Please understand, I don’t shy away from openly presenting the facts about the changing climate and rising seas. But I’ve learned that doing so is not without risk.

In 2010, I was a co-author of a report for North Carolina’s Coastal Resources Commission that said sea levels along the state’s coastline could rise by as much as 39 inches by the end of the century. That conclusion was based on the best peer-reviewed science and was intended to help policy makers plan for the future.

But it alarmed real estate and other economic development interests, which quickly attacked the report. The coastal commission ignored it. The authors, myself included, were widely slandered. And the Legislature passed a law that barred state and local agencies from developing regulations or planning documents anticipating a rise in sea level. “I think this is a brilliant solution,” the comedian Stephen Colbert said at the time. “If your science gives you a result that you don’t like, pass a law saying the result is illegal. Problem solved.”

You might think that the lesson I learned from that experience was to distrust the political establishment. No. What I learned was that most of those attacking our sea-level-rise projections had never met me, nor my co-authors. Not only that, most of the public had never met anyone they considered a scientist. They didn’t understand the careful, painstaking process we followed to reach our peer-reviewed conclusions. We were unknowns, “scientists” delivering bad news. We were easy marks for those who felt threatened by our findings.

A march by scientists, while well intentioned, will serve only to trivialize and politicize the science we care so much about, turn scientists into another group caught up in the culture wars and further drive the wedge between scientists and a certain segment of the American electorate.
