Evidence of Liquid Water on Mars!!!

[bluefrog]

HOLY SHIT!

WTF?!?!?!?!?!

 

[BLAZER PROPHET]

Looks like water to me.

Someone grab my surfboard.

 

[bluefrog]

Time to colonize Mars. We could stock the water with salmon and bass!

 

[Eastoff]

it is not evidence of liquid water, it is evidence that liquid water probably exists. It's just the most likely explanation.

 

[bluefrog]

it is not evidence of liquid water, it is evidence that liquid water probably exists.

What's the difference between evidence of something and evidence that something probably exists?

YEAH!!

Can I fit my boat on the next shuttle. Oh, wait, there are no more space shuttles. Damn!

It's called a marriage.

HEYYOOOOO!

One is fact, one is probably true.

There's global warming on mars.

 

[Eastoff]

There's global warming on mars.

don't be ridiculous, there are no humans on mars to cause it.

Exactly. But most of the planets are warming.

 

[Eastoff]

Can I see the data or source?

Google "mars warming" and you'll find numerous reports. If you look just a little bit, you'll find one about a 2nd red spot on Jupiter they believe is caused by warming.

The only reputable source I found was national geographic and they point out the perturbations in the revolution in the sun cause the change in the climate. (get too close the CO2 caps melt, get too far and they build up) Because mars doesn't have a moon to balance it, the planet wobbles more frequently.

It's pretty obvious that the earth's albedo has a HUGE effect on warming. As the glaciers from the ice age 10,000 years ago receded, there was less and less white stuff (snow, ice) to reflect solar radiation back into space, and what the glaciers uncovered was dark enough to absorb heat from the sun.

You can't assume that the temperature increased at a steady rate per year from 10,000 years ago to today. There's a feedback mechanism where you have less white -> more heat absorbed -> more ice melted -> less white. So you'd expect the warming to accelerate over time. There are lots of other factors besides albedo at work, which is what makes modeling climate change near impossible and certainly unreliable. As pointed out, we had a serious period of global cooling in medieval times, and the earth was MUCH warmer than now during the times of the dinosaurs.

Asphalt is extremely efficient at trapping heat (it's also very dark), so that might be man contributing to warming by speeding up the feedback loop. There sure is a lot of asphalt everywhere. Clear cutting forests and especially rain forests removes a LOT of trees that breath in CO2 and breath out O2.

Holy cow, us humans are now the source of galaxy warming. Al Gore & Company may have been fully discredited now on our earthly global warming, but now he has a whole new agenda.

The first one doesn't mention perturbation or the actual cause of the warming, just that it is warming. The second one suggests dust storms, which is still an essentially closed system and doesn't help my case. The third one mentions perturbation almost immediately.

The albedo stuff is scary, I had heard about that a little while ago and it makes me wonder what point it switches from accelerated heating to cooling.

 

[Denny Crane]

They say that dust was the cause of numerous ice ages in the past. Dust contains iron, and the iron feeds algae that grows enough to influence the CO2 and O2 levels.

Fwiw

water means life maybe

 

[jlprk]

Republicans think that by showing natural causes of global warming, it makes a difference as to whether humans should spend billions on technology to slow it.

But even if global warming isn't man-made, it will still push coastlines inland, totally change the best latitudes for each crop, and cause millions of Americans to migrate northward. So we should manage it or at least slow it, to give us centuries to adapt, not just years.

In summary, even if you're right, you're wrong.

The Mars picture is a computer creation (with enhanced colors) which changed a vertical photograph to a horizontal angle. The widest parts of the stripes are 15 feet wide. The stripes stay for the summer, then disappear in the winter, just like melting ice would. The temperature at this location prevents thawing of carbon dioxide or water, unless the water is saltier than Earth's oceans. So if it's flowing liquid, it's briny water gurgling from underground ice. But the scientists say that it wouldn't leave the dark stripe, and even if so, the stripes wouldn't disappear in the winter, as they do. So it's unexplained until they come up with a theory.

The significance is that on Earth, microscopic life hibernates in ice until the water turns liquid in the summer. On Mars, ice has been directly detected, but liquid water has not, unless this is the first time.

Does anyone else have an image in their brain of Martians saying to each other "Those dumbass humans FINALLY found the water.....Sure took them long enough"

And then they laugh it up, while working on the next prototype of us. The universe is very bizarre.
