Could AI Be Useful for Arctic Communities Facing Sea Ice Loss?

by Humberto Basilio 28 October 202121 March 2022

The forecasting tool IceNet promises to be a useful tool for evaluating sea ice loss in the Arctic. But ethical and logistic considerations have to be taken before scientific and Indigenous communities start working together.

Melting Arctic Sea Ice Strengthens Tides

by Kimberly M. S. Cartier 21 October 202124 January 2022

If climate change throws off the seasonal freeze-thaw cycle of Arctic sea ice, it could trigger a reinforcing cycle of sea ice melt in parts of the Canadian Arctic.
