An analysis of dozens of blogs that question the threat climate change poses to polar bears has found those publications ignore virtually all the science on both the bears and sea ice.
The study, published today in the journal BioScience, suggests the blogs attempt to use that doubt to cloud the entire consensus around climate change.
And it found that a zoologist at the University of Victoria is a main source of the arguments they do use.
The analysis looked at 90 different blogs, evenly split between those supporting the consensus and those who deny climate change.
It found the science quoted in the blogs bore little resemblance to the conclusions of 92 peer-reviewed papers on polar bears and sea ice.
It also found 80 per cent of denier blogs cited the work of Susan Crockford at UVic, despite the fact she has published almost nothing on polar bears.
