How Mars lost its atmosphere and became a cold, dry world

A NASA spacecraft orbiting Mars spies solar storms blowing Martian atmosphere away.

'Although the planet’s atmosphere is presently losing about 100 grams per second—the equivalent of a McDonald’s Quarter Pounder—scientists say Mars lost the bulk of its once thick atmosphere billions of years ago, a relatively short time after our solar system formed. The findings were published in multiple articles Thursday in Science and Geophysical Research Letters.....after the old Martian atmosphere left, scientists now understand it was carried away by the solar wind, gone forever. Additionally, absent a strong magnetic field, it would be difficult to consolidate gains made by thickening the Martian atmosphere by other means'.

So Cohagen's will NOT be terraforming an atmosphere, dammit

Fusion reactor into the core to heat up the iron?

My gosh, the old brain is cooking with gas/coal/something tonight


Bring out the three boob space junkies..

In 50 years time this will be earths fate if we don't get a handle on global warming.Wake up people we are DOOMED !!

Thats about right and we are heading for the perfect storm

What effect has Global Warmimg on the earth's magnetic field?

Well, the earth gets warmer and the poles melt, carrying all the magnetism away into the sea. That makes the fish magnetic, so they jam up the cooling intakes of nuclear power stations, which all explode. That destroys the ozone layer which lets more UV light in so everything gets skin cancer, which is made worse by the acid rain. As the earth's magnetic field tilts it attracts lost of asteroids which all crash into the earth and make big tsunamis which kill millions of people, if they're not already dead from eating GM food.

I think that's everything...

yep, seems about right

I'll save this concise info for the next time I need its content

(Already have grandson querying teacher's assertions on the topic without even trying to convince him. He has the ability to question what they tell him

Could it be because so much of it is gobbledygook?)

Very unlikely,

But he's ot what he wants. Give the people aeyuh!

I don't think JagerT's comment was referring to a magnetic field I took it as if we don't look after our own planet we are all fked and we won't be hopping off to Mars anytime soon to save our species

[Eric Mc]

Possibly.

My prediction could be - "The Earth Dies Waiting" i.e. whilst we were hanging around waiting to solve all our problems, we accidentally became extinct.

I think we should just get on with it and stop faffing around.

[Simpo Two]

I think it will be harder to kill all 7 billion humans than the 'OMG we're all doomed' people think. Even if a global catastrophe wipes out 99.9% of all humans, that still leaves 7 million. H. sapiens got to where he is for a reason.

Not possibly Eric, defiantly, the Earth doesn't give a care about us, unless we care for our environment we will be fked. Thinking we can just planet hop to solve our issues I would suggest is stilted thinking particularly when you see some comments that view other worlds/planets as a resource for humans to harvest, its what is causing issues on our plant so what gives us the right to despoil other worlds? As Chris Lovelock said 'enjoy the party while you can'

There is a Swedish word 'Lagom' and whilst there is no direct translation in essence it means balance in everything, if we got that right as humans it would be a better world.

[Eric Mc]

It would - but human nature doesn't change. Hanging around waiting for the impossible is wasting time.

[Simpo Two]

Visiting/colonising/terraforming other planets shouldn't be seen as an escape from an Earth that can no longer support life (though eventually it will be). Such things should undertaken as a continuation of exploration; colonising another planet is no different from colonising a country, just harder.

As for the Earth's problems, rather than paying 5p for a carrier bag, we need to control population.

It seems someone has taught your grandkid to think, that's not acceptable in modern society.

If we carry on the way we are we are all doomed, 100% Extinct what makes you think there would be any survivors?

The probability of an asteroid impact, at some point, is 1.0; if we don't get off this rock it doesn't matter how much of a garden of eden we make it, it's toast, and so are we.

Your right, there can be multiple demises of Man and the planet still doesn't mean we shouldn't look after it until then
