Claim: ‘Why Can’t We Find Aliens? Climate Change Killed Them’

Fresh on the heels of the recent news surrounding the increasingly dire climate forecast for our planet, comes a possible warning from the cosmos: climate change in extraterrestrial environments is inevitable and, should life on hypothetically habitable worlds not act as a stabilizer for their environments, it serves as a “sell-by” date for all burgeoning lifeforms.

In new research published in the journal Astrobiology, astronomers of The Australian National University (ANU) pondered this scenario and realized that young habitable planets can become unstable very quickly. What once was a life-giving oasis becomes a hellish hothouse or frozen wasteland very quickly.

“The universe is probably filled with habitable planets, so many scientists think it should be teeming with aliens,” said Aditya Chopra, lead author of the paper. “Early life is fragile, so we believe it rarely evolves quickly enough to survive.”

“Most early planetary environments are unstable. To produce a habitable planet, life forms need to regulate greenhouse gases such as water and carbon dioxide to keep surface temperatures stable,” he said.

Unlike Earth, most worlds will likely not find this balance, ultimately succumbing to being cooked by a runaway greenhouse effect (like Venus) or frozen by a thinning atmosphere (like Mars). Life will often not be fortunate enough to win the race against environmental fluctuations to become a stabilizing factor.

Earth, which already has the stunning fortune to exist at just the right spot around a stable star, spawned life and that life had a role to play in stabilizing its atmosphere as it evolved over that last 4 billion years.

“Life on Earth probably played a leading role in stabilizing the planet’s climate,” said co-investigator Charley Lineweaver, also from ANU.

And this could be why we’re not finding a galaxy filled with alien life — just because there’s a habitable world out there, it doesn’t mean it’s suitable for life for long. It’s yet another hurdle against life from gaining a foothold.

“The mystery of why we haven’t yet found signs of aliens may have less to do with the likelihood of the origin of life or intelligence and have more to do with the rarity of the rapid emergence of biological regulation of feedback cycles on planetary surfaces,” said Chopra.

For now, this is all speculation, but what’s clear from observations of our own planet, is that the mother of all existential self-inflicted bottlenecks is on the horizon and, unless we find a way of reversing the damage we’ve caused to our environment, it seems we’ll quickly become just another lifeform that didn’t make the grade.

    • If global warming causes terrorism, it causes mass migration and mass illegal immigration. The left just hasn’t thought up a scenario for it yet. They’ll have to motivate the NOAA/NASA to produce fraudulent, laughable data from countries that export their people to the US.

      • This article is ridiculous. Claimant change happens every minute of every day of every year for all time. There is a reason why our planet had ice ages, had periods of time hotter than Haiti in July and went back and forth 100’s or 1,000’of times and it has NOTHING to do with Humans and our ability to make power, which has only been around for 150 years.
        .
        If anything Humans need to continue developing our machines and our ability to make power in order to survive what earth, sun and the cosmos throws at us, if you want to believe the findings of this article.
        .
        To think that if humans did nothing the planet would be stable for eternity is perhaps the most ignorant thing someone could believe.

        • Do you even know how to read? Cus if you do, your reading comprehension sucks balls.

          All the author states is exactly what you said… environments of ALL planets changes rapidly… which is true. And you turn that into a political arguement. Wtf is wrong with you???

          • hey bucko, the author also said that we need to do something to change the environment, i.e be more green or some stupid statement.
            .
            You attack me and many others with the same BS (at least get some originality in your angry tirades) and offered nothing, typical troll. I stand by my comment, maybe when you can think for yourself, you will understand.

        • If you lived in a desert….and it got hotter.. what would you do?

          Im not defending them, and i dont want em in my country…but changes in climate will absolutely increase migration of people without means. Hard to blame them.

          I wonder, do you blame birds that migrate south when it gets cold??

    • Evolution. Grey aliens evolved into Democrats, Lizard aliens into Republicans. It was fast too, since Jesus created the entire universe 6398 years and 29 days ago, Give or take a day. And that is just as scientific as DIscovery, apparently 😉

  1. “Life on Earth probably played a leading role in stabilizing the planet’s climate,” Total bollocks. The Earth doesn’t care about the lifeforms on it. It does its thing. It’s up to the lifeforms to adapt or they become extinct. That’s why 99.9% of all species that existed on the Earth at one time are now extinct.

  2. These people are freaking insane! Man made global warming killed off the Aliens huh? What kind of weed are you people smoking? If I just pay the Rothschild family 50% of my income everything will be saved huh. We need to hang these globalists ilk. A bunch of communist Jews want to enslave the planet. I guess they realized that their talmund is a dudd and the only way for them to each get their 2800 slaves is through climate change. Synagogues of Satan.

    • there also seems to be some mis-labeling:

      Hundreds of cases of ufo/abductees calling on Jesus to end their abuse have been documented.

      yt:Unholy Communion: The Fourth Kind Unveiled – Joseph Jordan and Guy Malone

      “Human beings are under the control of a strange force that bends them in absurd ways, forcing them to play a role in a bizarre game of deception.”

      –Dr. Jacques Vallee

      “The UFOnauts and the demons of past days are probably identical.”

      –Dr. Pierre Guerin

      “The UFO phenomenon simply does not behave like extraterrestrial visitors. It actually molds itself in order to fit a given culture.”

      –John Ankenberg

      “One theory that can no longer be taken seriously is that UFOs are interstellar spaceships.”

      –Sir Arthur C. Clarke

      “The evidence suggests that this is a program.”

      –Prof. David Jacobs, Temple Univ.

      “Can we exclude the possibility of an extraterrestrial evangelism?”

      –”Carl Sagan, The Andreason Affair,” ”Raymond Fowler

  3. Pronouncements and statements about life on other planets — and not one single piece of evidence currently exists that life exists even outside earth in this solar system. What we know about possible planets in other star systems is slim and what we know about their geology and climate approaches nil. So, these scientists are writing either science fiction or scientific philosophy, and not really science. Sheesh.

  4. The one thing that amazes me is that Planetary Scientists keep on Making Marvelous Outrageous claims based on their Flawed Theories of the Past….and then come up with some Mathematical Formula to prove their point !
    I call them Math-a-Magicians !

  5. Aliens are demons taking advantage of gullible sinners. That’s all they are. The climate always changes. Always will. Global warming is a pseudo crisis caused by politicized pseudo scientists, most employed by government agencies, desperate for funding, opening their mouths too often and preaching the hot-air of disaster if we don’t agree to higher taxes and a return to a pre-industrial society & culture. Same with evolution and heliocentricism.

  6. This is entirely insane speculation, start to finish. The only thing that’s predictable is its advocacy of taking measures to prevent climate change, with the implied necessity of big government, reduced living standards and high taxes for most, (but with the elite few who oversee the work living lavish lifestyles). Not science, not to be taken seriously.

  7. 12,000 years ago, North America was under hundreds of feet of ice and sea levels were 350 lower than they are today. Without any help from humans it warmed up a whole bunch which allowed humans to thrive. What actually causes the Earth to get warmer and colder? The distance from the sun as it’s orbit changes.

    Yes, it will get very cold again and there is nothing humans can do about it. It is pretty silly to believe humans can alter climate to any significant degree… Even if you believe the alarmists, they are talking about a sea rise of 4 to 12 feet at most and temperature increases of less than 10 degrees… that’s nothing. We will be happy to be starting from there when we go into the next ice age.

    • Very interesting that you should say that 12kya North America was under ice. 12kya, there was the extermination of the Clovis Point people (very high stone age tech arrowheads), the extermination of the megafauna of the Americas, a huge jumble of megafauna bones it Alaska, wildfires across the continent, and a bolt of suborbital ballistic glacier that came down in Siberia and flash-froze mammoths. Oh, and a layer of iridium laid down across the continent (iridium is an asteroid indicator). So it’s more likely that an asteroid did that particular bit of damage. Possibly it hit a glacier-covered mountain in Alaska, vaporized the glacier (sending it ballistic to Siberia), and then vaporized in the face of a mountain, causing a fireball to consume most of the northern continent.

  8. Wrote about this already in my books. The theory is that a dominant life form inevitably evolves to a level where it can overcome natural governors that otherwise control its population. This apex life form eventually must do one of two things: 1) Evolve its *spirit* to no longer need natural governors–and govern itself; that is to say, it no longer mindlessly and selfishly breeds but instead lives intentionally and voluntarily occupies its ecological niche and niche function, or 2) Destroy the entire planet.

    This is a “group pass/fail test.” It is not merely the apex species, or even the individual offenders in that species that dies, but instead all of the members of that species plus the entire planet.

    Put yet another way, there is a natural barrier to cross before the “Next Level” can be accessed. A planet seems to need to prove itself worthy before attaining the technologies and knowledge to go forth into the cosmos–for the planet to bear seeds. Like flowers, not all planets succeed in bearing seeds. Only the healthy ones make it.

  9. they somehow created technology to come back to earth to visit, and then they died because of normal fluctuations in the earth’s atmosphere…one they were already aware of? is there an editor at climatedepot?

  10. Wrong term and its backwards the ones who are spraying are Nazi’s Communists and Humanists I like to call them CommuNazis! They are tools of the Devil all demonic in nature all looking to cull the population using things like Climate change which is crazy. Of course there is climate change we have four seasons to contend with. Although I do see them sky writing swastikas in the air once in a while over where the Italians hang out in the woods. See the Georgia Guide Stones. I guess the E.T.’s are Italian…LOL!

  11. There are several major drivers of climate, most outside of earth. Weather is driven by internal water temperatures and atmospheric events. But what really causes the internal changes? Try this: If human activity completely ceased for a 24 hour period, no heating, no emissions, no nothing, the earth would wake up tomorrow as though nothing happened. However, if the sun ceases activity for 24 hours, the earth becomes an ice cube and all life is dead the next day. Also if our spiral arms go through a dusty area of space as the galaxy rotates on it’s 500,000 year rotation through space and encounters a significantly higher region of dust, we could have a very quick ice age and massive death on earth. It were to rotate into a less dusty area, we could be bombarded by massive radioactive forces such as gamma rays that could kill most of life on earth. A supernova in our neighborhood (within 130 light years) would burn us to a cinder. The fact is, when you look at macro causes of climate change and compare it to human influence, the AGW is very minuscule. We have lots of geographical and atmospheric and biological hx to measure these macro events that have happened with some regularity in the past. At best, right now, we’ve got about 50,000 years of relatively peaceful macro space activity and then we’d better be gone. Internally, a massive volcanic blast which fills the atmosphere with dust is probably our greatest risk, but that is usually a short term event even if devastating. If through AGW (if true), ice melts and the oceans raise, it will cause some relocation but won’t be the end. A greater threat to man is political control over food and energy sources and deliberate self destruction from nuclear or biological warfare or mass starvation cause by political policies that leads to world wide violence and anarchy. Besides, the story is a lie, aliens are alive and well and I have two of them living in my house. They are called Chihuahuas and there is no record where they come from, they look unearthly with huge alien like eyes and they use their eyes to project mind control powers into human brains to make humans their slaves.

  12. Well these guys (aliens) arn’t in the bible except for the description of giants which mated with the women. I thought just large men from far lands (not planets)) They didn’t have the little space men in the Roswell incident. They did have camels, oxen, horses, and people trying to raise families.
    People who do not respect history are doomed to a life of mindless drivel.
    The Bible covered approximately 6K years of humanity and God’s handiwork. As accurate as we have.

  13. I wonder if these “scientists” realize that earth spent more time with a poisonous atmosphere that was changed by algae to our current atmosphere. It was only after a few billion years that we got a O2 atmosphere.

  14. This is what happens to science when it is politicized. If you even question global warming killed the aliens you are a science denying flat earther. Also, chromosomes don’t determine sex – that’s a subjective thing that may change on a daily basis, you transhomophobe.

  15. Just when you thought these people couldn’t be any more mental, they up and surprise you again. This wild claim can’t be proven, It’s conjecture. They’re just trying to make their climate change fantasies more credible. It could be that the distance from the sun has an effect on planet temperature, but I’m no “expert”.

  16. People that claim that the ETs have all died or have never existed I only have THIS thing to say.

    Such people simply do not fathom the true size of the Universe. As a consequent, these same people can not fathom it contents either. As long as time is arrow and light is what it is we will not be able to communicate with anything outside our light horizon. (Distance our first radio transmissions have traveled) Anybody outside of this light horizon would see the Earth pre-industrial, go out further, and they see cavemen, even further, and we cease to exist. And yet, in that exact same moment that THEY observe US crawling out of the swamp, WE are in reality, are walking on the moon.

    Go out far enough and there is no Earth to observe. Yet clearly Earthlings exist. In that exact moment. Just as our information is outdated in direct proportion to the distance of the object being observed, so it is equally true to an outside observer. People out on Sirius see us as we were 10 years ago and yet other than the Sun, it is the brightest star in the sky Call it a law, constant, whatever. Light is to blame. Light keeps everybody out of date.

    So what we are left with is Schrodinger’s Universe. Life is observed,and life is trying to observe itself.

  17. The invasion of the body snatchers is well under way. Everywhere you turn there’s another “progressive”, foaming at the mouth and screeching incomprehensible hatred towards human life forms. These are truly frightening times.

  18. NATURAL climate change happens on all planets and there is nothing (or very little) any intelligent society can do about it. However, if a society had a nuclear war, that would be the primary cause of their demise. In that case, they were responsible for “climate change.”

    Another hysterical group says extraterrestrials nuked themselves to extinction before acquiring the technology to travel to habitable planets in other solar systems. Some claim that this is why we are not receiving radio transmissions from other societies.

    What probably happened to most intelligent societies has much more to do with nature than with their activities. Meteors could have destroyed life on some planets. Dying stars could have expanded to the point of destroying life on many habitable planets just as our sun will a few billion years from now. Gamma rays and other bizarre incidents can fry planets in our unstable universe, especially on planets closer to the center of galaxies.

  19. If humanity “has to be a Stabilizer for the environment” I wonder what this planet did before We came along?
    Oh that’s right! It was just Fine!!!!
    Pristine In fact.

    This stuff they think up is right outta the freakin Twilight Zone.
    Like Really?
    They must be High off their Asses on Peyote buttons, if they expect Us to believe this dribble!

  20. “Probably”, maybe, woulda, shoulda, coulda…. Yep, it is all speculation, but written as if we’re, (the human population) the problem.

    This is such a planted hit piece for those still believing in Global Warming. We’ll make the grade all right, and we will adapt as we always have. THAT IS WHY WE ARE STILL HERE !!!

  21. Not sure if this is an Onion piece or if it’s a serious attempt at journalism.
    Either way, it’s funny. Like the scientist who said humans will evolve to develop webbed feet and hands to cope with the rising oceans from climate warming. And he was serious.

  22. Way back in history, while the middle class aliens were driving trucks and SUVs, and the alien cows were passing carbon gas, the rich and famous alien elites similar to our earth’s present day Leonardo DeCrapalo started flying around the planet in their carbon burning private jets to meet with other world alien leaders and alien popes to tell the common alien folk to stop burning fuels and letting their alien livestock to stop passing gas or the planet would burn up. Well, these alien leaders released so much carbon with their global meetings, and released so much bullcrap and hot air from their own mouths, that ironically, they themselves burned up the planet. Is history once again repeating itself? Earthlings, does this not make as much sense?

  23. If the gas producing life is the feedback loop responsible for a sustained equilibrium, who’s to say the life that now produces the same gases is bad for the planet? Who is to say what is naturally occurring isn’t natural?
