Nov 26th, 2018: Wrangel Island
Wrangel Island is Russian and looks like they’re a little unfriendly towards the neighbors.
But these are the neighbors.
Quote:
Wrangel Island, in the Arctic Ocean, is one of the most remote islands in Russia. Straddling the International Date Line—the boundary where the eastern and the western hemisphere meet—this rugged volcanic island, where summer temperatures barely climb above freezing, is believed to have been the last place on earth where the wooly mammoth survived, six thousand years after their cousins on the mainland disappeared. This harsh landscape supports a surprisingly diverse ecosystem, including Arctic foxes, seals, walrus, musk oxen, lemmings, and many types of birds. But the most abundant species here is the polar bear.

Wrangel Island has the highest density of polar bear dens in the entire Arctic region. The bears come here every summer when the ice melts, and stay on the island until winter and the start of the next freezing cycle. The bears also come here to give birth and raise cubs and prepare them for the next winter.
But in the past few decades, change in the climate has forced the bears to spend more and more time on land because the ice now melts earlier and freezes later, elongating the ice-free period. Compared to 20 years ago, polar bears now spend, on average, a month longer on Wrangel Island. The number of bears that arrive on Wrangel Island each year is also increasing. In 2017, researchers counted 589 bears on the island, which was “abnormally higher” than the previous average of 200-300 individuals.
