon form.

Imagine a large tree burning top to bottom - that’s the heat energy captured and stored in a single one of them.

@f800gecko @breadandcircuses In my youth it was always a reprieve from the hot hay/grain field work to spend the day in the woodlot getting firewood for winter. The work was just as strenuous, but the air was cooler. Downside were the deer flies that sting like hell when they bite.

@breadandcircuses I think about this every time I walk/run in the neighborhood near my apartment with almost zero sidewalk shade. Meanwhile those homeowners happily water their sterile grass yards.

I think the only way to change these suburban hellscapes (that shouldnt exist) is by lowering their estimated house price. Maybe through low "walkability scores" for no shade?

Beautiful neighborhoods have big trees with kissing canopies.

Next step: Replace some asphalt with soil. And there are another handful of centigrades less in average.

@byteborg @breadandcircuses

Smaller roads are a good start. We don’t need four lane wide city streets, which are ugly, loud & car centric. I’d love for cities to invest in beautiful, clean, free public transportation.

Some cities have been playing with asphalt. Changing the color to decrease heat.

@breadandcircuses Put white or aluminum flake paint on black roofs and install white sheet roofing when it's time to replace. This increases roofing lifetime and keeps buildings cooler. And unlike trees, reflective roofs send solar radiation back into outer space. Dark surfaces absorb light, heat up, and emit infrared. A significant part of that infrared is trapped by atmospheric global warming gases.

Also, some really hot cities are painting pavement with white paint for the same reason.

@breadandcircuses and if you ride your bicycle through that tree shaded road it will be even cooler: 10°C or more. A little wind is a lot of ventilation and cooling.

Green is the key. Green trees and especially green kelp and seaweed. Much more important than green $$.

@breadandcircuses @gregatron5 there’s not enough talk about city and residential regulation to increase the albedo of roads and roofs. Black asphalt roads and dark roofs should be banned.

@breadandcircuses

I feel it when biking around. It's the primary reason I try to take side streets as much as possible instead of stroads. The biking distance is the same (or even longer) on the side streets, but it's less physically taxing because of the shade.
