@SW-User Good luck with that. Given there is no other habitable planet in our solar system, the nearest rocky exoplanet may be around Proxima Centauri, a red dwarf star approximately 12 light years away - that is 60,880,000,000,000 miles. But chances for a habitable environment around a red dwarf star are roughly the square root of zero.
You have been reading too may alarmist prognostications. The thing you really should be worried about is the rather sudden return of glacial conditions. Remember, we are moving towards the end of a typical 14-18,000 year interglacial of the quaternary glaciation era. The earth - and humans - will survive. Our planet has remarkable self-correcting mechanisms which the infinitesimally small human presence has no effect on at all. But stock up on fur coats. The big chill is just around the corner in geological time.
