After a 2007 polar meltdown that sparked global concern, experts say the stage is set for another record-setting retreat of Arctic Ocean ice - with a top Canadian climate scientist already bracing for the once-unthinkable: open water at the North Pole.
"The North Pole may be free of ice for the first time in history," University of Manitoba polar specialist David Barber told Canwest News Service on Monday.

What happened to Superman’s home here on Earth?
Lex should be proud.
I patrolled on USS Billfish
I didn't even mention the Viking Journals of Erik the Red and Green Land.
It amazes me that these eggheads forget what we were taught in 4th grade about the climate record
Mr PHD would have is believe that the earth is static, when all science shows us that it has always been dynamic.
Long before man roamed the planet.
B***S**T. I don’t believe it.
But let’s assume for a second it’s true.
I thought New York City (and other coastal cities) would be under water should the ice ever melt.
I thought deserts would expand everywhere.
I thought that there would be “super hurricanes” destroying the coastlines.
I thought there would be massive droughts - instead the midwest is underwater.
Where are all of these things?
Thanks, meanwhile the South Pole is at record levels since they began keeping records in 1979. The MSM ignores this fact: http://arctic.atmos.uiuc.edu/cryosphere/IMAGES/current.anom.south.jpg

Notice that total global ice coverage is about average since 1979, again no mention by MSM:

Do an experiment... Add ice to a glass and add water to the rim. The ice should float a tad above the rim because it expands and the buoyancy changes.
However, the displacement remains the same. the water level will NOT rise. water is water.
Only if “history” is 28 years long.
Before 1980, before satellite data, we have only anecdotal evidence about North Pole ice.
The “Northwest Passage” (which is not quite the same thing as an “ice free” North Pole, but close) was navigated at least once in the 1890’s, and once more in the 1910’s, using the ships of that era.
At least one attempt in 2006, and one more attempt in 2007, using the latest ships and technology, failed to navigate the Passage.
And, as usual, no mention that ice has been steadily growing in the Antarctic for at least a decade.
Ah, nothing like a little liberal over-hyped hyperbole to help ones evening entertainment.
Pure hyperbole.
As certain as I am that Catastophic Anthropogenic Global Warming(TM) is a complete fraud, your exposition of Archimedes' Principle is pointless. It is ice on land (Greenland and Antartica) whose melting would raise sea-levels. Also, in theory, as the oceans heat up, they expand in volume.
Recent massive volcanoes have risen from the ocean floor deep under the Arctic ice cap, spewing plumes of fragmented magma into the sea, scientists who filmed the aftermath reported Wednesday.
The eruptions -- as big as the one that buried Pompei -- took place in 1999 along the Gakkel Ridge, an underwater mountain chain snaking 1,800 kilometres (1,100 miles) from the northern tip of Greenland to Siberia.
Scientists suspected even at the time that a simultaneous series of earthquakes were linked to these volcanic spasms.
But when a team led of scientists led by Robert Sohn of the Woods Hole Oceanographic Institution in Massachusetts finally got a first-ever glimpse of the ocean floor 4,000 meters (13,000 feet) beneath the Arctic pack ice, they were astonished.
What they saw was unmistakable evidence of explosive eruptions rather than the gradual secretion of lava bubbling up from Earth's mantle onto the ocean floor.
EARTH'S HEAT ADDS TO CLIMATE CHANGE TO MELT GREENLAND ICE
COLUMBUS , Ohio -- Scientists have discovered what they think may be another reason why Greenland 's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice.
They have found at least one “hotspot” in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered.
The researchers don't yet know how warm the hotspot is. But if it is warm enough to melt the ice above it even a little, it could be lubricating the base of the ice sheet and enabling the ice to slide more rapidly out to sea.
Here’s a quick trick to silence your global warming friends. Fill a glass with ice cubes. Then fill it to the brim with water. When you start the example ask them how much water will spill out onto the table as the ice melts. The answer is none. Water expands as it freezes, contracts as it melts. Melting polar ice will not cause flooding.
To what extent have scientists measured changes in the distance between the center of the earth and various parts of the crust? I would think such things could have a significant effect upon apparent sea level.
True enough. But the major point remains the same. The earth is not static
Geothermal? in Iceland?/Greenland?
Nooo... way! ;)
ABSTRACT:
"Carbon dioxide in the atmosphere is the product of oceanic respiration due to the well-known but under-appreciated solubility pump. Carbon dioxide rises out of warm ocean waters where it is added to the atmosphere. There it is mixed with residual and accidental CO2, and circulated, to be absorbed into the sink of the cold ocean waters. Next the thermohaline circulation carries the CO2-rich sea water deep into the ocean. A millennium later it appears at the surface in warm waters, saturated by lower pressure and higher temperature, to be exhausted back into the atmosphere. Throughout the past 420 millennia, comprising four interglacial periods, the Vostok record of atmospheric carbon dioxide concentration is imprinted with, and fully characterized by, the physics of the solubility of CO2 in water, along with the lag in the deep ocean circulation.
Notwithstanding that carbon dioxide is a greenhouse gas, atmospheric carbon dioxide has neither caused nor amplified global temperature increases. Increased carbon dioxide has been an effect of global warming, not a cause. Technically, carbon dioxide is a lagging proxy for ocean temperatures. When global temperature, and along with it, ocean temperature rises, the physics of solubility causes atmospheric CO2 to increase.
If increases in carbon dioxide, or any other greenhouse gas, could have in turn raised global temperatures, the positive feedback would have been catastrophic. While the conditions for such a catastrophe were present in the Vostok record from natural causes, the runaway event did not occur. Carbon dioxide does not accumulate in the atmosphere."

The graph above represents temperature and CO2 levels over the past 400,000 years. It is the same exact data Al Gore and the rest of the man-made global warmers refer to. The blue line is temps, the red CO2 levels. The deep valleys represent 4 separate glaciation periods. Now look very carefully at this relationship between temps and CO2 levels and keep in mind that Gore claims this data is the 'proof' that CO2 has warmed the earth in the past. But does the graph indeed show this? Nope. In fact, rising CO2 levels all throughout this 400,000 year period actually lagged behind temperature increases ...by an average of 800 years! So it couldn't have been CO2 that got Earth out of these past glaciations. Yet Gore dishonestly and continually claims otherwise. Furthermore, the subsequent CO2 level increases never did lead to additional warming, the so-called "runaway greenhouse effect" that Al Gore and his friends keep warning us about. -ETL

"The above chart shows the range of global temperature through the last 500 million years. There is no statistical correlation between the level of carbon dioxide in the atmosphere through the last 500 million years and the temperature record in this interval. In fact, one of the highest levels of carbon dioxide concentration occurred during a major ice age that occurred about 450 million years ago [Myr]. Carbon dioxide concentrations at that time were about 15 times higher than at present." [also see 180 million years ago, same thing happened]:

So, greenhouse [effect] is all about carbon dioxide, right?
Wrong. The most important players on the greenhouse stage are water vapor and clouds. Carbon dioxide has been increased to about 0.038% of the atmosphere (possibly from about 0.028% pre-Industrial Revolution) while water in its various forms ranges from 0% to 4% of the atmosphere and its properties vary by what form it is in and even at what altitude it is found in the atmosphere.
In simple terms the bulk of Earth's greenhouse effect is due to water vapor by virtue of its abundance. Water accounts for about 90% of the Earth's greenhouse effect -- perhaps 70% is due to water vapor and about 20% due to clouds (mostly water droplets), some estimates put water as high as 95% of Earth's total tropospheric greenhouse effect (e.g., Freidenreich and Ramaswamy, 'Solar Radiation Absorption by Carbon Dioxide, Overlap with Water, and a Parameterization for General Circulation Models,' Journal of Geophysical Research 98 (1993):7255-7264).
The remaining portion comes from carbon dioxide, nitrous oxide, methane, ozone and miscellaneous other 'minor greenhouse gases.' As an example of the relative importance of water it should be noted that changes in the relative humidity on the order of 1.3-4% are equivalent to the effect of doubling CO2.

Water Vapor Rules the Greenhouse System
Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect (4). Interestingly, many 'facts and figures' regarding global warming completely ignore the powerful effects of water vapor in the greenhouse system, carelessly (perhaps, deliberately) overstating human impacts as much as 20-fold.
Water vapor is 99.999% of natural origin. Other atmospheric greenhouse gases, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and miscellaneous other gases (CFC's, etc.), are also mostly of natural origin (except for the latter, which is mostly anthropogenic).
Human activities contribute slightly to greenhouse gas concentrations through farming, manufacturing, power generation, and transportation. However, these emissions are so dwarfed in comparison to emissions from natural sources we can do nothing about, that even the most costly efforts to limit human emissions would have a very small-- perhaps undetectable-- effect on global climate.
