If what people predict about global warming is true, will we live in a waterworld?

Question

I hope Kevin Costner isn't there.

Do you think the human race will evolve to have gills?

Will we build underwater kingdoms?

Could we just put our houses on pedastles/pilars?

Answer 1

if we do i have a killer bathing suit that i can wear it's hot!

Answer 2

To begin with I doubt seriously that the global warming scare holds any more truth than the global cooling scare we had in the 70's. This planet goes through cycles. There has been hot and cold periods all through geological history. Yes even before the nasty internal combustion engine doomed us all to extinction.

But let's say it is true. All the ice melts and it raises the sea level until coastal cities are under water. We, the human race, will survive. We will change our way of doing things, we will adapt. Not by growing gills. I suppose that could happen but it would take a few million years for such an evolutionary experiment to take hold. We would simply move inland, move to higher ground, farm differently and oh yeah, a lot of us would die. But those deaths would be individuals, not the specie.

Don't loose any sleep over this politically correct scare that we are having to endure. Listen to real scientists, not Al Gore, or Michael what ever his name is. These people have no credentials but are treated by the media as experts. And not in the fields where they possess some knowledge, that of political science but in the field of real science.

My main concern is more than just having higher water levels. Melting of the icecaps not only changes the sea-level, but the salt level as well. This can be a problem,because not only will the sea level affect weather, but salt level effects the weather as well. Though this theory is just as debated as global warming, global cooling could be a result of sea and salt level changes too. If I had the choice between the two, global warming would be mine. Regarding your question of human evolution and massive civil engineering feats, I consider my odds winning the lottery more likely and practical. Evolution seems to work the other way around where species move from the water to land. Since we are terrestrial warm-blooded species, it would be a a greater change. Whales for example don't have gills and are warm-blooded mammals, there isn't sufficient examples to base this idea on.

Answer 4

Global warming is just a problem of around 200-300 years. But that poses no such problem to the existence of mankind as we are now entering into an Ice age again. Temperatures of the world's cities have dropped by quite a bit during the past century.
Have you noticed that even the hottest a few years back, are now cooler during the summers? But the winter temperatures are decreasing.
I have lived all my life in the coastal town of manipal in South India. The winters here would be relatively cooler than the summers but there was an average temperature of 30 degrees celcius. This winter, the average temperature is around 26 degrees celcius. And this is not the story of only one town. Majority of the cities around the world are showing this phenomenon.

And even if global warming threatens us by increasing the sea level, there will be serious problems anyway.
The water level increasing means the decrease in the level of oceanic salt content. Due to this there will be considerable changes in the weather phenomenon. The Pacific and the Atlantic ocean currents will cease to exist thus decreasing the productivity of fish by almost two thirds.

But regarding the survival of man, Man is a very adaptable creature.
We are already building floating cities. Our technology is of the superior kinds on Earth.

Ever heard of the nexus project?

The Nexus project is a floating city project designed to accommodate 100,000 persons. 7 kilometers long and 4 kilometers wide with the capacity to be mobile, grow its own food, produce its own electricity and, owing to it existing beyond the 12 mile governmental jurisdiction boundaries, create its own government, income system and tax base. In essence, this mobile city becomes its own independent country. The structural material for the project is electrolytic concrete made from seawater mineral salts that adhere to steel rebar submerged underwater with a small amount of electrical current applied to the bar. Over a short time the mineral salts from the seawater accretes onto the steel to form a concrete material. The process is extremely inexpensive and produces reinforced concrete suitable for creating structures. The structure is built underwater and is then floated to the surface when completed. The city utilizes several different types of electrical power generation. Five Ocean Thermal Energy Conversion units are positioned at strategic zones of the city to supply electricity. Banks of freestanding windmills and photovoltaic solar cells produce additional electricity. The "head" of the floating city is a small mountain range with a specially designed frontal structure that cuts Tsunami tidal waves into smaller, manageable waves with little destructive effect. It is a tidal wave barrier that requires the city to head into the on-coming wave. An adjustable set of hydrodynamic "limbs" adapts to the needed amount of marine agriculture garden area depending upon population needs. The "limbs" also reduce water drag when positioned together. The greatest advantage to the city's mobility is that when it rests in one place for a while to exploit the ocean's resources it can then move onward so that that particular area is not depleted and can replenish itself thus protecting and preserving the ocean's bounty. The city grows its own food and is an agrarian-based population utilizing advanced, nature-based technologies that produce no toxic pollutants. "Living Machines" and solar desalination plants create and recycle all water for human use. The city, in essence, is a living organism based upon ocean resources and climate.

Also there is this project called the Freedom ship project which boasts of a city aboard a ship, in short the largest of luxury liners built for permanent stay

And I certainly don't see the human race having gills for atleast a million years as the gills are specialized structures which require atleast a million to evolve. We do possess gills during our foetal life when we are embryos as we have to float in the liquid medium in the mother's placenta. But when we are born, these gills become rudimentary as they are no longer required for our life on land.
Do you know that new born human babies are very good swimmers? Is this because of the gills during development and because they swim for nine months in the liquid medium in the mother's womb? Think about it.

Answer 5

Humans evolve to become "Homo thermos".. Normal body temperature will be 40 degrees Celsius. Humans will not sweat with any temperature. They will need just one cup of water per week.. Humans will need food once in a month. All oceans will disappear and in their place a few oases will be present.

Answer 6

chip some ice into fine pieces, fill a glass, cover with sarhan wrap so nothing get out as moisture. then when melted look at the level in there. if icebergs melt then water level will go down, DOWN!

or if things heat up more water will be suspendended in the atmosphere, water levels will go down.

Answer 7

We won't be living to see the waterworld dear. We'll be dead. Or ... you could grow gills... It's not possible actually. It would be the end of the world.

Answer 8

What people?

Different people predict different things.
