> What is impossible about direct temperature manipulation schemes? I'm referring to proposals like building reflectors to directly lower the earth's temperature. There's nothing in principle preventing this from directly cooling the planet. I don't think anyone can name even one project of non-trivial scale that successfully controlled a natural environment. I am talking about something of the scale of a small to mid island. Something that might give support for a project hundreds of thousand, millions, tens of millions of times larger. Wanting to control anything at a planetary scale is pure hubris. C'mon. As I like to say, if we listen to the fools pushing these ideas we are far more likely to kill all life on earth than to save it. And then there are truly perplexing every-day things that provide further proof that controlling anything is hopeless. Our town is going through and repaving a bunch of streets and avenues. There's nothing --absolutely nothing-- wrong with them. I've lived here over 30 year. The streets are damn-near perfect. Just a block from my house, they tore-up about half a mile out of this avenue and replaced it with a black tar covering. Black as can be. The prior surface was mid gray. I used to take walks down that avenue. Not any more. The heat emanating from the black surface is impossible to describe. Every single street being repaved is getting the black tar treatment. How can we possibly hope to improve anything at a planetary scale when we fuck up neighborhoods just by repaving streets.
