Churchill, Canada – Here on the edge of the Arctic in Northern Canada, the annual migration of polar bears attracts Jeoff York, such as tourists, photographers and scientists.
The garden crossed the frozen area, so that tourists could actually be brought closer to the wild. Polar bears pass through Churchill, Manitoba, who expects to catch a ride out of the small town on Hudson Bay’s sea ice.
After the summer of fasting on the ground, the bear needs to go back to his frozen home to seal and bulk up.
“They are just dreaming of snow and going back there,” said York, Senior Director of Research and Policy with Conservation Group Polar Beer International.
But this migration ritual is changing. Arctic According to a study published in 2022 in Journal Nature, it is almost four times faster than the rest of the world.
“One of the fastest warming regions in the Arctic planet,” said Flavio Lehanar, the main climate scientist of Polar Beer International and Assistant Professor at the University of Cornell, said that it suggests that it is melting sea ice that depends on the bear.
“This is important, because it is a complete change of ecosystem,” said Lehner.
Western Hudson Bay Polar Bears are away from snow for a month compared to their parents and grandparents. This damages the ability of their prey and healthy cubs that make it in adulthood.
According to Polar Beer International, this is a change that has reduced this population in 40 years.
“This is actually difficult to find other places, perhaps in addition to places that are probably dictors in Amazon, where you see such a clear change,” said Lehanar.
And what happens to all of us in the Arctic Trick.
“If the sea ice disappears, the Arctic will warm rapidly and the planet will be rapidly heated,” Lehner said.
That ice Can be thought of Earth’s air conditioner. This reflects light and heat from our water. Without it, the sun is absorbed and heats the oceans.
Scientists say that to slow down the melting, we need to cut emissions significantly from fossil fuels.
“Arctic is just an indicator for me what we are likely to be,” York said. “This is the way of nature that we need to do something.”
