re: I did. More carefully.
A graph of arctic regional temperature:

Or another graph
For last few decades it appears that in the arctic the average temperature has increased by around .1 C per decade.
And around the 1930s there was also another warming period- and btw at the time in was also in the news.
And since the end of the Little Ice Age average global temperature has risen.
But at this point in time it doesn't look good if you were planning to travel thru the NW passage this summer.
