Climate change blamed for bears’ active winter

Bears have stopped hibernating in the mountains of northern Spain, scientists revealed, in what may be one of the strongest signals yet of how much climate change is affecting the natural world.
Many of the 130 bears in the Cantabrian mountains — which have a slightly different genetic identity from bear populations elsewhere in
the world — have remained active throughout recent winters, according to naturalists from Spain’s Brown Bear Foundation.

The change is affecting female bears with young cubs, which now find there are enough nuts, acorns, chestnuts and berries on the bleak
mountainsides to make winter food-gathering sorties "energetically worthwhile", the scientists said.
