And when a big hunk of it shears off, as it inevitably will, they'll claim that that is globull warming too. These whackadoodles can't be reasoned with.

[Wuli]

Those crazy authors. How dare they use actual data and facts and not self-serving, jerrrymandered “computer models”. Just wait until the IRS and ABC/CBS/CNN/MSNBC/NBC/NPR/NLSlimes find out, someone will have to investigate the authors. /sarc

[PoloSec]

These are the facts of the underclass, how dare they challenge the King, the facts of King Zero are immutable.

Off with their heads!

I hope some FReeper who knows how will send this article to Eric Bolling and Bob Beckel (co-hosts on The Five on FNC).

Beckel is constantly pushing the global warming mantra and Eric is just the opposite.

An obscure but very interesting and important fact mentioned was the increased albedo effect from the larger ice in the Antarctic. Albedo, or reflective loss of solar radiation (by the ice) effectively cools the earth as the heat energy that would have been absorbed by open water is not absorbed to the same extent by ice, and is reflected into the atmosphere and into space. The loss of solar energy by albedo is limited by the insulating effect of the atmosphere, but the overall loss would be greater than the gain. net effect=cooling

“Global warming” is so yesterday! Get with the program! It’s “Climate Disruption” now!

The loss of solar energy by albedo is limited by the insulating effect of the atmosphere, but the overall loss would be greater than the gain. net effect=cooling

Albedo works “against” the “We are melting all of the Arctic sea ice and will perish” syndrome so often propagandized.

First, ALL of the Arctic sea ice expends (freezes) and contracts (melts out again) like a “beanie cap” roughly centered on the north pole. Working out the arithmetic and geometry, you can pretty accurately summarize that “Arctic sea is at its maximum at latitude 71 north each year in early April, and is at its minimum at latitude 79-80 north each fall in mid-September.)

So it cycles between 71 north and 80 north.

Antarctic sea ice also expands and contracts: But much, much closer to the equator (at a LOWER altitude). Antarctic sea ice is at its minimum in late February at latitude 66 south, and expands until it reaches its maximum in mid-September at latitude 59-60 south!

Because the Antarctic sea is is closer tot he equator at all times of the year, it reflects much more sunlight than the Arctic sea ice does on an annual total basis. You have to play some mathematics to account for the changing solar output each day, the changing solar elevation angles, the changing tilt of the earth, the changing ice edge extents, etc ... but the Antarctic sea ice controls how much sunlight is reflected back into space 7 months of the year (September-March), and the smaller arctic sea ice only 5 months of the year (April-May-June-July-August).

Also, the Arctic sea ice tends to be 50% multi-year ice, so its gets dirtier and dust-covered. This reduces its albedo significantly during the summer: going from a clean & pristine 0.93 albedo to as low as 0.45 in June and July.

The Antarctic sea ice almost completely melts each Antarctic summer. So, each antarctic winter, spring and fall it is a fresh surface often covered with fresh snow and no industrial or “desert” dust. (No land area in the south, just the ice-covered high plateaus of Antarctica itself.)

So, any “excess” antarctic sea ice edge in September reflects over 5 times the energy that the same area of arctic sea ice would.

The Sea Ice growth at Antarctica is quite amazing

It's 25% above normal right now and not only is it a record high, it's about 10% higher than the previous record (2009)!!!!

See, http://arctic.atmos.uiuc.edu/cryosphere/antarctic.sea.ice.interactive.html for a comparison of previous years. This year is in yellow and look how far it's above the previous years.

Good display.

See? It proves there’s “Climate Disruption”...

now about that carbon tax.

The excess Antarctic ice is just as much evidence of global warming as the missing Arctic ice, silly.

Yep, the Fraudsters excuse is that the melting ice from the land at Antarctica is lowing the salinity in the seas around Antarctica, thus raising the freezing point of the water which is causing more ice to form

Of course the go silent when you confront them by asking if melting land ice is causing the record sea ice, then how come they same isn’t happening in the Arctic? We are always hearing about how Greenland & Alaska Glaciers are melting aren’t we? So shouldn’t there be record sea ice around them and the Arctic as a whole?

Nope, no answer. I guess to the Fraudsters Physics work differently depending on which Hemisphere you are in, remember the Fraudsters are the same people who think Heat from Global Warming can sink below cold and “hide” in the deep ocean

Also, from 2000 – 2007 Antarctica was losing sea ice. This prompted the 2007 IPCC report to predict that Antarctic sea ice would continue to decline and maybe soon accelerate to match the Arctic and the poor penguins were going to die. Of course, right on queue, the Antarctic reverse itself and continues to hit record highs

So if Global Warming is causing increase in sea ice now, what caused the decrease in 2000 – 2007? They can't answer that either.

All true, snow cover in North America and Eurasia performs a similar function in the Northern Hemisphere as sea ice does in the S.H. I see on cryoshere that there is still a great deal of snow on the ground at higher latitudes in the N.H. So planet wide cooling would not be surprising.

One thing that you posted on at WUWT that I found very interesting was that open Arctic waters where in fact a heat/energy loss for the planet most of the year. More energy begin radiated into space then absorbed by sunlight from a low inclined Sun. I tried to find some numbers on this but was unable to. I think you are correct on this.
