More “polar bears are all going to die” drivel from the BBC:
High-tech tracking collars on nine female polar bears have measured the animals’ efforts to find food on the diminishing Arctic ice.
Each bear wore a collar – recording video, location and activity levels – for 8-12 days, while metabolic tracers tracked the bears’ energy use.
This revealed that most of the animals were unable to catch enough prey to meet their energy needs.
The team says wild bears have higher metabolic rates than thought.
Moreover, climate change appears to be having dramatic effects on the Arctic sea-ice, forcing polar bears to move greater distances as they hunt, and making it harder for them to catch prey.
