Arctic ice thins dramatically

[westwall]

As one can see from the graph, we started, in 1979, with a winter area of 15 million kilometers, and a summer area of 5.5 million kilometers. This years winter high was 13 million kilometers, and the last four years lows have been from 3 to 3.5 million kilometers. That is about a 50% reduction for the summer low.

For the volume, the reduction is even more significant.

At lunch today, the local news said we have had 24 days of 90 degree or wamer weather. The record is 44 days and tomorrow is suppose to be a high of 88. The year it was 44 days in a row was 1988.

The rate of Arctic Ocean sea ice decline continued during the first half of July on a pace as rapid as any year since satellite data began to be collected in 1979, the National Snow and Ice Data Center said this week.

"Arctic sea ice extent declined at a rapid pace through the first half of July, and is now tracking below the year 2007, which saw the record minimum September extent," the agency, based at the University of Colorado, reported.

"The rapid decline in the past few weeks is related to persistent above-average temperatures and an early start to melt. Snow cover over Northern Eurasia was especially low in May and June, continuing the pattern seen in April."

The snow and ice data center said that for the years before 1979, there is not as comprehensive a record for the rate of melting as that obtained by satellite, but "shipping records and other evidence show that the ice extent has been in a continued state of decline for at least the last hundred years. Climate models predicted that Arctic sea ice loss would accompany warming temperatures in the Arctic. But the ice loss has happened faster than any models predicted, and researchers now expect that the Arctic Ocean will be ice-free in summer well before the end of the century."

This year, the overall ice decline was 46,000 square miles a day during the first two weeks of July, the report said.

As of July 17, ice covered 2.92 million square miles of the Arctic, which was 2.24 million square miles below the 1979-2000 average.

We've still not had a day over 100 degrees yet. I have no idea how many years it's been since that occured but the old timers around here can't remember one. I actually went snowshoeing today!

Hell, Portland Oregon hasn't had a single freaking 90f degree day yet. Only a hand full of 80f and the rest being 60s and 70s all the way through July. I mean wtf?

The Canadian Ice Service Digital Archive (CISDA) is a compilation of weekly ice charts covering Canadian waters from the early 1960s to present. The main sources of uncertainty in the database are reviewed and the data are validated for use in climate studies before trends and variability in summer averaged sea ice cover are investigated. These data revealed that between 1968 and 2008, summer sea ice cover has decreased by 11.3% ± 2.6% decade−1 in Hudson Bay, 2.9% ± 1.2% decade−1 in the Canadian Arctic Archipelago (CAA), 8.9% ± 3.1% decade−1 in Baffin Bay, and 5.2% ± 2.4% decade−1 in the Beaufort Sea with no significant reductions in multiyear ice. Reductions in sea ice cover are linked to increases in early summer surface air temperature (SAT); significant increases in SAT were observed in every season and they are consistently greater than the pan-Arctic change by up to ∼0.2°C decade−1. Within the CAA and Baffin Bay, the El Niño-Southern Oscillation index correlates well with multiyear ice coverage (positive) and first-year ice coverage (negative) suggesting that El Niño episodes precede summers with more multiyear ice and less first-year ice. Extending the trend calculations back to 1960 along the major shipping routes revealed significant decreases in summer sea ice coverage ranging between 11% and 15% decade−1 along the route through Hudson Bay and 6% and 10% decade−1 along the southern route of the Northwest Passage, the latter is linked to increases in SAT. Between 1960 and 2008, no significant trends were found along the northern western Parry Channel route of the Northwest Passage

If it weren't for the claims of doom climate science would be an obscure academic niche. Global warming has made everyone in the field rich in at the very least academic bullshit (I'm a famous scientist which makes me very important!) and some in wealth of dollars. Some people understand that the alarmist scientists are as corrupt as trial lawyers and unions and more are beginning to understand that fact.

Hilarious how you denier cult dingbats repeat the same myths no matter how many times they are debunked. I've already gone through this with the walleyedretard some pages back on this thread. To reiterate...

Walleyedretard, your whole "submarines in open water at the pole in the 60's" argument is once again based entirely on your bottomless ignorance and gullibility. Spots of open water in the mostly ice covered Arctic ocean have always been a common occurrence in the summer months as the winds move and shift the ice. The difference now is that the extent and thickness of the ice are greatly diminished.

Arctic Ice Cap
(excerpts)

According to University of Washington oceanographer Dr. Drew Rothrock and other scientists who study the Arctic, open water at the pole is a common occurrence.

ROTHROCK: "There's a lot of open water, a lot of cracks of this size they describe in the sea ice in the summer."

In fact, at any given time during the summer, 10 to 15 percent of the Arctic Ocean is not covered by ice, says Dr. Mark Johnson, a physical oceanographer at the University of Alaska Fairbanks. Johnson spends a great deal of time modeling the ever-changing dynamics of the ice cap. He says the six-mile-long opening in the ice—called a lead—that tourists saw, sounds about right for this time of year.

The reason there is open water at the North Pole is because the ice cap is not, as some people might think, a stable, unchanging sheet of ice. Far from it, says Rothrock.

ROTHROCK: "It's a big ocean up there at the North Pole. It has floating sea ice covering it, which is typically about ten feet thick. It's not like an ice sheet or glacier on land, which is the situation at the South Pole. Sea ice is pretty mobile stuff. It moves around. It cracks. It breaks. It piles up. It's always on the go."

...That seems to fit with records from about 1930 to 1960 that show sea ice in the high Arctic was thick and widespread. It also seems to mesh with data from 1960 to 1990, which shows that sea ice became 40 percent thinner overall, according to Rothrock's research.

ROTHROCK: "We've published results from submarine cruises, where they have upward-looking sonar and they are able to determine ice thickness. We took data taken from cruises in the 1990s that we had been party to and compared it to older data from the '50s, '60s and '70s and found quite a large difference."

[RollingThunder]

Arctic sea ice loss due to global warming is very bad and getting worse. In the last half century or so, the Arctic has lost millions of square kilometers of sea ice, perhaps as much as 50% of the previous long term average area of coverage. There was a record minimum of ice set in 2005 and then an even lower record low extent in 2007, down another 23% under the 2005 record low. This year is on track to match or exceed that record ice loss set in 2007. The shiny, white sea ice reflects about 90% of the sun's energy back out towards space but when the ice melts, the dark ocean waters absorb about 90% of the sun's energy, warming the waters and melting more ice in a positive feedback loop. Climate scientists are finding out that the disruption of the Arctic climate patterns and the much higher temperatures there are having major effects on the whole Northern Hemisphere climate.

Summer Arctic Sea Ice Decline

This figure compares the extent of the summer arctic sea ice in 1979 with the extent of the sea ice in summer 2005. Since 1979, more than 20% of the Polar Ice Cap has melted away in response to increased surface air and ocean temperatures.

That was just the ice loss through September 2005. On September 21, 2005, the five-day running mean sea ice extent dropped to 5.32 million square kilometers (2.05 million square miles), the lowest extent ever observed during the satellite record. Since then, much more of the Arctic sea ice has melted in the heat. In 2007 the sea ice cover was diminished another 23% from the previous low in 2005, down to only 4.28 million square kilometers (1.65 million square miles). Now 2011 is on track to match or beat the 2007 record low sea ice cover.

"Arctic sea ice during the 2007 melt season plummeted to the lowest levels since satellite measurements began in 1979. The average sea ice extent for the month of September was 4.28 million square kilometers (1.65 million square miles), the lowest September on record, shattering the previous record for the month, set in 2005, by 23 percent (see Figure 1). At the end of the melt season, September 2007 sea ice was 39 percent below the long-term average from 1979 to 2000 (see Figure 2). If ship and aircraft records from before the satellite era are taken into account, sea ice may have fallen by as much as 50 percent from the 1950s."

The largest species invasion in over 2 million years is now underway as Arctic ice cover melts and shrinks, permitting a freer exchange of species between the Pacific and Atlantic Oceans; dire and dramatic consequences for Atlantic biodiversity are predicted.

From microscopic plants and jellyfish to predatory packs of Orcas and soon-to-be-arriving squid...The "alien" invasion of the Atlantic ocean by Pacific Ocean species is fully underway, all made possible by ever-decreasing Arctic sea ice cover.

It is now accepted that oceanic and atmospheric warming is causing the Arctic ice sheet to steadily shrink, accelerated by loss of ice albedo (reflectivity of light off ice); Arctic ice cover has become so fragmented and sparse in some areas that, for the first time in centuries, an "ice-free" Northwest Passage was possible during winter. This summer's ice-cover is at it smallest extent in centuries, if not millennia.
