Climate change may prevent contact with alien civilisations

Oddball headline, but the article is quite interesting: something I didn't know, stars tend to increase their output with age. Meaning that a planet in the habitable zone of a solar system may not be in a few million years.
In our own case, the only reason Earth has remained habitable is that more land has slowly been created by volcanic processes, and life has of course sequestered massive amounts of carbon, both of which neutralized the effect of increasing output from the Sun. Which makes the current situation with CO2 even more pressing, IMO.

We would probably just shoot any aliens that showed up, or detain them. djean111 Jun 2014 #4

It means that even if pretty much everything goes right, we've got far less time to get our act together and free ourselves from the limit of a single planet in far less time than would otherwise be the case. Or learn how to move planets...

Why would they bother to show up? Obviously we are not advanced enough to work with. Not while republicans still roam wild anyway.

to tell us to stop?

From that highly intellectual site The Discussionist:

The question liberals are afraid to answer

Question: If climate change, or global warming, or whatever you want to call it, is real and will destroy humanity, then WHY hasn't someone come from the future to stop it before it happens?

Answer: If climate change would destroy our civilization, it would have never happened in the first place, because someone would've come back in time to prevent it. "Scientists" say we're too late to stop it, obviously if climate change turned out to be a big deal, someone would've stopped it already.

Conclusion: Climate change is either A. Not real or B. Nothing to be conserned about.

Sadly, the poster has not yet given us any more pearls of wisdom.

More to the point of your post (rather than the headline) is that scientists once thought we were near the middle of the zone of habitability (distance from the Sun). Now, it appears, we're within the innermost 1-3% of that zone, which does not bode well for the medium- and long-term.
