Too Many Polar Bears or … Can We Shoot More?

Too Many Polar Bears … or killing 600 a year isn’t keepin the numbers in check … or The Inuit want to sell  more hides.

There are too many polar bears in parts of Nunavut and climate change hasn’t yet affected any of them, says a draft management plan from the territorial government that contradicts much of conventional scientific thinking.

The proposed plan — which is to go to public hearings in Iqaluit on Tuesday — says that growing bear numbers are increasingly jeopardizing public safety and it’s time Inuit knowledge drove management policy.

“Inuit believe there are now so many bears that public safety has become a major concern,” says the document, the result of four years of study and public consultation.

“Public safety concerns, combined with the effects of polar bears on other species, suggest that in many Nunavut communities, the polar bear may have exceeded the co-existence threshold.”

Polar bears killed two Inuit last summer.

The plan leans heavily on Inuit knowledge, which yields population estimates higher than those suggested by western science for almost all of the 13 included bear populations.

Scientists say only one population of bears is growing; Inuit say there are nine. Environment Canada says four populations are shrinking; Inuit say none are.

Canada May 2013 – Nunavut Daily Anomalies

Nunavut (northern Canada) was the coldest Province/Territory in May.

Environment Canada calculates “Normals” for a subset of stations. Those are the anomalies from the 1971-2000 average.

The following barplots are of the daily anomalies (TMax and TMin) for each Nunavut station (that have Normals) averaged together.

The coldest part of the month was 6 to 7C below the 1971-2000 average. So much for the overheating Arctic.

Nunavut (Canada’s Arctic) Temperature Falling From -8C to -12C Per Decade For Last 3 years

Yes Canada’s Arctic has warmed. I blogged about it most recently here. Many stations have a big spike around 2010.

What has happened since then?

I looked at Nunavut stations with Normals (anomalies) calculated by Environment Canada that have data for the last 3 years. (Most recent Nunavut Data Here. I’m looking at stations with data in column D)

Temperature is falling. From -8C to -12C per decade. Amazing.

Sure. Only 3 years. But did anyone else tell you this news? (Click to make bigger)
