Researcher estimates future sea level rise by looking to the past

(PhysOrg.com) -- Boston University College of Arts & Sciences Paleoclimatologist Maureen Raymo and colleagues have published findings that should help scientists better estimate the level of sea level rise during a period of high atmospheric carbon dioxide levels 3 million years ago. That geologic era, known as the mid-Pliocene climate optimum, saw much higher global temperatures that may have been caused by elevated levels of carbon dioxide—an analogy for the type of climate we are causing through human addition of greenhouse gases to the atmosphere.
