Data from the National Snow and Ice Data Center (NSIDC) has indicated a dramatic increase in sea ice extent in the Arctic regions. The growth over the past year covers an area of 700,000 square kilometers: an amount twice the size the nation of Germany.
With the Arctic melting season over for 2008, ice cover will continue to increase until melting begins anew next spring.
The data is for August 2008 and indicates a total sea ice area of six million square kilometers. Ice extent for the same month in 2007 covered 5.3 million square kilometers, a historic low. Earlier this year, media accounts were rife with predictions that this year would again see a new record. Instead, the Arctic has seen a gain of about thirteen percent.
William Chapman, a researcher with the Arctic Climate Research Center at the University of Illinois, tells DailyTech that this year the Arctic was "definitely colder" than 2007. Chapman also says part of the reason for the large ice loss in 2007 was strong winds from Siberia, which affect both ice formation and drift, forcing ice into warmer waters where it melts.
Earlier predictions were also wrong because researchers thought thinner ice would melt faster in subsequent years. Instead, according to the NSIDC, the new ice had less snow coverage to insulate it from the bitterly cold air, resulting in a faster rate of ice growth.
Most concern has focused on the Arctic regions, rather than Antarctica. Recent research has indicated Antarctica is on a long-term cooling trend, for reasons which remain unclear.
Earlier this year, concerns over global warming led the US to officially list the polar bear a threatened species, over objections from experts who claimed the animal's numbers were increasing.

quote: Following a record rate of ice loss through the month of August, Arctic sea ice extent already stands as the second-lowest on record, further reinforcing conclusions that the Arctic sea ice cover is in a long-term state of decline. With approximately two weeks left in the melt season, the possibility of setting a new record annual minimum in September remains open.

quote: Interannual variability in extent is large: for example, a record minimum in September of 1995 was followed by very high extent the next year. Globally, the annual variation of sea ice area is about 37% of the mean (Gloersen et al. 1999). Because of this, it is difficult to infer long-term trends from short observational records, or to deduce the influence of possible natural oscillations in ice extent. The great variability in ice extent is especially noticeable in maps depicting the frequency of occurrence of sea ice.

quote: A single day's data to show a climate trend is not very useful. Humorously enough, when I used monthly averages in a previous story on temperature trends, many people chose to complain the period was too short, and that without averaging at least a full year or two, the results were meaningless.
quote: To correct one thing, this isn't "one month" of data. The span is one year, the delta is calculated by monthly averages. And it indicates one thing clearly -- that this year was colder than the last, a conclusion borne out by the statement from the UIUC Arctic researcher I interviewed.
quote: No, you're either not reading or not comprehending my replies. I specifically said this data is meaningful only in establishing that this year was colder than the prior (interannual variability) and to debunk previous alarmist reporting.
quote: To correct one thing, this isn't "one month" of data. The span is one year, the delta is calculated by monthly averages.
quote: Taking about one day or one month means the same as temperature in term of climate trend: nothing
quote: And yes, on a full-month basis, the melting season is over. It stops gemerally in the latter half of September, and reverts again to growth.
quote: Honestly, I didn't think data comprehension would be that difficult for most people. Perhaps I was wrong. The data I gave was not for "early August", they were for the entire month . The image you cite (and the one the NSIDC understandably chose to highlight) was data for one single day of that month.
quote: I'm through explaining it them. The first person or two, I thought they were just trolling, but they just really don't get it.
quote: What are you trying to show here, that there is some fluctuation year on year ? I agree, but it's not relevant. Only the trend is relevant. That seems to be going upwards.
quote: Monthly ice melt averages are not 'useless'; indeed the NSIDC calculates and uses them on a regular basis, much more so than 5-day averages. For all climate research, you typically use the longest mean possible for the problem at ha[...]
quote: Monthly data isn't useless obviously, but annual data *is* more relevant. But the notion that a single day's results are somehow more valuable and indicative than an average for an entire month is, of course, severely flawed.
quote: If you want to learn about what to do with monthly averages in terms of trend
quote: #1 There's more ice up there than there was last year.
quote: #2 It's colder up there than it was last year.
quote: Again, even if words are two complicated
quote: Well, I know enough about words to tell the difference between "two" and too".

quote: the excess of CO2 is toxic to other forms of living.

quote: The UN anounced a few years back that the had to decrease the amount of food they sent to Africa because they couldn't afford it anymore
quote: I just think that if so many scientist say there is a problem, there probably is one.
quote: who said anything about 'banning' CO2?
quote: I can't help but wonder if its an "intellectual" and social trend limited to the US or the Western world, and if the trend will fizzle out or gain momentum. If it gains momentum, then they are signaling an era where humans, instead of seeking knowledge and behaving as individuals, live instead only to serve the greater collective, where a Soviet-style central planning committee directs the lives of the masses. The Enlightenment down the drain entirely.
quote: Sea ice extent has fallen below the 2005 minimum, previously the second-lowest extent recorded since the dawn of the satellite era. Will 2008 also break the standing record low, set in 2007? We will know in the next several weeks, when the melt season comes to a close. The bottom line, however, is that the strong negative trend in summertime ice extent characterizing the past decade continues.

"The world's polar bear population is on the increase despite global warming."According to new research," the Scotsman reports, "the numbers of the giant predator have grown by between 15 and 25 per cent over the last decade."We're seeing an increase in bears that's really unprecedented, and in places where we're seeing a decrease in the population it's from hunting, not from climate change," Canadian polar bear expert Mitch Taylor told the Scotsman.The March 9, 2007 London Telegraph confirmed the ongoing polar bear population explosion ( http://www.telegraph.co.uk/news/main.jhtml?xml=/ne... "A survey of the animals' numbers in Canada's eastern Arctic has revealed that they are thriving, not declining," the Telegraph reports."In the Davis Strait area, a 140,000-square kilometre region, the polar bear population has grown from 850 in the mid-1980s to 2,100 today," added the Telegraph.

quote: Martin Jeffries of the U.S. National Science Foundation and University of Alaska Fairbanks said in a statement Tuesday that the summer's ice shelf loss (off of a Canadian island) is equivalent to over three times the area of Manhattan, totaling 82 square miles — losses that have reduced (total) Arctic Ocean ice cover to its second-biggest retreat since satellite measurements began 30 years ago .

It never ceases to amaze me how gullible many people can be, and how they seemingly refuse to even attempt to verify the claims made by people like Michael Asher or Paul Watson.

A “little sacrifice” is nothing like taking the punishment you would have dished out to the worst offenders on yourself.
