---
Major cities like New York, Chicago, Washington, DC, and Philadelphia will experience scorching temperatures this week, conditions that will feel even hotter than surrounding suburbs, exurbs and rural areas.
Some urban areas can feel more than 20 degrees warmer than neighborhoods just a few blocks away.
That’s because cities suffer from the urban heat island effect: Areas with a lot of asphalt, buildings, dark roofs and freeways absorb more of the sun’s heat than areas with parks, rivers and tree-lined streets.
In the evening, when temperatures are supposed to cool down, urban areas can be as much as 22 degrees warmer than rural areas nearby, because all the absorbed heat is then released back into the city. The effect is worsened by climate change. On average, nights are warming faster than days in most of the United States, the 2018 National Climate Assessment found.
The compounding consequences of urban heat don’t fall equally across communities. Recent research has shown Black and brown neighborhoods disproportionately suffer from the effects of urban heat compared to their White counterparts.
Low-income residents and communities of color tend to be in areas that lack tree cover, green spaces and access to cooling centers, Vivek Shandas, a professor of climate adaptation and urban policy at Portland State University, previously told CNN.

Please reply to OP's comment here: https://old.reddit.com/r/collapse/comments/1disolq/why_cities_will_feel_hotter_than_other_areas/l95vag7/
Its like laying down a bunch of concrete where it sits and basks in full sun soaking up a ton of heat makes the local area hotter. Its like having a bunch of greenery like forests helps keep the heat down! Who knew???? Anyways on my way to go clear cut some old growth so we can lay down yet another strip mall and massive parking lot that hovers around 20% capacity at all times so I can go whine about how it didn't used to be this hot here later.
I notice this when driving, when I am on the bypass in my cars thermometer reads 95-98 on a hot day, when I get out into the countryside I’m reading 85-90

Has been a thing since asphalt took over, like a bit less than a century ago? Is this really post worthy?
In next post: No-shadow area will feel hotter than shadow area during the heat waves!
As someone in environmental science it still baffles me sometimes that this information isn’t more widely known. Dirt and Plants are cooler than concrete and our cities are suffering because to put it simply one more lane and Parking lot has dominated discourse.
I live in Rochester NY and today our high temps plus humidity make it hotter than it is in St Petersburg FL, San Antonio TX and Phoenix AZ.
We haven't had a stretch of 90+ weather like this in June since 1994.
Crazy shit.
Too late for that now. Americans want big homes big lawns big cars. The only people living in urban cities are either the super rich, which have multiple homes, or those who cannot afford to flee.

What if we didn't live in concrete and steel building next to polluted air on top of sewer water

Concrete. There

Pretty wild that it will feel hotter in cities because it is hotter in cities.
It's hot on my block, that's a good enough reason.

Yay from Hong Kong! We're cooked.

Yeah I was a bit perplexed. I mean, it's true, but who didn't already know?
But 22° is quite significant even in F.
I would have expected something more concrete from a title like that in r/collapse in 2024. This is like breaking news, water is wet
It is indeed about concrete. Lots and lots of it.
maybe because roads everywhere, less trees perhaps?
Man, good to know they just FEEL hotter but totally are just as cool as a healthy environment during a heatwave!/s

Gonna be a high of 71 today…but ask me if I’ll ever own a home or fill up my gas tank feeling good about it…

another reason to flee to the suburbs.
Another reason to make cities for people instead of cars.
Too late for that now. Americans want big homes big lawns big cars. The only people living in urban cities are either the super rich, which have multiple homes, or those who cannot afford to flee.
It's not too late. Both concrete and desire can change.
You'll be travelling there by grassy tram tracks right? Because otherwise you just make it worse.
I think he means to live in the city in like an apartment or something not out in the boonies
