I think most of us have a hard time finding anywhere to plant.
If you're not a landowner, you'll have to volunteer somewhere, but I've looked it up before and there aren't that many opportunities in my country. The organization in charge of national forests has their own staff for it.
Ironically the best way to get into it here is to join a specific local fuel station chain's "donate a cent per liter and we match, every 25 cents is a tree" community, which occasionally reaches out to members to help plant all the trees they've received donations for. So the easiest way to get to plant trees is to... buy fossil fuels???
That's a very valid point, and I'll freely acknowledge that I am privileged enough to have the space to grow and plant trees.
Keep looking for those opportunities, though! I won't pretend to know the governance of your country, but if there are public spaces in your area there must be people who administer them, and they may be open to planting more trees if the public is behind it.
To be fair, public spaces in my country already have loads of trees in most places. In my city, there's a park that doesn't get mowed because they're letting it grow into a grove. The trees are also very tall and healthy. It's goddamn beautiful. Incidentally it's also part of my commute whenever I walk (which depends on how early I manage to wake up, really)
They help significantly to combat the heat island effect in cities and provide shade and cooler microclimates for people to shelter in when it's hot.
Just try going to a shady tree-lined path vs. a paved treeless path on a sunny day and you'll be pretty clear on the meaning of this meme.
So yes we can't stop global warming with trees alone but we can mitigate the local effects of it all while providing habitat for birds and shade for people and lots of other benefits besides.
I have two potential routes for one specific part of my journey home from work. One is shaded, the other is not.
The difference in temperature I perceive is MASSIVE. Maybe the difference in air temperature isn't, but a couple of degrees difference in ambient temp + not having the sun actively microwave me adds up.
Don't discount specific area cooling from transpiration, some papers suggest anywhere from .5°C - 4°C differences in temperature when adjusted for shade
Yeah early-mid summer is about the worst time to plant. I've put plants in the ground during the summer but I'm out there watering them nearly every day when it's this hot, at least for the first few weeks.
I agree that it's a really difficult time for larger plants to establish and begin supporting themselves. One thing I've found helpful, and that I tell everyone receiving one of our plants during the season, is to water more deeply and less frequently to promote the kind of root growth that will provide better resilience during dry and/or hot periods
Locally collected seed should give you a leg up getting them growing, especially if you're overwintering and starting them with rodent protection. I don't have a positive ID on the hickories I'll be transplanting this fall but would be happy to send some if you're stateside and interested
In terms of reducing CO2 levels, yeah, but trees do also help cool down locally by simply providing shade and also because they evaporate water, which is an endothermic process.
Are you able to give it long soaking waterings, or possibly even shade it for part of the day? We've done this for some of our trees that were really affected by drought conditions two years ago with good results.
