Despite climate change, polar bears thrive

Observations: Polar Bears Continue To Thrive, Grow In Number, Shredding Forecasts Of Climate Doom

Ten years ago, polar bears were classified as an endangered species due to model-based assumptions that said the recession of Arctic sea ice would hamper the bears’ seal-hunting capabilities and ultimately lead to starvation and extinction.

The Inuit, who have observed these bears catch seals in open water for generations, disagree.  At least this is what scientists have found upon investigation.

There is no evidence that the fast reduction of sea-ice habitat in the area has yet led to a reduction in population size” (Aars et al., 2017 ).
Inuit observations: “… back in early 80s, and mid 90s, there were hardly any bears … there’s too many polar bears now.  Bears can catch seals even—even if the—if the ice is really thin … they’re great hunters those bears … they’re really smart … they know how to survive” (Wong et al., 2017).

 

Sometimes the “Western scientific understanding” of how the natural world operates conflicts with observations.

The view of polar bears as effective open-water hunters is not consistent with the Western scientific understanding that bears rely on the sea ice platform for catching prey (Laforest et al., 2018).

 

The paleoclimate evidence, which shows that sea ice was thinner and less extensive than today for most of the last 10,000 years, also contradicts the assumptions about modern polar bear endangerment due to thinning ice.  One must ask: How did polar bears survive sea ice free summers in the ancient past if they existentially rely on thick sea ice to hunt prey today?

When the observations don’t agree with the models and assumptions, real scientists are supposed to reconsider their hypotheses.

Climate scientists, on the other hand, too often discard the data that conflict with their modeled assumptions and proceed to call those who question their models and assumptions names (i.e., “deniers”).

This begs the question: Why is climate science so much different than real science?

In the 3 new papers referenced below, extensive observational evidence suggests that polar bear populations are currently healthier than in the past, and their numbers have been stable or growing in recent decades.
