If anyone thinks they can mix a basic cocktail let's first see them unmix a Manhatten and make it into a white russian!
Before you claim to be able to write a letter rewrite all of classic literature!
Beside we know how to fix our climate, there are several complex solutions being worked on and implemented- none of the are magic and instant so you probably won't recognize its happening until it'd almost finished.
Yeah the only catch is that it turns out humans are really good at warming planets up, and that's one of the big stumbling blocks to making Mars habitable. Reversing the process is not something humanity has ever done before. So why not turn one of our biggest bugs and turn it into a feature? Plus if we are going to experiment with intentionally changing the atmosphere of a planet I'd rather we experiment on a place where the entirety of humanity isn't currently living.
“Yes, we keep setting fires in the attic and flooding the basement. We don’t know how to stop that from happening. However, ignoring that, Carl, we are pretty sure we can figure out how to build a skyscraper across the street. And hey, if we screw it up, it’ll be across the street, not in the attic or the basement, which are still on fire and flooded. We might even figure out how to fix those by working on the skyscraper, maybe, you don’t know.”
Some people live in a lovely old rambling mansion with a busted HVAC system stuck on full blast sometimes, fires breaking out in the northwest and west wings all the time, and rising damp from a basement full of water seven feet deep and rising, but they think they should start building a new skyscraper on the empty lot across the street.
You don't understand the difference between altering a precariously balanced system which involves billions of.moving parts and starting something relatively simple from new?
