Global warming denial turns to skepticism | The Asbury Park Press NJ
Penn State University geophysicist Michael E. Mann, who directs the university’s Earth System Science Center and is a leader in global climate studies, warns that 2 meters of sea-level rise globally is a possibility this century. And if the global average is 2 meters, coastlines along the mid-Atlantic would see higher figures.
“Clearly 2 meters of sea level rise in less than a century would require changes that may very well exceed our adaptive capacity,” Mann said recently in an email response to questions. “And to avoid that, we need to avoid 2C [two degrees Celsius] warming.
“In order to do that,” he said, “we likely have to bring global carbon emissions to a peak within the next few years, and ramp them down dramatically by about 4 to 5 percent per year for the next several decades.”
