ClimateTV.tv, the Vancouver-based Internet television station launched earlier this month, is running a "marathon" of global warming coverage for Earth Day today.

Among the offerings, this interview with the Nobel-prize winning University of Victoria climate scientist, Andrew Weaver, who has just filed a lawsuit against The National Post.

Climate TV was founded by Nick Miller, who is an Al Gore Climate Project presenter and businessman. He has developed an online television platform called Xool Labs, which runs ClimateTV, according to Kimberly Thee, who produces shows for the station.

The project also is being helped along by Kevin Grandia, managing editor of DeSmogBlog.com, an online source for global warming-related news that aggressively debunks climate-change deniers.

"ClimateTV is a new way to communicate on this important issue. Video is king online, but the threshold to doing live and interactive HD quality television on the internet has always been prohibitively high. But we're at the point now where we can produce TV-quality shows and communicate direct to our audiences without relying on an overworked and often bias traditional media," Grandia says.

All ClimateTV shows are archived and available on the site.

Today at 3:30 ClimateTV will air the documentary No Impact Man, followed at 5 by a live panel discussion, hosted by Grandia, that will include New York-based Jennifer Prediger, better know as "Ask Umbra" on Grist, the environmental online news magazine, and Tyee editor David Beers.

"Not only is the show run live in high-definition, it is also totally interactive -- meaning that viewers can weigh in with questions and comments throughout the show for us to discuss and respond," says Grandia.
