    When water shortage is a concern a simple manufactured shade is a sufficient alternative. People can’t be expected to walk when it is over 40C under direct sunlight.

    Never mind shade, anyone who’s ever ridden a bicycle from the country into an urban area will instantly feel the rise in air temperature. It’s almost unbelievable, like you’ve stepped into a different planet.

    But it’s okay because cars have air conditioning. /s 😒

      100% agree. Biking in nature feels so much fresher than in the city.

      Cities are a hot oven.

        I haven’t, but is it more than the diffference between fields and forests? Though forests aren’t just shade, the trees/plants also cool themselves and their surroundings.

    I had to cut a major shade tree in my backyard, it was ready to fall over. We replaced it with a sapling and I cannot wait for it to grow up, holy shit my deck gets fucking hot! There’s a couple more that gotta go soon too and I’m very reluctant - expensive to cut down, expensive to replace, especially if they are already tall.

      Plant something that grows faster? That won’t last as long, but it should give some shade in the meantime.

      + evaporative cooling

      Edit1: Bonus points for something that would natively grow there, because you have to do less to support them once they’ve grown a bit.

      Edit2: You could decide to not fully get rid of them and instead slowly kill them. Like leaving the trunk and some big branches, cutting the rest off. Cutting off everything green that grows anew. That will still give a little bit of shade. But can also support other plants to give them hold and protect them from wind. Ivy probably can cover it with green. I don’t really know what I’m talking about.

      Edit3: Replace ivy with other native climbing plants if it’s not native in your area etc. (It’s native where I live, but it wouldn’t be native to the Americas for example)

      Plant and groom the new ones early.

      The trick with plants is generally to act like the creepiest villian asshole you can. If you dont emotionally abuse your plants, they’re not gonna be any good.

          Abuse them. Cut them to be more to your liking, starve them of water to get their roots where you want, groom them like you’re Jeffrey Epstein, emotionally abuse them, occasionally waterboard them, torture them with loud music at all times…

          And they will thrive. Its why agricultural societies jumped into depravity faster than their hunter gatherer peers; plants just need abuse.

            I struggled with some potted houseplants last year. Come winter, I assumed they’d all died so I just gave up.

            But this spring, one of the plants bounced back stronger than ever. All it took was some tender, loving neglect. It’s still thriving on my porch right now.

    Along the same lines are all the parks in my city that cut down large trees to plant small ornamental trees. Oh, want a bench? Nowhere near the trees. Yeah, I’m talking about you, Shoreline park! WTheck

    Really more than trees, it seems to be an argument for more grass to help reduce temps especially where trees aren’t feasible or will take time to grow

      Concrete surface in contact with direct noon sunlight is always gonna be scorching hot, 50°C is not far fetched. On a super hot day you can cook an egg on concrete. These surface also tend to heat up slow but also lose heat slowly, which is why even after a couple of hour after sun down it will still feel warm to the touch, creating what is known as urban heat trap.

        Dr. Hannah Fry made a short video about this recently – this kind of heat retention is why London Underground stations are so bloody hot, because the clay tiles lining the underground tunnels have absorbed heat from trains braking day in and day out and are constantly releasing excess heat into the air at the stations

          Interesting. So adding regenerative breaking to the trains would actually reduce the heat.

      The photo seems to suggest he is measuring surface temperatures, so I assume they are real. Doesn’t seem that far fetched.

      I think that’s what the guy kneeling down at the 27,9 C measurement is doing, recording the temperature of that spot.

      My doubt does come in though with the street measurement. The asphalt is cooler than the sidewalk? What? Also, did he go out into the street to take the measurement and then run back? I guess if there were no cars around he could have, but that doesn’t seem like a low-traffic area. Just a few weird things about that one detail.

        Asphalt has less heat retention capability than sidewalk bricks. The asphalt is venting more of its heat into the surroundings than the bricks are, which is why it’s cooler.

        There’s also very little traffic on his side of the street – you’ll notice there are almost no cars on that side, so it’s more than likely he had ample time to get a temperature read on the asphalt before a car came along

    Here they cut them down to make bike lanes.

    And before you demand to just take space away from the cars: this is a fast bike lane through a park. The next car is half a kilometer away.

      …that is genuinely bad planning, why would they not route the lane through somewhere there aren’t trees, like, say next to the trees?

          It originally was a single bike lane with trees. But as the amount of bikers grew and they went faster and more reckless, they had to widen it to reduce bike-bike accidents. So they had to cut down about 30 trees in the park.

          Just choose which trees wisely. Irvine CA has pines, eucalyptus and jacarandas littering the cycle lanes with cones, seed pods and branches. In general Irvine has good cycling infrastructure but there can be a lot of debris in the lane, especially after a Santa Ana wind

            Blue gum eucalyptus is probably the worst since its invasive and coming from Australia they are promote intense fires because fires is part of the regeneration of eucalyptus trees.because they produce a ton of oils , plus their allopathic, which means their leaves prevent plant growth under the trees, but
