Feds spread $1 billion for tree plantings among US cities to reduce extreme heat and benefit health

Because this is the vibe in the US. Only non-solutions are allowed. Don't get down or you will be kicked. No get up, only kick.

Because it shows how not solving one problem (high cost housing and the resulting homelessness) results in more problems (trees getting cut down to make it someone else's problem)

Absolutely, there can be a 20 degree C (35 degree F) difference in the same area on streets with trees vs streets without trees.

I don't know about carbon sinks, but compound-leaved trees tend to grow faster and produce dense wood.
