Corrigendum: Internet Blogs, Polar Bears, and Climate-Change Denial by Proxy (BioScience 68 (281-287))

This paper has been corrected online and in print in order to clarify Dr. Crockford's scientific expertise and financial links in relation to the arguments made in the paper (BioScience 68: 281-287). The corrected text is as follows: First change: Notably, as of this writing, Crockford has neither conducted any original research nor published any articles in the peer-reviewed literature on the effects of sea ice on the population dynamics of polar bears. Second change: Some of the most prominent AGW deniers, including Crockford, are linked with or receive support from organizations that downplay AGW (e.g., Dr. Crockford has previously been paid for report writing by the Heartland Institute). The authors apologize for any confusion.
