600-year-old marine sponge holds centuries old climate records By Diana Udel Temperature records show past volcanic activity, current climate warming trends MIAMI—Scientists used a 600-year-old marine sponge to reconstruct a record of ocean temperature in the North Atlantic revealing past volcanic activity as well as the current global warming trend from the release of carbon dioxide and other heat trapping gasses into Earth’s atmosphere and absorbed by the oceans. The University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led research team used geochemi...
