Don’t expect to hear this news from polar bear activists busy promoting the supposed threat to polar bears from declining Arctic sea ice but ice cover over Hudson Bay so far this summer has been very similar to what it was in the 1980s – often promoted as ‘the good old days’ for Western Hudson Bay polar bears. As of the end of June 2020, very concentrated ice (9/10-10/10) more than 1 metre thick still covered most of the bay and there was still no open water near Churchill along the west coast down into James Bay.
Polar bear activists don’t like to have current Hudson Bay sea ice reality ruin their social and news media narrative that ‘polar bears are all gonna die’, so they instead emphasize the obsolete ‘declining trend’ for Western Hudson Bay breakup dates that haven’t been updated since 2015 (e.g. Castro de la Guardia et al. 2017; Lunn et al. 2016). They do this despite the fact their colleagues admit polar bears don’t catch many seals after late June (regardless of sea ice conditions) because it is past the peak spring feeding period (Obbard et al. 2016; Lippold et al. 2019). Like in the 1980s, in 2015 and 2019 some bears stayed on the ice until early August and 2020 is shaping up to be another 1980’s-like summer.
