(alternate title: Proceedings of the 20th National Cave and Karst Management Symposium)
The 20th National Cave and Karst Management Symposium (NCKMS) is celebrated in these proceedings with 29 high quality papers in this 175-page volume. The papers span seven countries, four continents, and topics that range from the geological, biological, and paleontological sciences, to public education, inventorying, monitoring, and managing of caves and karst. Many papers focus on this year's theme, "A Changing Climate." They examine how changes in the technological, social, and economic climates, as well as climatological climate change, is affecting caves and karst and their study and management.
