Okay I will surpass the your words "'m tired of people attacking the messenger and not the idea. They do this because they know you can't attack the idea anymore since it's proven science at this point. So they'll just attack whatever they can."
Lets take it aside and not discuss right now.
The thing, from enviromental POV which is not discussed enough is the albedo of earth, since we are building so much, the area that is just land is heavily decreasing (Shoppoing centres, new industrial parks etc) and there are lot of brownfiled that are not being used. These things absorpsh so much heat, that shoudl have been reflected back.
Then the greenhouse efect comes in a way, since the heat that is even reflected from ground level, is caught inside.
You hear here that CO2 is the main greenhouse gas etc...what a blatant lie. You should change the electricity production from coal to at least gas (NORDSTREAM II for now (until 2050 carbon neutral policy). Well guess what, when you exctract natural gas, a heavy amount of methane gets into to atmosphere (which green house effect is x time larger than the CO2).
Above everything mentioned, now west (USA, Europe, part of China)can be CO2 neutral in 2050 (It wont be, I dont think, its technically possible without big tax increases - I work in energy industry we can have a chat on that). You can tax the "rich" middle class in west, since they have the money. But the money have been made 150 years from now, because of the industrialization, thats why you are living in the best country in the world.
Now the ohter countries (India, Vietnam, Myanmar and others) want to be rich too, but somehow there is not place to do that anymore, since the enviromental policy, and basicly you are forcing them to be poor and undeveloped(not allowed to use the coal). But mainly the coal and the gas are the reasons why are we so rich in west now and they are not.
You can help them by some dontations, bulding solarsetc...but at that moment you are not developing their own sustainability, since you give them everything in there, but every piece of asset there, is not developed in the place of the use aside from the cheap labor, which is the only value they can provide to western companies.
