Is it time to start talking realistically about what it's going to take to cut Western environmental footprints by 75-90%? You all know what's causing climate change: meat, cars, shopping, and big, badly insulated houses. That's where the CO2 comes from. Wolf is at the door.

Don't forget ocean shipping, which produces far more emissions than cars, or the effect of aircraft contrails on global temps. The issue is globalization powered by fossil fuels. Even if everyone became vegan, rode transit and insulated their houses, it wouldn't be enough.

Wait, what?!? This needs to be looked into more.

Sulfur dioxide creates acid rain clouds, which are shiny and reflect heat from the Sun back into space. It's already been studied and is understood. The best use of this is making high altitude clouds, which produces less acid rain and stay up longer.

Cool, thanks. I was thinking of 2nd order effects. Less "is there a net cooling effect," more "is the total effect of more ships net positive for the planet?" Either way, that's an astounding finding. Thanks for bringing it up!
