Yes, the sea ice recovers in winter, but it has been receding further every summer, so much so that last year the northwest passage was open.

For arctic explorers sure, but not as a trade route.

I'm not saying there won't be benefits of opening the NW Passage. I'm saying the fact that the passage will be open as a trade route, since, well, ever, is indeed evidence that the extent of summer ice is receding.
Thanks for the link, BTW. Great info. Check out July 2008 vs. July 1979.(comment_max_expanded_depth : 55) (comment depth : 8) (recursion depth : 6) (max_comment_reply_depth : 40) (comment_max_render_depth : 55)Reply loading ...

Here is some good reading for those who want to know about sea ice. The sea comes and goes with the seasons... the problem is it is going earlier and is gone longer. This changes a lot of things...animal breeding and migration are affected as well as the ability to forage. For the Inuit if changes how they move about.
This article is about 5 years old.. the problem has escalated since then...

This is an easier read...and includes simulations.
FTA
As of September 8 2008, Environment Canada analysis indicates that sea ice over the Northern Hemisphere is approaching its minimum of approximately 4.9 million sq. km. which is below normal but still about 0.4 million sq. km. above the record low ice cover in 2007. This will probably make this summer’s sea ice cover the second lowest summer ice cover since hemispheric sea ice records have been kept (at least 50 years). Both the North West Passage (via the Canadian Archipelago) and North East Passage (via the East Siberian Sea) are ice free. (Click here to see a comparison with the last 5-years)"

I believe what you said there is incorrect. The satellite data just ushered in new methods of "viewing" the field. Records have been kept for many years. The thickness of the field is not determined through the use of satellite pictures. Yes the passage has been open over the years but not to extent that we have seen lately.
There were several attempts to get through the passage ...some failed others took years...... yes there were successes...such as the st Roche and Ice breakers as well. To compare the passage today to what was is an unfair comparison and leads people to believe that the passage was ice free way back...not so.(comment_max_expanded_depth : 55) (comment depth : 11) (recursion depth : 9) (max_comment_reply_depth : 40) (comment_max_render_depth : 55)Reply loading ...

"While very warm temperatures were also seen in the Arctic in the 1930s, the loss of Arctic sea ice observed in the past 20 years has no precedent in the historical record. For example, the fabled Northwest Passage opened in 2007, an event that has not occurred since at least 1497, and probably for a much longer span of time. Between 1979 (the year satellite imagery of the North Pole first became available) and 2006, Arctic sea ice extent shrunk by about 10% in winter (4% per decade) and 20% in summer (8% per decade). The loss of sea ice, when plotted on a graph (Figure 3), roughly followed a straight line over time. There were a few noisy ups and downs, reflecting colder and warmer years. A trend that approximately follows a straight line is called a "linear" trend. A continued linear summertime 8% per decade loss of sea ice would leave the summertime Arctic Ocean ice-free by 2100. The ocean would still partially freeze in winter, with about 50% of the ocean covered with ice."

The Antarctic continues to embarrass the prognosticators as it exhibits very strong sea ice growth. In fact the ice is growing by significant amounts (a total of 17% since 1979) and in direct defiance of the orders issued by the computer models.
For the month of December both sea ice extent and concentration were up significantly over 1979 (the first year satellite measurements were available for the full year), 17.3% for ice extent & 18.3% for ice concentration.
Granted this is the Antarctic but we're seeing increases in ice at the South Pole. This does not fit into any of your computer models.(comment_max_expanded_depth : 55) (comment depth : 7) (recursion depth : 5) (max_comment_reply_depth : 40) (comment_max_render_depth : 55)Reply loading ...

Area is not necessarily the same as volume. You are providing a one dimensional piece of information. If you can show that the ice volume on the earth has not changed, I think you would be on to something.

Your comment, link, and info is not based in arguing about bears and hunting ground, it is directed at global warming and evidence or lack of evidence supporting it. You opened the door to the expansion of the topic, not me. If the evidence you provided was directed strictly at habitat, then you might have a foundation for this latest comment.
If you want to remove all the global warming comments for your statements and talk strictly about habitat, bears, and hunting grounds, then you might have a stronger argument.
I am not arguing the bear info, I am not arguing the cause of GW, I am disputing the research and it's one-dimensional point of view concerning GW.(comment_max_expanded_depth : 55) (comment depth : 6) (recursion depth : 4) (max_comment_reply_depth : 40) (comment_max_render_depth : 55)Reply loading ...

Again, how can seeing one frame of a movie inform you as to the contents, direction, plot, and outcome of the movie?
If next year the temp goes up the same amount, would that convince you that global warming is valid and of concern? Last year was a warm year where I am. Does that *wipe out* the other statistics for that year?
One year doesn't make a trend or indicate anything other than it was one cold year.
Ironically, it could be considered a valid hypothesis worthy of study. Did the reduction in many areas of the use of fossil fuels contribute to the change? Are we, and have we, been in a global cool down that has been masked by other factors? I know you intended the question to be more of a comic response, but I think there certainly could be a ounce of truth within.(comment_max_expanded_depth : 55) (comment depth : 8) (recursion depth : 6) (max_comment_reply_depth : 40) (comment_max_render_depth : 55)Reply loading ...

That's well and good. My point is that your application of the information you present is flawed and cannot be used to either support or deny the existence of global warming/ cooling or anything else. It is a very small slice of a very large picture.

The enthusiasts on both sides of any debate are interested in their position and the power it brings. At one time, such things as unions, political action groups, and possibly even lobbyists, all performed needed functions to promote change. Now, they are only there to further their own agenda. Unfortunately, our political system has been optimized for justify their existence. The dems and the reps both have their hand in this and it supports their existence. Neither truly want the system to change because that would change the power balance that they enjoy.
This reminds me of studies that the government and industry supports. One example is the egg debate. One study suggests that *eggs* are bad. This really fuels only one thing, for a study to support that *eggs* are good. The government or an industry group are not really going to fund another study or research that supports the first study, but someone (or the government) will fund research or a study that disputes the first studies findings. Stick almost any topic or commodity between the *'s.
The real problem in my mind with areas like the ANWR is that the industry signed off on it to get the Prudhoe Bay field. They signed a contract and should be forced to abide by their decision, as short-sighted as it may have been.
I'm not against drilling even in ANWR. I am against giving the resource away to a company who will make billions on it. The oil is the commodity of the national government, at this point. I say hire a drilling company to go in and get the oil. Or make the US a partner in the resource, allowing a company to come in and get it and as a partner, the US shares equally in the profits. If the field brings in $1 billion in gross profits, the US gets $500 million.(comment_max_expanded_depth : 55) (comment depth : 12) (recursion depth : 10) (max_comment_reply_depth : 40) (comment_max_render_depth : 55)Reply loading ...

"Twelve-month long drop in world temperatures wipes out a century of warming"
This has to do with the Hadley Center study that show a 12-month drop in temperature ANOMALIES, not the temperatures themselves! This blogger hasn't a clue!
If you want the official position of the Hadley Center, go here:
http://www.metoffice.gov.uk/research/hadleycentre/...
"Anyone who thinks global warming has stopped has their head in the sand."
NASA, GISS, UAH, and RSS all have similar statements.(comment_max_expanded_depth : 55) (comment depth : 8) (recursion depth : 6) (max_comment_reply_depth : 40) (comment_max_render_depth : 55)Reply loading ...

Numbers can be made to say many things. Actually, made to say anything might be a better statement.

You must remember, they're not dealing with real science. Evidence and proof rarely comes into play when dealing with the church of Global Warming, now known as Global Climate Change.

Then how come all the deniers can post is misinterpreted data posted on someone's blog?
It's about time the deniers pony up and produce their data either that A) global warming isn't happening, or B) that it is primarily caused by a factor other than the burning of fossil fuels. Actually, I'd be happy if they just picked ONE of those two opposition stances, they seem to switch between them as necessary.(comment_max_expanded_depth : 55) (comment depth : 7) (recursion depth : 5) (max_comment_reply_depth : 40) (comment_max_render_depth : 55)Reply loading ...
