This is the third year in a row that freeze-up of Western Hudson Bay (WH) ice has come earlier than the average of 16 November documented in the 1980s. Reports by folks on the ground near Churchill confirm polar bears are starting to move onto the sea ice that’s developing along the shore after almost 5 months on land. After five good sea ice seasons in a row for WH polar bears, this repeat of an early freeze-up means a sixth good ice season is now possible for 2019-2020.
When mothers with cubs are out on the ice (see photo above), it’s pretty certain the mass movement from land to sea ice is well underway because these family units are usually the last to leave.
UPDATE 19 November 2019: Polar Bear Alert report for 11-17 Nov (week 20) confirms that freeze-up is underway, bears are heading out on the ice and problem bears held in the ‘jail’ were released 13 November. See below.
