Writing about drying the Colorado River and the ancient Mars.

"Water managers have overestimated the Colorado River’s water supply because warmer, drier springs reduce rainfall, causing plants to consume more of the snowmelt instead of it reaching the streams. New research shows that nearly 70% of the water shortfall is due to this shift, challenging current water prediction models." ScitechDaily, Vanishing Water Mystery: Scientists Uncover Why the Colorado River Is Running Dry)

Let's start with the Colorado River which has less water than should. There is the possibility that warming temperature increases vaporization. But, what really happens? Some parts of the Colorado River flow in the canyon. When the temperature around the thin Canyon Valley rises. That temperature rising causes the air around the canyon to start to rise. That decreases the pressure in the canyon. When the pressure decreases. That decreases the boiling point. 

When water flows over some stones. That causes an effect. Some part of the water flow is in low pressure. When water direction travels over some other water layer. That can cause even a vacuum between those layers. And that means the water will boil at a very low temperature. When air will not push water back into the flow. That releases water molecules into the air. So maybe low pressure in the canyon has some kind of role in this phenomenon. 

And then to Mars...

"Pale rocks found on Mars by NASA’s Perseverance rover contain kaolinite, a mineral that forms in warm, wet environments, suggesting the planet may have once been much more hospitable to life. Scientists are intrigued by this unexpected discovery, which hints at a wetter, potentially life-supporting past on the Red Planet. (Artist’s concept.)

The rover picked up an interesting stone on planet Mars. That stone has been under ancient water. And it can hold the clues of life. There is the possibility that some of those stones that were underwater in Mars's past can hold the bacteria remnants that can recognized as bacteria. 

Today planet Mars is a cold and hostile place. In the past, there could be some kind of prokaryotes. The meteorite is known as Allan Hills (ALH) 84001. 

There are stones on Earth that can be from the planet Mars. There are some structures. That looks like some kind of bacteria that can form the chains. The counter-argument is that those structures are too small being modern bacteria. But when we think about the first primitive organisms they didn't have mitochondria or nuclei. 

Electron microscopy revealed chain structures resembling living organisms in meteorite fragment ALH84001 (Wikipedia, Allan Hills 84001)

They were prokaryotes that got their energy from geothermic temperature. Those very primitive organisms did not have all the organelles. That modern bacteria have. So that causes discussions about those structures of the Allan Hills 84001. 

The origin of those bacteria is unknown because when those meteorites came through the atmosphere. When those meteorites impact Antarctica there is the possibility that this temperature made some bacteria travel to those meteorites.
