1. In a tsunami or storm but not worldwide.
2. No. Nothing happens instantly, but freezing cold has little effect on machines.
3. Yes, but rarely.
4. New York the state or the city? The city is so large that there could be perhaps 6-8 from 3-4 seperate storm cells.
5. Only if the programmer feeds in the correct information and is very lucky. In a practical sense, no. There are too many variables, which require constant corrections which change the prediction constantly until the flow of correction equals real time.
6. During tides and earthquakes, yes. Some sections upstream drop to a lower level than downstream areas.
7. You can get frostbite that quickly at -50 F and if naked be dead within minutes, although not frozen through for a longer time.
8. Check Guiness Book of Records. All I remember was that it was BIG.
Don't pay attention to disaster movies, they are so unrealistic. It's all special effects and Hollywood suspense and shock. Like the movie where the people had a heated pool, using energy like water, while the nation was freezing and within moments the glacier was pushing down the wall. Such garbage.

1: Can the ocean rise by 25ft in a matter of seconds?
yes in a tsunami
2: Can a helicopter freeze instantly?
anything below temperature can freeze!
3:Can it hail as large as tennis ball?
I've heard the size of a golf ball, but let's face it anything possible.
4:How many tornadoes can there be in one place, say the size of new york?
It all depends on how the wind shifts and how powerful it can get, but haven't really seen or heard of a tornado the size of NY
5:Can a computer model predict the future?
NASA is always looking down from space and they can tell from their eyes what we cannot see down here. (wish I would of stuck to it...NASA)
6: Can the current in the water quickly switch direction?
Yes all the time, just go to the beach and study the waves
7: Can people freeze in under 30 seconds?
I would not be doubt, some people though can adapt to the claimant changes, depending on age, size, & health.
8:What's the largest recorded hailstone?
47.6-centimeter
I do believe that The Day After Tommorow" was made to give us all a reality check on the impact of Global Warming and what we could face if we don't change our way's...detroying the planet.

1: Can the ocean rise by 25ft in a matter of seconds?
No it can't, the seas and oceans are currently rising by about 3mm (one eighth of an inch) per year. In open waters the seas and oceans frequently swell by this amount but that's harmless as anything in the water just bobs up and down. It's only when waves of this height start breaking that there are problems - in the open waters this occurs on severe storms, on land it would require a major event such as an earthquake to trigger a 'tidal wave'.
2: Can a helicopter freeze instantly?
No. Helicopters can operate in very cold conditions and it's often the wind that's the biggest threat. In rare circumstances an ice storm could bring a helicopter down, this is where freezing rain falls on surfaces (including helicopters) and immediately turns to ice. There was such an ice storm in Canada in the 1990's and it did bring helicopters down but the pilots had some warning and were able to land.
3:Can it hail as large as tennis ball?
On rare occasions this has been known but these are freak weather events that are associated with thunder clouds. There's probably one or two hailstorms with tennis ball sized hailstones each year, it's only when they hit populated areas that there's a problem. A few years ago such a storm hit St Louis and caused a lot of damage, fortunately no one was injured or lost their life.
4:How many tornadoes can there be in one place, say the size of new york?
A 'tornado outbreak' as they're known, can see several tornados touching down in the same area in a short space of time. They're not particularly common but they're not that uncommon either. The worst tornado outbreak occured in the 1970's and covered much of central US, there were 144 or 148 tornados that touched down (can't remember exact figure) and several of these were very intense.
In an area the size of New York it would be possible, although unlikely, for perhaps half a dozen tornados to be on the ground at the same time.
5:Can a computer model predict the future?
Computer models are extremely complicated, they need some of the most powerful computers to run them. This is because there's a huge amount of information required and sometimes the information entered into the model is wrong, this causes errors in the predictions. Whilst they generally give us an insight into the future they're far from precise. It's a bit like weather forecasts - usually they're close but sometimes they can be miles out.
6: Can the current in the water quickly switch direction?
Ocean currents can switch direction but not quickly in the sense of hours and minutes. They can switch quickly in terms of how fast things happen in nature but this would take several years.
7: Can people freeze in under 30 seconds?
Yes if they're exposed to extreme conditions. In the most inhospitable parts of the planet exposed flesh can freeze in seconds buit it requires at least two of these three factors - wet conditions (snow, sleet etc), very strong winds, extremely cold temperatures. Mountaineers on the world's highest mountains and explorers in the polar regions have to be careful not to expose any flesh when the weather becomes extreme. It's not something that could happen under ordinary circumstances.
8:What's the largest recorded hailstone?
There's a picture of it here - http://en.wikipedia.org/wiki/Image:Hailstone.jpg it was 7 inches long and 19 inches around.

: Can the ocean rise by 25ft in a matter of seconds?
Yes it's called a wave
2: Can a helicopter freeze instantly?
Almost - (nothing is instant - e.g. taking no time at all)
3:Can it hail as large as tennis ball?
Yes - planes have been damage or destroyed by such
4:How many tornadoes can there be in one place, say the size of new york?
Ney york state or city - well loads if you include the tornadoes at the edge of a hurricane
5:Can a computer model predict the future?
Yes - anybody / thing can make a prediction - some may even be right - given enough predictions the chances are one of them will come true - computers are used to predict the next days weather
6: Can the current in the water quickly switch direction?
Yes - see river eddies and whirlpools
7: Can people freeze in under 30 seconds?
Yes if the fridge is cool enough or you were deposited in deep space sans space suit
8:What's the largest recorded hailstone?
No idea - check guiness book of records

1. Tsunami hitting shore, yes. Massive increase in the volume of the ocean, no.
2. No.
3. I've seen pictures of this, yes.
4. NYC or the whole state? A tornado is a result of two weather systems interacting, so there could be several along the weather front, but only two really near each other.
5. Computer models are notoriously flawed. There are too many variables that we don't understand, so we can't program a computer to accurately take those things into account.
6. Water currents are driven by temperature (air and water temps), lunar forces, and submarine terrain, among other things. So no, other than the changing direction when high or low tides max out, there's little chance of water just "turning around."
7. You mean frozen solid? No. Our core temperature is quite high, and our bodies respond to cold by limiting blood flow to the extremities (hands and feet) to keep the blood from cooling too quickly. It takes some time for the body to freeze completely; freezing to death can happen in under half an hour, but freezing solid would take a bit longer.
8. The largest hailstone was 17.5 inches around, and 1.67 pounds. About the size of a melon.
Hope you get a good grade, whatever you're working on.

1. It can and DOES in a FEW locations around the globe (The Bay of Fjundy, being one such example, Search for Tidal Bore). but NOT the enitre ocean. Global warming will NOT occur that rapidly for the oceans to rise that much in a short time. (By human standars)
2. Only if it's dropped into a LARGE pool of liquid Hydrogen or other liquified gas component of air.
3. YES, I have personally seen hail as large as Grapefruits, did a LOT of damage too. Busted my daughter's car windows and dented her car up pretty badly as well.
4. A large number of tornadoes can from from ONE particular storm cell. I've seen as many as six or seven at one time in a 10 mile area.
5. A computer model can only predict something based on the total amount and quality of the data entered. Presently computers are doing fairly good at predicting storm intensities, direction and rate of movement. But when extrapolated over a long period of time the models become less accurate.
6. That would depend on the SIZE of the body of water, the air speed at the surface and whether or not anything siesmic is occuring on the floor of the water body. At the Bay of Fundy, when the tide comes in, the river actually runs backwards for an hour or so.
7. Yes, at temperatures of lower than -50 F human skin can freeze in 30 seconds if it is exposed to the air.
8. You have me there, but I've HEARD of hailstones as large as watermelons. VERY rafre and there has to be a VERY strong set of updrafts in a VERY strong storm cell for that to occur.
Hope this helped,

None of that is true.
Global warming won't be a Hollywood style disaster. Gradually coastal areas will flood and agriculture will be damaged. But it will be very bad. Rich countries will cope, but it will take huge amounts of money. In poor countries many people will die of starvation, but not all of them.
Most scientists say, in 20-50 years. But we need to start right now to fix it, fixing it will take even longer than that.
