Why our galaxy probably isn't full of alien civilizations killed off by climate change
NBC "News" ^ | January 9, 2019 | By Seth Shostak (D-NBC)

If extraterrestrials are out there, odds are they're too clever to have been blindsided by global warming run amok.

Could it be that climate change is a universal menace?

A recent article in Forbes addresses the idea that the galaxy might be strewn with extinct alien civilizations, burned to a crisp by ferocious planetary warming. The idea is certainly intriguing, and has obvious relevance as a cautionary tale for us. But could it be true?

The article doesn’t say these hypothetical societies died out thanks to an alien fondness for SUVs. Instead, the aliens are hypothesized to be the victims of a natural process - the aging of their home star - coupled with the bad luck of having no planet similar to Venus in their solar system.

The time scale for the sun’s brightening is on the order of a billion years, and for most stars even longer. And that suggests that this particular problem may not be high on any aliens’ list of worries. Stephen Kane, the University of California astronomer upon whose work the Forbes article is based, says we can expect some serious temperature oscillations much sooner.

Undoubtedly, there are many ways that alien societies might tank. But this one seems improbable. If our cosmic confreres are advanced enough to be our intellectual peers (or better), they’re clever enough to see the dangers of a star growing old, and do something about it.

The Privileged Planet
https://www.youtube.com/watch?v=QmIc42oRjm8&t=926s

THE PRIVILEGED PLANET, utilizing stunning computer animation, interviews with leading scientists, and spectacular images of Earth and the cosmos, explores a startling connection between our capacity to survive and our ability to observe and understand the universe. Is this correlation merely a coincidence? Or does it point to a deeper truth about purpose and intelligent design within the cosmos? THE PRIVILEGED PLANET is based on the book with the same title by Jay Richards and Guillermo Gonzalez. Production began in October 2002 and was completed in June 2004. The documentary presents the Richards/Gonzalez hypothesis that the Earth was designed to both sustain complex life and enable scientific discovery.

Yup. Spot on analysis. Four billion, maybe four and a half but our star will use up it’s hydrogen and then burn through just every element on the Periodic table as gravity pushes in and our star either goes super nova or collapses in to a black hole. That is unless sometime way before that a huge chunk of iron or a comet crashes into us. Then it could be game over.

Yeah, right? Can get here from the next star system or galaxy but about as soon as they get here right away BAM! The old space ship breaks down. And some how all the rubes,the Earthlings that it is, seem to know when they're witnessing the saucer men outside the spaceship, they somehow all seem to know, or certainly all seem to agree that the spaceship was having engine trouble. Amazing ain't it?

An UFO landed in Washington DC. They went to the capital and saw Chuck Schumer, Liz Warren, Maxine Waters, Hank Johnson and Shelia Jackon-Lee. They decided to leave, because they didn't find any intelligent life. 😀

Instead, then went extinct when their respective single party state advocates managed to enforce their gender dysphoria model and the populations died out. Thanks Oldeconomybuyer.

By the time they reach us, the manufacturer’s warranty is expired.

Given a billion years, we (or some alien civilization) would be pretty pathetic to not be able to "parasol" (shade) the Earth well enough to get at least another billion years out of the deal. In 2 billion years, we ought to be able to figure out further strategies, or, just leave.

Not to mention that around that time our galaxy, the Milky Way is supposed to be just about colliding with the Andromeda galaxy.

That will provide a quite a selection of new (well, used but still newer) stars to check out.

Love that new star smell.
