ok, this has been bugging me for a while now, but I haven't seen any real conclusion to it.


According to most (if not all) models, global warming will result in first a heat wave and oceans raising, but then an ice age.

So what happens then? I have seen almost no discussion about that, but it is incredibly important.

The rising oceans are because the ice caps melt, but if the ice caps melt and the oceans rise, it causes an ice age. And when you have an ice age, there is a hell of a lot of ice, right?

So wouldn't it stand to reason that shortly after the ocean levels rise, they fall back down again, since a lot of the water would be re-constituted into new ice as temperatures fall?

And what would the new ice result in? If such an event occured, then the pooling of fresh water that caused the "ice age" in the first place would be refrozen within about 2 years (based on models I have seen of polar ice freezing and melting), and the global oceanic currents would return to normal.

The ice that formed would be almost the same mass as before the whole mess started, plus change (meaning more reflective surface, slightly cooling the earth).

Of course, that is all based on speculation, since I have not been able to find a good model of what exactly would happen when the predicted events occur. But I still have no idea why this isn't getting any talk, since many scientists are saying we are past the point of no return anyway

I would think you are right, the levels would fall again though I have no idea what the timetable might be. And when they fall the northern hemisphere will be mostly covered in ice/snow and pretty much too cold for modern populations to inhabit.

That surface area of our current land would reflect a lot more heat out than was done before when that ice/snow was concentrated on the caps.

I think there aren't many models on what happens next because either scientists are focusing on trying to figure the how of an upcoming 'ice age' or feel there is too much they don't know to try and figure out what happens after when 'after' is a dramatic change for the world. Also 'getting' the word out or trying to effect change or whatnot might be at the forefront of their agenda over figuring out what happens after when they will likely be dead, but I honestly don't know.


My guess is the time table for the ice age coming then water reconstituting to ice and snow at levels to restore the ocean as it is for 'our' current range might take decades. I have no clue, I've only seen a scant few depictions on the subject but those all pointed to cooling/warming taking decades if not centuries, though there were anomalies IIRC.

I know for a fact that would not happen, since the models have predicted that stuff.

It puts the midwest at a much warmer climate, like that of florida. Europe's position is a bit worse, where it would get very cold.

But as I said, this could not last very long. By definition, the ice would re-accumulate at the caps very quickly, and that would re-distribute the flow of water that caused the cooling in the first place to the point where little difference could be seen from the initial movement.

In other words, if global warming causes the change that it predicts, global climate would have a massive fluxuation for about a decade, then return to "normal". I don't see how it could work otherwise, unless there is some massive oversight I am making. But based on what I have seen, such is not the case.


And having the entire northern hemisphere uninhabitable is not likely at all, since the southern hemisphere is just as large and prone to change. That scale of temperature change is impossible by any standards, especially since there would still be the greenhouse effect to figure in.
