Global Warming Hot Topic Online

A very familiar topic generated significant attention in the blogosphere last week. But this time, the conversation largely emanated from a different side of the political and policy spectrum.

For the week of November 8-12, 17% of the news links on blogs were about global warming, making it the No. 2 subject, according to the New Media Index from the Pew Research Center's Project for Excellence in Journalism. This marks the 10th week since the NMI began in January 2009 that the subject has ranked among the top five stories on blogs. In the past, climate change skeptics dominated the discussion. But last week, it was the believers - and they rallied behind news that 700 scientists are about to become more aggressive advocates for that view.
