Author Dennis E. Hedke is a geophysicist and past president of the Geophysical Society of Kansas and the Kansas Geological Society. He has served as a board member of the Kansas Geological Foundation and is a member of the Denver Geophysical Society and Geophysical Society of Houston.
In this paper, Hedke reports and analyzes real data collected from ten coastal cities with long and reliable sea-level records. Those cities are Ceuta, Spain; Honolulu, Hawaii; Atlantic City, New Jersey; Sitka, Alaska; Port Isabel, Texas; St. Petersburg, Florida; Fernandina Beach, Florida; Mumbai/Bombay, India; Sydney, Australia; and Slipshavn, Denmark. He concludes:
The ten case studies of sea-level rise at coastal cities, broadly representative of sites around the world, and the brief analysis that followed undercut a widely repeated but scientifically debunked claim in the climate change debate.
