Global warming - Water shortage or water floods?

Question

I study Geography in school and I am wondering. Global warming is causing water shortages as water runs dry. Global warming is melting ice on the two poles and sea level will rise. So are there too much water or too little water?

By the way there's something called desalination though it's a lil' expensive

Answer 1

I question any statement that says water runs dry. I think water shortages are caused by more use of water, not less water available. If there are 1 million gallons a day available from a source, then any use above a million gallons a day can be called a shortage even though there is no reduction in the million gallons a day available. As the population grows, more farm land is needed. All the good land with enough natural rain is already taken. So the new farms are in areas with less rain. Naturally, this is called a shortage. But the reason is not less rain; it is more farms in new and less desirable areas.

I also question that global warming would cause water sources to actually dry up. 70% of the Earth is ocean water and that will not change. Hotter weather will increase the evaporation rate from the ocean, meaning there will have to be more rain because the air can only hold so much water vapor. So global warming should cause more rain, and there is no way that would cause land based fresh water sources to dry up. They may be talking about shifting rain patterns, where places that used to get lots of rain start getting less due to shifting wind patterns. But other places would have to get way more rain, because the total amount of rain in the world would have to go up is evaporation from the oceans went up. Now, do you trust the climate scientists to tell you where it will rain and where it won't? Keep in mind these are the same scientists that tell you that it will not rain tomorrow and then it rains hard anyway.

Answer 2

Global warming will lead to increased evaporation of the moisture in soils, thus increasing the demands on irrigation. Another huge source of concern is the changed weather patterns -some believe the droughts in Africa in the last decades, which were cause when the seasonal rains failed, was because of the changed temperature. Global warming is leading to rising sea levels -roughly 3 mm/year. If the major glaciars, such as Greenland, would melt it would lead to a significant rise -6.5 meters.

Answer 3

Salt water and fresh water are different.

Currently, California is experencing water shortages because of uncontrolled immigration. Normally, the state could handle a drought. Unfortunately, the state now has 10 million more people since its last drought a couple of decades ago.

California either needs to build new dams. Or ignore eco-freaks and build G.E. desalination plants (remove salt from sea water) like the ones used in Europe.

Answer 4

The water shortage isnt one of water throughout the world, its a lack of freshwater, we pump too much fresh water and then it goes to waste, like evaporating and such and it is lost from the water table, so the oceans may rise but we cannot drrink it without extensive processes called desalination to get the salt out.

Answer 5

both and neither.

when it comes to global climate change, it is speculated that we will see an increase in the speed of the H2O cycle.
this increase means it will rain more, but plants will benefit less, because it will evaporate much faster.
and as mentioned aboved, this will lead to the depletion of water tables, which is what will slow the ill effects for a short time, until they become depeleted.
this is what occurs in some deserts. if you have ever lived in one, you would notice that it rains far more than you would expect, but rarely does it rain across large areas like we see in other climates.
this is because it rains, evaporates quickly and rains again. once in a while you get a large cloud burst followed by flood but the water still doesn't stay around long to benefit wildlife other than what has adpated to live in such and environment, much.

Answer 6

the usual thing sit and watch we are accustomed on that so almost all the world took us for granted that we are not moving things around or the masters of our selves or at least have a free will look at a Small;group in Lebanon with some will and some leadership made the whole world respect them but not certain groups of Arabs who would not what do we do about global warming? the late king Husein of Jordan was not a leader of a big nation but he was involved in all world activities i am sorry to say it we are loosing so many things that the other generations fought for even lastly in haikal weakly speech he said that the british has took the "manbar" of al azhar as it is a nice piece of work did any one claimed it as theft?? and they must return hitler stole from russia but all were claimed and sent back plus for more vital things we are not moving a finger

Answer 7

It depends on where you are. There will be more local variations in the future so some regions will get too much rain, some not enough and there will be a general trend of sea levels rising which will threaten coastlines worldwide.

Answer 8

There will be both water shortages in some areas and flooding because of excessive precipitation in others.

Answer 9

Global warming is Beelzebub to liberals. It can be blamed on everything bad from mutated frogs, to droughts, and floods and nothing good comes from it. Remember, Gaea is the only god and Al Gore is her prophet.
