Mars is increasingly in the viewfinder of planetary scientists, as NASA has made it a goal to send a manned mission to the red planet, sending rovers to its surface and developing technology to prepare for human exploration. The increased focus on Mars has led to some intriguing discoveries - most recently, that life might have existed on the planet before climate change ended it. That's the suggestion of a new study; read on to find out more.
Researchers from the University of Arizona aren't positive there was once life on Mars (in a news release, they call it a "big if"), but they've determined that conditions on the young planet could have supported it. In their study, published in the journal Nature Astronomy, the researchers note that today Mars is dry and freezing cold, seemingly uninhabitable. But four billion years ago, the planet had an atmosphere that was conducive to life - rich in carbon dioxide and hydrogen, which would have allowed water to flow and microbes to flourish.
"Our study shows that underground, early Mars would very likely have been habitable to methanogenic microbes," said Regis Ferrière, a University of Arizona professor and senior author of the paper. These kinds of microbes live by converting chemical energy from their environment and releasing methane as waste. Some of the same kinds of microbes exist in extreme habitats on Earth, such as hydrothermal vents along fissures in the ocean floor.
"The research team tested a hypothetical scenario of an emerging Martian ecosystem by using models of Mars' crust, atmosphere and climate, coupled with an ecological model of a community of Earthlike microbes metabolizing carbon dioxide and hydrogen," the university said in a news release. They determined that about 4 billion years ago, Mars' atmosphere contained a high amount of hydrogen...

What crap.
Mars has less mass.. it’s core slowed down, losing its magnetosphere (or at least a consistent shielding ability of if).
Mars is dead because it’s atmosphere was blown away by solar winds after it lost its magnetosphere.
Climate change?!? Please
Govt paid scientists can blow it out their asses.
What a crock.

I agree. What a steaming pile.
the signs of life are everywhere... the, uh, the fossil, er, um, record, shows significant, um, look, climate change.
Martian farting cows. I wished I could have seen that.

It was the "disgruntled martians" who were responsible.
Hang on…
…it MAY have had life. (They don’t even know..)
But “climate change” ended life there. (Absotively Posilutely!!!)
These people are idiots with an agenda.
The term “climate change” is so darn elastic. By the magic of equivocation it means we can link the result of Mars like climate with the actions of humans on Earth that don’t really have much impact on climate outside of flawed computer models and intentionally distorted data.

We need a detailed explanation of this phenomenon from non other that that esteemed professor of all knowledge Professor Corwin.
Today’s scientists come up with their best theories when they’re drunk, stoned and their grant money is running out.
Is there nothing that human caused global warming can’t do?
My bad....ha ha ha
What an angry little person.

Not familiar with Professor Corwin. Had to do a web search to see who you meant...and found wikipedia page for Edward Samuel Corwin. He died about a year before I was born it seems.
What do you think the esteemed professor would have said about the climate change stuff?
😜🤣
Great idea 💡!!!
I blame Marvin the Martian.
