Lets just take one of your facts at a time Jon.
The snow caps have reduced 40% in the last 80 years, the process is accelerating.
Which snowcaps (what is a snowcap anyway?) and where and what scientific evidence can you cite that global warming is the underlying cause for this revelation?
By the way...the people that tried the NW passage this year got stuck. Seems like they were a bit optimistic...just like the guys who were gonna paddle to the north pole in their kayaks.
At the moment the Arctic sea ice is very close to it's long term average and about a million square kilometers bigger than last year at this time, the polar bears are just fine and if you plan to circumnavigate that way, I'd suggest an ice boat rather than something with a keel.
In case you would like some proof. Here it is from the U of Illinois Cryosphere center
