Sea ice experts at the\u00a0US National Snow and Ice Data Center<\/a>\u00a0just confirmed my suspicion that the huge area of open water in eastern Hudson Bay during May this year was caused by winds, not ice melt. In other words, it\u2019s a rare occurrence but not a sign of extra-early sea ice melt caused by global warming.<\/p>\n\n\n\n

The graph below is from the same report, showing the \u201cunprecedented\u201d (since 1979 only) nature of this wind-driven event:<\/p>\n\n\n\n

The Canadian Ice Service shows this in regional context for the first week of June in their stage of development chart (i.e. ice thickness, where medium green is 70-120 cm thick, dark green 120-200 cm or more):<\/p>\n\n\n\n

Even pessimistic polar bear specialist Andrew Derocher\u00a0admitted last wee<\/a>k that Western Hudson Bay polar bears are largely unaffected by the open water on the bay since they are concentrated in the western half of the bay. The bears do this most years in late spring, in fact, even when there is more ice available. Derocher\u2019s tracking maps for 31 May 2024 and 1 June 2019 are below:<\/p>\n\n\n\n

Overall, however, the NSIDC report also showed that sea ice for May was about what it has been since 2004 (with some variation), with the average this year at 12.78 mkm2:<\/p>\n\n\n\n
