Sea ice extent in the Arctic fell to 483,000 square km (186,000 square miles) on August 13, a new record

The Arctic Ocean is feeling hot, hot, hot, says new report released by the U.S. National Snow and Ice Data Center. 
According to the report, sea ice extent in the Arctic dropped to a record low on August 13, and will continue dropping to new record lows by the end of the month. 
Sea ice extent, which measures the amount of sea ice remaining in the ocean, fell to 483,000 square km (186,000 square miles) on August 13. This was a dip from the previous record low on the same date back in 2007. 
But that's not the end of it. The Arctic sea ice is expected to continue melting through mid to late September, but more record lows have been predicted for the end of this month.
"A new daily record would be likely by the end of August," said Ted Scambos, lead scientist at the U.S. National Snow and Ice Data Center. "Chances are it will cross the previous record while we are still in ice retreat."
The news of a new record hasn't surprised many among the environmental community. This may be because the Arctic neared record lows last year, according to climate physics Professor Seymour Laxon from University College London. It almost seemed inevitable that this would happen at some point. "Rapid" melting occurred in June of this year as well with 100,000 square km melting daily.
However, Laxon worries that this rate of melting will adjust the prediction for an ice-free Arctic in summer. Previous reports estimated that the Arctic will have an ice-free summer in 2100 based on melting at that time, but when the 2007 low hit, this estimate was brought to the 2030-2040 range. Scientists are now concerned that this year's lows will bring that date even closer, which is problematic because the melting of sea ice means warming of the oceans. Sea ice keeps the Earth's temperature controlled.  
Global warming always seems to be a hot topic (pun intended). A recent controversial report released by James Hansen at NASA's Goddard Institute for Space Studies claimed that global warming has caused hotter summers since 1980, but many question the merit of his opinions based on his position on climate change.

This is one big worry. Melting ice from Greenland (of which there are millions of tons) has a very strong likelihood of pushing the North Atlantic Current south, preventing the warm waters from entering the area around Canada, Europe, and Greenland. The lack of warm water chills Europe and Canada, throwing both into an ice age.

Conversely, global warming also increases the desertification of America's breadbasket through higher temps, lower rainfall, and drought. The end result is that you can't grow food in the USA due to the destruction of the breadbasket, and you can't grow food in Canada due to the colder temps. The result is the mother of all food shortages. Feel like paying $20 for a loaf of bread? In a few years this could be reality.

Sorry, haven't you all been paying attention, Greenlands ice has all melted a week or so ago. Yea, it was reported by NASA that it almost all melted in 3 days was it.

Remarkably fast melting and it's from some satellite pics about 4 days apart.

Not sure why coastal flooding on a grand scale hasn't happened yet - as predicted would happen!

Well, there is problem with "forecasts/predictions". I live in a part of the American breadbasket.

We had one of the driest/warmest Junes and Julys on record. Which the AGW proponents used as a sign that their predictions were correct.

Yet, August has turned out to be one of the wettest/coolest on record. Funny enough, those AGW proponents have been quiet lately. Hmmm current circumstances don't fit!

We have had climatologists(Fed, state, univeristy) tells us we should expect warm and dry until Oct. Well, August has thrown a wrinkle into that predicition.

They don't know for sure what will happen. Enjoy the ride and do the best to prepare and adapt. Which is nothing new, we have dealt with it in the past and we will surely deal with it in the future.

I'll add that no climatologist worth their salt is going to try to predict the weather or climate. They can only say: Given conditions a, b and c we expect that the climate will be about x around y date. They cannot predict with any accuracy whether they will be true at that date or not.

Predicting weather and climate are fraught with problems since there are so many unknowns past a future date. The systems are so complex that unforeseen events, cause and effect, etc. are not likely to be predicted.

You are correct sir!

I was just bringing up that people(AGW types) are pointing to this summer and saying it fits into the overall predicitions of man-made global warming. Only a part of the summer has fit the story, while the remainder of the summer has refuted that idea.

Also I agree with your statement on climatologists. Too many thou have opened their mouth, to the public.

I find it funny we have problems accurately predicting weather days, weeks or months ahead of time. Yet we are suppose to believe people can predict the climate years, decades from now.

You bet! It seems every time a warm spell comes along, it's all about global warming. When a cold spell comes along no one says anything.

It's the mindset of paying attention to what reinforces a person's beliefs and not challenging them.

That's because it's statistics, not any one day. Statistically, the number, size, and severity of 'extreme weather events' (drought, heatwave, etc) was very, very high this year. It is statistically unlikely that those events would have occurred if the global climate was unchanged from 20 years ago. But again, that's statistically unlikely. Until the statistics pile up for a few more years there is still some question to the numbers but a cold, wet august isn't going to be enough to erase the outlier from the pool.

I find it interesting you use the 20 year mark.

The lack of rain and high heat the first two months of summer. This is the first time since 88 have we had such a hot and dry period in those two months. Just over 20 years ago.

Ahh yes the summer of 88, the same summer Hansen's little dog and pony show before Congress.

Our August, is the wettest and coolest since 93.

So called extremee weather events have happened before and will happen again and again and again....

Didn't something happen in the summer of 69 too?

Yes, yes it did! But then would you know? I don't know you! :)

When I first moved to Florida, we were told that the lack of hurricanes was a sign of AGW. Then we had a year with 4 major hurricanes... and that was a sure sign of AGW.

...the desertification of America's breadbasket through higher temps, lower rainfall, and drought.
All things that have been happening for at least a thousand years or more anyhow, even if we are accelerating it, it is going to happen.

There used to be lakes in allot of the inland desert areas of So Cal 150 years ago that are now just desert, some of them used to have paddle wheel ships to cross them in the gold rush days. This happened long before cars and huge pollution. Why do you think Area 51 was chosen? It had a huge dry lake bed that was ideal for landing planes.
