Shift in perception noted at climate change event | | The Bulletin

About 300 people gathered in a Portland State University ballroom Tuesday night to hear three Oregon climate scientists make their case that increases in manmade greenhouse gases are driving climate change.

The event hosted by the Oregon chapter of the American Meteorological Society, was open to the public. It came in response to a January panel of global warming skeptics hosted by the chapter that event organizers estimated drew about 500 people.

The audience flip-flopped from January, when mostly skeptics attended. Chapter President Steve Pierce asked for a show of hands beforehand Tuesday evening, then estimated that at least 90 percent of the crowd favored the statement that human activities are the main cause of global warming.
