this global warming thing....?

Question

the ice caps melt, the sea rises by ( 1 to 3 meteres ).
Water puts pressure on the sea bed? the sea bed sinks under the pressure, the land is pushed upwards.
the volcanoe's go boom, the earthquakes show what they can do????

are you frightened???

yodadoe... are you saying that 9 to 12 feet of water.. over the whole ocean, will not have a dramatic effect on the earths plates????

Answer 1

terrified....i will never sleep again

Answer 2

Okay, most of that is not correct. A few meters of water on top of the sea bed will not be nearly enough weight to push the oceanic basalt any deeper into the mantle below. The only vertical movement of the lithosphere (earth's crust) would be the rise of some land masses if large amounts of ice melted off of them, i.e., Greenland and Antarctica. The main thing we have to worry about is sea level rise. Considering that the majority of the population of the world lives along coastlines, flooding becomes a major problem.

As for volcanoes and earthquakes... those will be mostly unaffected by the atmoshperic conditions of the planet. They get their "directions" from beneath.

We also will have to deal with many less-predictable problems. Changes in the atmosphere will (and already are, to some extent) change the weather patterns worldwide. Places that used to have rain (and grow crops) will dry up. Other places will be deluged with more rain. Changing local climates will kill off animals and plants. So yes, you should be somewhat frightened. Not "Armegeddon" frightened. But "poverty and starvation leading to wars and strife" frightened.

ADDITIONAL NOTE: Yes, I am saying that a few meters of extra water will have a negligible effect on the oceanic plates. They are about 3 times as dense as water and are sitting on top of an equally dense mantle. There is simply nowhere for the oceanic crust to go in the downward direction. You cannot think of the crust as a layer of solid on top of a liquid like water, which would be pushed out of the way (and thus push the continental crusts upward, as you think). The only discernable vertical movement of crust from the placement of water is when large glacial masses melt off of a continent. But we are talking glaciers that can be up to a mile thick. That much much more than a few meters of water. If I remember correctly, Hudson Bay in Canada used to have a huge glacier on it. After it melted, the entire area raised up. It may still be rising very slowly, but I can't remember for sure.

Answer 3

I´m not frightened be the facts.... they are known for years. I´m frightened of the lack of interest the people in this country show towards this topic.
And to correct your question... to melt the ice shield of Greenland the global temperature just has to rise by 2 degree.... but this would mean 6meters higher sea... just have a look what this would do to New York
this will be the point where 9/11 becomes a pinprick compared to the amount of people that´ll die after this... (i´m from NY, so don´t think that I didn´t suffer as everybody)
The fight for the climate should be the fight we´re fighting.

Answer 4

Planet Earth has been warming and cooling since time began and will continue to do so the seas are so vast even if all the ice melted they would only rise perhaps 1 metre

Answer 5

Yes, I'm very frightened about global warming, though scientists are now in the process of looking at the effects of the suns effect on global warming as its been one of the main contributors, I don't think the human hand had helped much either, we could all recycle more and have solar panels on our roofs for heat and not water, but as much as most of us would love to do these things the government and councils just do not seem to want to get us interested in it and poo poo every idea that comes their way then pass the buck, I feel for the future generations and what they will have to put up with because of our lazy intolerant governments and councils of this country and all the people now who refuse to recycle because they think its beneath them.

Answer 6

Yes I am. But people never seem to realize that and they take Earth for granted. So here is global warming. Glad that there're still some smart people who know that global warming exists and trying to combat it. But sadly,most ignorant people just live in their own worlds. By saying most,I mean MOST of the people IN THE WORLD.

Answer 7

Hey! the scientist will keep saying things that keep them employed.We are not sure about these findings that seem inconclusive,so give us more money so we can study it some more.On another note doesn't water evaperate when it gets warm out side? Think arizona.

Answer 8

Not really, no. Seems like a waste of time to worry so much about a solar event we can do very little (if anything) to stop.

Answer 9

A tad, I know this sounds selfish though, but I'm going to be dead when all this kicks off!

Answer 10

Yipeee........i can feel good about keeping the 4*4 now !

Answer 11

No, not at all. G W Bush isn't concerned, and if you can't trust a US president funded by the Oil companies, who can you trust, eh?
