Beware children, polar bears are invading homes
As Arctic ice thins, which is linked to climate change, the animals move ashore, ravenous
A‘mass invasion’ of polar bears is terrorising an island town. Climate change is to blame. Fences have risen around kindergartens. Special vehicles transport military personnel to their work sites. Residents of the island colony are afraid to leave their homes.
Novaya Zemlya is a Russian archipelago stretching into the Arctic Ocean. It once played host to Soviet nuclear tests, including the largest-ever man-made explosion, when the so-called King of Bombs detonated in 1961.
Today, the barren landscape is under siege — from dozens of polar bears locked in their very own sort of hot war.
Officials in the Arkhangelsk region, where the archipelago lies, on Saturday declared a state of emergency because of the marauding mammals. Polar bears are typically born on land but live mostly on sea ice, where they hunt and feed on seals. But as arctic ice thins, which is linked to the acceleration of climate change, the animals move ■ ashore, ravenous. They scavenge, sometimes coming into contact with human populations.
At least 52 bears were massed near Belushya Guba, the main colony on the island territory, which is still used as a military garrison, with restricted access to the public. The town had a population of about 2,000 as of the 2010 census.
Now, they could be selectively slaughtered if Russian authorities can’t figure out another way to keep them from menacing the residents of the remote island outpost, where they began to collect in December 2018. Warning of the “mass invasion of polar bears in residential areas”, local officials vowed action in response to “numerous oral and written complaints demanding to ensure safety in the colony.”
“I have been in Novaya Zemlya since 1983, but there has never been so many polar bears in the vicinity,” said Zhigansha Musin, a local administrative head, according to Tass, Russia’s state news agency.
Tass reported that the animals had tried to enter office buildings and residential quarters, and that they had chased residents and engaged in other aggressive behaviour. Photos and video footage posted over the weekend showed polar bears parading through drab living spaces, appearing on playgrounds, staring down dogs and feasting on garbage.
“The people are scared,” regional officials reported in a statement. “They are frightened to leave homes and their daily routines are broken. Parents are afraid to let the children go to school or kindergarten.” ■
Residents are barred from hunting the animals, which are classified as a vulnerable species because of the “ongoing and potential loss of their sea ice habitat resulting from climate change,” according to the World Wildlife Fund. The International Union for Conservation of Nature estimates that there are currently somewhere between 22,000 and 31,000 polar bears worldwide.
So far, Russia’s environmental watchdog has withheld licences for shooting the troublesome animals. Instead, a team of experts is being sent to the remote island community to try to protect the residents. “However, provided that those measures do not help solve the situation, a cull will remain the only and forced answer,” Tass reported.
The polar bears are battling adverse conditions of their own, driven by changing conditions in the Arctic, which is warming more than twice as fast as the rest of the planet, according to a 2013 study in the journal Nature. Models suggest that arctic sea ice is declining at a rate of nearly 13 per cent per decade.
The animals wreaking havoc on Novaya Zemlya ventured inland on the southern end of the archipelago, where the ice is rapidly thinning, Ilya Mordvintsev, a researcher at the Severtsov Institute of Ecology and Evolution, told Tass. On their way north, where the ice is thicker, they came across alternative sources of food at Belushya Guba and stopped to feed on the waste.
But a garbage-based diet won’t properly nourish polar bears, whose energy demands require “high-fat prey,” as detailed in a 2014 paper in the journal Science. The marine animals are highly vulnerable to climate change, the authors found, because of their dependence on icy conditions in acquiring their preferred fare, seals, as well as other animals that sustain them, including fish and waterfowl.
The US Geological Survey warned in 2007 that two-thirds of the global population of polar bears could be wiped out by 2050 because of thinning sea ice.
The marine invasion in Russia, is a stark warning on the dangers posed by climate change. ■
