Canadian climatologist Andrew Weaver is suing the National Post for libel based on its continuing reporting on Weaver’s climate advocacy. Ars Technica has details. Interestingly, Weaver also seeks copyright to the material in question so he can force bloggers to remove it from the internet. This will be a fascinating case to watch. If it follows the pattern of most American legal actions, the National Post will have the opportunity to force disclosure by Weaver of any relevant evidence including e-mails pertinent to his climate change advocacy.
