Rising oceans -- too late to turn the tide?

A University of Arizona-led team found that rising sea levels during the Last Interglacial Period were primarily driven by melting ice sheets, rather than thermal expansion. The study suggests that even small amounts of warming may have committed to more ice sheet melting, and sea levels will continue to rise for a long time.
