Since 2000, the Arctic’s Hudson Bay has cooled by -0.35°C with 10 out of 15 sites gaining sea ice – Rise thanks to that?

A new study (Gupta et al., 2022) indicates that between 2000-2019 73% of the 15 sites are considered to have cooled, and 67% have experienced prolonged sea ice periods.

Canada’s Hudson Bay extends to the Arctic Ocean and its shores are filled with polar bears.

Scientists report 11 out of 15 Hudson Bay sites have cooled since 2000. The average temperature for these 11 sites is -0.34°C per decade.

Cooling °C per decade, 2000-2019

Chesterfield Inlet: -0.25 °C

Tatnum tip: -0.3°C

Fort Severn: -0.5°C

Peawanuck: -0.5°C

Attawapiskat: -0.3°C

Chisasibi: -0.3°C

Sanikiluaq: -0.15°C

Inukjuak: -0.4°C

Akulivik: -0.4°C

Ivujivik: -0.45°C

Coral Harbor: -0.65°C

Four locations have warmed since 2000, averaging 0.24°C per decade.

Warming °C per decade, 2000-2019

Rankin Input: 0.2°C

Arviat: 0.4°C

Churchill: 0.15°C

Moosonee: 0.2°C

All 15 locations combined show an overall cooling trend of -0.183°C per decade, or -0.35°C, from 2000-2019 for this region.

Of the 11 cooled sites, 10 experienced extensive sea ice (earlier freezing and/or later thawing) over a 19-year period.

“Annual trends in rapid ice times for 2000–2019 (Figure 2d) show that rapid ice times along the west coast of Hudson Bay are decreasing at a rate of 1–6 days per decade. All other locations on Hudson Bay and James Bay, with the exception of Moosonee, experienced rapidly increasing glacial periods.. This increase was particularly noticeable in Sanikiluaq and Chisasibi, where rapid ice times increased by 9 and 6 days per decade, respectively. “
