I was watching a show today that said if all the ice on Greenland alone melted, the entire ocean would rise 20 feet. And then they said if all the ice on both poles melted, the entire ocean would rise over 200 feet. Now I am good at math and science so I know that this is a boldface lie. Why do they do this when Global WArming is real?

Its not so they lie but that they are predicting stuff form what models tell them. Garbage in-garbage out. They use data in such a way to prove the model rather than really study the data and see what really is going on.

There is geological proof that the sea levels have risen and fallen great distances over time - at the height of the ice age, people were building communities in places now 40 ft under water (off the coast of India).

During the hot house periods, the central portions of the US was covered by an inland sea.

I'm curious how your math adds up - are you a climatic scientist or a meteorologist? Do you know how much ice volume currently exist? Why don't you post your superior math and science somewhere and compare it to what NOAA or NASA says.

I'd put my money on their instrument while those who throw around the "Alarmist" labels seem to bank with Exxon.

You must have made some errors in your calculations, if you've saved the workings please post them here and I'll have a look at them.

Here's the actual figures...

East Antarctic Ice Sheet
26,039,200km³, sea level rise if it all melted = 64.90m (212' 10")

West Antarctic Ice Sheet
3,262,000km³, sea level rise if it all melted = 8.06m (26' 5")

Greenland
2,620,000km³, sea level rise if it all melted = 6.55m (21' 5")

Antarctic Peninsular
227,100km³, sea level rise if it all melted = 0.46m (1' 6")

Glaciers, snow fields and other sources
180,000km³, sea level rise if it all melted = 0.45m (1' 6")

Totals
32,328,300km³, sea level rise if it all melted = 80.32m (263' 5")

Arctic
Area varies between 3 and 4 million km³, sea level rise if it all melted = 0.0m (it's floating and is already displacing it's own mass of water)

- - - - - - - - -

Rough calculation method: Oceans cover 361 million km², 26 million km³ ice in E. Antarctic Ice Sheet, 26 ÷ 361 = 0.072, multiply by 0.9 as ice is less dense than water = 0.0648, multiply by 1000 to convert to km² = 64.82 metres (pretty close to the more accurate figure of 64.90m)

- - - - - - - - - - - - - - -

TO MR JELLO:

If you're going to make wild statements that the oceans are lower now than they were, why did you cite an article that effectively states they're higher now than they were - read between the lines.

All that article does is to distort the facts and hide the real evidence, it's written for gullible people.

Wer're talking global waming and global sea level rises, not Tasmanian warming or Tasmanian sea level falls. The seas and oceans do not rise or fall uniformly, they are not all at the same height (the reason there are unequal locks in the Panama Canal even though it connects two oceans). The global average sea level rise is 3mm a year, in some places it's rising 10 times as fast (Sundarman Delta for example), in a few places it's falling.

I mean no offense, but I think your math is wrong and Trevor's is right. I've seen his results from any number of extremely credible sites. Like the US Geological Survey, and the National Science Foundation, not exactly "alarmists".

Since you don't show your calculation, it's impossible to say where you're going wrong.

From your previous posts, I'd say it was a honest mistake.

The first claim is accurate. Actually it's a 23 foot sea level rise.

http://news.nationalgeographic.com/news/2004/04/0408_040408_greenlandicemelt.html

Not very alarmist to underestimate the rise by 3 feet, is it?

The second claim also appears to be correct.

"If all land ice melted, sea level would rise approximately 230 feet (70 meters) worldwide.

Maybe you should check your facts before accusing people of lying, especially when you're accusing a large group of people based on one person's (correct) claims. I'm tempted to ask why global warming deniers just like about global warming acknowledgers, but that would be a (somewhat) unfair generalization.

comrade,

you do not "believe" our facts?

perhaps you need reducation?

of course this can occur. everyone will die.

all the dead bodies wiil make the world look like a bowl of chicken and rice soup if we don't act now.

now,please stop questioning us and "contribute" to the cause before it's too late and we decide to raise the sea level to 300 ft.

thank you.

I know you know the answer. How can you extort large sums of money from the populous without fear? This is the same reason bank robbers use big guns to rob banks. You'll never get enough if you think small.

Actually the ocean levels are lower now than they were over 150 years ago by over one inch.

I wonder how the extremist explain this away?
