NASA Satellite and Arctic Ice in the Beaufort Sea - Page 2

Felloffher, that was depressing. I'll have to watch part two tomorrow.

"But the cubes melting in a glass of water don't change the water level. therefore, SEA ICE melting in the sea, won't change the sea level. It's normal for sea ice to form and consequently melt seasonally. Happens in the Bearing Sea every year."

Wrong. Do the research.

Our planet has been going thru these same variable changes since the beginning of its creation
look back to the ice age
it covered the northern hlf of the planet and mow is stlll regressing causing crazy effects world wide
whe I was 13yrs old icecisles hung off my house. In Galveston in april
​now last. Year it snowed in April in Tyler.  Hot one day frost the next but
no more ice days
Texas has always had weird weither patterns and severe storms
The pattern of wait minutes and there will be a change
Is still the same
 

It's nice to hear from the lone star state and welcome Rose.

I think while these cycles have history there is still a difference due to mans activities that has yet to be fully understood.
We are an unknown added to the mix and haven't a clue what long term effects we create.
Not that we make it happen but we complicate it and certainly cause harm.
 

Actually, sea ice melting into the sea should lower water levels because ice has higher displacement/volume than the water that forms it, like the plastic water bottle that pops when frozen.  Melting land glaciers are the problem because they increase the total amount of water in the ocean as they run off.  If there is more moisture in the atmosphere, why are we having droughts?  I have heard that some warming will be helpful because it will prolong the growing season and more food can be produced.  One of the biggest problems of impending overpopulation is predicted water shortages which all this melting may postpone.  Look on the bright side.  We will adapt and clever people will make a fortune off of new technologies.  That's evolution, isn't it?  I'm more concerned about North Korea/China, sun spots and the grid, and asteroids, the kinds of things we aren't planning for.

Micaho,

Do the research. I do not have time to explain it just do the research.

I really don't believe ice ages are cyclical nor man caused and instead are caused by major planetary events.

Gsdadmin, thank you. But are you saying, "wrong", that the level in the glass doesn't change? 'cause it doesn't. Or that it's not normal for sea ice to form and consequently melt, seasonally? Cause it is normal.
Or, and this is probably what you were exclaiming is my error, that melting sea ice doesn't raise sea level ?
That's a bit more complicated because of the nature of frozen salt water, which has a characteristic called brine rejection. So, no salt in ice crystals. When the ice caps melt, they freshen the sea water, which lowers salinity thus causing lower density and increasing volume. Increased volume causes sea level to rise, which the current rate is estimated at 3.1mm or 1/8 inch per year due to sea ice loss. Pull on your waders, grab your snorkel, 'cause you're going under! LMAO

Correct GSD
neither are volcanos.  , earthquakes but cause earth horrors 
man gets technology in the middle

Why are we having droughts?
Because the weather patterns are shifting along with the jet stream.
There have always been dry places but this movement relocates the effect.
Water vapor in the atmosphere does not mean rain or that it will reach the surface, it means green house, holding heat in.
Technology is not evolution nor the solution, and I don't see any planning of long term solutions.
Except in the area of over population, I believe there are plans to address that issue underway as we speak.

 

Bingo but your numbers are off. BTW, ask places that are at or below sea level how this will affect them. Now add this displacement to the melting glaciers and you have problems. Time will tell and most of us will not be here to see it. More open water will also cause more moisture in the air and we can figure out what will happen next.
