Al Gore speaks to a packed AAAS session at Chicago's Fairmont Hotel. by Dennis Dimick
Self-described "recovering politician" Al Gore brought his campaign against human-induced climate change into the belly of the scientific beast February 13.
Speaking in Chicago to thousands of scientists at the annual meeting of the American Association for the Advancement of Science (AAAS), the former vice-president showed an updated slide show with pictures and charts of recent floods, fires, and disappearing ice at both poles.
He also showed clips of several advertisements from his Alliance for Climate Protection which campaigns for alternative energy and against coal.
What was striking was Gore's call to action. This to a group with more accumulated knowledge about the cause and effects of global warming than any other, but also with more reticence than any other group to speak forcefully and clearly about what they know.
As Stanford climate scientist Stephen Schneider said earlier in the day to a session on media coverage of climate change, "We lead with our caveats."
Gore pleaded with the scientists to get involved in public education on the issues, to no longer separate the work they do from the civilization they live in.
"This is no time to sit back. This is a historic struggle. We as a species must make a decision," Gore said. "We've now reached a stage where continuing on our present course would threaten the entirety of human civilization.
"We have to go far quickly. And the only way that's going to happen is if those of you who are in a position to exercise influence and communicate your understanding of what this is all about make a decision to get involved. We need you to be actively involved.
"Scientists can no longer in good conscience accept this division between the work you do and the civilization in which you live. I'm asking you for help.
"I believe in my heart that we do have the capacity to make this generation one of those generations that changes the course of humankind. The stakes have never been higher."
The scientists could also take some cues from the presentation style of Gore's slide show, designed by Duarte Design. Bad powerpoint-style presentations dominate at meetings like this, the slides larded with poor-quality pictures, inscrutable graphs, charts, and hundreds of data points.
In that sense scientists are their own worst enemies when communicating clearly and effectively.
Better presentations are a good start to more effective communication about scientific work and findings. Scientists, and anyone, wanting to communicate more powerfully could start by reading Garr Reynold's book Presentation Zen, Nancy Duarte's book slide:ology, or Edward Tufte's essay, The Cognitive Style of Powerpoint.
