There is no ice in the Hudson Bay, and this is normal for the time of year.

Every year, Hudson Bay is ice free for 2-3 months, yet the bears who live there survive. Apparently they aren’t as lame as the people who worry about them.
Hudson Bay has a port in Churchill, which is 1300 NM and three days closer to northern Europe than through the great lakes. An ice free bay would help shipping. This year the first ship was July 29th while last year it was on August 16th.
If there are people who believe Hudson Bay is at or past the tipping point I suggest they pay a call to Winnipeg, Manitoba, where the Hudson’s Bay Company Archives are located. There are over 300 years of ice and shipping records, as well as detailed temperature records from the mid-1700s to the mid 1800s taken at trading posts along Hudson and James bay, as well as scores of inland posts—post clerks were required to keep meteorological records. For example, as summarized by David Thompson from his own observations:
