Putting Descartes before the horse?

Ancient microbial life on Mars could have destroyed the planet’s atmosphere through climate change, which ultimately led to its extinction, new research has suggested.
The new theory comes from a climate modeling study that simulated hydrogen-consuming, methane-producing microbes living on Mars roughly 3.7 billion years ago. At the time, atmospheric conditions were similar to those that existed on ancient Earth during the same period. But instead of creating an environment that would help them thrive and evolve, as happened on Earth, Martian microbes may have doomed themselves just as they were getting started, according to the study published Oct. 10 in the journal Nature Astronomy.
The model suggests that the reason life thrived on Earth and was doomed on Mars is because of the gas compositions of the two planets, and their relative distances from the sun. Being farther away from our star than Earth, Mars was more reliant on a potent fog of heat-trapping greenhouse gases, such as carbon dioxide and hydrogen, to maintain hospitable temperatures for life. So as ancient Martian microbes ate hydrogen (a potent greenhouse gas) and produced methane (a significant greenhouse gas on Earth but less potent than hydrogen) they slowly ate into their planet’s heat-trapping blanket, eventually making Mars so cold that it could no longer evolve complex life.
The scientists believe their findings suggest that life may not be innately self-sustaining in every conducive environment it pops up in, and that it can easily wipe itself out by accidentally destroying the foundations for its own existence.

It’s a little more complicated than that. Mars could hold nitrogen. It just didn’t get a significant amount. It can hold oxygen, but the oxygen hooked up with iron, forming a red compound we refer to on Earth as ‘rust’. Hence, Mars is known as the Red Planet.
What Mars can’t hold is hydrogen. It should lose half or more of atmospheric oxygen in roughly 40 million years. If one assumes 4.5 billion years, that’s 112 times to lose half the hydrogen. Thus any hydrogen remaining is buried in ice or subsurface water.
H2O gets broken up by ultraviolet light quickly without lots of ozone in the atmosphere. Gravity on Earth keeps the hydrogen around long enough to recombine with oxygen. Pre-life Earth had no free oxygen. There is no convincing evidence that Mars ever had or has life to date (2022).
Flipside, human engineering could easily bring life to Mars, by adding atmosphere deep enough to hold heat. 1% of the atmosphere of Venus, minus excess sulfur, would work.
Separating the Martian rust into iron and oxygen using standard techniques would help, and then hauling ammonia from any available source to make amino acids/proteins. Glass or clear plastic will block UV. But these changes require human or machine intervention, and won’t happen spontaneously. It takes a Creator to terrform a planet.
Actually, those who understand models well also understand that the output of a model is 100% dependent on the input to the model. Freeman Dyson, British scientist, understood this when he pointed out that all climate models are rubbish, as computationally correct weather models require scale down to well under one mile, which computationally is impossible to do. Our computers are not, and cannot be made fast enough for turbulent, chaotic systems in four dimensions.
Another way to explain this is to note the smallest possible computer that has the computational power to predict weather (and then only for up to 10 days maximum) are - either Earth itself, or an exact replica or Earth itself, also revolving around this Sun.
The climate ‘models’ all use fudge factors. Reason: when they didn’t use fudge factors, the Earth’s temperature would increase by about one degree per day. The fudge factors allow the model to have an artificially induced stability that calculations do not permit.
In other words, the basic models are flat-out wrong, and the creators of the models know this. Further, you or I couldn’t make a model significantly better that used computation, as we can’t model climate due to the small-scale effects.

In other words, garbage in, garbage out?
Using/Imputing faulty or manipulated data/information will invariably result in the output of faulty data based upon that faulty or manipulated data/information?
Putting Descartes before the horse?
Horseshit.
Beware. Common sense has been replaced by Google.
Yes. Humans have had thousands of years on earth to choose to live underground, and rejected it. They are not about to reverse course just to become “colonists” on some G-d forsaken other planet.
What nonsense...
Mars cooled, its core slowed down, its magnetosphere broke down, and its atmosphere was washed away by the solar winds.
What absolutely nonsense is this garbage... Mars is not “dead” because of any sort of domestic induced climate change.
The only reason WE are here at all is because for millions upon millions of years, microbes generated Oxygen... to a point where there earths atmosphere is now 21% of the stuff... O2 is actually poisonous to may things... then something also happened, an organism evolved that could process O2 and generate energy, this allowed the evolution of higher life forms...because using O2 for energy generates far more energy than other gases.
Had neither of these two things occurred we would not be here.
No kidding, huh? I mean I tend to believe there must be life on other planets and likely some of many forms could be much more advanced than us but my belief is based on the number of planets out there and math. The chances would be high.
That said, these people are really stretching it - actually there's nothing there for them to actually stretch. Basically they are telling a big lie and jumping the shark. The only life they suspect may have existed on Mars would be microscopic and how could that cause global warming / climate change?

Exactly!
” At the time, atmospheric conditions were similar to those that existed on ancient Earth during the same period”
HaHa - Wrong orbital path pal.
Thar be a significant difference in distance to the sun?
Venus: Average: 108 million km / 67 million miles (0.72 AU)
Earth: Average: 150 million km / 93 million miles (1.00 AU)
Mars: Average: 228 million km/ 142 million miles (1.52 AU)
Hydrogen would have escaped the planet even faster than methane.🙄
I recommend preparation H.😏
Lol!
