Northwest Passage opens for the third time in recorded history

The Northwest Passage is now open for business. And, as this satellite image composited by the The University of Illinois Cryosphere Today shows, the Northeast Passage is too. Jeff Masters at WunderBlog reports:

"It is now possible to completely circumnavigate the Arctic Ocean in ice-free waters, and this will probably be the case for at least a month. This year marks the third consecutive year—and the third time in recorded history—that both the Northwest Passage and Northeast Passage have melted free. The Northeast Passage opened for the first time in recorded history in 2005 and the Northwest Passage in 2007.

Solar activity and natural variation from year to year (that doesn't form a long-term trend) could certainly open it up for short periods of time. The problem today is that solar activity is at a minimum yet these things are occurring, and starting to occur consistently.

 

Fucking Discovery Channel. What are they doing to this planet?

 

And this is because of all of that sensitive CO2? But you can't show this in a laboratory because there are too many other variables, amiright?

 

Can't show what? That CO2 is a greenhouse gas that absorbs heat and warms the Earth? There's plenty of proof for that.

 

That's like saying "paper burns so if we stuff enough of it into a rocket we can reach the Moon"

It's really low-brow and unscientific.

No one is disputing that CO2 is a GHG, we're just asking you to show us ONE time in a lab setting how a 200PPM increase does any of the things you say it does.

Democrats controlled Congress during most of this recent warming period so maybe a Dem Congress is responsible for the Arctic Ice melting.

 

This study shows how a doubling of CO2 from 280ppm to 560ppm increases temperature between 1.5 and 6.5 degrees C, with 3 to 3.5 being the most likely. This study has it between 2.5 to 3.5 degrees. This one has it between 2.3 and 4.1 degrees.

 

I had to skim all three just in the very unlikely event that one was an actual laboratory test using only changes in CO2 as the control.
