Volume of water necessary to raise sea-level 20-feet: ~6 x 1024m3

I don't understand where that number comes from, or does it mean anything?

Will the Ice Caps Melt?

Not until the earth heats up hotter than it has in millions of years.

Yeah. I think it should be 2.11 X 10^15 cu meters. Six meters times area of sea.

All I will say, as a former Mechanical Engineering student with Engineering-level Physics coursework in my not-too-recent past is...

Dang, there are some smart people that contribute to this forum.

But then again, I’ve forgotten more physics then all you guys know.

(That’s because I’ve essentially forgotten it all, and you just can’t say you know it all!)

It's the difference in cubic meters between the current sea surface level and one that is 20 feet higher.

As far as I can tell both the exponent and the coefficient are meaningless. But notice that he also got the next number wrong. It should be 22 x 10^14 or 2.2 x 10^15, not 22 x 10^15.

Since the guy doesn't even understand exponential notation correctly, my judgment is that it is not worth proceeding further.

hundreds of times more heat energy must be imparted into the ice-caps to melt sufficient ice to raise sea-levels the catastrophic levels prophesied by Al Gore.

This is entirely consistent with Al Gore's gross exaggeration of facts to advance his agenda.

After Live Earth he repeatedly claimed that two billion people participated worldwide - internet stats and TV ratings actually showed a worldwide audience of around 40 million - just TWO PERCENT of his claimed total...

The man is a blatant and repetitive LIAR..

I agree. The volume of water should approximate the volume of ice.

"The engineer has learned vastly more from the steam-engine than the steam-engine will ever learn from the engineer."

-- Prof John B. Fenn, Nobel Prize, Chemistry, 2002

As well as the numerical and conceptual errors noted, I think this quote is a botch. It's certainly "off" since the steam-engine is not capable of learning, and would stand for steam-engineering as a metonym, but in that case it contradicts itself.

I knew this as "Science owes more to the steam engine than the steam engine owes to science" and a google search of "science owes more to the steam engine" gets 300+ hits, where "The engineer has learned vastly more from the steam-engine" hits only this putative citation.

The familiar quote means that the practice of steam engineering contributed more to the knowledge of thermodynamics than vice versa.

This looks like a good article. Mark for later read.

Thanks for posting it.

Will the Ice Caps Melt?

Um, no. We're talking about an area on the planet where there's a significant heat loss for a good chunk of the year with no appreciable heat inflow.

Warm air is not dense enough to have a significant impact on bringing in heat, nor is there enough mixing of the atmosphere between the temperate and polar regions.

The ocean currents encircle Antarctica no appreciably warmer water is being brought in, like the Gulf Stream or the Japan Current are doing to the Arctic.

Net heat loss over the period between the equinoxes is pretty large.

Warmer air is capable of holding more moisture than colder air, so the closer the temperature is to freezing, the more likely snowfall is to increase. So the little snowfall that the Antarctic gets now that just never melts will be replaced by much greater amounts of snowfall that may melt some, but the net result could be an increase in the polar ice cap if snow and ice accretion is greater than the melting that is occurring.

For the caps to really make any progress in melting, there would need to be a much larger inflow of heat than there is now with temperatures enough above freezing for long enough periods of time to make a difference.

For a part of the planet that spends most of the winter in total darkness, and has weak insolation during the summer, this is going to be somewhat problematic.

If Iceland melts. Will they then just call it Land or landland?

I read an article, recently, that said that ancient volcanoes under the ice in Antarctica had been venting steam, and melting the ice, enough that they had been able to see the affects through the ice for the first time.

Jerome J. Schmitt has a degree in mechanical engineering from Yale, and is president of NanoEngineering Corporation.

Bill Nye the Science Guy is an ME too.

He demonstrated his lack of reasoning skills on Larry King the other day.
