I have a question for all those scientific Freepers.
In a world where most of the surface is water, doesn't global warming mean more evaporation and hence more fresh water (i.e. rain and snow)?
And won't the resultant rains serve to cool said planet.
There is no Global warming at all. The oceans are the same temp or lower when aggregated. The satellite data is very telling. There is no temperature differential above 150 miles since 1957— none. You will see minor regional variations but when averaged temperatures have gone down. Global warming is a false god worshiped by evil people. always remember this law of physics. If you displace a beaker of water with ice cubes and they melt— guess what happens to the level of water? The same. Ha these people are flat earth people!! Total myth and fantacy. They are folding up their tents.
“In a world where most of the surface is water, doesn’t global warming mean more evaporation and hence more fresh water (i.e. rain and snow)? And won’t the resultant rains serve to cool said planet.”
The ‘evaporation absorbs energy (cooling) and the
formation of rain drops releases energy (heating).
And what happens when the rain drops hit the earth?
“And what happens when the rain drops hit the earth?”
It goes ‘splat’!
“If you displace a beaker of water with ice cubes and they melt— guess what happens to the level of water? The same.”
The ice being referred to here is on land, not in the water. When it melts in runs into bodies of water.
So how much influence does the water vapor have as a greenhouse gas?
Heat creates the transfer from water to vapor...which then rises.
And the cold upper atmosphere causes the vapor to become solid water...and then rain.
I don’t have a greenhouse...but when I get one, I’ll let you know.;-)
“I think you have it backwards.
Heat creates the transfer from water to vapor...”
That is what I said. REREAD my post.
Well, you sir should get with the program!!
It is not Global warming-
That changed years ago to Global CLIMATE change-
The New official title- Global climate Disruption!
Currently working on a new name - to keep the millennial’s
interested.
LOL
Didn't see the obvious meaning of it...but then I often miss the main message.
Sorry.
Please expound.
Is this a fresh water question, or a "global warming" question?
both are extremely complex and attempting to grasp all the factors involved individually is an impossible task. Trying to understand them together is impossible squared.
Ask any real scientist if he or anyone else fully understands all the factors, interactions and feedback mechanisms that determine long term temperature trends (that's what climate is, by definition) and if he is competent and honest, his answer will be: NO. No one and no group knows!
That is why not IPCC reports are comic books in disguise. The Science is done by scientists, but the final report (the Executive Summary) is done by politicians. Politicians then order the scientific findings and expressed uncertainties modified to agree with the political conclusions.
Just think about all the computer models trotted out over the last 30 years. Every single one fails the simplest test. They fail accurately to predict a past 10 year period trend, having been fed the temperature data from the previous ten or 20 years.
At the bottom line, it is quite simple.
Unless you are a democrat. And I know you are not.
“And the cold upper atmosphere causes the vapor to become solid water...
Please expound”
Correct. This heats the earth!
Water cools the earth.
Ok do this. take a glass of water and put a large rock at the bottom. Then fill with ice. Let the ice melt. What do you see? It is the exact same displacement. Go try it.
Not in the way you’re thinking, no. Water IS an evaporative coolant, but what that means is that by evaporating, water absorbs heat energy from what is around it, becoming warmer but cooling its surroundings. This is why sweat cools you when you’re hot. However, thanks to the First Law of Thermodynamics, no actual ‘cooling’ occurs... yes, YOU get cooler, but the sweat (water) gets warmer by an equivalent amount, so the net remains zero. If we had more rain, and more water, we might get some more evaporation, but all that means is the heat is getting shifted around.
There IS, however, a school of thought that suggests that global warming will change the atmosphere’s reflectivity (via clouds, etc) in a negative feedback loop. Warm air can hold more water. Wetter air means more clouds, and clouds reflect more energy to space than they keep in. So... planet warms up, more clouds form, more sunlight reflected, planet cools down, less clouds, cooling stops. Bingo, instant climate-controlled planet!
To be honest, this is a much more reasonable hypothesis than the idea that somehow Earth ‘lucked into’ the exact right temperature, and minute changes in the atmosphere will send us hurtling in one temperature direction or the other. The climate alarmists believe temperature is like a ball sitting on a peak... push it off in any direction, and it just speeds off in that direction. I believe temperature is a like a ball sitting in a trough. Push it in one direction, and the forces of equilibrium conspire to nudge back to where it started.
We remain at roughly the same temperature through the millennia because the Earth self-corrects, and the only thing that REALLY effects long term temps is solar output (i.e. putting more or less energy into the system to begin with).
Hope that makes sense!
Until the "I believe" part.
Do you have proof or don't you?
“Ok do this. take a glass of water and put a large rock at the bottom. Then fill with ice. Let the ice melt. What do you see? It is the exact same displacement.”
Your analogy is flawed. Fill a glass of water. Place a screen on top of the glass. Place a large ice cube on top of the screen so that when it melts the water drips into the glass. What would you see?
