Discover is a science magazine. DiscoverBlogs is a science blogging site. And as far as I can see, pretty much everybody here accepts the well established scientific consensus on global warming, which is that it is real and human caused. Whenever I blog about the matter, though, there is always a cascade of denialist/skeptic comments, frequently of enough magnitude to overwhelm the pro-science commenters. That cascade has been particularly pronounced as I've blogged more and more about "ClimateGate," but it has been a smouldering fire for a long time. And as far as I can tell, although we have gotten some anti-climate science links, such as from Morano, they are not sufficient to explain the phenomenon. So here's my somewhat befuddled and honestly, generally curious question--and I really don't have an answer to it--do a lot of regular online readers of Discover doubt the science of global warming? Or, alternatively, are a lot of the "skeptics" that we're getting here non-regular readers who are coming from elsewhere for some reason?
