Earth Day 2021: celebrate abundant sea ice habitat for polar bear feeding and mating

Sea ice charts below. Compare to 2018 conditions here; 2015 here; and 2014 here. Sea ice maximum this year was apparently “uneventful” according to the folks at the NSDIC because it didn’t even come close to setting a new low record.
