Global Warming A Myth - Sea Ice Sets Record

[pspr]

By James Taylor

Antarctic sea ice set another record this past week, with the most amount of ice ever recorded on day 256 of the calendar year (September 12 of this leap year). Please, nobody tell the mainstream media or they might have to retract some stories and admit they are misrepresenting scientific data.

National Public Radio (NPR) published an article on its website last month claiming, “Ten years ago, a piece of ice the size of Rhode Island disintegrated and melted in the waters off Antarctica. Two other massive ice shelves along the Antarctic Peninsula had suffered similar fates a few years before. The events became poster children for the effects of global warming. … There’s no question that unusually warm air triggered the final demise of these huge chunks of ice.”

NPR failed to mention anywhere in its article that Antarctic sea ice has been growing since satellites first began measuring the ice 33 years ago and the sea ice has been above the 33-year average throughout 2012.

Indeed, none of the mainstream media are covering this important story. A Google News search of the terms Antarctic, sea ice and record turns up not a single article on the Antarctic sea ice record. Amusingly, page after page of Google News results for Antarctic sea ice record show links to news articles breathlessly spreading fear and warning of calamity because Arctic sea ice recently set a 33-year low.

Of course they don't report it. It doesnt fit the narrative.

Distracting from the news that Arctic sea-ice extent reached a record low on Sept.16 is a widely circulating blog article claiming that at the opposite end of the Earth, Antarctic sea ice is more than making up for the losses.

In the post, climate change skeptic and blogger Steven Goddard states that Antarctic sea ice reached its highest level ever recorded for the 256th day of the calendar year on Sept. 12. He reasons that the Southern Hemisphere must be balancing the warming of the Northern Hemisphere by becoming colder (and thus, net global warming is zero).

The National Snow & Ice Data Center (NSIDC), which tracks sea ice using satellite data, explains on its website why Antarctic ice has weathered global warming more robustly than Arctic ice. Goddard dismisses the explanation, concluding instead, "Antarctic and Arctic ice move opposite each other. NSIDC's dissonance about this is astonishing."

Despite its lack of scientific support, Goddard's post has garnered attention around the Web. In a Forbes.com column about the record high Antarctic sea ice, skeptic James Taylor writes, "Please, nobody tell the mainstream media or they might have to retract some stories and admit they are misrepresenting scientific data."

But if anyone had asked an actual scientist, they would have learned that a good year for sea ice in the Antarctic in no way nullifies the precipitous drop in Arctic sea-ice levels year after year — or the mounds of other evidence indicating global warming is really happening.

"Antarctic sea ice hasn't seen these big reductions we've seen in the Arctic. This is not a surprise to us," said climate scientist Mark Serreze, director of the NSIDC. "Some of the skeptics say 'Well, everything is OK because the big changes in the Arctic are essentially balanced by what's happening in the Antarctic.' This is simply not true." [ Former Global Warming Skeptic Makes a 'Total Turnaround' ]

Projections made from climate models all predict that global warming should impact Arctic sea ice first and most intensely, Serreze said. "We have known for many years that as the Earth started to warm up, the effects would be seen first in the Arctic and not the Antarctic. The physical geography of the two hemispheres is very different. Largely as a result of that, they behave very differently."

The Arctic, an ocean surrounded by land, responds much more directly to changes in air and sea-surface temperatures than Antarctica, Serreze explained. The climate of Antarctica, land surrounded by ocean, is governed much more by wind and ocean currents. Some studies indicate climate change has strengthened westerly winds in the Southern Hemisphere, and because wind has a cooling effect, scientists say this partly accounts for the marginal increase in sea ice levels that have been observed in the Antarctic in recent decades.

"Another reason why the sea-ice extent in the Antarctic is remaining fairly high is, interestingly, the ozone hole," Serreze told Life's Little Mysteries. This hole was carved out over time by chlorofluorocarbons, toxic chemicals formerly that were used in air conditioners and solvents before being banned. "The ozone hole affects the circulation of the atmosphere down there. Because of the ozone hole, the stratosphere above Antarctica is quite cold. Ozone in the stratosphere absorbs UV light, and less absorption [by] ozone makes the stratosphere really cold. This cold air propagates down to the surface by influencing the atmospheric circulation in the Antarctic, and that keeps the sea ice extensive."

But these effects are very small, and Antarctic sea-ice levels have increased only marginally. In the coming decades, climate models suggest rising global temperatures will overwhelm the other influences and cause Antarctic sea ice to scale back, too.

The extent of Arctic sea ice at its summertime low point has dropped 40 percent in the past three decades. The idea that a tiny Antarctic ice expansion makes up for this — that heat is merely shifting from the the Southern Hemisphere to the Northern and therefore global warming must not be happening — is "just nonsense," Serreze said.

What chaps my ass is that they can report in such a biased manner and then the government can force me to pay for it.

I don't think Americans should be forced to pay for Democrat propaganda. Those folks over at NPR actually believe their reporting is balanced and unbiased. Its an outrage.

in other words... science has no idea what is going on with the climate...
nor does it have an explanation for why... temperature precedes co2 buildup or dissipation... and it is all just climate modelers guessing their asses off.


sure we could be waming...
sure we or the cows could be contributing... but we really do not know much...
