First and last, the purpose of Blog Action Day is to create a discussion. We ask bloggers to take a single day out of their schedule and focus it on an important issue.

By doing so on the same day, the blogging community effectively changes the conversation on the web and focuses audiences around the globe on that issue.

Out of this discussion naturally flow ideas, advice, plans, and action. In 2007 on the theme of the Environment, we saw bloggers running environmental experiments, detailing innovative ideas on creating sustainable practices, and focusing their audience's attention on organizations and companies promoting green agendas. In 2008 we covered the theme of Poverty, and similarly focused the blogging community's energies around discussing the wide breadth of the issue from many perspectives and identifying innovative and unexpected solutions. This year we aim to do the same for Climate Change, an issue that threatens us all.
