Those links discuss cooling outdoor spaces. They don’t compete with awnings for keeping sunlight from warming up your house unless you plant them close enough to do so and come with a ton of downsides (roof damage, leaves clogging gutters, roots breaking pipes and foundation)…not to mention how long it takes a tree to grow tall enough to provide that sort of shade

while i don’t disagree, we should probably stop building suburbia as that would solve our problem. Suburbs completely decimate everything in the way and require replanting of the entire foliage, often leading to really shitty growth.
