It would be a time that humanity would not be able to survive on Earth without the technology to survive an unstable world hostile to life, though given that the natural environmental changes that occur all the time anyway (the reason there are whale bones found in the Sahara is because it cycles between lush jungles and water to sandy desert, over and over again, and human ruins from before recorded history--possibly not human ancestors--have been uncovered there which also suggested it was along a river as many ancient villages were), humanity is unlikely to survive see such an event anyway (unless we're interstellar by that point).

This is regardless of any man-made environmental change, the Earth changes on its own, sometimes with no polar ice caps, other times a frozen ball of ice, all before humanity, and it will continue to change like that. I've been told that people who focus their study on the geophysics of Earth actually suffer from existential dread more than those who focus on astronomy.

Our planet also has records (that is fossils, geological signs, etc) of solar storms that make the Carrington Event (which caused telegraph lines to burst into flames) look like a gentle rain in comparison, and even another Carrington Event (one that missed the Earth by 2 days in 2012) which would bring our technological civilization to its knees (though I've heard a brilliant idea for preventing that, but humans are too short sighted to do that), and that will happen a great many times before we're in the actual extinction zone.

But imagine the night sky there filled with stars like miniature suns! (At least so bright that one could read in starlight.) It must inspire awe if humans were able to see it. (Others have said that things we don't see might then be visible, and that other celestial events we know nothing about may have been visible on Earth millions of years ago that we know nothing about, and may never know about it).
