Today is Blog Action Day, an annual event in which participating bloggers post about a particular issue to raise awareness and trigger global discussion that will - hopefully - bring about positive change. This year's topic is climate change - which, shall we say, is a wee bit controversial.

We'll get to some Neatorama-worthy posts on the blog today, but first I'd like to ask YOU what you think about global warming/climate change. Do you believe that it is happening? Or is it just a passing hysteria, much like the concern over global cooling in the 1950s to 1970s?

It's an open mike - let's hear your opinion.
