would it have a catastophic effect or perhaps counteract global warming and the rising sea level?

Short answer: nothing would happen.\n\nLonger answer:  Think of it like this.  The oceans make up 2/3rds of the surface area of the planet, approximately.  They are much, much deeper than tall buildings, trees, or even mountains.  Also think about water displacement- the volume of water that something displaces is equal to its own volume.\n\nRising sea levels are caused, mostly, by melting polar ice caps.  So how big are these ice caps and how much is melting?  The ice caps cover the Arctic (the size of a major continent) and most of Antarctica, which together is probably the size of two major continents.  Worst case scenario- most of it melts.  Let's be optimistic- 10%.  Can you really imagine the boats that we have adding up to 10% the volume of an entire continent, let alone two?  No, it's ridiculous.  A mountain or two, sure, plausible, but something the size of Texas?  No.  Absolutely not.

It is indeed a threat...But so is global warming....have you noticed the weird weather lately?

Any energy liberated by a reaction is indeed heating up the planet.\nHowever, the real problem with global waming is the amplification caused by green house gasses, like methane and CO2, wich traps the heat from the sun.  The sun gives about 1300 watt per square metre, over the surface of the planet this is over 10000 times more energy than all the installed power (the sun energy hitting earth is equivalent to 27 gigawatt per person on the whole planet; no one uses that much power). So, doubling our power production would have a negligible effect on global warming, but adding just a bit of gas that traps the huge amount of power that the sun sends will, however, have a huge impact.

Global warming and cooling, in nature, has cycles beyond our control. AS a species, we have vastly accelerated the warming by CO2 emissions from burning of fossil fuel. The CO2 is/has formed higly reflective shield around the globe that holds heat IN, yet allows sunlight to go through it. The heat builds up, but cannot escape fast enough to prevent warming of the planet. We have reached a critcal stage in this cycle. IF we do not greatly reduce CO2 emissions within the next 10 years, it will be too late for us to stop the cycle that has started. Ice caps will melt and the surface of the Earth will change drastically. Storms will intensify dramatically, having more and more heat to power them. WE are within just a few years of a catastrophe, and yet, no one seems willing to act upon it, in fact, no one seems to even acknowledge the pending disaster. Life as we know it will be very different than it is today. WE are, time wise, just around the corner from a life threatening climate which will be conducive to an instant ICE AGE. If you have any doubt, see the movie, "Day After Tomorrow." The premise of the movie is NOT sci fi...it is very real.

Flood the coastal regions.\n\nIf it's global WARMING, it's only going to trap the heat inside the ozone layer.\n\nIt also depends on what time of the year it is. The closer to winter it is, it might make a new ice age if there's enough water, which I think there isn't.\n\nThe chances of coastal regions flooding is greater than that of a new ice age.

Yes, we have affected and been affecting our Mother Earth largely!\nEvery road disturbs the natural ways of animal movements.\nOur use of certain chemicals destroy sections of the atmosphere.\nCreation of cement cities lowers the natural beauty!\nNuclear tests are changing regions.\nProfessional fishing eliminates kinds of sea life.\nand so on!

Apparently, lesser sunlight will get in. That will cause some imbalance on earth.

Since 70% to 75% of the Earth's surface is water, I would think it would make less of an impact than if they were just left on land.  There are so many billions of ocean creatures that would flourish off the food supply that would be provided by such a terrible catastrophe.

Actually, global warming would lead to stronger storms which make larger hail. I think this idea you have said about hail decreasing in size over time is wrong because it doesn't make much sense.

Extremely unlikely. A lot of time has passed, and within that time, the structure has shifted, pieces of it have collapsed and sunken, and the metal is slowly being eaten away.\n\nSurely any attempt to raise the infrastructure from the surface is going to make it collapse and break apart in numerous ways. The Titanic's remains has been erroding away steadily over the years, and eventually there won't even be much left of it.

I think it's gonna be real cold.  Like Michigan (where i live).  But no, If it is in fact a ice age, that means that  huge amounts of water  are frozen into glaciers (and because we only have so much water on earth) sea levels will actually go down because water is locked in the glaciers.  Global warming causes glaciers to melt and hence rises sea level.  And by the way, we are still technically in an ice age (we still have huge ice sheets) we are in what's known as an inter-glacial period.  The last glacial maximum was about 22,000 years ago.  Sea levels were so low that humans could walk across dry land from Ireland to Britain then to the mainland of Europe! Check out a map!

OMG...this is a very sad question. The reason why gloval warming NEEDS to affect the earth is because without it, we would all DIE. Think about it, what would we do if there was no heat at ANYTIME. We would all die because we would all freeze to death. Besides in order to keep anything alive we need Gloval Warming. The food we eat need it, the water need it, the plants, animals everything and everyone needs it.

No Definitely not. Man could never tame or alter the path of the plates. However I do believe he may have alredy implemented change on the Convection currents. Global warming was probably helped by man during the Industrial revolution and has gone on ever since. Dont just blame America. I have seen some appalling instances of Major pollution in India and several other third world countries. It is a global thing and all countries of the world are guilty of some form of pollution.

Few complex life forms we know of can survive exposure temperatures that low for more than a moment. However, if pockets of milder temperatures could be found (thermal vents, well isulated hybernation dens, etc) some life would likely adapt. Life forms that could mature and reproduce in one warm season (such as a plant that produces spores capable of surviving such a harsh winter) would have a great advantage. Plants such as trees woudn't stand a chance, as is true of many things humans and other complex life depend on for food and shelter. \n\nAnother consideration would be the erosion due to lack of any plants capable of maintaining a root system to stablize soil. Between the turbidity from erosion and likelyhood that all rivers would freeze solid through most of the winter, most life in rivers and lakes would become extinct. Since the upper temperature is not much if any higher than what we have now, the average temperatue is much lower. This would concentrate vast amounts of water in the icecaps, possibly enough to greatly increase the salinity of the oceans, which would also see a major drop in temperature. Most marine life is more sensitive to temperatue changes than terrestrial or freshwater life, so a great number of extinctions there also.\n\nSo no, life would not survive other than perhaps a few simple life forms. Even a drop of a dozen degrees in average temperature would be devastating in the long run for life as we know it.
