PS: I’m an arborist who creates tree planting plans for a living, let me know if you need advice!

A few trees really don't do much. My half acre lot is a biodiverse garden covered in 3 pollinator gardens and a half dozen tree varieties but it's delusional to think that's helping with global warming. The sad reality is the big corporations are the ones doing the bulk of the damage and aren't going to stop unless we make them. They also aren't doing shit to reforest the planet.
You are wrong. Every tree planted makes a difference, so your garden does, and mine, and the gardens of people reading this thread. Let's just do both, plant more trees and stop big corporations from doing more damage.
Really, even the tiniest thing helps. Even a pot of parsley on the windowsill. Please do not give up and seed something.
I don't think we are talking about global warming, tree are very good at local climate control. The shade plus evaporation from the leaves can lower the temperature by several degrees.
In this study they observed that cities area with trees can be up to 12°C cooler than area without trees. https://www.newscientist.com/article/2298675-trees-cool-the-land-surface-temperature-of-cities-by-up-to-12c/
I currently build a house. To get a permit for the building I have to plant and maintain(!) trees in the garden for the next 20 years - one large one (like beech or maple) or two smaller ones (like pear or hawthorn) for every 200 m2 of land. Only specific locally common trees are allowed. If I don't have the trees I will be fined.
I mean that's not much but it is a start. Trees should be mandatory.
I was just looking at Google maps street view from previous years in my neighborhood. There used to be trees in front of almost every house, now it's less than half. It's really frustrating. The street used to look so much lovelier.
Get out there and talk to your neighbors! In my city we are trying to form a volunteer committee to plant trees in front yards in every neighborhood. It lowers the barrier of entry if people can have the trees planted, and if they know who to turn to for advice on care. Some local governments may have programs or arborists who can help, and others have tree planting non-profits you could try collaborating with.
Agreed! Sounds like an interesting system. Many areas require trees planted as part of development but it’s great that they specify size and a long maintenance timeline. In my area the builders have no responsibility after sale and so they plant tiny ornamental trees or inappropriate species. As a result, many new developments will never have the level of canopy needed to keep things cool.
I agree in principle, but this just sounds like hell to me.
I wish more cities would break open the pavement and plant more trees. It is notably cooler under the tree in my yard than under a parasol.
Even in my neighborhood there's tons of front yard/driveways which are fully cemented. If people would only break it open and plant something. :(
All this concrete just absorbs all the heat and keeps radiating it when it finally cools down. A bit of green in cities would do wonders ( and not just a green patch in a sea of concrete )...
Definitely! San Francisco has a program where they cut into concrete to create more space. Wish more cities were willing to be that radical.
The US needs to do green infrastructure like Australian cities.



Personally I have far higher ambitions than that... but it's certainly a start!
Now you're speaking my language!
Is that a real building or a rendering? And if it's real where is it?
Unfortunately just a render, we do have some green growth buildings like this one in Sydney but there's been a few proposed project of this sort over the last couple of years. Here's more on the rendered one.
Thanks. Unfortunately the renderings always look a little better than once its built. Growing vegetation on buildings is a cool idea but in practice it's a difficult due to the harsh environment and low soil volumes, which often lead to sick or dead plants. Hopefully they have the proper design and maintenance strategy to minimize that.
That said, this technique has a huge potential to increase greenery in cities as the article correctly points out--the vertical structure allows for more vegetation over the same footprint. Not to mention that high-rise areas of cities tend to have the least greenery of any development style, so I support any way we can squeeze it in there.
In response to a suggestion for a million tree planting campaign, one of my mentors once said we should instead aim for a trillion leaves. He was referring to the increased leaf area of larger trees, but the same applies to smaller plants that are stacked vertically like this. Trees are the most bang for your buck but I've thought about trying to develop a program to encourage green roofs, vines, and other greening of buildings because that's a lot of unused space at the moment.
I have to admit to chopping far more trees than I planted this year b-but that's only because there were already too many trees around!
No such thing! Unless maybe you’re talking about thinning to reduce fire danger.
I've seen the calculation somewhere, you'd need to plant more tress than there is surface space on earth.
It won’t solve climate change alone but every little bit helps and more importantly it will keep cities cooler to prevent mass deaths from heat.
But yes we need to both aggressively cut fossil fuel use and plant trees where appropriate.
Calculation is 1 tree = +1 shade
