Martian life might have thrived in the planet's early days. A new study found climate change may have driven it to extinction.

on Earth. And according to a new study, Mars may offer an example of the damage that can occur to life itself because of the greenhouse gas effect.

How did they come to such a discovery? University of Arizona researchers created hypothetical scenarios of Martian ecosystems using models of Mars' crust, atmosphere and climate, as well as an ecological model of methane-producing microbes. Scientists found that Mars' early days would have been the right conditions for life to prosper, but a global cooling event likely would have taken place because of some life forms' consumption process, making the planet's surface uninhabitable. But that thriving population could not last, scientists found, because of all the methane the microbes produced.

The study does note that its modeling likely underestimates the global cooling effect, as it doesn't consider increasing albedo, or the ability of surfaces to reflect sunlight. The more ice that is present, for example, the more of the sun's rays could be reflected away from Mars' surface, keeping temperatures cooler. That process is what also contributes to Earth's warming as sea ice melts, allowing more light to be absorbed in the deep and dark oceans.

Curious; does Mars planet still have oil in the ground🧐

Slow news day I see.

Funny how studies can show life on other planets,but many would not believe that there were fallen angels on earth in the first earth age! 🤔Can it be that man is finding out there really is a GOD !

Probably the oil in the ground is already depleted🤔

Republicans should like this, the whole planet will go Red.

Think we’re from those planets, if you really think (c) Donald trump

So mars had life and climate change caused their extinction do 97% of scientists agree with these statements

Yes there was life there before. It is written in the history of earth before Stone Age.

So we’re humans there and caused it? Hmm, maybe humans aren’t the cause of climate change and climate just changes naturally as it has done for millions/billion of years

Of course..

Youre saying this. But do we have proof of life. I havent heard about that. I feel like someones setting up an argument that science can be ridiculous. And thats not the message we want to send. Like maybe through studying Mars and climatology you could make suppositions how went

Hahhhaaaaaas

Musk is a pretty smart guy and he says we could colonize Mars in the future.

Come on, man!

LMFAO

I’m just glad our scientist know exactly what kind of climate a Martian can live in and what would be detrimental to their existence. Being that none of us have ever met or lived with a Martian before

Proof please ya freaking liars .

They didn’t spend enough money

Climate change is a planet thing, not so much a human thing after all. Climates change because planets are living organisms in their own right. They are not as static as we humans want them to be. Tough nouggies.

All species come to an end. Unfortunately, humans have been around for a short period of time but will leave in the not too distant future after making the Earth uninhabitable for so many other species.

Scientists can’t get a five day forecast right here on earth but we know climate change killed mars. JUST STOP

O Lord. Seriously.

Maybe Mars is just Earth 20 years in the future. OR at least what we will become if we don't start all driving teslas

Shit... Did aliens impact their climate too or did the climate just change?

Bullahit!! More DNC and media scams

Elon Musk can fix it, he should go live there now. 😏

anthropogenic?

Very important lessons to be learned from the ancient past. All planets are living things and if not protected all life is fragile.

yeh sure 👍

The same thing is happening here on earth. Humans are the 'bacteria', making the atmosphere uninhabitable. At least the bacteria had a lot of excuses?🤷‍♂️

Was it man-(ha)-made?

That’s right!!!! We need to blame all our planet 🌏 climate issues to the clandestine residents that live in Roswell New Mexico!

Oh give it a rest.
