I'm still waiting for the proof that the Northwest Passage was warmer than now.
I would think that even a jester would be able to figure it out.
If a wooden ship was able to navigate the Northwest Passage over a hundred years ago, but ships can't do it today, wouldn't that mean it was warmer back then?
Before you start with your "it took three years baloney", the Northwest Passage was navigated in one season in 1944 by the St. Roch.
Before you run to scepticalscience.com about the St. Roch
HERE, please note that the article in scepticalscience.com is from 2011. Therefore their claims about the Northwest Passage being ice free "today" are no longer true, not to mention how they try to downplay what the St. Roch accomplished in 1944.
However, your scepticalscience.com has no answer for the Gjoa navigating the Northwest Passage in 1903-1906.
So far, you have yet to give a valid response for how the Gjoa was able to make the voyage.
