As a result, the Pole may be completely ice-free at the surface and composed of nothing but open water by September. As reported in September of last year, the Northwest Passage was ice-free for the first time known to man. The implications of this, as well as the causes, are still being debated. Are global warming experts just short-sighted alarmists? Are we heading for a global ice age? Or is the increase in global mean temperature having an effect on our planet?"

Science: Impassable Northwest Passage Open For First Time In History 528 comments
An anonymous reader writes "The Northwest Passage, a normally ice-locked shortcut between Europe and Asia, is now passable for the first time in recorded history reports the European Space Agency. Leif Toudal Pedersen from the Danish National Space Centre said in the article: 'We have seen the ice-covered area drop to just around 3 million sq km which is about 1 million sq km less than the previous minima of 2005 and 2006. There has been a reduction of the ice cover over the last 10 years of about 100 000 sq km per year on average, so a drop of 1 million sq km in just one year is extreme.'"

Arctic Ice Extent Understated Because of "Sensor Drift" 823 comments
dtjohnson writes "The National Snow and Ice Data
Center (NSIDC) has been at the forefront of predicting doom in the arctic as ice melts due to global warming. In May, 2008 they went so far as to predict that the North Pole would be ice-free during
the 2008 'melt season,' leading to a lively Slashdot discussion. Today, however, they say that they have been the victims of 'sensor drift' that led
to an underestimation of Arctic ice extent by as much as 500,000 square
kilometers. The problem was discovered after they received
emails from puzzled readers, asking why obviously sea-ice-covered
regions were showing up as ice-free, open ocean. It turns
out that the NSIDC relies on an older, less-reliable method of tracking
sea ice extent called SSM/I that does not agree with a newer method called AMSR-E. So why doesn't NSIDC use the newer AMSR-E data? 'We do not use AMSR-E data in our analysis because it
is not consistent with our historical data.' Turns out that the AMSR-E data only goes back to 2002, which is probably not long enough for the NSIDC to make sweeping conclusions about melting. The AMSR-E data is updated daily and is available to the public. Thus far, sea ice
extent in 2009 is tracking ahead of 2005, 2006, 2007, and 2008, so
the predictions of an ice-free north pole might be premature."

It's the sound of that joke going way over your head.
Your remark interests me cause as a relative new slashdot member, I noticed that one of the main things I love about the threads here is the wonderful intermixing between jokes, facts, irony, wisdom and sarcasm.
Your reasonably funny joke, gave someone else the opportunity to spread a fact he's been sitting on for years. Besides all the funny guys, there are a lot of smart people dwelling here, and I for one welcome the knowledge especially in this intermixed way.
In other words. Take it easy..

This is not news. This is a prediction that there might be news in September.
If it doesn't happen, will we get an apology for misleading us?

"The melt would be mostly symbolic--thicker ice, pushed against the Canadian continental shelf by weather and Earth's rotation, would still survive the summer."
So when we say the North Pole will melt we are talking about a point not the whole Artic ocean which is what impression one might get from the title.
Re:From TFA (Score:5, Informative)
That's correct. The last estimate (2006) for a complete summer Arctic melt was the year 2013.
Before that it was 2038, and before that it was the year 2100...

Yes. No one credible believes that we are entirely responsible for the climate change, on the other hand no one credible disputes that we are contributing to it. No matter what the cause, the increased global temperature is a bad thing for us and thus it is in our best interest to stop contributing to the change ASAP.
