Simonwalcal said "I hate that it's become so popular to look to the moon/Mars/ elsewhere as a means to escape the hell on earth that is predicted. For a couple reasons:
1.) If humans don't adjust the overall ideology that led us to the point of no return in the first place, then we're just kicking the can down the road. We could find a planet 50 times the size of the earth . . .
2.) I fear that colonies will be a playground (or escape spot) for only the privileged few that can pay the top dollar to Elon in order to make the trip. Leaving the rest of us with what's left.
I don't doubt the Hawking assertion that we're in for a world of trouble. My eyes tell me that. Where I disagree is the response.
If the rich want to build a Las Vegas of sorts on the Moon and/or Mars . . . FINE. Let's just not focus everything in that direction.
I don't know if it's possible to artificially suck 3 generations worth of CO2 out of the atmosphere. I don't know what ramifications THIS would have. Since there are still CFC's and HFC's floating around from past technological advances, I don't know how long they would delay the process until they are broken down.
I just want people to be asking these questions, doing the research. Instead of focusing on what should be a non-starter.

spend trillions of dollars to terraform or build colonies on Mars as our future home when we could of spent that money to cleanup Earth really would say something about humanity. If we get to that point, we are screwed as a species.
Right now we seem more intent on recovering as much oil as fast as we can and screw our climate. Don't you dare impede the oil industry in any way or propose any alternatives to oil. And yes, that may change how we do things, our products, our lives. But as we have seen through human history, we adapt. There's no reason why we can't adapt to moving away from oil.
And yes, Earth's climate has always been changing naturally. But we humans are adding on top of that natural changes. We can't do anything about natural processes, but we can change the human impact. We could be the first species that caused our own extinction. While that will be in the future, it is a possibility. And Greta is absolutely right about that!!! Life depends on certain environmental conditions to exist and it either has to adapt or go extinct. And that's simple biology, chemistry, history.
In Earth's past, CO2 levels may of been higher than now, but species also adapted or evolve in those conditions.

We have released 10's of millions of years of worth of CO2 in the matter of 200 years.
It seems like if you start doing research and asking questions and it comes to reducing our use of oil. Can't be done, got to protect the oil industry no matter what.
In the end the Earth it self doesn't care what happens, it has seen it all. It's just weather Homo Sapiens will continue to exist or just become just another footnote in history. And while that may of come naturally eventually, we are speeding up that date to extinction.
