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.

Don't be a douchenozzle. It didn't happen. The CO2 levels were 300ppm which is within historical variation over the past million years or so, although the upward trend was already apparent at that point. Today we're almost at 400PPM.

Wait so your saying the UPWARD TREND was already happening by the EARLY 20th century BEFORE we had cars all over the world and all the CO2 increasing pieces in place today!!???!!
Hmmmmmmmmm.... Not sure you just helped you argument.

Coal produces much more CO2 than oil, and humans have been burning coal for hundreds of years. That accelerated during the 19th century.

First you believe that. We have no actual proof of it.

Second, even with man burning coal, it was FAR more limited. Trying to say a few million people burning coal was just as bad as billions of people burning gas, coal, etc. is just retarded.

Third it did happen. That's how the Northwest Passage was first traversed. At least the first recorded traversal anyway.
