Talk:Controversies in Science/Are humans causing global warming/A critique of Possible Impacts of Climatic Warming on Polar Bears

While it is extremely upsetting that the polar bears are being effected by globally warming, this article offers no explanation for the cause of global warming. This article can not be proof that humans are responsible because it does not offer any causal infomation. Patricia D B (talk) 20:41, 17 October 2012 (UTC)
