A group of activists and scientists will gather tonight in Vancouver to debate whether human activity is responsible for global climate change.

The forum will include three panelists arguing in favor of the notion of human-caused climate change: Ryan Rittenhouse, a local activist; Daphne Wysham, a climate policy fellow at the Center for Sustainable Economy; and Kyle Dittmer, a hydrologist and meteorologist with the Columbia River Inter-Tribal Fish Commission.

Three panelists will make the case against human-caused climate change: Don Easterbrook, a geology professor at Western Washington University; Nils Morner, a retired professor at Stockholm University; and Gordon Fulks, a physicist.

The event begins at 6 p.m. today in the Vancouver Community Library, 901 C St.

The debate was organized by local activist Don Steinke and Vancouver City Council member Bill Turlay. The event, which will be broadcast on CVTV, is not sponsored by the city.
